AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
555 AM EDT FRI JUL 25 2014

.SYNOPSIS...
HIGH PRESSURE AND WEAK WINDS INTO FRIDAY. STRONG WARM AIR ADVECTION
SATURDAY. A SERIES OF DISTURBANCES IN A WEST/NORTHWEST FLOW ALOFT
WITH ROUNDS OF CONVECTION MAINLY SATURDAY NIGHT THRU SUNDAY NIGHT.

&&

.NEAR TERM /THROUGH TONIGHT/...
VAD WINDS AT 925 MB BLOWING A BIT STRONGER AT 08Z...THAN WAS
FIGURING. KRLX FOR EXAMPLE WAS 15 TO 20 KNOTS. BUT STILL FIGURING ON
IT TO BE WEAKENING THROUGH DAWN.  HAVE AREAS OF FOG OR LOW STRATUS
CLOUDS IN THE WESTERN SLOPES...MOSTLY FROM SUTTON AREA ON S AND SW
TO THE TUG FORK BORDER WITH EASTERN KENTUCKY. SOME EVAPORATING/
SHRINKING AREAS OF LOW CLOUDS STILL POSSIBLE AT 13 TO 14Z IN THESE
WESTERN SLOPES AREAS.

OVER SOUTHERN MOUNTAINS...ALSO FIGURING ON PATCHES OF FOG AND LOW
CLOUDS THROUGH DAWN...THEN LIFTING A BIT SOONER INTO SCATTERED
CLOUDS.

FURTHER WEST AND NORTH...IN THE COOLER AIR...MAYBE SOME PATCHY FOG
ALONG WATERWAYS 11-12Z.

HAVE SUBSIDENCE INVERSION AT THE TOP OF THE MIXING LAYER AROUND 5
THSD FT MSL TODAY.  WITH LIGHT WINDS TODAY...FIGURING ON LIMITED
MIXING...SO DID NOT MAKE ANY BIG ADJUSTMENTS UPWARDS IN THE MAXIMUM
TEMPERATURE FORECAST FOR TODAY.  DEW POINTS IN THE SOUTH SHOULD
STILL LOWER A BIT THIS AFTERNOON.

PICTURING A FAIRLY PLEASANT LATE JULY FRIDAY EVENING.  HAVE JUST
SOME HIGH CLOUDS STREAKING IN OVERNIGHT.  ANY FOG DURING THE LATE
NIGHT AND EARLY SATURDAY MORNING HOURS SHOULD BE LIMITED TO THE
DEEPER MOUNTAIN VALLEYS.  BOUNDARY LAYERS WINDS START TO INCREASE
06Z TO 12Z SATURDAY IN THE OHIO VALLEY COUNTIES.

&&

.SHORT TERM /SATURDAY THROUGH MONDAY NIGHT/...
THERE IS REASONABLE MODEL AGREEMENT ON THE MASS AND QPF FIELDS THIS
PERIOD...INDICATING A VERY UNSETTLED PERIOD. THE PATTERN UNDERGOES
AMPLIFICATION...WITH THE SOUTHERN EDGE OF THE WESTERLIES ACROSS THE
OHIO VALLEY TRANSITIONING INTO A MEAN EASTERN U.S. UPPER TROUGH. ONE
SHORT WAVE TRACKS ACROSS THE GREAT LAKES SATURDAY...DRAGGING A WARM
FRONT NORTHEAST ACROSS THE AREA. BELIEVE THE MODELS ARE ON THE RIGHT
TRACK IN KEEPING MOST OF THE CONVECTION ASSOCIATED WITH THIS FRONT
NORTH OF THE AREA...ESPECIALLY AS THE VIGOROUS SOUTHWEST TO WEST 850
MB LOW LEVEL JET STAYS GENERALLY TO THE NORTH AT THIS TIME. WILL PUT
LOWER CHANCE POPS NORTH SATURDAY...AND KEEP THE SOUTH DRY. WITH MORE
SUNSHINE AND SOUTHERLY FLOW...EXPECT TEMPERATURES SATURDAY TO REACH
INTO THE MID AND UPPER 80S WITH INCREASING HUMIDITY.

SATURDAY NIGHT INTO SUNDAY NIGHT LOOK TO BE QUITE STORMY AND
WET...AHEAD OF A SIGNIFICANT COLD FRONT THAT WILL CROSS THE AREA
LATER SUNDAY NIGHT AND EARLY MONDAY. GOOD UPPER DYNAMICS FROM A
VIGOROUS SHORT WAVE SUPPORTING THE COLD FRONT...WILL COMBINE WITH
PW`S AROUND 2 INCHES AND A MODERATE LOW LEVEL WESTERLY 850 MB JET
AHEAD OF THE FRONT...TO BRING WIDESPREAD SHOWERS AND THUNDERSTORMS.
A FEW OF THE STORMS MAY BE SEVERE PER SPC OUTLOOK...WITH LOCALLY
HEAVY RAINS. HOWEVER...ALTHOUGH THE MODELS DRAG HEAVY QPF AMOUNTS
RIGHT ACROSS OUR AREA...IF THE ANTICIPATED MCS`S DROP SOUTHWARD TO
THE WEST OF OUR AREA PER 1000-500 MB THICKNESS ORIENTATION...THAT
WOULD DRASTICALLY LESSEN THE RAIN AMOUNTS FOR OUR AREA. THUS...WILL
STICK TO A PROLONGED PERIOD OF POPS IN THE LIKELY RANGE. THIS WILL
STILL WARRANT MENTION OF POSSIBLE WATER PROBLEMS IN THE HAZARDOUS
WEATHER PRODUCT...ALONG WITH POSSIBLE SEVERE STORMS.

MONDAY WILL BE THE TRANSITION DAY AS THE COLD FRONT EXITS...WITH
PRECIP DECREASING FROM WEST TO EAST AND MUCH COOLER TEMPERATURES
OVERSPREADING THE AREA.

&&

.LONG TERM /TUESDAY THROUGH THURSDAY/...
LINGERING SHOWERS ARE POSSIBLE AS THE LAST SHORTWAVE EXITS THE
EASTERN MOUNTAINS. GRADUALLY REDUCED POPS SUNDAY NIGHT INTO EARLY
MONDAY MORNING. ANOTHER COLD FRONT APPROACHES THE AREA FROM THE
NORTHWEST EARLY MONDAY MORNING...KEEPING THE POSSIBILITY FOR MORE
PCPN.

HIGH PRESSURE BEHIND THE COLD FRONT TAKES CONTROL LATER MONDAY
THROUGH THE MIDDLE OF NEXT WEEK WITH NEAR NORMAL TEMPERATURES.

FUSED A BLEND OF
DIFFERENT GUIDANCE...KEPT WARMER TEMPS FOR A MUGGY SUNDAY NIGHT.
LOW TURN NORTHWEST BY MONDAY BRINGING COOLER PLEASANT TEMPERATURES
DURING THE FIRST HALF OF THE WEEK.

&&

.AVIATION /10Z FRIDAY THROUGH TUESDAY/...
HIGH PRESSURE AND WEAK WINDS INTO TONIGHT.

HAVE WIDESPREAD FOG OR LOW STRATUS FROM KEKN ON SW TO KCRW INTO THE
SOUTHERN WV COAL FIELDS AND BUCHANAN AND DICKENSON COUNTIES IN VA
FOR DAWN.  SO EVEN THOUGH KCRW HAS BEEN REPORTING SCATTERED CLOUDS
DURING THE PREDAWN HOURS...CAN STILL SEE THEM GETTING A CEILING.
FURTHER NORTH AND WEST...ONLY A FEW PATCHES OF FOG FIGURED JUST
ALONG RIVERS IN THE COOLER AND DRIER AIR MASS ALONG ROUTE 50
CORRIDOR...SAY UNI...PKB TO CKB.

IN THE WEAK LOW LEVEL FLOW...FIGURING LOW STRATUS IN THE SUTTON TO
CRW TO HTS AND WILLIAMSON CORRIDOR LINGERING FOR 12Z TO 14Z...AND
BREAKING UP AROUND 14Z TO 15Z.

AFTER A NIGHT OF FOG AND LOW CLOUDS WITH VARIABLE CONDITIONS AT
KBKW...HAVE LOW STRATUS LIFTING AND SCATTERING OUT OVER THE SOUTHERN
PLATEAU AROUND BECKLEY.

AFTER 15Z..MOSTLY SCATTERED CLOUDS AT 3 TO 5 THSD FT AGL.

AFTER 23Z...JUST HIGH CLOUDS AOA 15 THSD FT AGL FOR OVERNIGHT.
SOME IFR IN FOG MAY FORM 06Z TO 12Z SATURDAY IN THE DEEPER MOUNTAIN
VALLEYS OF EASTERN AND SOUTHERN WEST VIRGINIA...INCLUDING ELKINS.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 12Z SATURDAY...

FORECAST CONFIDENCE: MEDIUM.

ALTERNATE SCENARIOS: TIMING THE AREAL COVERAGE OF THE LINGERING LOW
STRATUS IN THE WESTERN SLOPES AFTER 12Z AND HOW QUICKLY IT LIFTS AND
EVAPORATES COULD VARY.

SFC HIGH CENTERED OVER THE NW ZONES BY 12Z FRI. CLOUDS ARE A BIT OF
A TOUGH CALL...WITH THE LATEST NAM RUN DEPICTING SOME TRAPPED LLVL
MOISTURE UNDERNEATH THE STRENGTHENING SUBSIDENCE INVERSION...WHILE
THE RAP/S LATEST RUNS SHOWING MORE ROBUST SCATTERING OF LLVL
MOISTURE...WHICH WOULD ALLOW FOR MORE CLEARING. EXTENSIVE CUMULUS
FIELD NORTH OF OUR AREA LENDS SOME CREDENCE TO EXISTING LLVL
MOISTURE...AND WILL BE INTERESTING TO SEE WHAT 00Z RAOBS IN THOSE
AREAS YIELD. IN SHORT...SHOULD WE CLEAR AS EXPECTED...MORE
FOG/REDUCED VIS WILL TRANSPIRE CENTRAL AND SOUTHERN LOCATIONS.
SHOULD THE CLOUDS BE SLOW TO DISSIPATE/SCATTER...FOG WILL BE LESS
PREVALENT. VERY LITTLE CHANGE FROM PREV FCST REGARDING OVERNIGHT
MINS...RANGING FROM THE LOW 50S NORTHWEST AND MOUNTAINS TO THE UPPER
50S CENTRAL/SOUTHERN LOWLANDS.

FRIDAY...LIGHT VARIABLE WINDS WILL GRADUALLY SHIFT TO THE SOUTH AND
SOUTHWEST AS SFC HIGH PRESSURE CONTINUES OFF TO THE EAST. SHOULD BE
A VERY PLEASANT DAY IN STORE. A PINCH OF LLVL MOISTURE AROUND 850MB
PROBABLY WILL RESULT IN A FLAT-CU SCATTERED DECK...BUT THE AREA
SHOULD REMAIN UNDER MOSTLY SUNNY TO PARTLY CLOUDY SKIES WITH WARM
ADVECTION ENSUING. MAY BE A MORE ROBUST CU-FIELD IN THE EASTERN
MOUNTAINS...AND HIGH/MID LEVEL CLOUDS WILL BE ON THE INCREASE DURING
THE MID/LATE AFTERNOON ACROSS THE NW ZONES AS A RIPPLE WITH LIMITED
MOISTURE MOVES ACROSS THE SOUTHERN GREAT LAKES. HIGHS OF ABOUT 80F
FOR THE LOWLANDS PLUS OR MINUS A COUPLE OF DEGREES STILL APPEAR ON
TRACK...WHICH PREV FCST HAD A GOOD HANDLE ON WITH ONLY MINOR
TWEAKS.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
SURFACE HIGH PRESSURE WILL BE IN CONTROL WITH PLEASANT WEATHER
FRIDAY.

A MID LEVEL SHORTWAVE...EVIDENT IN H5 CHARTS WILL CROSS THE AREA
FRIDAY NIGHT INTO SATURDAY INCREASING CHANCES FOR SHOWERS AND
THUNDERSTORMS. ANOTHER H5 SHORTWAVE WILL CROSS MID DAY SATURDAY
CONTINUING THE THREAT FOR PCPN INTO SATURDAY NIGHT. MINOR TWEAKS
MADE TO POPS THROUGH THE PERIOD AS MODELS HAVE BEEN CONSISTENT FOR
THE LAST FEW DAYS.

FLOW WILL BECOME MODERATE FROM THE SOUTHWEST BRINGING WARM
ADVECTION ALOFT. LEANED CLOSER TO THE MOS CONSENSUS FOR
TEMPERATURES THROUGH THE PERIOD.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
LINGERING SHOWERS ARE POSSIBLE AS THE LAST SHORTWAVE EXITS THE
EASTERN MOUNTAINS. GRADUALLY REDUCED POPS SUNDAY NIGHT INTO EARLY
MONDAY MORNING. ANOTHER COLD FRONT APPROACHES THE AREA FROM THE
NORTHWEST EARLY MONDAY MORNING...KEEPING THE POSSIBILITY FOR MORE
PCPN.

HIGH PRESSURE BEHIND THE COLD FRONT TAKES CONTROL LATER MONDAY
THROUGH THE MIDDLE OF NEXT WEEK WITH NEAR NORMAL TEMPERATURES.

FUSED A BLEND OF
DIFFERENT GUIDANCE...KEPT WARMER TEMPS FOR A MUGGY SUNDAY NIGHT.
LOW TURN NORTHWEST BY MONDAY BRINGING COOLER PLEASANT TEMPERATURES
DURING THE FIRST HALF OF THE WEEK.

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
18Z THURSDAY THROUGH 18Z FRIDAY...

SHOWERS AND EMBEDDED THUNDERSTORMS WILL END ACROSS SOUTHERN HALF
OF THE FORECAST AREA FROM WEST TO EAST...AND SHOULD BE EAST OF THE
MOUNTAINS BY 00Z FRI. IFR CIGS CURRENTLY ACROSS MUCH OF THE REGION
WILL SLOWLY IMPROVE DURING THE COURSE OF THE AFTERNOON AND EVENING
HOURS FROM NORTHWEST TO SOUTHEAST...IMPROVING LAST IN THE EASTERN
MOUNTAINS AS USUAL.

A BIT OF A TOUGH CALL ON LOW STRATUS THIS EVENING...PARTICULARLY
FROM CKB-CRW AND POINTS SOUTH/EAST. DO BELIEVE THAT EVEN HERE LOW
STRATUS WILL EVENTUALLY SCATTER. FOG SHOULD BE A GOOD BET AT LEAST
ACROSS THE CENTRAL LOWLANDS OF WEST VIRGINIA...WITH LESS CERTAINTY
FURTHER WEST AND NORTH NEAR AND WEST OF THE OHIO RIVER WHERE TEMPS
ARE A BIT WARMER TODAY AND DEWPOINTS LOWER.

REDUCTIONS IN VIS AND CIG SHOULD QUICKLY IMPROVE BY THE 14Z-15Z
TIME FRAME AS SFC HIGH PRESSURE MOVES OVERHEAD.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
214 PM EDT THU JUL 24 2014

.SYNOPSIS...
COLD FRONT SINKING SLOWLY SOUTH AS MID LEVEL DISTURBANCE PASSES THIS
MORNING. DRIER AIR REACHES INTO SOUTHEAST OHIO FIRST...THEN CREEPS
FURTHER EAST BY THURSDAY NIGHT.

&&

.NEAR TERM /THROUGH TONIGHT/...
130 PM UPDATE...
AGAIN FINE-TUNED PRECIP AND THUNDER PER LATEST TRENDS. SFC FRONT
HAVING A TOUGH TIME CLIMBING OVER THE HILLS TO THE
SOUTHEAST...WITH THE WIND SHIFT FINALLY MAKING IT THROUGH BKW IN
THE PAST HOUR. BACK EDGE OF THE MAIN PRECIP SHIELD/LINE NOW EAST
OF HTS...AND EXPECT IT TO CONTINUE ACROSS THE SOUTHERN HALF OF THE
CWA AND EXIT THE EASTERN MOUNTAINS BY THE 21Z-22Z TIME FRAME.

1030 AM UPDATE...
SEVERAL UPDATES TO ONGOING FORECAST. UPDATED/TIGHTENED UP POPS TO
REFLECT PERSISTENT BAND OF SHOWERS ALONG AND JUST NORTH OF THE I64
CORRIDOR...WHICH APPEARS TO BE ASSOC WITH THE ELEVATED FRONT. EVEN
HAVE HAD A COUPLE OF LIGHTNING STRIKES NORTHWEST OF CRW IN THE
PAST 30-45 MINS...SO ADDED IN SLIGHT THUNDER AS WELL FROM THERE
AND POINTS SOUTH. THAT SAME STORM CURRENTLY OVER SOUTHERN JACKSON
COUNTY BEARS WATCHING...AS IT IS MAKING A BEELINE STRAIGHT FOR
WEST-CENTRAL BRAXTON COUNTY WHICH RECEIVED A RADAR-ESTIMATED 2.50IN+
OF RAIN EARLIER THIS MORNING. FINALLY...UPDATED THE HOURLY TEMP
CURVE TODAY WITH CONTINUED CLOUD COVER AND WEAK COLD
ADVECTION...EXPECT TEMPS TO REMAIN STEADY OR EVEN DROP A DEGREE OR
TWO BEFORE REBOUNDING MID/LATE AFTERNOON.

PREVIOUS DISCUSSION...
CERTAINLY AN UNUSUAL PATTERN FOR LATE JULY. HAVE SURFACE FRONT
ABOUT ON TIME WITH OUR THINKING 24 HOURS AGO. AROUND
08Z...ANALYZING THE FRONT SOUTH OF EKN TO JUST S OF CRW TO NEAR
JKL AT 08Z. YET...EVEN SOUTH OF THE FRONT...KFCX RADAR HAS A
NORTHWEST FLOW AT 925 MB.

LOCAL DOWNPOURS HAVE BEEN OCCURRING OVERNIGHT.  RAIN RATES
OF .75 IN 15 MINUTES HAVE BEEN MEASURED.  THE HIGHEST 3 HOUR TOTAL
OVERNIGHT...THRU 08Z WAS LATE WEDNESDAY EVENING WAS AN ESTIMATED 3
INCHES ALONG THE BOONE/RALEIGH COUNTY LINE.  SO FAR...NO SIGNIFICANT
FLOODING REPORTS HAVE BEEN RECEIVED.  ALSO CONCERNED ABOUT THE
REPETITIVE CELLS THIS PREDAWN THURSDAY IN CLAY COUNTY.

THE SECONDARY RAIN AREA BETWEEN HTS AND CVG SEEMS TO BE IN THE
850 MB THERMAL GRADIENT NORTH OF THE FRONT.  FIGURING IT WILL MOVE
EAST INTO CENTRAL WEST VIRGINIA THIS MORNING.  ALSO FIGURING WITH
PW(S) LOWERING...THAT RAIN RATES WILL DECREASE THIS MORNING.  IF
NOT...FLASH FLOOD WATCHES OR WARNING MAY BE NEEDED.

WITH 925 MB FLOW TURNING NE...STILL HAVE THE DRIER AIR HAVING A
TOUGH TIME PENETRATING INTO THE HEART OF CENTRAL AND SOUTHERN WEST
VIRGINIA...BUT SHOULD ARRIVE LATE TODAY.  I CAN PICTURE THE SOUTHERN
PLATEAU OF SOUTHERN WV GETTING INTO LOW CLOUDS WITH A DIURNAL
TEMPERATURE SPREAD OF 5 DEGREES.  SO NOT YOUR "CHAMBER OF COMMERCE
DAY" PICTURED FOR PLACES LIKE BECKLEY.

WENT WITH SOME FOG OR LOW STRATUS 06Z TO 12Z FRIDAY IN THE WEST
VIRGINIA VALLEYS.  DID NOT GO QUITE AS CHILLY FROM THE ELK RIVER
VALLEY ON SOUTH INTO THE SOUTHERN COAL FIELDS FOR MINIMUM
TEMPERATURES TONIGHT...THIS INCLUDES KANAWHA VALLEY AROUND CRW.
FIGURING ON THAT FOG AND WET TERRAIN HOLDING READINGS UP.

&&

.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
SURFACE HIGH PRESSURE WILL BRING PLEASANT WEATHER TO END THE WORK
WEEK. SEVERAL 500MB RIPPLES ARE PROGGED TO CROSS THE FORECAST AREA
SATURDAY INTO SATURDAY NIGHT. IT MAY TAKE A WHILE FOR THE ATMOSPHERE
TO MOISTEN BACK UP AS THE HIGH DEPARTS...BUT WITH THE UPPER LEVEL
DISTURBANCES DO HAVE CHANCE POPS ACROSS MOST OF THE FORECAST AREA
SATURDAY AFTERNOON AND SATURDAY NIGHT. MINIMAL CHANGES MADE TO HIGHS
AND LOWS BY BLENDING IN CONSENSUS GUIDANCE.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
TWO DISTINCTIVE SHORT WAVE EVIDENT IN H5 CHARTS WILL CROSS THE AREA
SATURDAY AND SUNDAY...KEEPING CHANCES FOR SHOWERS AND STORMS AT
LEAST PARTS OF UP COMING WEEKEND. THE FIRST COMES ALONG THE BACK
SIDE OF AN UPPER TROUGH AND THE SECOND ONE IN A ZONAL FLOW ALOFT.

MODELS QPF FIELDS KEEP SATURDAY RELATIVELY DRY...AND TARGET MORE THE
SYSTEM ON SUNDAY WITH A VORTICITY MAX IN THE NORTHERN STREAM PASSING
OVER AN OLD FRONTAL BOUNDARY OVER OUR CWA. THE A COLD FRONT
APPROACHES THE AREA FROM THE NORTHWEST EARLY MONDAY
MORNING...KEEPING THE POSSIBILITY FOR MORE PCPN.
THEREFORE...INCREASED CHANCE POPS SATURDAY NIGHT INTO LIKELIES FOR
SUNDAY...AS EXPECTED CONVECTION MOVES EAST SUNDAY NIGHT.

HIGH PRESSURE BEHIND THE COLD FRONT TAKES CONTROL LATER MONDAY
THROUGH THE MIDDLE OF NEXT WEEK WITH NEAR NORMAL TEMPERATURES.

USED A BLEND OF DIFFERENT GUIDANCE...WARMER SATURDAY NIGHT INTO

A COOLER TREND AFTER THE WEEKENDS FRONT.

1048 AM EDT THU JUL 24 2014

.SYNOPSIS...
COLD FRONT SINKING SLOWLY SOUTH AS MID LEVEL DISTURBANCE PASSES THIS
MORNING. DRIER AIR REACHES INTO SOUTHEAST OHIO FIRST...THEN CREEPS
FURTHER EAST BY THURSDAY NIGHT.

&&

.NEAR TERM /THROUGH TONIGHT/...
1030 AM UPDATE...
SEVERAL UPDATES TO ONGOING FORECAST. UPDATED/TIGHTENED UP POPS TO
REFLECT PERSISTENT BAND OF SHOWERS ALONG AND JUST NORTH OF THE I64
CORRIDOR...WHICH APPEARS TO BE ASSOC WITH THE ELEVATED FRONT. EVEN
HAVE HAD A COUPLE OF LIGHTNING STRIKES NORTHWEST OF CRW IN THE
PAST 30-45 MINS...SO ADDED IN SLIGHT THUNDER AS WELL FROM THERE
AND POINTS SOUTH. THAT SAME STORM CURRENTLY OVER SOUTHERN JACKSON
COUNTY BEARS WATCHING...AS IT IS MAKING A BEELINE STRAIGHT FOR
WEST-CENTRAL BRAXTON COUNTY WHICH RECEIVED A RADAR-ESTIMATED 2.50IN+
OF RAIN EARLIER THIS MORNING. FINALLY...UPDATED THE HOURLY TEMP
CURVE TODAY WITH CONTINUED CLOUD COVER AND WEAK COLD
ADVECTION...EXPECT TEMPS TO REMAIN STEADY OR EVEN DROP A DEGREE OR
TWO BEFORE REBOUNDING MID/LATE AFTERNOON.

PREVIOUS DISCUSSION...
CERTAINLY AN UNUSUAL PATTERN FOR LATE JULY. HAVE SURFACE FRONT
ABOUT ON TIME WITH OUR THINKING 24 HOURS AGO. AROUND
08Z...ANALYZING THE FRONT SOUTH OF EKN TO JUST S OF CRW TO NEAR
JKL AT 08Z. YET...EVEN SOUTH OF THE FRONT...KFCX RADAR HAS A
NORTHWEST FLOW AT 925 MB.

LOCAL DOWNPOURS HAVE BEEN OCCURRING OVERNIGHT.  RAIN RATES
OF .75 IN 15 MINUTES HAVE BEEN MEASURED.  THE HIGHEST 3 HOUR TOTAL
OVERNIGHT...THRU 08Z WAS LATE WEDNESDAY EVENING WAS AN ESTIMATED 3
INCHES ALONG THE BOONE/RALEIGH COUNTY LINE.  SO FAR...NO SIGNIFICANT
FLOODING REPORTS HAVE BEEN RECEIVED.  ALSO CONCERNED ABOUT THE
REPETITIVE CELLS THIS PREDAWN THURSDAY IN CLAY COUNTY.

THE SECONDARY RAIN AREA BETWEEN HTS AND CVG SEEMS TO BE IN THE
850 MB THERMAL GRADIENT NORTH OF THE FRONT.  FIGURING IT WILL MOVE
EAST INTO CENTRAL WEST VIRGINIA THIS MORNING.  ALSO FIGURING WITH
PW(S) LOWERING...THAT RAIN RATES WILL DECREASE THIS MORNING.  IF
NOT...FLASH FLOOD WATCHES OR WARNING MAY BE NEEDED.

WITH 925 MB FLOW TURNING NE...STILL HAVE THE DRIER AIR HAVING A
TOUGH TIME PENETRATING INTO THE HEART OF CENTRAL AND SOUTHERN WEST
VIRGINIA...BUT SHOULD ARRIVE LATE TODAY.  I CAN PICTURE THE SOUTHERN
PLATEAU OF SOUTHERN WV GETTING INTO LOW CLOUDS WITH A DIURNAL
TEMPERATURE SPREAD OF 5 DEGREES.  SO NOT YOUR "CHAMBER OF COMMERCE
DAY" PICTURED FOR PLACES LIKE BECKLEY.

WENT WITH SOME FOG OR LOW STRATUS 06Z TO 12Z FRIDAY IN THE WEST
VIRGINIA VALLEYS.  DID NOT GO QUITE AS CHILLY FROM THE ELK RIVER
VALLEY ON SOUTH INTO THE SOUTHERN COAL FIELDS FOR MINIMUM
TEMPERATURES TONIGHT...THIS INCLUDES KANAWHA VALLEY AROUND CRW.
FIGURING ON THAT FOG AND WET TERRAIN HOLDING READINGS UP.

&&

.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
SURFACE HIGH PRESSURE WILL BRING PLEASANT WEATHER TO END THE WORK
WEEK. SEVERAL 500MB RIPPLES ARE PROGGED TO CROSS THE FORECAST AREA
SATURDAY INTO SATURDAY NIGHT. IT MAY TAKE A WHILE FOR THE ATMOSPHERE
TO MOISTEN BACK UP AS THE HIGH DEPARTS...BUT WITH THE UPPER LEVEL
DISTURBANCES DO HAVE CHANCE POPS ACROSS MOST OF THE FORECAST AREA
SATURDAY AFTERNOON AND SATURDAY NIGHT. MINIMAL CHANGES MADE TO HIGHS
AND LOWS BY BLENDING IN CONSENSUS GUIDANCE.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
TWO DISTINCTIVE SHORT WAVE EVIDENT IN H5 CHARTS WILL CROSS THE AREA
SATURDAY AND SUNDAY...KEEPING CHANCES FOR SHOWERS AND STORMS AT
LEAST PARTS OF UP COMING WEEKEND. THE FIRST COMES ALONG THE BACK
SIDE OF AN UPPER TROUGH AND THE SECOND ONE IN A ZONAL FLOW ALOFT.

MODELS QPF FIELDS KEEP SATURDAY RELATIVELY DRY...AND TARGET MORE THE
SYSTEM ON SUNDAY WITH A VORTICITY MAX IN THE NORTHERN STREAM PASSING
OVER AN OLD FRONTAL BOUNDARY OVER OUR CWA. THE A COLD FRONT
APPROACHES THE AREA FROM THE NORTHWEST EARLY MONDAY
MORNING...KEEPING THE POSSIBILITY FOR MORE PCPN.
THEREFORE...INCREASED CHANCE POPS SATURDAY NIGHT INTO LIKELIES FOR
SUNDAY...AS EXPECTED CONVECTION MOVES EAST SUNDAY NIGHT.

HIGH PRESSURE BEHIND THE COLD FRONT TAKES CONTROL LATER MONDAY
THROUGH THE MIDDLE OF NEXT WEEK WITH NEAR NORMAL TEMPERATURES.

USED A BLEND OF DIFFERENT GUIDANCE...WARMER SATURDAY NIGHT INTO
SUNDAY PER DEEP SOUTHWEST FLOW AND ASSOCIATED WARM ADVECTION...WITH
A COOLER TREND AFTER THE WEEKENDS FRONT.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
157 PM EDT WED JUL 23 2014

.SYNOPSIS...
COLD FRONT SLOWLY SINKS SOUTH...INCREASING SHOWERS AND STORMS
THROUGH TONIGHT. SHORTWAVE PASSES OVER FRONT EARLY THURSDAY.
DRIER AIR ARRIVES ON THURSDAY. BRIEF HIGH PRESSURE FRIDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
130 PM UPDATE...
STILL HAVE SCATTERED SHOWERS WITH SOME THUNDER OVER THE FORECAST
AREA BUT HAVE LOWERED POPS ONCE AGAIN OVER THE NORTHWEST TO DELAY
ONSET OF HIGHEST POPS.

1030 AM UPDATE...
ADJUSTMENTS MADE TO POPS AND SKY TO REFLECT CURRENT CONDITIONS AND
TRENDS. INCREASED POPS/SKY JUST A BIT MAINLY SOUTHEAST OF THE I79
CORRIDOR AS A COUPLE OF THIN PREFRONTAL BANDS OF SHOWERS AND
EMBEDDED THUNDER MOVE SLOWLY EAST/SOUTHEAST. LOWERED POPS THROUGH
THE MORNING HOURS OVER THE NORTHWEST HALF OF THE AREA WITH CURRENT
VIS SHOWING A GOOD AMOUNT OF SUNSHINE OVER THAT AREA. STILL EXPECT
A QUICK RAMP-UP OF CLOUDS AND PRECIP BY THE EARLY/MID AFTERNOON HOURS.

PREVIOUS DISCUSSION...
CERTAINLY WAS A WARM AND MUGGY OVERNIGHT AND EARLY MORNING...WITH
DEW POINTS ON EITHER SIDE OF 70 DEGREES.

HAVE LOW CONFIDENCE ON EXACTLY HOW THE AREAS OF CONVECTION WILL
EVOLVE TODAY INTO TONIGHT.  YET...TRIED TO KEEP THE HIGHER POPS...IN
THE LIKELY RANGE...OUT AHEAD OF THE FRONT FOR TODAY...THEN LINGERED
THOSE HIGHER POPS A BIT LONGER IN OUR SOUTHERN COUNTIES LATE
TONIGHT...AS THE MID LEVEL 500 MB TROF AXIS ACTS ON THE BAROCLINIC
ZONE.

EVEN AS DAWN APPROACHES...COULD NOT RULE OUT SHOWERS FORMING THIS
MORNING...PATCHES OF CLOUDS HAVE BEEN FORMING PAST FEW HOURS.
PROBABLY RELATED TO THE INCREASE LOW LEVEL FLOW...COULD NOT
LOCATE/FIND ANY DISTURBANCES.  SO WE STILL KEPT THE FOG AT A MINIMUM
FOR DAWN.  MOSTLY IN THE DEEPER MOUNTAIN VALLEYS.

SOME THUNDERSTORMS COULD FORM DURING THE DAYTIME INSTABILITY FURTHER
SOUTH...AWAY FROM THE APPROACHING FRONT...OVER SOUTHERN COUNTIES.

EQUILIBRIUM LEVELS TRY TO REACH 35 TO 40 THSD...ESPECIALLY ACROSS
SOUTHERN LOWLANDS THIS AFTERNOON.  MID LEVEL WINDS RATHER WEAK.
YET...COULD NOT RULE OUT A PULSE STORM REACHING SEVERE LIMITS...BUT
OVERALL THE THREAT FOR A LOT OF DAMAGING WIND GUSTS OR LARGE STILL
APPEARS TO BE RATHER LOW.  OF COURSE THE USUAL LIGHTNING AND
DOWNPOURS STILL DESERVES RESPECT.

HAVE THE FRONT ITSELF REACHING INTO THE MID OHIO VALLEY NEAR
MARIETTA AND PARKERSBURG AROUND 00Z THIS EVENING...THEN REACHING OUT
SOUTHERN MOUNTAINS AROUND BKW ABOUT 09Z THURSDAY.  YET...WINDS AT
MOST LEVELS BEGIN TO VEER BEFORE THE SURFACE FRONT PASSES.

HAVE THUNDER CHANCES DECREASING N/S OVERNIGHT...EVEN THOUGH POPS
REMAIN RELATIVELY HIGH IN THE SOUTH DURING THE LATE NIGHT HOURS.

LOWERED MAXIMUM TEMPERATURES...ESPECIALLY IN THE NORTH WHERE CLOUDS
AND HIGHER POPS EXPECTED SOONER.

HAVE THE NORTH WIND DRIVING SOUTH IN SOUTHEAST OHIO TONIGHT...WITH
SOME CLEARING THERE LATE TONIGHT...AND LOWERED MINIMUM TEMPERATURES
A BIT ESPECIALLY FROM HOCKING VALLEY NORTH.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
WHILE COLD FRONT WILL BE THROUGH FORECAST AREA TO START THE SHORT

TROUGH APPROACHES. WILL BE DRYING OUT FOR FRIDAY AS SURFACE HIGH
PRESSURE CROSSES. ALL MODELS SHOW A FAIRLY WEAK 500MB SHORTWAVE
TROUGH SLIDING ACROSS IN NW FLOW FRIDAY NIGHT INTO SATURDAY.
INCREASED POPS FRIDAY NIGHT ANTICIPATING DECAYING CONVECTIVE COMPLEX
APPROACHING FROM THE WEST ON A STRONG WAA AT 850MB. ALSO INCREASED
POPS ON SATURDAY WITH THE ACTUAL UPPER LEVEL RIPPLE.

BEHIND THE COLD FRONT...AND WITH LINGERING CLOUDS...EXPECT HIGH
TEMPS ON THURSDAY TO STAY BELOW 80. ADDED A COUPLE DEGREES TO THAT
FOR FRIDAY WITH MORE SUNSHINE...AND THEN ANOTHER COUPLE DEGREES
SATURDAY AS THE WINDS TURN MORE SOUTHERLY. EXPECTING A COOLER NIGHT
THURSDAY NIGHT WITH LOTS OF READINGS IN THE 50S. CLOUDS SHOULD KEEP

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
1220 PM EDT WED JUL 23 2014

.SYNOPSIS...
COLD FRONT SLOWLY SINKS SOUTH...INCREASING SHOWERS AND STORMS
THROUGH TONIGHT. SHORTWAVE PASSES OVER FRONT EARLY THURSDAY.
DRIER AIR ARRIVES ON THURSDAY. BRIEF HIGH PRESSURE FRIDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
1030 AM UPDATE...
ADJUSTMENTS MADE TO POPS AND SKY TO REFLECT CURRENT CONDITIONS AND
TRENDS. INCREASED POPS/SKY JUST A BIT MAINLY SOUTHEAST OF THE I79
CORRIDOR AS A COUPLE OF THIN PREFRONTAL BANDS OF SHOWERS AND
EMBEDDED THUNDER MOVE SLOWLY EAST/SOUTHEAST. LOWERED POPS THROUGH
THE MORNING HOURS OVER THE NORTHWEST HALF OF THE AREA WITH CURRENT
VIS SHOWING A GOOD AMOUNT OF SUNSHINE OVER THAT AREA. STILL EXPECT
A QUICK RAMP-UP OF CLOUDS AND PRECIP BY THE EARLY/MID AFTERNOON HOURS.

PREVIOUS DISCUSSION...
CERTAINLY WAS A WARM AND MUGGY OVERNIGHT AND EARLY MORNING...WITH
DEW POINTS ON EITHER SIDE OF 70 DEGREES.

HAVE LOW CONFIDENCE ON EXACTLY HOW THE AREAS OF CONVECTION WILL
EVOLVE TODAY INTO TONIGHT.  YET...TRIED TO KEEP THE HIGHER POPS...IN
THE LIKELY RANGE...OUT AHEAD OF THE FRONT FOR TODAY...THEN LINGERED
THOSE HIGHER POPS A BIT LONGER IN OUR SOUTHERN COUNTIES LATE
TONIGHT...AS THE MID LEVEL 500 MB TROF AXIS ACTS ON THE BAROCLINIC
ZONE.

EVEN AS DAWN APPROACHES...COULD NOT RULE OUT SHOWERS FORMING THIS
MORNING...PATCHES OF CLOUDS HAVE BEEN FORMING PAST FEW HOURS.
PROBABLY RELATED TO THE INCREASE LOW LEVEL FLOW...COULD NOT
LOCATE/FIND ANY DISTURBANCES.  SO WE STILL KEPT THE FOG AT A MINIMUM
FOR DAWN.  MOSTLY IN THE DEEPER MOUNTAIN VALLEYS.

SOME THUNDERSTORMS COULD FORM DURING THE DAYTIME INSTABILITY FURTHER
SOUTH...AWAY FROM THE APPROACHING FRONT...OVER SOUTHERN COUNTIES.

EQUILIBRIUM LEVELS TRY TO REACH 35 TO 40 THSD...ESPECIALLY ACROSS
SOUTHERN LOWLANDS THIS AFTERNOON.  MID LEVEL WINDS RATHER WEAK.
YET...COULD NOT RULE OUT A PULSE STORM REACHING SEVERE LIMITS...BUT
OVERALL THE THREAT FOR A LOT OF DAMAGING WIND GUSTS OR LARGE STILL
APPEARS TO BE RATHER LOW.  OF COURSE THE USUAL LIGHTNING AND
DOWNPOURS STILL DESERVES RESPECT.

HAVE THE FRONT ITSELF REACHING INTO THE MID OHIO VALLEY NEAR
MARIETTA AND PARKERSBURG AROUND 00Z THIS EVENING...THEN REACHING OUT
SOUTHERN MOUNTAINS AROUND BKW ABOUT 09Z THURSDAY.  YET...WINDS AT
MOST LEVELS BEGIN TO VEER BEFORE THE SURFACE FRONT PASSES.

HAVE THUNDER CHANCES DECREASING N/S OVERNIGHT...EVEN THOUGH POPS
REMAIN RELATIVELY HIGH IN THE SOUTH DURING THE LATE NIGHT HOURS.

LOWERED MAXIMUM TEMPERATURES...ESPECIALLY IN THE NORTH WHERE CLOUDS
AND HIGHER POPS EXPECTED SOONER.

HAVE THE NORTH WIND DRIVING SOUTH IN SOUTHEAST OHIO TONIGHT...WITH
SOME CLEARING THERE LATE TONIGHT...AND LOWERED MINIMUM TEMPERATURES
A BIT ESPECIALLY FROM HOCKING VALLEY NORTH.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
WHILE COLD FRONT WILL BE THROUGH FORECAST AREA TO START THE SHORT
TERM...POST FRONTAL PRECIP WILL STILL BE LINGERING AS UPPER LEVEL
TROUGH APPROACHES. WILL BE DRYING OUT FOR FRIDAY AS SURFACE HIGH
PRESSURE CROSSES. ALL MODELS SHOW A FAIRLY WEAK 500MB SHORTWAVE
TROUGH SLIDING ACROSS IN NW FLOW FRIDAY NIGHT INTO SATURDAY.
INCREASED POPS FRIDAY NIGHT ANTICIPATING DECAYING CONVECTIVE COMPLEX
APPROACHING FROM THE WEST ON A STRONG WAA AT 850MB. ALSO INCREASED
POPS ON SATURDAY WITH THE ACTUAL UPPER LEVEL RIPPLE.

BEHIND THE COLD FRONT...AND WITH LINGERING CLOUDS...EXPECT HIGH
TEMPS ON THURSDAY TO STAY BELOW 80. ADDED A COUPLE DEGREES TO THAT
FOR FRIDAY WITH MORE SUNSHINE...AND THEN ANOTHER COUPLE DEGREES
SATURDAY AS THE WINDS TURN MORE SOUTHERLY. EXPECTING A COOLER NIGHT
THURSDAY NIGHT WITH LOTS OF READINGS IN THE 50S. CLOUDS SHOULD KEEP
FRIDAY NIGHT JUST A TOUCH WARMER.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
TWO DISTINCTIVE SHORT WAVE EVIDENT IN H5 CHARTS WILL CROSS THE AREA
SATURDAY AND SUNDAY...KEEPING CHANCES FOR SHOWERS AND STORMS AT
LEAST PARTS OF UP COMING WEEKEND. THE FIRST COMES ALONG THE BACK
SIDE OF AN UPPER TROUGH AND THE SECOND ONE IN A ZONAL FLOW ALOFT.

MODELS QPF FIELDS KEEP SATURDAY RELATIVELY DRY...AND TARGET MORE THE
SYSTEM ON SUNDAY WITH A VORTICITY MAX IN THE NORTHERN STREAM PASSING
OVER AN OLD FRONTAL BOUNDARY OVER OUR CWA. THE A COLD FRONT
APPROACHES THE AREA FROM THE NORTHWEST EARLY MONDAY
MORNING...KEEPING THE POSSIBILITY FOR MORE PCPN.
THEREFORE...INCREASED CHANCE POPS SATURDAY NIGHT INTO LIKELIES FOR
SUNDAY...AS EXPECTED CONVECTION MOVES EAST SUNDAY NIGHT.

HIGH PRESSURE BEHIND THE COLD FRONT TAKES CONTROL LATER MONDAY
THROUGH THE MIDDLE OF NEXT WEEK WITH NEAR NORMAL TEMPERATURES.

USED A BLEND OF DIFFERENT GUIDANCE...WARMER SATURDAY NIGHT INTO
SUNDAY PER DEEP SOUTHWEST FLOW AND ASSOCIATED WARM ADVECTION...WITH
A COOLER TREND AFTER THE WEEKENDS FRONT.

&&

.AVIATION /16Z WEDNESDAY THROUGH SUNDAY/...
NEAR TERM MODELS CONTINUE TO FORM SPOTTY SHOWERS AND A FEW
THUNDERSTORMS THIS MORNING. CELLS DID FORM PKB TO CKB VCNTY AROUND
10Z. MAY BE RELATED TO THE INCREASING LOW LEVEL FLOW...AFTER 2
DAYS OF DEAD FLOW.

OUTFLOW FROMM OLDER CONVECTION SINKING SOUTH THROUGH OHIO.  INCREASED
POPS SOONER IN SOUTHEAST OHIO THIS MORNING.

STILL TIMING THE FRONT TO REACH THE MID OHIO VALLEY AROUND PKB ABOUT
00Z...THEN EKN TO CRW AROUND 04Z...AND THE SOUTHERN MOUNTAINS AROUND
BKW BEFORE DAWN...AROUND 08Z.

TIMING THE VARIOUS ROUNDS OF CONVECTION TODAY INTO TONIGHT...HAS
CONFIDENCE LEVEL LOWERED TO LOW.  THERE COULD EVEN BE SOME SEPARATE
CONVECTION FORMING OVER THE SOUTHERN COUNTIES...AWAY FROM THE
FRONT...DUE TO THE DAYTIME INSTABILITY.   HAVE THE LIKELY
POPS...MOST COVERAGE...AHEAD OF THE FRONT ITSELF. THOSE LIKELY POPS
REACHING INTO SOUTHEAST OHIO AFTER 15Z...AND INTO CENTRAL WEST
VIRGINIA TOWARD 18Z...THEN HTS TO CRW CORRIDOR 20/21Z...AND BKW
AFTER 00Z.  AGAIN THAT IS FOR THE MOST COVERAGE.

CEILINGS 2 TO 3 THSD FT AND VSBY AOB 3 MILES IN ANY PREFRONTAL
CONVECTION.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
627 AM EDT WED JUL 23 2014

.SYNOPSIS...
COLD FRONT SINKS SOUTH TODAY...INCREASING SHOWERS AND STORMS. FRONT
PASSES TONIGHT...WITH WAVE ALONG FRONT LATE TONIGHT AND EARLY
THURSDAY. DRIER AIR ARRIVES ON THURSDAY. BRIEF HIGH PRESSURE FRIDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
CERTAINLY WAS A WARM AND MUGGY OVERNIGHT AND EARLY MORNING...WITH
DEW POINTS ON EITHER SIDE OF 70 DEGREES.

HAVE LOW CONFIDENCE ON EXACTLY HOW THE AREAS OF CONVECTION WILL
EVOLVE TODAY INTO TONIGHT.  YET...TRIED TO KEEP THE HIGHER POPS...IN
THE LIKELY RANGE...OUT AHEAD OF THE FRONT FOR TODAY...THEN LINGERED
THOSE HIGHER POPS A BIT LONGER IN OUR SOUTHERN COUNTIES LATE
TONIGHT...AS THE MID LEVEL 500 MB TROF AXIS ACTS ON THE BAROCLINIC
ZONE.

EVEN AS DAWN APPROACHES...COULD NOT RULE OUT SHOWERS FORMING THIS
MORNING...PATCHES OF CLOUDS HAVE BEEN FORMING PAST FEW HOURS.
PROBABLY RELATED TO THE INCREASE LOW LEVEL FLOW...COULD NOT
LOCATE/FIND ANY DISTURBANCES.  SO WE STILL KEPT THE FOG AT A MINIMUM
FOR DAWN.  MOSTLY IN THE DEEPER MOUNTAIN VALLEYS.

SOME THUNDERSTORMS COULD FORM DURING THE DAYTIME INSTABILITY FURTHER
SOUTH...AWAY FROM THE APPROACHING FRONT...OVER SOUTHERN COUNTIES.

EQUILIBRIUM LEVELS TRY TO REACH 35 TO 40 THSD...ESPECIALLY ACROSS
SOUTHERN LOWLANDS THIS AFTERNOON.  MID LEVEL WINDS RATHER WEAK.
YET...COULD NOT RULE OUT A PULSE STORM REACHING SEVERE LIMITS...BUT
OVERALL THE THREAT FOR A LOT OF DAMAGING WIND GUSTS OR LARGE STILL
APPEARS TO BE RATHER LOW.  OF COURSE THE USUAL LIGHTNING AND
DOWNPOURS STILL DESERVES RESPECT.

HAVE THE FRONT ITSELF REACHING INTO THE MID OHIO VALLEY NEAR
MARIETTA AND PARKERSBURG AROUND 00Z THIS EVENING...THEN REACHING OUT
SOUTHERN MOUNTAINS AROUND BKW ABOUT 09Z THURSDAY.  YET...WINDS AT
MOST LEVELS BEGIN TO VEER BEFORE THE SURFACE FRONT PASSES.

HAVE THUNDER CHANCES DECREASING N/S OVERNIGHT...EVEN THOUGH POPS
REMAIN RELATIVELY HIGH IN THE SOUTH DURING THE LATE NIGHT HOURS.

LOWERED MAXIMUM TEMPERATURES...ESPECIALLY IN THE NORTH WHERE CLOUDS
AND HIGHER POPS EXPECTED SOONER.

HAVE THE NORTH WIND DRIVING SOUTH IN SOUTHEAST OHIO TONIGHT...WITH
SOME CLEARING THERE LATE TONIGHT...AND LOWERED MINIMUM TEMPERATURES
A BIT ESPECIALLY FROM HOCKING VALLEY NORTH.

&&

.SHORT TERM /THURSDAY THROUGH SATURDAY/...
WHILE COLD FRONT WILL BE THROUGH FORECAST AREA TO START THE SHORT
TERM...POST FRONTAL PRECIP WILL STILL BE LINGERING AS UPPER LEVEL
TROUGH APPROACHES. WILL BE DRYING OUT FOR FRIDAY AS SURFACE HIGH
PRESSURE CROSSES. ALL MODELS SHOW A FAIRLY WEAK 500MB SHORTWAVE
TROUGH SLIDING ACROSS IN NW FLOW FRIDAY NIGHT INTO SATURDAY.
INCREASED POPS FRIDAY NIGHT ANTICIPATING DECAYING CONVECTIVE COMPLEX
APPROACHING FROM THE WEST ON A STRONG WAA AT 850MB. ALSO INCREASED
POPS ON SATURDAY WITH THE ACTUAL UPPER LEVEL RIPPLE.

BEHIND THE COLD FRONT...AND WITH LINGERING CLOUDS...EXPECT HIGH
TEMPS ON THURSDAY TO STAY BELOW 80. ADDED A COUPLE DEGREES TO THAT
FOR FRIDAY WITH MORE SUNSHINE...AND THEN ANOTHER COUPLE DEGREES
SATURDAY AS THE WINDS TURN MORE SOUTHERLY. EXPECTING A COOLER NIGHT
THURSDAY NIGHT WITH LOTS OF READINGS IN THE 50S. CLOUDS SHOULD KEEP
FRIDAY NIGHT JUST A TOUCH WARMER.

&&

.LONG TERM /SATURDAY NIGHT THROUGH TUESDAY/...
USED HPC GUIDANCE FOR MOST OF THE WEATHER ELEMENTS WITH A FEW
MINOR TWEAKS THROUGH THE PERIOD.

ALTHOUGH NORTHWEST FLOW AT H5 WEAKENS SOME 5H...A SHORTWAVE IS
EXPECTED BY MODELS TO SLIDE ACROSS OUR AREA LATER SATURDAY INTO
SUNDAY. THIS FEATURE COULD BRING CHANCES FOR RAIN SHOWERS OR STORMS
BY THE SECOND HALF OF THE WEEKEND.

A LARGE OCCLUDING SYSTEM MEANDERS SOUTH THROUGH MONDAY...AS CUT-
OFF LOW DEVELOPS OVER THE GREAT LAKES. BOTH ECMWF AND GFS IN
FAIRLY GOOD AGREEMENT IN PLAYING OUT THIS SCENARIO LATE IN THE
PERIOD FOR A GENERAL UPSWING IN PRECIPITATION CHANCES BY EARLY
MONDAY.

WEAK AND FRESH NORTHERLY FLOW PREVAILS BEHIND THE FRONT TUESDAY
WITH PLEASANT TEMPERATURES EXPECTED.

&&

.AVIATION /12Z WEDNESDAY THROUGH SUNDAY/...
NEAR TERM MODELS CONTINUE TO FORM SPOTTY SHOWERS AND A FEW
THUNDERSTORMS THIS MORNING.  CELLS DID FORM PKB TO CKB VCNTY AROUND
10Z.  MAY BE RELATED TO THE INCREASING LOW LEVEL FLOW...AFTER 2 DAYS
OF DEAD FLOW.

OUTFLOW FROMM OLDER CONVECTION SINKING SOUTH THROUGH OHIO.  INCREASED
POPS SOONER IN SOUTHEAST OHIO THIS MORNING.

STILL TIMING THE FRONT TO REACH THE MID OHIO VALLEY AROUND PKB ABOUT
00Z...THEN EKN TO CRW AROUND 04Z...AND THE SOUTHERN MOUNTAINS AROUND
BKW BEFORE DAWN...AROUND 08Z.

TIMING THE VARIOUS ROUNDS OF CONVECTION TODAY INTO TONIGHT...HAS
CONFIDENCE LEVEL LOWERED TO LOW.  THERE COULD EVEN BE SOME SEPARATE
CONVECTION FORMING OVER THE SOUTHERN COUNTIES...AWAY FROM THE
FRONT...DUE TO THE DAYTIME INSTABILITY.   HAVE THE LIKELY
POPS...MOST COVERAGE...AHEAD OF THE FRONT ITSELF. THOSE LIKELY POPS
REACHING INTO SOUTHEAST OHIO AFTER 15Z...AND INTO CENTRAL WEST
VIRGINIA TOWARD 18Z...THEN HTS TO CRW CORRIDOR 20/21Z...AND BKW
AFTER 00Z.  AGAIN THAT IS FOR THE MOST COVERAGE.

CEILINGS 2 TO 3 THSD FT AND VSBY AOB 3 MILES IN ANY PREFRONTAL
CONVECTION.

IN THE WAKE OF THE FRONT...HAVE SHOWERS LINGERING ACROSS SOUTHERN
AND MOUNTAIN COUNTIES AT 06Z THURSDAY...WITH WAVE ACTION ALONG THE
FRONT.  SO HOLDING LIKELY POPS THROUGH THE NIGHT...BUT TRANSITIONING
TO MOSTLY SHOWERS...RATHER THAN THUNDERSTORMS.

CEILINGS LOWERING 1 TO 2 THSD FT AND VSBY AROUND 3 MILES IN POST
FRONTAL SHOWERS.  CEILINGS OVER HIGH MOUNTAINS LIKELY TO DROP BELOW
1 THSD FT AND VSBY BLO 3 MILES.

MEANWHILE...DRIER AIR MOVING SOUTH INTO SOUTHEAST OHIO AND TOWARD

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
405 AM EDT WED JUL 23 2014

.SYNOPSIS...
COLD FRONT SINKS SOUTH TODAY...INCREASING SHOWERS AND STORMS. FRONT
PASSES TONIGHT...WITH WAVE ALONG FRONT LATE TONIGHT AND EARLY
THURSDAY. DRIER AIR ARRIVES ON THURSDAY. BRIEF HIGH PRESSURE FRIDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
CERTAINLY WAS A WARM AND MUGGY OVERNIGHT AND EARLY MORNING...WITH
DEW POINTS ON EITHER SIDE OF 70 DEGREES.

HAVE LOW CONFIDENCE ON EXACTLY HOW THE AREAS OF CONVECTION WILL
EVOLVE TODAY INTO TONIGHT.  YET...TRIED TO KEEP THE HIGHER POPS...IN
THE LIKELY RANGE...OUT AHEAD OF THE FRONT FOR TODAY...THEN LINGERED
THOSE HIGHER POPS A BIT LONGER IN OUR SOUTHERN COUNTIES LATE
TONIGHT...AS THE MID LEVEL 500 MB TROF AXIS ACTS ON THE BAROCLINIC
ZONE.

EVEN AS DAWN APPROACHES...COULD NOT RULE OUT A LIGHT SHOWER FORMING
THIS MORNING...PATCHES OF CLOUDS HAVE BEEN FORMING PAST FEW HOURS.
PROBABLY RELATED TO THE INCREASE LOW LEVEL FLOW...COULD NOT
LOCATE/FIND ANY DISTURBANCES.  SO WE STILL KEPT THE FOG AT A MINIMUM
FOR DAWN.  MOSTLY IN THE DEEPER MOUNTAIN VALLEYS.

SOME THUNDERSTORMS COULD FORM DURING THE DAYTIME INSTABILITY FURTHER
SOUTH...AWAY FROM THE APPROACHING FRONT...OVER SOUTHERN COUNTIES.

EQUILIBRIUM LEVELS TRY TO REACH 35 TO 40 THSD...ESPECIALLY ACROSS
SOUTHERN LOWLANDS THIS AFTERNOON.  MID LEVEL WINDS RATHER WEAK.
YET...COULD NOT RULE OUT A PULSE STORM REACHING SEVERE LIMITS...BUT
OVERALL THE THREAT FOR A LOT OF DAMAGING WIND GUSTS OR LARGE STILL
APPEARS TO BE RATHER LOW.  OF COURSE THE USUAL LIGHTNING AND
DOWNPOURS STILL DESERVES RESPECT.

HAVE THE FRONT ITSELF REACHING INTO THE MID OHIO VALLEY NEAR
MARIETTA AND PARKERSBURG AROUND 00Z THIS EVENING...THEN REACHING OUT
SOUTHERN MOUNTAINS AROUND BKW ABOUT 09Z THURSDAY.  YET...WINDS AT
MOST LEVELS BEGIN TO VEER BEFORE THE SURFACE FRONT PASSES.

HAVE THUNDER CHANCES DECREASING N/S OVERNIGHT...EVEN THOUGH POPS
REMAIN RELATIVELY HIGH IN THE SOUTH DURING THE LATE NIGHT HOURS.

LOWERED MAXIMUM TEMPERATURES...ESPECIALLY IN THE NORTH WHERE CLOUDS
AND HIGHER POPS EXPECTED SOONER.

HAVE THE NORTH WIND DRIVING SOUTH IN SOUTHEAST OHIO TONIGHT...WITH
SOME CLEARING THERE LATE TONIGHT...AND LOWERED MINIMUM TEMPERATURES
A BIT ESPECIALLY FROM HOCKING VALLEY NORTH.

&&

.SHORT TERM /THURSDAY THROUGH SATURDAY/...
WHILE COLD FRONT WILL BE THROUGH FORECAST AREA TO START THE SHORT
TERM...POST FRONTAL PRECIP WILL STILL BE LINGERING AS UPPER LEVEL
TROUGH APPROACHES. WILL BE DRYING OUT FOR FRIDAY AS SURFACE HIGH
PRESSURE CROSSES. ALL MODELS SHOW A FAIRLY WEAK 500MB SHORTWAVE
TROUGH SLIDING ACROSS IN NW FLOW FRIDAY NIGHT INTO SATURDAY.
INCREASED POPS FRIDAY NIGHT ANTICIPATING DECAYING CONVECTIVE COMPLEX
APPROACHING FROM THE WEST ON A STRONG WAA AT 850MB. ALSO INCREASED
POPS ON SATURDAY WITH THE ACTUAL UPPER LEVEL RIPPLE.

BEHIND THE COLD FRONT...AND WITH LINGERING CLOUDS...EXPECT HIGH
TEMPS ON THURSDAY TO STAY BELOW 80. ADDED A COUPLE DEGREES TO THAT
FOR FRIDAY WITH MORE SUNSHINE...AND THEN ANOTHER COUPLE DEGREES
SATURDAY AS THE WINDS TURN MORE SOUTHERLY. EXPECTING A COOLER NIGHT
THURSDAY NIGHT WITH LOTS OF READINGS IN THE 50S. CLOUDS SHOULD KEEP
FRIDAY NIGHT JUST A TOUCH WARMER.

&&

.LONG TERM /SATURDAY NIGHT THROUGH TUESDAY/...
USED HPC GUIDANCE FOR MOST OF THE WEATHER ELEMENTS WITH A FEW
MINOR TWEAKS THROUGH THE PERIOD.

ALTHOUGH NORTHWEST FLOW AT H5 WEAKENS SOME 5H...A SHORTWAVE IS
EXPECTED BY MODELS TO SLIDE ACROSS OUR AREA LATER SATURDAY INTO
SUNDAY. THIS FEATURE COULD BRING CHANCES FOR RAIN SHOWERS OR STORMS
BY THE SECOND HALF OF THE WEEKEND.

A LARGE OCCLUDING SYSTEM MEANDERS SOUTH THROUGH MONDAY...AS CUT-
OFF LOW DEVELOPS OVER THE GREAT LAKES. BOTH ECMWF AND GFS IN
FAIRLY GOOD AGREEMENT IN PLAYING OUT THIS SCENARIO LATE IN THE
PERIOD FOR A GENERAL UPSWING IN PRECIPITATION CHANCES BY EARLY
MONDAY.

WEAK AND FRESH NORTHERLY FLOW PREVAILS BEHIND THE FRONT TUESDAY
WITH PLEASANT TEMPERATURES EXPECTED.

&&

.AVIATION /08Z WEDNESDAY THROUGH SUNDAY/...
VERY MUGGY AIR WITH DEW POINTS ON EITHER SIDE OF 70 DEGREES.  STILL
NOT HITTING THE FOG HARD FOR THE PREDAWN AND DAWN HOURS.  SOME OF
THE DEEPER MOUNTAIN VALLEYS...LIKE ELKINS...MAY VARY BETWEEN IFR AND
MVFR IN FOG. OTHERWISE SOME 5 TO 6 MILES IN HAZE POSSIBLE INTO
MID MORNING...SAY 14Z.

NEAR TERM MODELS CONTINUE TO FORM SOME PREDAWN SHOWERS IN WV.  MAY
BE RELATED TO THE INCREASING LOW LEVEL FLOW...AFTER 2 DAYS OF DEAD
FLOW.  WILL INSERT A SLIGHT CHANCE POP FOR EARLY THIS MORNING...BUT
NOT INCLUDE IN ANY POINT TAF SITES AT THE 06Z TAF ISSUANCE TIME.

TIMING THE FRONT TO REACH THE MID OHIO VALLEY AROUND PKB ABOUT
00Z...THEN EKN TO CRW AROUND 04Z...AND THE SOUTHERN MOUNTAINS
AROUND BKW BEFORE DAWN...AROUND 08Z.

TIMING THE VARIOUS ROUNDS OF CONVECTION HAS CONFIDENCE LEVEL LOWERED
TO LOW.  THERE COULD EVEN BE SOME SEPARATE CONVECTION FORMING OVER
THE SOUTHERN COUNTIES...AWAY FROM THE FRONT...DUE TO THE DAYTIME
INSTABILITY.   HAVE THE LIKELY POPS...MOST COVERAGE...AHEAD OF THE
FRONT ITSELF. THOSE LIKELY POPS REACHING INTO SOUTHEAST OHIO AFTER
15Z...AND INTO CENTRAL WEST VIRGINIA TOWARD 18Z...THEN HTS TO CRW
CORRIDOR 20/21Z...AND BKW AFTER 00Z.  AGAIN THAT IS FOR THE MOST
COVERAGE.

CEILINGS 2 TO 3 THSD FT AND VSBY NEAR 3 MILES IN ANY PREFRONTAL
CONVECTION.

IN THE WAKE OF THE FRONT...HAVE SHOWERS LINGERING ACROSS SOUTHERN
AND MOUNTAIN COUNTIES AT 06Z THURSDAY...WITH WAVE ACTION ALONG THE
FRONT.  SO HOLDING LIKELY POPS THROUGH THE NIGHT...BUT TRANSITIONING
TO MOSTLY SHOWERS...RATHER THAN THUNDERSTORMS.

CEILINGS LOWERING 1 TO 2 THSD FT AND VSBY AROUND 3 MILES IN POST
FRONTAL SHOWERS.  CEILINGS OVER HIGH MOUNTAINS LIKELY TO DROP BELOW
1 THSD FT AND VSBY BLO 3 MILES.

MEANWHILE...DRIER AIR MOVING SOUTH INTO SOUTHEAST OHIO AND TOWARD
PKB.  SO HAVE CEILINGS STARTING TO IMPROVE/LIFT FROM THE NORTH TOWARD
06Z THURSDAY.

FORECAST CONFIDENCE: LOW.

ALTERNATE SCENARIOS: TIMING THE VARIOUS CLUSTERS OF SHOWERS AND
THUNDERSTORMS TODAY AND TONIGHT WILL LIKELY VARY.

PASSES TONIGHT...WITH WAVE ALONG FRONT LATE TONIGHT AND EARLY

&&

.NEAR TERM /THROUGH TODAY/...
MADE A FEW MINOR TWEEKS WITH POPS...AS PERSISTENT SHOWERS OVER THE
RIDGETOPS OF THE NORTHERN MOUNTAINS ARE FINALLY STARTING TO WIND
DOWN WITH THE LOSS OF HEATING.  OTHERWISE REST OF FORECAST ON TRACK.

PREVIOUS DISCUSSION...
WARM AND MUGGY CONDITIONS ACROSS THE CWA AS EXPECTED. DIURNAL CU
HAS DEVELOPED ACROSS THE CWA THIS AFTERNOON. SURFACE HIGH PRESSURE
OFF TO THE EAST CREATING A SOUTHEASTERLY FLOW ACROSS THE
MOUNTAINS...CREATING THE POSSIBILITY FOR AN ISOLATED
SHOWER/THUNDERSTORM THIS AFTERNOON AND EVENING. STILL LOOKING LIKE
ANY CONVECTION THAT IS ABLE TO DEVELOP SHOULD STAY OVER MOUNTAINS
WITH OVERALL WEAK FLOW PATTERN IN PLACE.

EXPECTING ANOTHER WARM AND MUGGY NIGHT ACROSS THE CWA...WITH FOG
DEVELOPMENT ONLY EXPECTED IN DEEP MOUNTAIN VALLEYS. INCREASED BL
FLOW...PARTICULARLY ACROSS THE NORTH...SHOULD HELP TO KEEP MUCH
FOG DEVELOPMENT AT BAY...AND KEEP TEMPERATURES ON THE WARM
SIDE...PARTICULARLY ACROSS FAR NORTHERN ZONES.

SURFACE COLD FRONT AND UPPER TROUGH APPROACH THE REGION ON
WEDNESDAY. COLD FRONT SHOULD ENTER SOUTHEAST OHIO ZONES
18-21Z...AND END UP TO THE EAST OF THE MOUNTAINS LATE WEDNESDAY
NIGHT/THURSDAY MORNING. STILL NOT EXPECTING A WIDESPREAD SEVERE
EVENT. GOOD CAPE/INSTABILITY PARTICULARLY SOUTH OF THE OHIO RIVER
WHERE LESS CLOUD COVER IS EXPECTED IN AFTERNOON HOURS...BUT NO
REAL STRONG DYNAMICS...AND 0-6KM BULK SHEAR ONLY 20-25 KTS.
HOWEVER...COULD STILL GET SEVERE HAIL OR DMG WINDS WITH ANY STORM
THAT DEVELOPS. WILL MAINTAIN THIS IN THE HWO. SPC HAS AREA IN A
SEE TEXT FOR SEVERE WEDNESDAY.

&&

.SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/...
BY LATE WEDNESDAY NIGHT...COLD FRONT EXPECTED TO BE CROSSING EAST
ACROSS THE APPALACHIANS...ALLOWING DRIER BUT WEAK NORTHERLY FLOW.
THEREFORE...LIKELY POPS STILL EXPECTED IN THE BEGINNING OF THE
PERIOD...QUICKLY IMPROVING BY EARLY THURSDAY MORNING. EXPECT A
COOL AND MUGGY NIGHT AS TEMPERATURES REACH THEIR
DEWPOINTS...PERHAPS PRODUCING AREAS OF FOG UNDER CLEAR SKIES.

DECREASED POPS TO SLIGHT CHANCE BY 12-15Z THURSDAY WITH CHANCES
ALONG THE MOUNTAINS BEFORE ALL MOVE EAST AWAY FROM THE AREA BY MID
DAY THURSDAY. MODELS AGREE IN A SECONDARY SHORTWAVE SHORTLY BEHIND
THE AXIS OF THE UPPER LEVEL TROUGH PASSING ACROSS THE AREA
THURSDAY...SO HOLD ON INTO CHANCE POPS ACROSS THE WESTERN SLOPES
THROUGH THURSDAY AFTERNOON.

ELSEWHERE...MOST OF THE LOWLAND WILL PROBABLY REMAIN DRY WITH MAX
TEMPS ONLY IN THE UPPER 70S. A BIT OF A TOUGH CALL ON SKY
COVER...CODED UP PARTLY CLOUDY SKIES FOR THE AFTERNOON HOURS FOR
THE LOWLANDS BUT SOME INDICATION THAT A FAIRLY EXTENSIVE CU FIELD
MAY REDEVELOP UNDERNEATH AFOREMENTIONED INVERSION.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
USED HPC GUIDANCE FOR MOST OF THE WEATHER ELEMENTS WITH A FEW
MINOR TWEAKS THROUGH THE PERIOD.

LIGHT NORTHERLY FLOW TURNS WEST AND SOUTHWEST AS A SURFACE HIGH
PRESSURE BUILDS FROM THE WEST FRIDAY INTO EARLY SATURDAY. ALTHOUGH

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
938 AM EDT TUE JUL 22 2014

.SYNOPSIS...
WEAK FLOW CONTINUES TODAY. FLOW BEGINS TO INCREASE TONIGHT.
MOISTURE INCREASES WEDNESDAY. COLD FRONT PASSES WEDNESDAY NIGHT.
DRIER AIR ARRIVES ON THURSDAY. HIGH PRESSURE IN FULL CONTROL FRIDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
930 AM UPDATE...TWEAKED SKY AND POP GRIDS. OTHERWISE...NO CHANGES
WERE NECESSARY.

PREVIOUS DISCUSSION FOLLOWS...
EXPECT TODAY TO BE THE SECOND OF OUR 2 DAY DOG DAY PATTERN.

NO BIG CHANGES. FOG IS LESS THIS MORNING...AS TEMPERATURES IN MANY
SPOTS ARE 1 TO 3 DEGREES MILDER...COMPARED TO 24 HOURS AGO.  BUT
LIKE MONDAY MORNING...JUST AS MUCH FOG IN OHIO AS WEST VIRGINIA.

THAT WEAK WIND FLOW CONTINUES TODAY...WITH THE WARM STABLE LAYER AT
10 TO 15 THSD FT.  WILL CONTINUE TO MENTION A CHANCE POP FOR MOUNTAIN
THERMALS THIS AFTERNOON INTO EARLY EVENING.  700 MB FLOW BEGINS TO
VEER TO WEAK WEST BY LATE IN THE DAY...SO NOT FIGURING ON CELLS
COMING OFF THE MOUNTAINS WESTWARD.  ALSO...WITH UPPER WINDS STARTING
TO HAVE A WEST TO EAST COMPONENT...SOME HAZE AND SMOKE ALOFT MAY BE
NOTICED AROUND SUNSET THIS EVENING FOR THE OHIO VALLEY COUNTIES.

FORECAST MAXIMUM TEMPERATURES TODAY ARE A DEGREE OR SO HOTTER THAN
MONDAY.

ANOTHER WARM AND MUGGY NIGHT. WITH BOUNDARY LAYER INCREASING IN THE
OHIO VALLEY...SOUTHEAST OHIO MAY BE THE WARMEST OVERNIGHT. STILL
LEFT A SLIGHT CHANCE POP THROUGH THE LATE NIGHT HOURS OVER THE
SOUTHERN MOUNTAINS INCLUDING BKW.  WILL NOT PLAY UP ANY THICK FOG
LATE TONIGHT...MAY BE SOME IN THE DEEPER MOUNTAIN
VALLEYS...DEPENDING ON LEFTOVER CLOUDS.  NOT FIGURING ON ANY THICK
FOG OVER THE WESTERN LOWLANDS.

DESPITE THE FASTER FRONTAL TIMING...STILL NO POP ABOVE 14 PCT INTO
SE OHIO BY 12Z WEDNESDAY.

&&

.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
VARIOUS SHORT-TERM NWP COMING INTO BETTER AGREEMENT WITH REGARD TO
THE QUICKER HANDLING AND PROGRESSION OF THE TROUGH/COLD FRONT
PROGGED TO AFFECT OUR AREA WED/THU.

UPPER TROUGH CONTINUES TO DIG SOUTHEASTWARD ACROSS THE GREAT LAKES
WEDNESDAY. ASSOC COLD FRONT WILL BE ENTERING NW OHIO AT 12Z WED AND
SHOULD BE NEARING PERRY COUNTY AROUND 21Z WED. AS SUCH...SPED UP THE
PROGRESSION OF LIKELY POPS INTO THE NORTHWEST ZONES BY THE 19Z-20Z
TIME FRAME. OVERALL ORGANIZED SEVERE THREAT APPEARS MINIMAL WITH
ONLY ABOUT 20KTS SHEAR. HOWEVER...WITH SBCAPE UPWARDS OF 2000J/KG
AND MLCAPE AROUND 1200-1300J/KG PRODUCING EL/S OF 40-42KFT...AND
HALFWAY DECENT MID-LVL LAPSE RATES FOR OUR REGION...IT/S POSSIBLE A
STORM OR TWO MAY REACH SEVERE LIMITS. STRONG WINDS WOULD BE THE MAIN
HAZARD...BUT LARGE HAIL IS A POSSIBILITY. NOT MUCH CHANGE WITH MAX
TEMPS FROM PREV FCST FOR MOST THE WV/VA ZONES BUT DID NUDGE TEMPS
DOWN JUST A TICK ACROSS THE NW ZONES WITH THE EARLIER ARRIVAL OF
DENSE CLOUD COVER. STILL EXPECTING UPPER 80S AND A FEW 90S ACROSS
THE CENTRAL AND EASTERN LOWLANDS.

FRONT WILL CONTINUE SOUTHEASTWARD BECOMING LOCATED NEAR THE I79
CORRIDOR BTWN 00Z THU AND 03Z THU...AND THROUGH THE FORECAST AREA BY
09Z - 12Z THU. HAVE ONLY SLIGHT CHANCE POPS FOR SE OHIO BY 06Z THU
WITH LIKELY POPS CONTINUING IN THE MOUNTAINS...WITH MID/HIGH CHANCE
POPS IN THE MOUNTAINS AND NO PUBLIC POPS NEAR AND WEST OF THE OHIO
BY 12Z THU. ALSO ENDED THUNDER CHANCES WITH THE PROGRESSION OF THE
FRONT ITSELF. WITH THE QUICKER ARRIVAL OF THE FRONT...LOWERED MINS
JUST A BIT OVERALL...BUT PARTICULARLY OVER THE NW ZONES WHERE
DEWPOINTS SHOULD BE IN THE MID 50S BY THE 09Z-12Z THU TIME FRAME.
MIGHT ALSO SEE SOME BRIEF GUSTS AROUND 15KTS OR SO WITH THE PASSAGE
OF THE FRONT ITSELF.

THE BASE OF THE UPPER TROUGH FINALLY SWINGS ACROSS BTWN 12Z-18Z THU
WITH SFC HIGH PRESSURE CONTINUING TO BUILD IN OUT OF THE NORTHWEST.
WILL KEEP AT LEAST SLIGHT TO LOW CHANCE POPS PRIMARILY IN THE
EASTERN MOUNTAINS WITH A GOOD AMOUNT OF LLVL MOISTURE TRAPPED
UNDERNEATH A STRENGTHENING SUBSIDENCE INVERSION. ELSEWHERE...MOST
LOWLAND LOCATIONS WILL PROBABLY REMAIN DRY WITH MAX TEMPS ONLY IN
THE UPPER 70S. A BIT OF A TOUGH CALL ON SKY COVER...CODED UP PARTLY
CLOUDY SKIES FOR THE AFTERNOON HOURS FOR THE LOWLANDS BUT SOME
INDICATION THAT A FAIRLY EXTENSIVE CU FIELD MAY REDEVELOP UNDERNEATH
AFOREMENTIONED INVERSION. ENDED ALL PUBLIC POPS BY 03Z FRI WITH
CUMULUS DISSIPATING OVERNIGHT BUT HANGING ON LONGER OF COURSE IN THE
EASTERN MOUNTAINS. LOWERED MINS BY A GOOD 4-6 DEGREES PRETTY MUCH
ACROSS THE BOARD WITH MINS MAINLY IN THE UPPER 50S EXPECTED FOR THE
LOWLANDS BY EARLY FRI.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
POPULATED GRIDS WITH HPC GUIDANCE WITH A FEW MINOR TWEAKS. 5H
TROUGH SLIDES EAST...WHILE AT THE SFC THERE WILL BE AND AREA OF
WEAK HIGH PRESSURE...WITH GENERALLY DRY ATMOSPHERIC COLUMN ON
FRIDAY AND SATURDAY. A LARGE OCCLUDING SYSTEM MEANDERS SOUTH FOR
SUNDAY...AS CUT-OFF LOW DEVELOPS OVER THE GREAT LAKES. BOTH ECMWF
AND GFS IN FAIRLY GOOD AGREEMENT IN PLAYING OUT THIS SCENARIO LATE
IN THE PERIOD FOR A GENERAL UPSWING IN PRECIPITATION CHANCES BY
SUNDAY.

&&

.AVIATION /14Z TUESDAY THROUGH SATURDAY/...
PREDAWN FOG WAS NOT AS WIDESPREAD AS 24 HOURS AGO OR FORECAST FOR
THIS PREDAWN.  THOUGH...LOW CLOUDS ARE STILL LURKING ON THE EASTERN
SLOPES THOUGH AT DAWN...INCLUDING THE UPPER GREENBRIER VALLEY. SO
SOME CEILINGS NEAR 1 THSD FT INTO 14Z THERE...BEFORE LIFTING.

ISOLATED TO SCATTERED SLOW MOVING CONVECTION OVER MOUNTAIN COUNTIES
AGAIN TODAY...FIRST PROBABLY FORMING 16Z TO 19Z. WITH MID LEVEL FLOW
STARTING TO VEER TO WEST LATE TODAY...DID NOT INCLUDE ANY CONVECTION
IN CKB TO CRW TAFS. A FEW SHOWERS MAY LINGER OVER SOUTHERN MOUNTAINS
INCLUDING BKW VCNTY AFTER DARK THIS EVENING.

CEILINGS 2 TO 4 THSD FT BKN OVER MOUNTAINS NEAR
CONVECTION...OTHERWISE CLOUDS MOSTLY 3 TO 5 THSD FT AGL SCATTERED
