.SYNOPSIS...
SNOW TAPERING OFF TONIGHT. HIGH PRESSURE SATURDAY. ANOTHER LOW
PRESSURE SYSTEM SUNDAY NIGHT AND MONDAY WITH WINTRY PRECIPITATION.

&&

.NEAR TERM /THROUGH SATURDAY/...
SNOW SHOWERS GRADUALLY TAPERING OFF TO FLURRIES ACROSS THE LOWLANDS.
SNOW SHOWERS WILL LINGER IN THE MOUNTAINS INTO TONIGHT...BEFORE
TAPERING OFF AS FLURRIES AS WELL. HAVE RATHER GUSTY WINDS ACROSS
MUCH OF CWA IN THE CAA BEHIND ARCTIC FRONT WHICH CROSSED THIS
MORNING. THESE WINDS WILL BEGIN TO WANE FROM WEST TO EAST TONIGHT.
WILL BE A BLUSTERY NIGHT. HAVE WIND CHILL VALUES IN THE NORTHERN
MOUNTAINS OF AROUND -5...AND EVEN A TOUCH LOWER ON HIGHER PEAKS.
HIGH PRESSURE AROUND FOR SATURDAY. WILL STILL BE A COOL DAY WITH
BELOW AVERAGE HIGHS...BUT A GOOD AMOUNT OF SUNSHINE SHOULD HELP EASE
THE CHILL.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
STILL A COMPLICATED WEATHER PATTERN IN THE SHORT TERM PERIOD...BUT
MODELS ARE GRADUALLY TRENDING TOWARDS A WARMER SOLUTION. GFS MODEL
CONTINUES TO TAKE THE TRACK OF THE LOW FARTHER SOUTH...RESULTING IN
A COLDER SOLUN THAN NAM OR CANADIAN. WITH THE OVERALL TREND TOWARDS
WARMER SOLUTION...LEANED A LITTLE MORE TOWARDS THE NAM THAN GFS
TEMPERATURE WISE DURING THE PERIOD. THIS...WITH THE LOW PATH THROUGH
OHIO...WILL RESULT IN WARM WEDGE EFFECTS ACROSS MUCH OF THE WV AND
PARTS OF SOUTHEAST OHIO LOWLANDS...THUS LIMITING SNOWFALL AMOUNTS.
AT THIS POINT...ONLY NORTHERN BORDERS OF THE CWA WILL REMAIN MOSTLY
SNOW OR A WINTRY MIX...ALONG WITH MOUNTAINOUS COUNTIES.

THIS LOOKS TO BE A DECENT QPF EVENT...WITH STRONG LLJ
DEVELOPING...AIDING IN MOISTURE TRANSPORT TO THE REGION. GENERALLY
HAVE 0.7 TO 0.9 INCHES QPF FIGURED ACROSS PARTS OF SOUTHEAST
OHIO...WITH 0.5 TO 0.7 INCHES ACROSS SOUTHERN 2/3 OF CWA.

THE LOW PRESSURE SYSTEM WILL GRADUALLY PUSH OFF TO THE NORTH AND
EAST SUNDAY NIGHT...WITH A GRADUAL CHANGE OVER TO A WINTRY
MIX...THEN ALL SNOW OVERNIGHT INTO MONDAY AS COLDER AIR RUSHES IN ON
THE BACK SIDE OF THE LOW. HAVE FALLING TEMPERATURES ON MONDAY/NON
DIURNAL.

AT THIS POINT...TAKING THE NORTHERLY TRACK/WARMER SOLUTION INTO
ACCOUNT...HAVE DECIDED TO ISSUE A WINTER STORM WATCH FOR PERRY AND
MORGAN COUNTIES IN OHIO...IN EFFECT FROM 06Z SUNDAY TO 12Z MONDAY.
AT THIS POINT...HAVE A GENERAL 4 TO 6 ACROSS MORGAN COUNTY...WITH A
GENERAL 4 TO 8 ACROSS PERRY. THE NORTHERN PORTIONS OF ATHENS AND
WASHINGTON COUNTIES COULD SEE WARNING CRITERIA...BUT AT THIS
POINT...IT IS ISOLATED TO THE NORTHERN PORTIONS...AND NOT COUNTY
WIDE. HOWEVER...IT IS LOOKING LIKE MUCH OF SOUTHEAST OHIO...AND SOME
ADJACENT WV COUNTIES WILL AT LEAST SEE ADVISORY CRITERIA...WHICH
WILL BE HIGHLIGHTED IN THE HWO...AND ISSUED IN LATER SHIFTS IF
NECESSARY.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
A QUIET PERIOD FOR THE MOST PART THIS PERIOD WITH NORTHWEST FLOW
ALOFT PREVAILING. MODELS FORECAST A CLIPPER SYSTEM AND ASSOCIATED
COLD FRONT TO DROP SOUTHEASTWARD ACROSS THE OHIO VALLEY WEDNESDAY
NIGHT. AHEAD OF THE FRONT...A SOUTHERLY FLOW AND SOME SUNSHINE
TUESDAY AND WEDNESDAY WILL BRING TEMPERATURES UP TO NEAR NORMAL BY
WEDNESDAY. THIS SYSTEM LACKS DYNAMICS AND MOISTURE SO THAT JUST A
FEW RAIN AND SNOW SHOWERS ARE FORECAST TO ACCOMPANY THE FRONT
WEDNESDAY NIGHT. HOWEVER...ANOTHER VERY COLD AIRMASS WILL FOLLOW THE
FRONT FOR THE REMAINDER OF THE WORK WEEK...WITH TEMPERATURES WELL
BELOW NORMAL AGAIN. A FEW SNOW SHOWERS MAY LINGER IN THE MOUNTAINS
THURSDAY...BUT NOT MUCH IS EXPECTED AS UPSLOPE AND MOISTURE IS
LIMITED.

&&

.AVIATION /21Z FRIDAY THROUGH WEDNESDAY/...
IN THE WAKE OF THE COLD FRONT...FLURRIES CONTINUING ACROSS MUCH OF
FORECAST AREA. SNOW SHOWERS STILL HANGING ON IN THE MOUNTAINS WITH
SOME MVFR TO IFR. MVFR CLOUDS MAY REFORM ACROSS THE NORTH THIS
AFTERNOON. GUSTY WINDS EXPECTED TODAY...SUBSIDING SOME TONIGHT
ACROSS THE LOWLANDS WHILE LINGERING IN THE HIGHER TERRAIN. VRB

.SYNOPSIS...
SNOW TAPERING OFF TONIGHT. HIGH PRESSURE SATURDAY. ANOTHER LOW
PRESSURE SYSTEM SUNDAY NIGHT AND MONDAY WITH WINTRY PRECIPITATION.

&&

.NEAR TERM /THROUGH SATURDAY/...
SNOW SHOWERS GRADUALLY TAPERING OFF TO FLURRIES ACROSS THE LOWLANDS.
SNOW SHOWERS WILL LINGER IN THE MOUNTAINS INTO TONIGHT...BEFORE
TAPERING OFF AS FLURRIES AS WELL. HAVE RATHER GUSTY WINDS ACROSS
MUCH OF CWA IN THE CAA BEHIND ARCTIC FRONT WHICH CROSSED THIS
MORNING. THESE WINDS WILL BEGIN TO WANE FROM WEST TO EAST TONIGHT.
WILL BE A BLUSTERY NIGHT. HAVE WIND CHILL VALUES IN THE NORTHERN
MOUNTAINS OF AROUND -5...AND EVEN A TOUCH LOWER ON HIGHER PEAKS.
HIGH PRESSURE AROUND FOR SATURDAY. WILL STILL BE A COOL DAY WITH
BELOW AVERAGE HIGHS...BUT A GOOD AMOUNT OF SUNSHINE SHOULD HELP EASE
THE CHILL.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
STILL A COMPLICATED WEATHER PATTERN IN THE SHORT TERM PERIOD...BUT
MODELS ARE GRADUALLY TRENDING TOWARDS A WARMER SOLUTION. GFS MODEL
CONTINUES TO TAKE THE TRACK OF THE LOW FARTHER SOUTH...RESULTING IN
A COLDER SOLUN THAN NAM OR CANADIAN. WITH THE OVERALL TREND TOWARDS
WARMER SOLUTION...LEANED A LITTLE MORE TOWARDS THE NAM THAN GFS
TEMPERATURE WISE DURING THE PERIOD. THIS...WITH THE LOW PATH THROUGH
OHIO...WILL RESULT IN WARM WEDGE EFFECTS ACROSS MUCH OF THE WV AND
PARTS OF SOUTHEAST OHIO LOWLANDS...THUS LIMITING SNOWFALL AMOUNTS.
AT THIS POINT...ONLY NORTHERN BORDERS OF THE CWA WILL REMAIN MOSTLY
SNOW OR A WINTRY MIX...ALONG WITH MOUNTAINOUS COUNTIES.

THIS LOOKS TO BE A DECENT QPF EVENT...WITH STRONG LLJ
DEVELOPING...AIDING IN MOISTURE TRANSPORT TO THE REGION. GENERALLY
HAVE 0.7 TO 0.9 INCHES QPF FIGURED ACROSS PARTS OF SOUTHEAST
OHIO...WITH 0.5 TO 0.7 INCHES ACROSS SOUTHERN 2/3 OF CWA.

THE LOW PRESSURE SYSTEM WILL GRADUALLY PUSH OFF TO THE NORTH AND
EAST SUNDAY NIGHT...WITH A GRADUAL CHANGE OVER TO A WINTRY
MIX...THEN ALL SNOW OVERNIGHT INTO MONDAY AS COLDER AIR RUSHES IN ON
THE BACK SIDE OF THE LOW. HAVE FALLING TEMPERATURES ON MONDAY/NON
DIURNAL.

AT THIS POINT...TAKING THE NORTHERLY TRACK/WARMER SOLUTION INTO
ACCOUNT...HAVE DECIDED TO ISSUE A WINTER STORM WATCH FOR PERRY AND
MORGAN COUNTIES IN OHIO...IN EFFECT FROM 06Z SUNDAY TO 12Z MONDAY.
AT THIS POINT...HAVE A GENERAL 4 TO 6 ACROSS MORGAN COUNTY...WITH A
GENERAL 4 TO 8 ACROSS PERRY. THE NORTHERN PORTIONS OF ATHENS AND
WASHINGTON COUNTIES COULD SEE WARNING CRITERIA...BUT AT THIS
POINT...IT IS ISOLATED TO THE NORTHERN PORTIONS...AND NOT COUNTY
WIDE. HOWEVER...IT IS LOOKING LIKE MUCH OF SOUTHEAST OHIO...AND SOME
ADJACENT WV COUNTIES WILL AT LEAST SEE ADVISORY CRITERIA...WHICH
WILL BE HIGHLIGHTED IN THE HWO...AND ISSUED IN LATER SHIFTS IF
NECESSARY.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
A QUIET PERIOD FOR THE MOST PART THIS PERIOD WITH NORTHWEST FLOW
ALOFT PREVAILING. MODELS FORECAST A CLIPPER SYSTEM AND ASSOCIATED
COLD FRONT TO DROP SOUTHEASTWARD ACROSS THE OHIO VALLEY WEDNESDAY
NIGHT. AHEAD OF THE FRONT...A SOUTHERLY FLOW AND SOME SUNSHINE
TUESDAY AND WEDNESDAY WILL BRING TEMPERATURES UP TO NEAR NORMAL BY
WEDNESDAY. THIS SYSTEM LACKS DYNAMICS AND MOISTURE SO THAT JUST A
FEW RAIN AND SNOW SHOWERS ARE FORECAST TO ACCOMPANY THE FRONT
WEDNESDAY NIGHT. HOWEVER...ANOTHER VERY COLD AIRMASS WILL FOLLOW THE
FRONT FOR THE REMAINDER OF THE WORK WEEK...WITH TEMPERATURES WELL
BELOW NORMAL AGAIN. A FEW SNOW SHOWERS MAY LINGER IN THE MOUNTAINS
THURSDAY...BUT NOT MUCH IS EXPECTED AS UPSLOPE AND MOISTURE IS
LIMITED.

&&

.AVIATION /20Z FRIDAY THROUGH WEDNESDAY/...
IN THE WAKE OF THE COLD FRONT...FLURRIES CONTINUING ACROSS MUCH OF
FORECAST AREA. SNOW SHOWERS STILL HANGING ON IN THE MOUNTAINS WITH
SOME MVFR TO IFR. MVFR CLOUDS MAY REFORM ACROSS THE NORTH THIS
AFTERNOON. GUSTY WINDS EXPECTED TODAY...SUBSIDING SOME TONIGHT
ACROSS THE LOWLANDS WHILE LINGERING IN THE HIGHER TERRAIN. VRB

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
214 PM EST FRI JAN 30 2015

.SYNOPSIS...
SNOW TAPERING OFF TONIGHT. HIGH PRESSURE SATURDAY. ANOTHER LOW
PRESSURE SYSTEM SUNDAY NIGHT AND MONDAY WITH WINTRY PRECIPITATION.

&&

.NEAR TERM /THROUGH SATURDAY/...
SNOW SHOWERS GRADUALLY TAPERING OFF TO FLURRIES ACROSS THE LOWLANDS.
SNOW SHOWERS WILL LINGER IN THE MOUNTAINS INTO TONIGHT...BEFORE
TAPERING OFF AS FLURRIES AS WELL. HAVE RATHER GUSTY WINDS ACROSS
MUCH OF CWA IN THE CAA BEHIND ARCTIC FRONT WHICH CROSSED THIS
MORNING. THESE WINDS WILL BEGIN TO WANE FROM WEST TO EAST TONIGHT.
WILL BE A BLUSTERY NIGHT. HAVE WIND CHILL VALUES IN THE NORTHERN
MOUNTAINS OF AROUND -5...AND EVEN A TOUCH LOWER ON HIGHER PEAKS.
HIGH PRESSURE AROUND FOR SATURDAY. WILL STILL BE A COOL DAY WITH
BELOW AVERAGE HIGHS...BUT A GOOD AMOUNT OF SUNSHINE SHOULD HELP EASE
THE CHILL.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
STILL A COMPLICATED WEATHER PATTERN IN THE SHORT TERM PERIOD...BUT
MODELS ARE GRADUALLY TRENDING TOWARDS A WARMER SOLUTION. GFS MODEL
CONTINUES TO TAKE THE TRACK OF THE LOW FARTHER SOUTH...RESULTING IN
A COLDER SOLUN THAN NAM OR CANADIAN. WITH THE OVERALL TREND TOWARDS
WARMER SOLUTION...LEANED A LITTLE MORE TOWARDS THE NAM THAN GFS
TEMPERATURE WISE DURING THE PERIOD. THIS...WITH THE LOW PATH THROUGH
OHIO...WILL RESULT IN WARM WEDGE EFFECTS ACROSS MUCH OF THE WV AND
PARTS OF SOUTHEAST OHIO LOWLANDS...THUS LIMITING SNOWFALL AMOUNTS.
AT THIS POINT...ONLY NORTHERN BORDERS OF THE CWA WILL REMAIN MOSTLY
SNOW OR A WINTRY MIX...ALONG WITH MOUNTAINOUS COUNTIES.

THIS LOOKS TO BE A DECENT QPF EVENT...WITH STRONG LLJ
DEVELOPING...AIDING IN MOISTURE TRANSPORT TO THE REGION. GENERALLY
HAVE 0.7 TO 0.9 INCHES QPF FIGURED ACROSS PARTS OF SOUTHEAST
OHIO...WITH 0.5 TO 0.7 INCHES ACROSS SOUTHERN 2/3 OF CWA.

THE LOW PRESSURE SYSTEM WILL GRADUALLY PUSH OFF TO THE NORTH AND
EAST SUNDAY NIGHT...WITH A GRADUAL CHANGE OVER TO A WINTRY
MIX...THEN ALL SNOW OVERNIGHT INTO MONDAY AS COLDER AIR RUSHES IN ON
THE BACK SIDE OF THE LOW. HAVE FALLING TEMPERATURES ON MONDAY/NON
DIURNAL.

AT THIS POINT...TAKING THE NORTHERLY TRACK/WARMER SOLUTION INTO
ACCOUNT...HAVE DECIDED TO ISSUE A WINTER STORM WATCH FOR PERRY AND
MORGAN COUNTIES IN OHIO...IN EFFECT FROM 06Z SUNDAY TO 12Z MONDAY.
AT THIS POINT...HAVE A GENERAL 4 TO 6 ACROSS MORGAN COUNTY...WITH A
GENERAL 4 TO 8 ACROSS PERRY. THE NORTHERN PORTIONS OF ATHENS AND
WASHINGTON COUNTIES COULD SEE WARNING CRITERIA...BUT AT THIS
POINT...IT IS ISOLATED TO THE NORTHERN PORTIONS...AND NOT COUNTY
WIDE. HOWEVER...IT IS LOOKING LIKE MUCH OF SOUTHEAST OHIO...AND SOME
ADJACENT WV COUNTIES WILL AT LEAST SEE ADVISORY CRITERIA...WHICH
WILL BE HIGHLIGHTED IN THE HWO...AND ISSUED IN LATER SHIFTS IF
NECESSARY.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
A SNOW SCENARIO CONTINUES SUNDAY NIGHT INTO EARLY MONDAY AS MODELS
HAVE LOW PRESSURE SLIDING JUST SOUTH OF THE AREA. HOWEVER...IN THE
EASTERLY FLOW THAT SETS UP NORTH OF THE FORECASTED LOW TRACK...WE
WILL HAVE TO WATCH FOR A MODEST WARM WEDGE JUST WEST OF THE
MOUNTAINS SUNDAY EVENING WITH A WEAK INVERTED SURFACE TROUGH JUST
WEST OF THE MOUNTAINS. MOST OF THE MODELS ARE HINTING AT THIS. SO
FOR NOW...WE CONTINUE TO PAINT A RAIN/SNOW MIX OVER THE FAR SOUTH
SUNDAY EVENING...BUT THEN QUICKLY TURN IT ALL TO SNOW AS THE WINDS
TURN NORTHERLY. ELSEWHERE...A GENERAL SNOWFALL IS FORECAST. SNOW
TOTAL ACCUMULATIONS FOR THE ENTIRE EVENT MAY REACH 3 TO 5 INCHES
ACROSS THE NORTH...AND 1 TO 3 INCHES ACROSS THE SOUTH. TEMPERATURES
WILL BE WELL BELOW NORMAL.

DRY AND COLD HIGH PRESSURE BUILDS IN LATER MONDAY INTO TUESDAY WITH
CONTINUED BELOW NORMAL TEMPERATURES.

FOR WEDNESDAY...LOOKS LIKE ANOTHER COLD FRONT WILL PASS
THROUGH...BUT ENOUGH WARMING MAY BE DRAWN NORTHWARD AHEAD OF IT FOR
MOSTLY RAIN SHOWERS. SCATTERED SNOW SHOWERS BEHIND THE FRONT
WEDNESDAY NIGHT TO BE FOLLOWED BY ANOTHER COLD HIGH PRESSURE AGAIN
THURSDAY.

&&

.AVIATION /19Z FRIDAY THROUGH WEDNESDAY/...
IN THE WAKE OF THE COLD FRONT...FLURRIES CONTINUING ACROSS MUCH OF
FORECAST AREA. SNOW SHOWERS STILL HANGING ON IN THE MOUNTAINS WITH
SOME MVFR TO IFR. MVFR CLOUDS MAY REFORM ACROSS THE NORTH THIS
AFTERNOON. GUSTY WINDS EXPECTED TODAY...SUBSIDING SOME TONIGHT

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
931 AM EST FRI JAN 30 2015

.SYNOPSIS...
SNOW WILL FALL ACROSS THE FORECAST AREA TODAY WITH LIGHT
ACCUMULATIONS. HIGH PRESSURE SATURDAY. ANOTHER LOW PRESSURE
SYSTEM SUNDAY NIGHT AND MONDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
930 AM UPDATE...EXTENDED WINTER WEATHER ADVISORY IN THE NORTHERN
MOUNTAINS FOR A FEW MORE HOURS. ALSO TWEAKS HOURLY GRIDS BASED ON
CURRENT OBS AND TRENDS.

PREVIOUS DISCUSSION...COLD FRONT BRINGING PERIODS OF SNOW AND GUSTY WINDS TO
THE AREA THIS MORNING. NW FLOW WILL KEEP UPSLOPE SNOW SHOWERS
GOING ACROSS THE FORECAST AREA FOR MUCH OF THE DAY. IN
GENERAL...THE LOWLANDS SHOULD SEE GENERALLY A HALF TO 1.5 INCHES
OF NEW SNOW...MOST OF WHICH SHOULD FALL THIS MORNING. 3 TO 5
INCHES IS EXPECTED IN THE NORTHERN MOUNTAINOUS COUNTIES...AND EVEN
A BIT MORE AT HIGHER ELEVATIONS. WILL CONTINUE WINTER WEATHER
ADVISORY AS IT IS.

WINDS SHOULD REMAIN GUSTY THROUGHOUT THE DAY.

WINDS WILL DIE DOWN TONIGHT AS SNOW SHOWERS DISSIPATE AS HIGH
PRESSURE BRIEFLY BUILDS OVER THE AREA.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY/...
HIGH PRESSURE PROVIDES DRY BUT COLD WEATHER SATURDAY. THIS BRINGS
LONG PERIODS OF SUNSHINE WITH TEMPERATURES REACHING THE MID 30S TO
40 ACROSS THE SOUTHERN COAL FIELDS AND NORTHEAST KY...RANGING TO
THE LOWER 30S ELSEWHERE.

A SFC LOW PRESSURE SYSTEM APPROACHES FROM THE WEST SATURDAY NIGHT
INTO SUNDAY. AS IT GETS CLOSER...IT WILL PUMP WARMER AIR TO THE
REGION MAKING THE ONSET OF PCPN TO FALL AS LIQUID. CURRENTLY
MODELS TRACKS ITS CENTER ACROSS WV...SUGGESTING LONGER PERIODS OF
RAIN PER WARMER TEMPERATURES. HOWEVER...WWD THINKING ON A FURTHER
SOUTH TRACK WHICH WILL PUT THE AREA IN A THREAT FOR SIGNIFICANT
ACCUMULATING SNOW...ESPECIALLY ACROSS THE NORTHERN PORTIONS OF
SOUTHEAST OH...WV...AND THE WV NORTHERN MOUNTAINS. WWD SUGGEST
THESE AREAS COULD RECEIVE 6 TO 8 INCHES OF SNOW BY MONDAY MORNING.
AT THIS TIME...WILL WAIT FOR MODELS CONSISTENCY ON THE TRACK OF
THIS LOW PRESSURE BEFORE ISSUING ANY HEADLINES. HOWEVER...KEPT
MENTIONING IN THE HWO.

WENT CLOSER TO THE BIAS CORRECTED CONSENSUS MOS FOR TEMPERATURES
THROUGH THE PERIOD WITH MINOR TWEAKS.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
A SNOW SCENARIO CONTINUES SUNDAY NIGHT INTO EARLY MONDAY AS MODELS
HAVE LOW PRESSURE SLIDING JUST SOUTH OF THE AREA. HOWEVER...IN THE
EASTERLY FLOW THAT SETS UP NORTH OF THE FORECASTED LOW TRACK...WE
WILL HAVE TO WATCH FOR A MODEST WARM WEDGE JUST WEST OF THE
MOUNTAINS SUNDAY EVENING WITH A WEAK INVERTED SURFACE TROUGH JUST
WEST OF THE MOUNTAINS. MOST OF THE MODELS ARE HINTING AT THIS. SO
FOR NOW...WE CONTINUE TO PAINT A RAIN/SNOW MIX OVER THE FAR SOUTH
SUNDAY EVENING...BUT THEN QUICKLY TURN IT ALL TO SNOW AS THE WINDS
TURN NORTHERLY. ELSEWHERE...A GENERAL SNOWFALL IS FORECAST. SNOW
TOTAL ACCUMULATIONS FOR THE ENTIRE EVENT MAY REACH 3 TO 5 INCHES
ACROSS THE NORTH...AND 1 TO 3 INCHES ACROSS THE SOUTH. TEMPERATURES
WILL BE WELL BELOW NORMAL.

DRY AND COLD HIGH PRESSURE BUILDS IN LATER MONDAY INTO TUESDAY WITH
CONTINUED BELOW NORMAL TEMPERATURES.

FOR WEDNESDAY...LOOKS LIKE ANOTHER COLD FRONT WILL PASS
THROUGH...BUT ENOUGH WARMING MAY BE DRAWN NORTHWARD AHEAD OF IT FOR
MOSTLY RAIN SHOWERS. SCATTERED SNOW SHOWERS BEHIND THE FRONT
WEDNESDAY NIGHT TO BE FOLLOWED BY ANOTHER COLD HIGH PRESSURE AGAIN
THURSDAY.

SNOW WILL FALL ACROSS THE FORECAST AREA TODAY WITH LIGHT
ACCUMULATIONS. HIGH PRESSURE SATURDAY. ANOTHER LOW PRESSURE
SYSTEM SUNDAY NIGHT AND MONDAY IS LIKELY TO BRING ACCUMULATING
SNOW TO THE AREA.

&&

.NEAR TERM /THROUGH TONIGHT/...
COLD FRONT BRINGING PERIODS OF SNOW AND GUSTY WINDS TO THE AREA
THIS MORNING. NW FLOW WILL KEEP UPSLOPE SNOW SHOWERS GOING ACROSS
THE FORECAST AREA FOR MUCH OF THE DAY. IN GENERAL...THE LOWLANDS
SHOULD SEE GENERALLY A HALF TO 1.5 INCHES OF NEW SNOW...MOST OF
WHICH SHOULD FALL THIS MORNING. 3 TO 5 INCHES IS EXPECTED IN THE
NORTHERN MOUNTAINOUS COUNTIES...AND EVEN A BIT MORE AT HIGHER
ELEVATIONS. WILL CONTINUE WINTER WEATHER ADVISORY AS IT IS.

WINDS SHOULD REMAIN GUSTY THROUGHOUT THE DAY.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY/...
HIGH PRESSURE PROVIDES DRY BUT COLD WEATHER SATURDAY. THIS BRINGS
LONG PERIODS OF SUNSHINE WITH TEMPERATURES REACHING THE MID 30S TO
40 ACROSS THE SOUTHERN COAL FIELDS AND NORTHEAST KY...RANGING TO
THE LOWER 30S ELSEWHERE.

A SFC LOW PRESSURE SYSTEM APPROACHES FROM THE WEST SATURDAY NIGHT
INTO SUNDAY. AS IT GETS CLOSER...IT WILL PUMP WARMER AIR TO THE
REGION MAKING THE ONSET OF PCPN TO FALL AS LIQUID. CURRENTLY
MODELS TRACKS ITS CENTER ACROSS WV...SUGGESTING LONGER PERIODS OF
RAIN PER WARMER TEMPERATURES. HOWEVER...WWD THINKING ON A FURTHER
SOUTH TRACK WHICH WILL PUT THE AREA IN A THREAT FOR SIGNIFICANT
ACCUMULATING SNOW...ESPECIALLY ACROSS THE NORTHERN PORTIONS OF
SOUTHEAST OH...WV...AND THE WV NORTHERN MOUNTAINS. WWD SUGGEST
THESE AREAS COULD RECEIVE 6 TO 8 INCHES OF SNOW BY MONDAY MORNING.
AT THIS TIME...WILL WAIT FOR MODELS CONSISTENCY ON THE TRACK OF
THIS LOW PRESSURE BEFORE ISSUING ANY HEADLINES. HOWEVER...KEPT
MENTIONING IN THE HWO.

WENT CLOSER TO THE BIAS CORRECTED CONSENSUS MOS FOR TEMPERATURES
THROUGH THE PERIOD WITH MINOR TWEAKS.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
A SNOW SCENARIO CONTINUES SUNDAY NIGHT INTO EARLY MONDAY AS MODELS
HAVE LOW PRESSURE SLIDING JUST SOUTH OF THE AREA. HOWEVER...IN THE
EASTERLY FLOW THAT SETS UP NORTH OF THE FORECASTED LOW TRACK...WE
WILL HAVE TO WATCH FOR A MODEST WARM WEDGE JUST WEST OF THE
MOUNTAINS SUNDAY EVENING WITH A WEAK INVERTED SURFACE TROUGH JUST
WEST OF THE MOUNTAINS. MOST OF THE MODELS ARE HINTING AT THIS. SO
FOR NOW...WE CONTINUE TO PAINT A RAIN/SNOW MIX OVER THE FAR SOUTH
SUNDAY EVENING...BUT THEN QUICKLY TURN IT ALL TO SNOW AS THE WINDS
TURN NORTHERLY. ELSEWHERE...A GENERAL SNOWFALL IS FORECAST. SNOW
TOTAL ACCUMULATIONS FOR THE ENTIRE EVENT MAY REACH 3 TO 5 INCHES
ACROSS THE NORTH...AND 1 TO 3 INCHES ACROSS THE SOUTH. TEMPERATURES
WILL BE WELL BELOW NORMAL.

DRY AND COLD HIGH PRESSURE BUILDS IN LATER MONDAY INTO TUESDAY WITH
CONTINUED BELOW NORMAL TEMPERATURES.

FOR WEDNESDAY...LOOKS LIKE ANOTHER COLD FRONT WILL PASS
THROUGH...BUT ENOUGH WARMING MAY BE DRAWN NORTHWARD AHEAD OF IT FOR
MOSTLY RAIN SHOWERS. SCATTERED SNOW SHOWERS BEHIND THE FRONT
WEDNESDAY NIGHT TO BE FOLLOWED BY ANOTHER COLD HIGH PRESSURE AGAIN
THURSDAY.

&&

.AVIATION /08Z FRIDAY THROUGH TUESDAY/...
COLD FRONT MOVING THROUGH THE AREA WILL BRING SNOW TODAY WITH
GENERALLY MVFR CONDITIONS. PERIODS OF IFR ARE EXPECTED IN HEAVIER
SNOW BANDS WHICH SHOULD LAST A FEW HOURS. FLIGHT CONDITIONS
IMPROVE IN THE AFTERNOON...EXCEPT AT MOUNTAINOUS TAF SITES WHERE
MVFR WILL LIKELY PREDOMINATE. ALSO...GUSTY WINDS THROUGH THE TAF PERIOD.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z SATURDAY...

FORECAST CONFIDENCE: MEDIUM.

ALTERNATE SCENARIO: TIMING OF PRECIPITATION AND LOWER CIGS/VSBYS
COULD VARY...ESPECIALLY IFR. THE GUSTY WINDS WILL COME AND GO.

THE MODELS SEEM TO BE AT A CROSS ROADS ON HOW TO HANDLE THE WEEKEND
SYSTEM. MODELS AGREE IN A PACIFIC SYSTEM CUTTING UNDER THE HIGH
AMPLITUDE WESTERN U.S. UPPER RIDGE AND CLOSING OFF OVER THE
SOUTHWESTERN STATES EARLY IN THE WEEKEND. THE BIG QUESTION IS HOW A
NORTHERN STREAM SHORT DROPPING OVER THIS WESTERN UPPER RIDGE
INTERACTS WITH THE SOUTHERN STREAM SYSTEM. THE LATEST MODEL RUNS
CONTINUE TO DIVERGE. THE 12Z GFS PUTS ALMOST ALL ITS EMPHASIS ON
LEAVING MOST OF THE SOUTHWESTERN UPPER LOW ENERGY IN PLACE AND
DRIVING THE NORTHERN STREAM SHORT WAVE AND COLD FRONT ACROSS THE
AREA SUNDAY. THE 12Z NAM THRU 84 HOURS HINTS AT THIS ALSO. THE 12Z
CMC STILL WANTS TO PHASE THE TWO STREAMS AND DRIVE A STRONG LOW UP
TOWARD THE GREAT LAKES SUNDAY. THE SREF AND 00Z UKMET/EURO ARE IN
BETWEEN THESE TWO SOLUTIONS. AT THIS POINT...IN COORDINATION WITH
WPC GRAPHICS...CHOSE TO ADJUST TO A SLIGHTLY MORE SOUTHERN
TRACK...WHICH STILL CARRIES A DECENT CHUNK OF SOUTHERN ENERGY JUST
OUT AHEAD OF THE NORTHERN STREAM SYSTEM. THIS SCENARIO HAS THE
SURFACE LOW MOVING ACROSS THE NORTHERN PART OF THE AREA ON
SUNDAY...THEN DRIVING A COLD FRONT RAPIDLY ACROSS THE AREA EARLY
SUNDAY NIGHT. SO...SENSIBLE WEATHER INCLUDES INITIALLY WINTRY
PRECIPITATION EARLY SUNDAY...THEN CHANGING TO RAIN DURING SUNDAY
CENTRAL AND SOUTH...AND KEEPING AT LEAST A MIX ACROSS SOUTHEAST OHIO
AND NORTHERN WEST VIRGINIA NEAR THE TRACK OF THE LOW...THEN RAPIDLY
CHANGING TO SNOW ALL AREAS EARLY SUNDAY NIGHT AS THE COLD AIR RUSHES
BACK IN. SNOW SHOWERS WILL CONTINUE INTO AT LEAST MONDAY MORNING
WITH A WRAPAROUND MOISTURE FIELD. SNOW SHOWERS THEN WIND DOWN FROM
WEST TO EAST DURING MONDAY AS HIGH PRESSURE BUILDS IN THRU MID WEEK.

WEATHER STARTS OUT DRY...BUT COLD SATURDAY MORNING...AS HIGH

SOME MODERATION IN TEMPERATURES EXPECTED SATURDAY AFTERNOON...AS
SOUTHERLY FLOW INCREASES OUT AHEAD OF APPROACHING SYSTEM...WHICH
WILL SPREAD PRECIPITATION BACK INTO THE REGION FOR SUNDAY. STILL
SOME UNCERTAINTY IN THE EXACT PATH OF THE STORM...BUT AT THIS
POINT...IT LOOKS LIKE A MOSTLY SNOW SCENARIO...ALTHOUGH SOUTHERN
ZONES WILL SEE A PERIOD OF RAIN OR A RAIN SNOW MIX TO START. SEVERAL

THE MODELS SEEM TO BE AT A CROSS ROADS ON HOW TO HANDLE THE WEEKEND

NORTHERN STREAM SHORT DROPPING OVER THIS WESTERN UPPER RIDGE
INTERACTS WITH THE SOUTHERN STREAM SYSTEM. THE LATEST MODEL RUNS
CONTINUE TO DIVERGE. THE 12Z GFS PUTS ALMOST ALL ITS EMPHASIS ON
LEAVING MOST OF THE SOUTHWESTERN UPPER LOW ENERGY IN PLACE AND
DRIVING THE NORTHERN STREAM SHORT WAVE AND COLD FRONT ACROSS THE
AREA SUNDAY. THE 12Z NAM THRU 84 HOURS HINTS AT THIS ALSO. THE 12Z
CMC STILL WANTS TO PHASE THE TWO STREAMS AND DRIVE A STRONG LOW UP
TOWARD THE GREAT LAKES SUNDAY. THE SREF AND 00Z UKMET/EURO ARE IN
BETWEEN THESE TWO SOLUTIONS. AT THIS POINT...IN COORDINATION WITH
WPC GRAPHICS...CHOSE TO ADJUST TO A SLIGHTLY MORE SOUTHERN

OUT AHEAD OF THE NORTHERN STREAM SYSTEM. THIS SCENARIO HAS THE
SURFACE LOW MOVING ACROSS THE NORTHERN PART OF THE AREA ON

CHANGING TO SNOW ALL AREAS EARLY SUNDAY NIGHT AS THE COLD AIR RUSHES
BACK IN. SNOW SHOWERS WILL CONTINUE INTO AT LEAST MONDAY MORNING
WITH A WRAPAROUND MOISTURE FIELD. SNOW SHOWERS THEN WIND DOWN FROM
WEST TO EAST DURING MONDAY AS HIGH PRESSURE BUILDS IN THRU MID WEEK.

SOME WET BULBING ALOFT...ALSO EXPECT SLEET MIXING IN ACROSS
NORTHERN HALF OF CWA THROUGH MID MORNING. WILL CONTINUE WITH
CURRENT FREEZING RAIN ADVISORY...AND GO WITH SPECIAL WEATHER
STATEMENTS OUTSIDE OF THAT AREA DETAILING POTENTIAL FOR BRIEF
PERIOD OF FREEZING RAIN.

PREVIOUS DISCUSSION...
MODELS SHOWING A BAND OF LIGHT PRECIPITATION MOVING ACROSS THE

SOUTHEAST OHIO WHERE TEMPERATURES WILL BE VERY CLOSE TO FREEZING.
WITH ROAD SURFACE TEMPERATURES READING IN THE MID 20S...SOME
FREEZING RAIN COULD OCCUR EVEN IT READINGS ARE SLIGHTLY ABOVE
FREEZING. WILL EXPAND THE FREEZING RAIN ADVISORY TO INCLUDE VINTON
AND ATHENS COUNTIES. MES NAM SOUNDING ALSO SHOW SOME CONCERN FOR
BRIEF FREEZING RAIN/DRIZZLE IN POCAHONTAS COUNTY WHEN THIS BAND
ARRIVES EARLY THIS AFTERNOON. WILL HOLD OFF IN THIS AREA DUE TO
TIME OF DAY AND LIMITED DURATION...BUT WILL HAVE TO KEEP AND EYE
ON THE SITUATION.

A COLD FRONT MOVES THROUGH LATE THIS AFTERNOON AND EVENING...BRINGING
MUCH COLDER AIR. IT APPEARS THAT MOST PRECIPITATION WITH THE FRONT
WILL BE POST FRONTAL. RAIN SHOULD CHANGE OVER TO SNOW DURING THE
NIGHT AND START A DECENT UPSLOPE SNOW EVENT.

WILL FALL AS THE DAY PROGRESSES...INTO THE LOW TO MID 20S OUTSIDE OF
THE MOUNTAINS...AND TEENS IN THE MOUNTAINS. WINDS WILL BE
GUSTY...ESPECIALLY OVER THE HIGH TERRAIN WHERE SOME 30 TO 35 KT
GUSTS WILL BE REALIZED. AS SUCH...WIND CHILLS WILL ALSO TAKE A HIT
BUT NOT EXPECTING CRITERIA TO BE MET OVER THE N MOUNTAINS.

AS FOR SNOW...DESPITE A SHRINKING MOISTURE COLUMN...CAA WILL ALLOW
FOR A COLDER CLOUD LAYER AS THE MORNING PROGRESSES. SOUNDINGS BEAR
THIS OUT WITH SHRINKING CLOUD LAYER COOLING TO -15 TO -20C IN THE
MORNING. THIS COMBINED WITH SOME LOW LEVEL INSTABILITY SHOULD ALLOW
FOR CONVECTIVE OVERTURNING SNOW SHOWERS ACROSS THE AREA. STREAMLINE
ANALYSIS SUGGEST SOME ENHANCEMENT FROM LAKE MICHIGAN EARLY ACROSS S
OH AND NE KY. MODELS ARE NOT EXCITED ABOUT QPF POTENTIAL
THOUGH...NONETHELESS...FELT PRUDENT IN GOING DETERMINISTICALLY HIGH
WITH POPS IN THE MORNING. WITH RATIOS QUICKLY DROPPING INTO THE -20

MOUNTAINS. SINCE THERE WILL BE SOME BLOWING AND DRIFTING OF SNOW TO
COMPOUND THINGS...FELT BEST WAY TO GO WAS WITH AN ADVISORY WHICH
MATCHES WILL WITH SURROUNDING OFFICES.

THE MOISTURE COLUMN SHOULD BECOME SUFFICIENTLY SHALLOW ENOUGH TO
ALLOW A FAIR AMOUNT OF BREAKS IN THE CLOUDS ACROSS THE W AND S
ZONES. HARD TO SAY IF N MOUNTAINS CLEAR OUT FRIDAY NIGHT GIVEN THE
THERMAL TROF GETTING PINCHED OFF. DO THINK SOME CLEARING WILL WORK
ITS WAY THRU REMAINDER OF CWA WITH A COLD NIGHT IN STORE WITH WINDS
SLACKENING OUTSIDE OF THE MOUNTAINS AS A SURFACE HIGH BUILDS IN FROM
THE W. SATURDAY WILL FEATURE MORE STRATOCU ACROSS SE OH AND N

GENERALLY IN THE 30S...WITH SOME 20S IN THE N MOUNTAINS.

STORMS AND RUMORS OF STORMS CONTINUE FOR SUNDAY/MONDAY. THERE
CONTINUES TO BE VOLATILITY IN THE OPERATIONAL GLOBAL MODELS
REGARDING HOW MUCH PHASING OCCURS WITH N STREAM ENERGY AND ENERGY
EJECTING OUT OF SW CONUS. AS HPC NOTED...UNTIL THE N STREAM ENERGY
CAN GET INTO W CANADA...SUSPECT WAFFLING TO CONTINUE WITH JUST HOW
STRONG OF A WAVE/LOW PRESSURE THERE WILL BE. THE ENSEMBLES DONT
OFFER MUCH HELP WITH LARGE SPREADS OVER THE OH VALLEY ON THE GFS
ENSEMBLES. ALL OF THIS UNCERTAINTY RESULTED IN LITTLE CHANGE IN
PREVIOUS FORECAST EXCEPT TO GO A HAIR COOLER ACROSS THE AREA ON

NIGHT INTO FRIDAY NORTHEAST MOUNTAINS.  HIGH PRESSURE SATURDAY.

&&

.NEAR TERM /THROUGH TODAY/...
915 PM UPDATE...
A THINNER OVERCAST THAN PREVIOUSLY EXPECTED IS/WILL ALLOW
TEMPERATURES TO GET LOWER OVERNIGHT...USED MOSTLY THE LAV AND
CURRENT TRENDS TO MAKE ADJUSTMENTS.

THESE SMALL DOWNWARD ADJUSTMENTS IN THE MIDDLE OHIO VALLEY INTO THU
MORNING...AND MAINTAINING THE ARRIVAL OF PRECIPITATION BY MID
MORNING...IS JUST ENOUGH TO WARRANT A FREEZING RAIN ADVISORY FOR
PERRY AND MORGAN COUNTIES IN SE OHIO.  THE 21Z SREF ALSO NOW SHOWS
THIS POTENTIAL STARTING TO EDGE INTO THESE COUNTIES.

THANKS TO PBZ AND ILN FOR COORD ON THIS.

700 PM UPDATE...
FCST ON TRACK BUT WITH ONSET OF PRECIPITATION MEASURABLE OR NOT VERY
CLOSE TO WHEN TEMPERATURES CLIMB ABOVE FREEZING IN SE OHIO AFTER
DAYBREAK THU MORNING.  THE 15Z SREF SUGGESTS THE FREEZING RAIN
SCOOTS JUST TO THE NW OF PERRY CO.

PREV DISCN...
STRATUS DECK FINALLY BREAKING UP ACROSS THE WESTERN SLOPES...BUT
STILL A CHILLY DAY. HIGH CLOUDS BEGIN INCREASING LATE TODAY AND
TONIGHT IN ADVANCE OF LOW PRESSURE MOVING THROUGH THE PLAINS. HAVE
WARM FRONT MOVING THROUGH THURSDAY. INITIALLY...LOW LEVELS ARE
VERY DRY SO ANTICIPATE LOTS OF VIRGA TO START. WITH THE DRY LOW
LEVELS...WILL ALSO SEE SOME WET BULBING AND IN NW PART OF CWA
COULD SEE BRIEF SLEET AT THE ONSET OF PRECIP. HAVE A SMALL AMOUNT
OF FREEZING RAIN IN PERRY AND MORGAN COUNTIES...BUT WITH THE WET
BULBING THIS COULD JUST AS EASILY BE SLEET. ACROSS THE
LOWLANDS...ANY PRECIP WILL CHANGE TO RAIN BY MID MORNING.
SNOW/SLEET WILL LINGER AT THE HIGHEST ELEVATIONS OF THE WV MOUNTAINS
THROUGH MUCH OF THE DAY...WITH SOME LIGHT ACCUMULATIONS. SLOWED DOWN
ONSET OF PRECIPITATION WHEN COMPARED TO PREVIOUS FORECAST AS NEW GFS
AND NAM ARE BOTH SLOWER. DID NOT GO QUITE AS SLOW AS THE MODELS AS
WARM AIR ADVECTION PRECIP OFTEN SEEMS TO ARRIVE SOONER THAN EXPECTED.

AS WARM AIR ADVECTION BEGINS ALOFT TONIGHT...HAVE NON DIURNAL
TREND FOR HIGHER ELEVATIONS. EVEN BEGIN WARMING SOME PRE-DAWN IN
SE OHIO AS 925MB TEMPS CLIMB TO AROUND 5C IN KHTS AREA BY 09Z. IT
MAY TAKE A LITTLE WHILE FOR THE INVERSION TO BREAK...SO TIMING OF
THE WARM-UP IS UNCERTAIN...BUT IT SHOULD BE QUICK ONCE IT HAPPENS.
SPENDING MUCH OF THE DAY IN THE WARM SECTOR WILL PROVIDE A NICE
WARM-UP WITH TEMPS INTO THE 40S ACROSS THE LOWLANDS...AND EVEN
ABOVE FREEZING FOR MANY MOUNTAIN LOCATIONS.

&&

.SHORT TERM /TONIGHT THROUGH SATURDAY/...
WILL SEE A GRADUAL CHANGE OVER TO SNOW THURSDAY NIGHT AS COLDER
AIR RUSHES INTO THE REGION AS CLIPPER TYPE SYSTEM MOVES THROUGH
THE AREA. ALONG WITH THE COLDER AIR...WILL SEE A GRADUAL LOSS OF
MOISTURE...SO ONLY EXPECTING LIGHT ACCUMULATIONS ACROSS THE
LOWLANDS...WITH BETTER SNOWFALL ACCUMULATIONS IN FAVORED UPSLOPE
AREAS...ESPECIALLY AS SNOW RATIOS INCREASE IN THE COLDER AIR.
STILL FIGURING ON SEVERAL INCHES OF ACCUMULATIONS ACROSS THE
NORTHERN MOUNTAIN ZONES...BUT AT THIS POINT...AM NOT GETTING
ADVISORY CRITERIA. HOWEVER...WILL MAINTAIN THE MENTION IN THE HWO
IN CASE THE FORECAST CHANGES.

TEMPERATURES WILL FALL THROUGHOUT THE DAY ON FRIDAY. IN
ADDITION...GUSTY WINDS WILL DEVELOP...CREATING WIND CHILLS IN THE
SINGLE DIGITS TO TEENS. RANDOLPH AND POCAHONTAS COUNTIES WILL SEE
WIND CHILL ADVISORY CRITERIA ALONG RIDGE TOPS...BUT AT THIS
POINT...DO NOT SEE COUNTY AVERAGE.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
THE MODELS SEEM TO BE AT A CROSS ROADS ON HOW TO HANDLE THE WEEKEND
SYSTEM. MODELS AGREE IN A PACIFIC SYSTEM CUTTING UNDER THE HIGH
AMPLITUDE WESTERN U.S. UPPER RIDGE AND CLOSING OFF OVER THE
SOUTHWESTERN STATES EARLY IN THE WEEKEND. THE BIG QUESTION IS HOW A
NORTHERN STREAM SHORT DROPPING OVER THIS WESTERN UPPER RIDGE
INTERACTS WITH THE SOUTHERN STREAM SYSTEM. THE LATEST MODEL RUNS
CONTINUE TO DIVERGE. THE 12Z GFS PUTS ALMOST ALL ITS EMPHASIS ON
LEAVING MOST OF THE SOUTHWESTERN UPPER LOW ENERGY IN PLACE AND
DRIVING THE NORTHERN STREAM SHORT WAVE AND COLD FRONT ACROSS THE
AREA SUNDAY. THE 12Z NAM THRU 84 HOURS HINTS AT THIS ALSO. THE 12Z
CMC STILL WANTS TO PHASE THE TWO STREAMS AND DRIVE A STRONG LOW UP
TOWARD THE GREAT LAKES SUNDAY. THE SREF AND 00Z UKMET/EURO ARE IN
BETWEEN THESE TWO SOLUTIONS. AT THIS POINT...IN COORDINATION WITH
WPC GRAPHICS...CHOSE TO ADJUST TO A SLIGHTLY MORE SOUTHERN
TRACK...WHICH STILL CARRIES A DECENT CHUNK OF SOUTHERN ENERGY JUST
OUT AHEAD OF THE NORTHERN STREAM SYSTEM. THIS SCENARIO HAS THE
SURFACE LOW MOVING ACROSS THE NORTHERN PART OF THE AREA ON
SUNDAY...THEN DRIVING A COLD FRONT RAPIDLY ACROSS THE AREA EARLY
SUNDAY NIGHT. SO...SENSIBLE WEATHER INCLUDES INITIALLY WINTRY
PRECIPITATION EARLY SUNDAY...THEN CHANGING TO RAIN DURING SUNDAY
CENTRAL AND SOUTH...AND KEEPING AT LEAST A MIX ACROSS SOUTHEAST OHIO
AND NORTHERN WEST VIRGINIA NEAR THE TRACK OF THE LOW...THEN RAPIDLY
CHANGING TO SNOW ALL AREAS EARLY SUNDAY NIGHT AS THE COLD AIR RUSHES
BACK IN. SNOW SHOWERS WILL CONTINUE INTO AT LEAST MONDAY MORNING
WITH A WRAPAROUND MOISTURE FIELD. SNOW SHOWERS THEN WIND DOWN FROM
WEST TO EAST DURING MONDAY AS HIGH PRESSURE BUILDS IN THRU MID WEEK.
THERE WILL LIKELY BE SOME SNOW ACCUMULATION ACROSS THE AREA SUNDAY
INTO MONDAY....ESPECIALLY IN THE MOUNTAINS. EXCEPT FOR THE BRIEF
WARMUP SUNDAY...TEMPERATURES WILL AVERAGE WELL BELOW NORMAL FOR THE
PERIOD.

&&

.AVIATION /06Z THURSDAY THROUGH MONDAY/...
CLOUDS WILL BE LOWERING THIS MORNING BUT SHOULD SHOULD REMAIN VFR. A
BAND OF SHOWERS WILL MOVE ACROSS THE AREA FROM LATE MORNING TO MID
AFTERNOON. RESTRICTIONS WITH THIS BAND ARE EXPECTED TO BE VFR OR
BRIEFLY MVFR.

A COLD FRONT WILL THEN MOVE THROUGH THIS AFTERNOON AND EVENING. MVFR
RESTRICTIONS IN CLOUDS CAN BE EXPECTED ALONG AND BEHIND THE COLD
FRONT. AS COLDER AIR MOVES IN THURSDAY NIGHT...SNOW WILL DEVELOP
CAUSING SIGNIFICANT RESTRICTIONS IN VISIBILITIES AND CEILINGS.
