AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
647 PM MDT THU MAY 28 2015

.SYNOPSIS...AN UPPER LOW OVER THE NORTHERN ROCKIES WILL MOVE EAST
INTO THE PLAINS STATES TOMORROW. HIGH PRESSURE WILL STRENGTHEN
ACROSS THE REGION THIS WEEKEND...RESULTING IN A SUBSTANTIAL
WARMING AND DRYING TREND.


&&

.SHORT TERM...HAVE UPDATED THE FORECAST FOR THIS EVENING AS
SHOWERS AND THUNDERSTORMS HAVE DIMINISHED RAPIDLY LATE THIS
AFTERNOON AND EARLY EVENING ACROSS THE NORTH. THIS DUE TO LOWER
SUN ANGLE AND THE COLD POOL ALOFT MOVING EAST RESULTING IN AN AIR
MASS THAT IS QUICKLY STABILIZING. THE SOUTHERN AND CENTRAL PORTIONOF
THE CWA WILL STILL HAVE ISOLATED TO SCATTERED MOUNTAIN SHOWERS AND
THUNDERSTORMS FOR A COUPLE OF MORE HOURS AS THEY ARE BEING DRIVEN
BUT THE REMNANTS OF A MID LEVEL BOUNDARY THAT MOVED ACROSS
NORTHERN UTAH EARLIER IN THE DAY AND NOW IS REACHING THE CENTRAL
REGION OF THE STATE. THESE WILL DIE OFF THIS EVENING AND THEREFORE
HAVE REMOVED ALL CHANCES OF SHOWERS AND THUNDERSTORMS FOR THE
LATER HALF OF THE NIGHT.

SKIES HAVE ALSO CLEARED OFF ACROSS THE NORTHWEST PORTION OF UTAH
AND DISSIPATED SUBSTANTIALLY OVER THE REST OF NORTHERN UTAH AND
SOUTHWEST WYOMING IN PAST HOUR.


&&

.AVIATION...WINDS SHOULD REMAIN OUT OF THE NORTHWEST AT THE SLC
TERMINAL THROUGH AT LEAST 03Z...WITH A 40 PERCENT CHANCE OF
REMAINING NORTH THROUGH 05Z. NO OTHER WEATHER CONCERNS FOR THE SLC
TERMINAL TONIGHT.

&&

.FIRE WEATHER...FAIRLY SIMILAR TEMPERATURE/HUMIDITY FOR THE
REST OF TODAY COMPARED TO YESTERDAY. IT IS ONCE AGAIN SOMEWHAT
COOL/MOIST ACROSS THE NORTH...AND DRY AND WARM ACROSS THE SOUTH.
AFTERNOON AND EVENING THUNDERSTORMS HOWEVER SHOULD CONTINUE TO BE
MORE EVENLY DISTRIBUTED ACROSS THE STATE. THE STRONGEST ACTIVITY
WILL BRING A CHANCE FOR CLOUD TO GROUND LIGHTNING...BRIEF HEAVY
RAIN...SMALL HAIL...AND GUSTY/ERRATIC WINDS.

THE PATTERN SHIFTS TOMORROW THROUGH THE WEEKEND AS A RIDGE BUILDS
IN. EXPECT VERY WARM CONDITIONS AND A DRYING TREND ACROSS ALL OF
UTAH. THE CHANCE FOR AFTERNOON SHOWERS AND THUNDERSTORMS WILL THIN
EACH DAY AND BE RELEGATED TO THE MOUNTAINS FOR THE MOST PART.
SOUTHERLY WINDS WILL BECOME GUSTY SUNDAY...INCREASING THROUGH
TUESDAY...WITH A STRONG LIKELIHOOD OF SEEING CRITICAL METEOROLOGICAL
FIRE WEATHER CONDITIONS SUNDAY INTO EARLY NEXT WEEK.

COOLING AND MOISTENING CONDITIONS DEVELOP ACROSS THE NORTH BY MID
WEEK BEHIND THE NEXT COOL FRONT. SHOWERS SHOULD INCREASE IN COVERAGE
AGAIN YET SHOULD NOT BE AS WIDESPREAD AS THE LAST COUPLE OF WEEKS.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...NONE.
WY...NONE.

.SYNOPSIS...AN UPPER LOW OVER THE NORTHERN ROCKIES WILL MOVE EAST
INTO THE PLAINS STATES TOMORROW. HIGH PRESSURE WILL STRENGTHEN
ACROSS THE REGION THIS WEEKEND...RESULTING IN A SUBSTANTIAL
WARMING AND DRYING TREND.

&&

.SHORT TERM (THROUGH 06Z MONDAY)...
A TROUGH CROSSING WYOMING INTO COLORADO WILL CONTINUE TO PROVIDE
DYNAMIC LIFT ACROSS THE CWA INTO THE EVENING. DEEP LAYER SHEAR
NEAR 40KTS SHOULD KEEP THE THREAT OF ORGANIZED CONVECTION INTO THE
EVENING. ONCE THE SUN GOES DOWN...SHOULD SEE A DRAMATIC DECREASE
IN AREAL COVERAGE. MAIN THREATS WILL CONTINUE TO BE SMALL
HAIL...GUSTY WINDS AND BRIEF HEAVY RAINFALL.

ANOTHER ROUND OF CONVECTION IS POSSIBLE ACROSS MAINLY THE SOUTHERN
MOUTAINS AND THE WESTERN UINTA MOUNTAINS FRIDAY AFTERNOON/EVENING.
WITH LESS SHEAR...EXPECT MAINLY TERRAIN FORCED CONVECTION.

AFTER FRIDAY...FINALLY...AN UPPER LEVEL RIDGE WILL BUILD ACROSS THE
AREA THROUGH THE WEEKEND. THE WARMEST TEMPERATURES OF THE YEAR ARE
FORECAST FOR MUCH OF UTAH...WITH SALT LAKE CITY EXPECTED TO REACH
THE UPPER 80S BY SUNDAY.

.LONG TERM (AFTER 06Z MONDAY)...
SIGNIFICANT WARMING AND DRYING TREND CONTINUES MONDAY. STORM
COVERAGE WILL CONTINUE TO THIN OUT AND BECOME RELEGATED TO THE
MOUNTAINS.

GUSTY SOUTHERLY WINDS CONTINUE THROUGH EARLY NEXT WEEK AS THE RIDGE
SHIFTS EAST OF THE ROCKIES. BY MIDWEEK THE NEXT CLOSED LOW TRAVERSES
THE NORTHERN ROCKIES...INCREASING SHOWER/THUNDERSTORM COVERAGE
ACROSS THE NORTH. EXPECTING TEMPERATURES TO COOL TO OR JUST BELOW
NORMAL WITH THE PASSAGE OF A COOL FRONT BY MIDWEEK.

&&

.AVIATION...THERE IS A 30 PERCENT CHANCE OF THUNDERSTORMS IMPACTING
THE SLC TERMINAL BETWEEN 21Z AND 00Z...WITH GUSTY ERRATIC WINDS AND
BRIEF MVFR VISIBILITIES IN HEAVY RAIN AS THE MOST LIKELY IMPACTS.
OTHERWISE...WINDS SHOULD REMAIN OUT OF THE NORTHWEST THROUGH AT

IN. EXPECT VERY WARM CONDITIONS AND A DRYING TREND ACROSS ALL OF
UTAH. THE CHANCE FOR AFTERNOON SHOWERS AND THUNDERSTORMS WILL THIN
EACH DAY AND BE RELEGATED TO THE MOUNTAINS FOR THE MOST PART.
SOUTHERLY WINDS WILL BECOME GUSTY SUNDAY...INCREASING THROUGH

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
238 PM MDT THU MAY 28 2015

.SYNOPSIS...AN UPPER LOW OVER THE NORTHERN ROCKIES WILL MOVE EAST
INTO THE PLAINS STATES TOMORROW. HIGH PRESSURE WILL STRENGTHEN
ACROSS THE REGION THIS WEEKEND...RESULTING IN A SUBSTANTIAL
WARMING AND DRYING TREND.

&&

.SHORT TERM (THROUGH 06Z MONDAY)...
A TROUGH CROSSING WYOMING INTO COLORADO WILL CONTINUE TO PROVIDE
DYNAMIC LIFT ACROSS THE CWA INTO THE EVENING. DEEP LAYER SHEAR
NEAR 40KTS SHOULD KEEP THE THREAT OF ORGANIZED CONVECTION INTO THE
EVENING. ONCE THE SUN GOES DOWN...SHOULD SEE A DRAMATIC DECREASE
IN AREAL COVERAGE. MAIN THREATS WILL CONTINUE TO BE SMALL
HAIL...GUSTY WINDS AND BRIEF HEAVY RAINFALL.

ANOTHER ROUND OF CONVECTION IS POSSIBLE ACROSS MAINLY THE SOUTHERN
MOUTAINS AND THE WESTERN UINTA MOUNTAINS FRIDAY AFTERNOON/EVENING.
WITH LESS SHEAR...EXPECT MAINLY TERRAIN FORCED CONVECTION.

AFTER FRIDAY...FINALLY...AN UPPER LEVEL RIDGE WILL BUILD ACROSS THE
AREA THROUGH THE WEEKEND. THE WARMEST TEMPERATURES OF THE YEAR ARE
FORECAST FOR MUCH OF UTAH...WITH SALT LAKE CITY EXPECTED TO REACH
THE UPPER 80S BY SUNDAY.

.LONG TERM (AFTER 06Z MONDAY)...
SIGNIFICANT WARMING AND DRYING TREND CONTINUES MONDAY. STORM
COVERAGE WILL CONTINUE TO THIN OUT AND BECOME RELEGATED TO THE
MOUNTAINS.

GUSTY SOUTHERLY WINDS CONTINUE THROUGH EARLY NEXT WEEK AS THE RIDGE
SHIFTS EAST OF THE ROCKIES. BY MIDWEEK THE NEXT CLOSED LOW TRAVERSES
THE NORTHERN ROCKIES...INCREASING SHOWER/THUNDERSTORM COVERAGE
ACROSS THE NORTH. EXPECTING TEMPERATURES TO COOL TO OR JUST BELOW
NORMAL WITH THE PASSAGE OF A COOL FRONT BY MIDWEEK.

&&

.AVIATION...THERE IS A 30 PERCENT CHANCE OF THUNDERSTORMS IMPACTING
THE SLC TERMINAL BETWEEN 21Z AND 00Z...WITH GUSTY ERRATIC WINDS AND
BRIEF MVFR VISIBILITIES IN HEAVY RAIN AS THE MOST LIKELY IMPACTS.
OTHERWISE...WINDS SHOULD REMAIN OUT OF THE NORTHWEST THROUGH AT
LEAST 02Z...BEFORE SWITCHING BACK TO THE SOUTHEAST BETWEEN 03Z AND
05Z.

&&

.FIRE WEATHER...FAIRLY SIMILAR TEMPERATURE/HUMIDITY FOR THE
REST OF TODAY COMPARED TO YESTERDAY. IT IS ONCE AGAIN SOMEWHAT
COOL/MOIST ACROSS THE NORTH...AND DRY AND WARM ACROSS THE SOUTH.
AFTERNOON AND EVENING THUNDERSTORMS HOWEVER SHOULD CONTINUE TO BE
MORE EVENLY DISTRIBUTED ACROSS THE STATE. THE STRONGEST ACTIVITY
WILL BRING A CHANCE FOR CLOUD TO GROUND LIGHTNING...BRIEF HEAVY
RAIN...SMALL HAIL...AND GUSTY/ERRATIC WINDS.

THE PATTERN SHIFTS TOMORROW THROUGH THE WEEKEND AS A RIDGE BUILDS
IN. EXPECT VERY WARM CONDITIONS AND A DRYING TREND ACROSS ALL OF
UTAH. THE CHANCE FOR AFTERNOON SHOWERS AND THUNDERSTORMS WILL THIN
EACH DAY AND BE RELEGATED TO THE MOUNTAINS FOR THE MOST PART.
SOUTHERLY WINDS WILL BECOME GUSTY SUNDAY...INCREASING THROUGH
TUESDAY...WITH A STRONG LIKELIHOOD OF SEEING CRITICAL METEOROLOGICAL

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1123 AM MDT THU MAY 28 2015

.SYNOPSIS...AN UPPER LOW OVER THE NORTHERN ROCKIES WILL MOVE EAST
INTO THE PLAINS STATES BY FRIDAY. HIGH PRESSURE WILL STRENGTHEN
ACROSS THE REGION THIS WEEKEND...RESULTING IN A SUBSTANTIAL
WARMING AND DRYING TREND.

&&

.DISCUSSION...A SLOW MOVING TROUGH WILL CROSS IDAHO INTO WYOMING
TODAY. AHEAD OF THIS TROUGH...SUFFICIENT DYNAMIC LIFT SHOULD
OCCUR ACROSS MUCH OF THE CWA SUPPORTING FAIRLY WIDESPREAD
CONVECTION.

THE MAIN QUESTION IS TO HOW ORGANIZED THIS CONVECTION WILL BE
THROUGH THE AFTERNOON AND EVENING. SREF ENSEMBLE DATA INDICATES
THE MAIN STUMBLING POINT WILL BE THE AMOUNT OF INSTABILITYAVAILABLE...AS
MUCAPE VALUES REMAIN AT OR BELOW 500 J/KG ACROSS MUCH OF CENTRAL
AND SOUTHERN UTAH.

THE CWA WILL NOT BE LACKING FOR DEEP LAYER SHEAR. MORNING
MESOANALYSIS INDICATES 0-6KM BULK SHEAR VALUES NEARING 45-50KTS
ACROSS MUCH OF THE STATE OF UTAH. EXPECT WITH THIS AMOUNT OF DEEP
LAYER SHEAR THAT LACK OF INSTABILITY MAY BE OVERCOME. THE HRRR HAS
BEEN QUITE INSISTENT WITH TWO FOCUSES OF CONVECTION THIS
AFTERNOON/EVENING...ALONG THE UTAH/IDAHO BORDER THROUGH UINTA
COUNTY WYOMING AND ACROSS THE SOUTHERN HALF OF UTAH. THIS MATCHES
WITH WHAT ONE WOULD EXPECT BASED ON SUBJECTIVE ANALYSIS.

LOOKING AT THE 12Z SLC SOUNDING...EXPECT THE THREAT OF STRONG
WINDS IS LOWER THAN NORMAL GIVEN HOW MOIST THE ENVIRONMENT
REMAINS. THE MAIN THREATS WITH ANY ORGANIZED STORMS WILL BE HAIL
AND HEAVY RAIN. EVEN WITH THE RELATIVELY MOIST ENVIRONMENT...GUSTY
WINDS ARE ALWAYS A THREAT...PARTICULARLY WITH COLLAPSING STORMS.

UPDATED THE FORECAST TO MAINLY TO INCREASE POPS ACROSS THE SOUTH
AFTER 00Z. NO ADDITIONAL UPDATES ARE ANTICIPATED AT THIS TIME.

SALT LAKE CITY AIRPORT BROKE THE RECORD FOR NUMBER OF DAYS WITH
MEASURABLE PRECIPITATION FOR THE MONTH OF MAY. THIS MONTH IS ALSO
RANKED FIFTH FOR THE NUMBER OF DAYS OF MEASURABLE PRECIPITATION
FOR ANY MONTH SINCE 1874.

&&

.AVIATION...SOUTHEAST WINDS AT THE SLC TERMINAL ARE EXPECTED
TO SWITCH TO NORTHWEST BETWEEN 17-19Z. OPERATIONAL WEATHER CONCERNS
WILL FOCUS ON PERIODIC SHOWERS AFTER ABOUT 19Z...WITH A 20 PERCENT
CHANCE OF THUNDERSTORMS THROUGH 23Z. PRIMARY IMPACTS FROM PASSING
SHOWERS/STORMS WILL BE A BRIEF REDUCTION OF CIGS TO AOB 6000FT
AGL...GUSTY ERRATIC WINDS AND LIGHTNING IN THE VICINITY OF THE
AIRFIELD.

&&

.FIRE WEATHER...EXPECTING FAIRLY SIMILAR TEMPERATURE/HUMIDITY TODAY
COMPARED TO YESTERDAY. IT WILL ONCE AGAIN BE SOMEWHAT COOL/MOIST
ACROSS THE NORTH...AND DRY AND WARM ACROSS THE SOUTH. AFTERNOON AND
EVENING THUNDERSTORMS HOWEVER SHOULD BE MORE EVENLY DISTRIBUTED
ACROSS THE STATE. THE STRONGEST ACTIVITY WILL BRING A CHANCE FOR

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
423 AM MDT THU MAY 28 2015

.SYNOPSIS...AN UPPER LOW OVER THE NORTHERN ROCKIES WILL MOVE EAST
INTO THE PLAINS STATES BY FRIDAY. HIGH PRESSURE ALOFT WILL
STRENGTHEN ACROSS THE REGION THIS WEEKEND...RESULTING IN A
SUBSTANTIAL WARMING AND DRYING TREND.

&&

.SHORT TERM (THROUGH 06Z MONDAY)...THE UPPER LOW CURRENTLY
POSITIONED ACROSS SOUTHWEST MONTANA/EASTERN IDAHO WILL BECOME AN
OPEN TROUGH AND WEAKEN AS IT HEADS FOR THE NORTHERN/CENTRAL PLAINS
STATES FRIDAY.

LOOKING AT ANOTHER DAY OF ACTIVE CONVECTION AS AT LEAST DYNAMIC
FEATURES ROTATE EAST THROUGH THE REGION. THE FIRST SYSTEM ROTATING
EAST THROUGH NORTHWEST UTAH AT TIME IS PRODUCING A LINE OF
SHOWERS/STORMS ACROSS THE SALT FLATS. THE LEFT EXIT REGION OF THE
JET STREAK OVER NORTHWEST UTAH COULD SUPPORT THIS CONVECTION AS IT
MOVES INTO THE NORTHERN/CENTRAL URBAN CORRIDOR AROUND SUNRISE.

SUBSIDENCE BEHIND THIS FIRST SHORTWAVE WILL BE SHORT-LIVED AS THE
SECOND SHORTWAVE CURRENTLY MOVING SOUTH ALONG THE WESTERN FLANK
OF THE UPPER LOW WILL TURN EAST ACROSS NORTHERN/CENTRAL UTAH AND
SOUTHWEST WYOMING LATE THIS MORNING THROUGH THIS AFTERNOON. THE
STRUCTURE OF THIS SECOND FEATURE LOOKS GOOD FOR DEEP CONVECTION...
ESPECIALLY DURING THE LATE MORNING AND AFTERNOON HOURS. MID-LEVEL
COOLING ASSOCIATED WITH THE UPPER LOW TO DESTABILIZE THE AIR MASS
ALONG WITH INCREASING DYNAMIC LIFT AND THE STILL PRESENT JET
SUPPORT SHOULD ALLOW CONVECTION TO DEVELOP AGAIN DURING THE LATE
MORNING/EARLY AFTERNOON HOURS. INCREASING 700-400MB SHEAR DURING
THE AFTERNOON COULD SUPPORT STRONG CONVECTION ACROSS MAINLY
CENTRAL UTAH DURING THE MID TO LATE AFTERNOON HOURS.

SHOWERS AND ISOLATED THUNDERSTORMS WILL LINGER TONIGHT...WITH THIS
ACTIVITY CONFINED MAINLY ACROSS NORTHEAST THROUGH SOUTHWEST UTAH.
HIGH PRESSURE ALOFT WILL BEGIN TO BUILD INTO THE WESTERN GREAT
BASIN TONIGHT...THEN EXPAND EAST ACROSS UTAH FOR FRIDAY THROUGH
THE UPCOMING WEEKEND. THIS BUILDING RIDGE WILL START A DRYING AND
WARMING TREND...WITH TEMPERATURES ENDING UP ABOVE NORMAL AREA WIDE
THROUGH THE WEEKEND.

.LONG TERM (AFTER 06Z MONDAY)...PRIMARY FOCUS IN THE LONG TERM
FORECAST CONTINUES TO BE THE MARKED WARMING/DRYING TREND THAT WILL
CONTINUE INTO EARLY NEXT WEEK. GUIDANCE CONTINUES TO TREND H7 TEMPS
SLIGHTLY WARMER SUN-MON WITH VALUES NOW PUSHING +14 C AT KSLC.
ENCROACHMENT OF YET ANOTHER PACIFIC TROUGH INTO THE WESTERN CONUS
WILL STRENGTHEN MID LEVEL SOUTHWESTERLY FLOW...AND NET DRYING AT THE
LOW LEVELS WILL PROMOTE DEEP MIXING OF THIS AIRMASS EACH DAY. MADE
MINIMAL CHANGES TO GRIDS OUTSIDE OF UPPING AFTERNOON HIGHS A DEGREE
OR TWO...PRIMARILY ACROSS THE WESTERN VALLEYS.

AFOREMENTIONED TROUGH WILL PRIMARILY REMAIN TO THE NORTH AND WEST OF
THE AREA EARLY/MID NEXT WEEK...THOUGH EJECTING LOBES WITHIN A
CYCLONIC SOUTHWESTERLY FLOW WILL LIKELY CLIP FAR WESTERN/NORTHERN
UTAH DURING THE PERIOD. RESULTANT LOWERING OF HEIGHTS COMBINED WITH
WEAK CAA FROM THE NORTHWEST WILL ALLOW FOR SOME COOLING AND A RETURN
TO NEAR NORMAL TEMPS IN THE NORTH...THIS AFTER RUNNING SOME 10
DEGREES ABOVE. MAINTAINED SLIGHT CHANCE POPS FOR THE FAR
NORTHERN/WESTERN AREAS...THOUGH ANY CONVECTION WILL LIKELY BE
LIMITED TO THE HIGH BASED AND GUSTY WIND VARIETY WITH MINIMAL PRECIP
EXPECTED.

&&

.FIRE WEATHER...AN UPPER LOW CURRENTLY OVER CENTRAL IDAHO WILL PASS
ACROSS NORTHERN PORTIONS OF THE DISTRICT TODAY. EXPECTING YET
ANOTHER INCREASE OF SHOWERS AND STORMS BEGINNING MID MORNING AND
CONTINUING THROUGH THE AFTERNOON...WITH FOCUSED WETTING RAIN
POTENTIAL ACROSS THE NORTHERN HALF OF THE DISTRICT. PASSAGE OF THIS
LOW TONIGHT THROUGH TOMORROW WILL ALLOW A NET DRYING TREND TO TAKE
FORM FROM WEST TO EAST.

HIGH PRESSURE WILL EXPAND INTO THEN BUILD ACROSS THE DISTRICT THIS
WEEKEND BRINGING A MARKED DRYING/WARMING TREND TO ALL AREAS.
SOUTHERLY WINDS WILL INCREASE BEGINNING SUNDAY AS YET ANOTHER
PACIFIC LOW TRANSITIONS INTO THE PACIFIC NORTHWEST REGION. NOT
EXPECTING MUCH IN THE WAY OF STORM ACTIVITY FROM THIS OUTSIDE OF
ISOLATED HIGH BASED SHOWERS/STORMS OF THE GUSTY VARIETY ACROSS FAR
NORTHERN PORTIONS EACH AFTERNOON/EVE. BOTTOM LINE...SIGNIFICANTLY
LOWER RH AND STRENGTHENING SOUTHERLY WINDS IN THE SUN-TUE TIMEFRAME.

&&

.AVIATION...OPERATIONAL WEATHER CONCERNS FOR THE KSLC TERMINAL WILL
CONTINUE TO FOCUS ON PERIODIC SHOWERS AND A 20 PERCENT CHANCE OF
THUNDERSTORMS THROUGH THIS AFTERNOON. PRIMARY IMPACTS FROM PASSING
SHOWERS/STORMS WILL BE A BRIEF REDUCTION OF CIGS TO AOB 6000FT

SOUTHWEST UTAH. SHOWERS WITH EMBEDDED THUNDERSTORMS WILL CONTINUE
ALONG THIS AREA FOR THE NEXT FEW HOURS...STRONGEST ACROSS NORTHEAST
UTAH AND SOUTHWEST WYOMING.

A MOIST AIRMASS REMAINS IN PLACE THIS EVENING...ALTHOUGH
INSTABILITY WILL PROGRESSIVELY BECOME LESS WITH THE LOSS OF
DAYTIME HEATING. HOWEVER...LARGE SCALE LIFT AHEAD OF THE LOW ALONG
WITH A WEAK EMBEDDED SHORTWAVE DISTURBANCE IS CURRENTLY FIRING UP
A FEW THUNDERSTORMS ACROSS FAR NORTHEAST NEVADA AND NORTHWEST
UTAH. THESE STORMS ARE EXPECTED TO CONTINUE ACROSS PORTIONS OF
NORTHERN UTAH OVERNIGHT...THOUGH NOT WITH NEARLY THE STRENGTH OR
COVERAGE SEEN EARLIER.

THE LOW WILL OPEN INTO A TROUGH AND GRAZE NORTHERN UTAH TOMORROW
BEFORE EXITING THE AREA TOMORROW EVENING. STILL ENOUGH SHEAR TO
MAINTAIN A FEW STRONG THUNDERSTORMS TOMORROW...WITH THINGS THEN
WINDING DOWN FAIRLY QUICKLY TOMORROW EVENING.

UPDATED THE FORECAST MAINLY TO ADJUST POPS FOR THE REMAINDER OF
THE NIGHT.

&&

.AVIATION...SOUTHEAST WINDS ARE EXPECTED TO PREVAIL AT THE SLC
TERMINAL BY 05Z. ANOTHER ROUND OF SHOWERS ARE POSSIBLE...ARRIVING
AROUND 07-08Z...WHICH COULD BRING A PERIOD WITH CIGS NEAR OR
BELOW 6000FT AGL AND A 10 PERCENT CHANCE OF MVFR CONDITIONS.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
407 PM MDT WED MAY 27 2015

.SYNOPSIS...AN UPPER LOW MOVING OUT OF THE PACIFIC NORTHWEST WILL
IMPACT MUCH OF UTAH THROUGH THURSDAY. HIGH PRESSURE WILL
STRENGTHEN ACROSS THE REGION LATE IN THE WEEK THROUGH THE UPCOMING
WEEKEND RESULTING IN A WARMING AND DRYING TREND.



&&

.SHORT TERM (THROUGH 06Z SUNDAY)...AN UPPER LOW PRESSURE SYSTEM IS
SPINNING OVER IDAHO THIS AFTERNOON...WITH THE SOUTHERN PORTIONS OF
THE TROUGH IMPACTING UTAH AND SOUTHWEST WYOMING. THIS TROUGH HAS
HELPED INITIATE THUNDERSTORMS ACROSS THE NORTHERN TWO THIRDS OF
THE FORECAST AREA...WITH SOME OF THESE STORMS BECOMING
SEVERE. LARGE HAIL HAS BEEN REPORTED...AS WELL AS A COUPLE FUNNEL
CLOUD REPORTS NEAR THE UINTA BASIN. EFFECTIVE BULK SHEAR IS NOT
ALL THAT IMPRESSIVE...GENERALLY 20-25 KNOTS...BUT SOME OF THE
STRONGER CELLS HAVE BEEN IN AREAS WITH SMALL ANALYZED POCKETS OF
30-40 KNOTS OF SHEAR.

GOOD INSTABILITY WILL LIKELY PERSIST INTO THE EVENING
HOURS...WITH SOME STRONGER CELLS LIKELY TO MOVE INTO TOOELE AND
BOX ELDER COUNTIES FROM NEVADA. LOWERED POPS A BIT BETWEEN 06Z AND
12Z THURSDAY...AS MOST MODELS HAVE SHOWERS CALMING DOWN DURING THE
OVERNIGHT HOURS...BUT SHOWERS WILL LIKELY INCREASE AGAIN THURSDAY
MORNING ACROSS NORTHERN UTAH AS THE LOW DROPS INTO THE AREA.
SEVERE STORMS COULD BE POSSIBLE AGAIN THURSDAY AFTERNOON AS THE
TROUGH AXIS PASSES THROUGH THE CWA...THOUGH SHOWERS MAY END
EARLIER THAN USUAL WITH THE TROUGH MOVING TO THE EAST SHORTLY
AFTER 00Z FRIDAY.

THE TROUGH FINALLY EXITS THE REGION THROUGH THE DAY FRIDAY...WITH
A SHORTWAVE RIDGE BUILDING OVER THE GREAT BASIN. THIS WILL BEGIN A
WARMING AND DRYING TREND HEADING INTO THE WEEKEND...WITH
TEMPERATURES RISING ABOVE SEASONAL NORMALS BY SATURDAY AFTERNOON.


.LONG TERM (AFTER 06Z SUNDAY)...

SIGNIFICANT WARMING AND DRYING TREND CONTINUES DURING THE SECOND
HALF OF THE WEEKEND INTO EARLY NEXT WEEK WITH THE RIDGE CENTERING
OVERHEAD SUNDAY. STORM COVERAGE WILL CONTINUE TO THIN OUT AND BECOME
RELEGATED TO THE MOUNTAINS.

SOUTHERLY WINDS BECOME GUSTY LATE SUNDAY AFTERNOON THROUGH EARLY
NEXT WEEK AS THE RIDGE SHIFTS EAST OF THE ROCKIES. BY MIDWEEK THE
NEXT CLOSED LOW TRAVERSES THE NORTHERN ROCKIES...INCREASING
SHOWER/THUNDERSTORM COVERAGE ACROSS THE NORTH. EXPECTING
TEMPERATURES TO COOL TO OR JUST BELOW NORMAL WITH THE PASSAGE OF A
COOL FRONT BY MIDWEEK.

&&

.AVIATION...NORTHERLY WINDS ARE EXPECTED TO PREVAIL AT THE
SLC TERMINAL THROUGH ABOUT 03Z THEN SHIFT TO SOUTHEASTERLY. SHOWERS
WILL BE INCREASING IN COVERAGE IN THE AREA THROUGH THE REST OF THIS
AFTERNOON AND INTO THIS EVENING. VFR CONDITIONS WILL PREVAIL BUT
CIGS COULD DIP TO OR BELOW 6000 FT WITH PASSING SHOWERS AND GUSTY
ERRATIC WINDS ARE ALSO POSSIBLE. SHOWERS COULD BECOME MORE FREQUENT
AFTER ABOUT 05-06Z WITH PREVAILING CIGS AOB 6000 FT AND BRIEF MVFR
POSSIBLE IN HEAVIER RAIN.

&&

.FIRE WEATHER...THE REST OF TODAY AND TOMORROW WILL BE WARM AND
FAIRLY DRY ACROSS THE SOUTH...WHILE THE NORTH REMAINS COOL AND
MOIST. THE BEST CHANCE FOR A WETTING RAIN IS ALSO ACROSS THE NORTH.
SHOWERS AND STORMS INCREASE IN COVERAGE THROUGH THE REMAINDER OF
THIS AFTERNOON. IT SHOULD REMAIN ACTIVE ACROSS THE NORTH THIS
EVENING...THEN AGAIN TOMORROW AS WELL. THE STRONGEST ACTIVITY WILL
BRING A CHANCE FOR CLOUD TO GROUND LIGHTNING...GUSTY/ERRATIC
WINDS...AND SMALL HAIL.

THE PATTERN SHIFTS FRIDAY THROUGH THE WEEKEND AS A RIDGE BUILDS IN.
EXPECT VERY WARM CONDITIONS AND A DRYING TREND ACROSS ALL OF UTAH.
THE CHANCE FOR AFTERNOON SHOWERS AND THUNDERSTORMS WILL THIN EACH
DAY AND BE RELEGATED TO THE MOUNTAINS FOR THE MOST PART. SOUTHERLY
WINDS WILL BECOME GUSTY SUNDAY...INCREASING THROUGH
TUESDAY...INCREASING THE LIKELIHOOD OF SEEING CRITICAL METEOROLOGICAL
FIRE WEATHER CONDITIONS INTO EARLY NEXT WEEK.

&&

.SYNOPSIS...AN UPPER LOW MOVING OUT OF THE PACIFIC NORTHWEST WILL
IMPACT MUCH OF UTAH THROUGH THURSDAY. HIGH PRESSURE WILL
STRENGTHEN ACROSS THE REGION LATE IN THE WEEK THROUGH THE UPCOMING
WEEKEND RESULTING IN A WARMING AND DRYING TREND.


&&

.DISCUSSION...AN UPPER LOW PRESSURE SYSTEM IS SPINNING OVER IDAHO
THIS MORNING...WITH UTAH AND SOUTHWEST WYOMING CONTINUING TO BE
IMPACTED BY WAVES ON THE SOUTH END OF THIS LOW. ONE SUCH
DISTURBANCE IS MOVING THROUGH NORTHERN UTAH AS OF 1530Z...AND HAS
MAINTAINED A LINE OF SHOWERS WITH ISOLATED THUNDERSTORMS ACROSS
TOOELE AND BOX ELDER COUNTIES FOR THE PAST FEW HOURS. THIS BAND
WILL IMPACT THE WASATCH FRONT AND CACHE VALLEY BETWEEN 1530Z AND
17Z...WITH RAINFALL AND BRIEF GUSTY WINDS MOST LIKELY.

WHILE THERE MAY BE A BRIEF PERIOD OF STABILITY FOLLOWING THIS LINE
OF SHOWERS LATE THIS MORNING...STILL EXPECTING ANOTHER ACTIVE DAY
OF CONVECTION THIS AFTERNOON. SOMEWHAT DRIER AND MORE STABLE AIR
HAS BEGUN MOVING INTO SOUTHERN UTAH...SO THAT AREA MAY NOT BE AS
ACTIVE AS IN PAST DAYS...BUT STILL CANNOT RULE OUT SOME ISOLATED
ACTIVITY...ESPECIALLY COMING OFF THE HIGHER TERRAIN.

THE MOIST AND UNSTABLE CONDITIONS CONTINUE THROUGH TONIGHT AND
THURSDAY...AS THE LOW CONTINUES TO SLIDE SOUTHWARD SLOWLY. THE
FORECAST AREA FINALLY LOOKS TO GET A PERIOD OF DRIER WEATHER
BEGINNING FRIDAY OR SATURDAY...AS THE STORM EXITS TO THE EAST AND
HIGH PRESSURE BUILDS OVER THE GREAT BASIN.

UPDATED THE FORECAST EARLIER TO INCREASE POPS FOR THOSE IN THE
TRACK OF THE BAND OF SHOWERS. OTHERWISE...THE FORECAST LOOKS
GOOD...AND NO FURTHER UPDATES ARE ANTICIPATED THIS MORNING.

&&

.AVIATION...SHOWERS AND ISOLATED THUNDERSTORMS WILL MOVE THROUGH
KSLC TERMINAL AREA IN THE 15Z-19Z WINDOW. PERIODIC CIGS AOB 6000FT
AGL CAN BE EXPECTED...AND A 10 PERCENT CHANCE EXISTS THAT LIGHTNING
WILL IMPACT THE TERMINAL. A BRIEF BREAK IN SHOWERS/STORMS IS
POSSIBLE BEHIND THIS WAVE MIDDAY...BUT ADDITIONAL STORMS SHOULD
REDEVELOP IN THE VICINITY OF THE TERMINAL MID AFTERNOON AND LINGER
THROUGH THE EVENING. SOUTHERLY WINDS HAVE TRANSITIONED TO NORTHWEST
FOR THE DAY.

&&

.FIRE WEATHER...TODAY AND TOMORROW WILL BE WARM AND FAIRLY DRY
ACROSS THE SOUTH...WHILE THE NORTH REMAINS COOL AND MOIST. THE BEST
CHANCE FOR A WETTING RAIN IS ALSO ACROSS THE NORTH. RAIN WILL
OVERSPREAD THROUGH THE MORNING...WITH NUMEROUS SHOWERS AND SCATTERED
THUNDERSTORMS THIS AFTERNOON. IT SHOULD REMAIN ACTIVE ACROSS THE
NORTH TONIGHT AND TOMORROW AS WELL. THE STRONGEST ACTIVITY WILL
BRING A CHANCE FOR CLOUD TO GROUND LIGHTNING...GUSTY/ERRATIC
WINDS...AND SMALL HAIL.

THE PATTERN SHIFTS FRIDAY THROUGH THE WEEKEND AS A RIDGE BUILDS IN.

.SYNOPSIS...AN UPPER LOW MOVING OUT OF THE PACIFIC NORTHWEST WILL
IMPACT MUCH OF UTAH THROUGH THURSDAY. HIGH PRESSURE WILL
STRENGTHEN ACROSS THE REGION LATE IN THE WEEK THROUGH THE UPCOMING
WEEKEND RESULTING IN A WARMING AND DRYING TREND.

&&

.SHORT TERM (THROUGH 06Z SUNDAY)...AN UPPER LOW SPINNING ACROSS
THE INTERIOR PACIFIC NORTHWEST EARLY THIS MORNING WILL GRADUALLY
MEANDER SOUTHEAST ACROSS SOUTHERN ID OVER THE NEXT 24 TO 36 HOURS
BEFORE SHEARING APART AS IT REACHES THE CENTRAL ROCKIES THURSDAY
NIGHT INTO FRIDAY. WHILE THE CENTER OF CIRCULATION WILL REMAIN
JUST NORTH OF THE FORECAST AREA...A SERIES OF PERTURBATIONS
ROTATING AROUND THIS FEATURE WILL BRING SEVERAL WAVES OF SHOWERS
AND THUNDERSTORMS TO NORTHERN AND CENTRAL UT THROUGH THURSDAY.

ONE SUCH WAVE IS CURRENTLY MAKING ITS WAY THROUGH NORTHERN NV
WHERE SHOWERS AND THUNDERSTORMS HAVE PERSISTED OVERNIGHT. HI-RES
MODEL GUIDANCE HOLDS THIS BAND TOGETHER AS IT CROSSES NORTHERN UT
THIS MORNING...WITH ADDITIONAL CONVECTION EXPECTED TO DEVELOP THIS
AFTERNOON FROM A COMBINATION OF DAYTIME HEATING AND A MOIST AND
UNSTABLE BOUNDARY LAYER. FURTHER SOUTH DRIER AIR HAS SPREAD INTO
SOUTHERN UT WHICH SHOULD GREATLY LIMIT CONVECTIVE COVERAGE THIS
AFTERNOON.

AS THE UPPER CIRCULATION CROSSES SOUTHEAST ID TONIGHT INTO EARLY
THURSDAY...THE MODELS HAVE BEEN CONSISTENT IN DEVELOPING
WIDESPREAD PRECIPITATION ACROSS THE NORTHERN HALF OF THE FORECAST
AREA DURING THIS TIMEFRAME. THIS LARGELY RESULTS FROM THE
INFLUENCE OF AN UPPER JET ALONG THE WESTERN PERIPHERY OF THIS LOW
COUPLED WITH A MORE PRONOUNCED VORTICITY LOBE TONIGHT...FOLLOWED
BY A MOIST AND UNSTABLE NORTHWEST FLOW INTO THURSDAY.

BY FRIDAY MID LEVEL RIDGING IS FORECAST TO QUICKLY BUILD ACROSS
THE GREAT BASIN AND REMAIN IN PLACE INTO THE UPCOMING WEEKEND.
LINGERING BOUNDARY LAYER MOISTURE MAY SUPPORT ISOLATED TERRAIN
BASED CONVECTION FRIDAY...OTHERWISE ANTICIPATE A SUBSTANTIAL
WARMING AND DRYING TREND AREAWIDE.

.LONG TERM (AFTER 06Z SUNDAY)...RIDGE AXIS WILL SHIFT SLIGHTLY EAST
SUNDAY IN RESPONSE TO INLAND PROGRESSION OF THE NEXT PACIFIC TROUGH.
A NET INCREASE OF SOUTHWESTERLY FLOW ALOFT COUPLED WITH DEEP MIXING
OF THE AIRMASS WILL PROMOTE BOTH BREEZY SOUTHERLY WINDS AND FURTHER
SURFACE WARMING INTO EARLY NEXT WEEK. MADE MINIMAL CHANGES TO GRIDS
AS THIS PATTERN SHIFT HAS BEEN WELL HANDLED BY PREVIOUS FORECASTS.

TRACK AND EVOLUTION OF AFOREMENTIONED TROUGH HAS PRESENTED MINIMAL
SPREAD IN GLOBAL GUIDANCE SINCE 00Z...ESPECIALLY FOR BEING 5 TO 7
DAYS OUT. AN INITIAL SHORT WAVE IS EXPECTED TO TRACK NORTHEAST
THROUGH NV MONDAY INTO TUESDAY TIGHTENING NEAR H7 BAROCLINICITY
ACROSS FAR NORTHWESTERN UTAH. HIGH BASED CONVECTION POTENTIAL WILL
BE ON THE RISE AS SUCH. A TRAILING SHORT WAVE IS EXPECTED TO THEN
CARVE A BIT FURTHER EAST WITHIN THE MEAN LONGWAVE TROUGH SURGING A
SHALLOW BUT NOTED COLD FRONT THROUGH NORTHERN UTAH LATE
TUESDAY...LIKELY EXPANDING COVERAGE OF ISOLATED TO WIDELY SCATTERED
STORMS ACROSS THE NORTHERN THIRD OF THE AREA INTO WEDNESDAY.

&&

.AVIATION...SIMILAR TO YESTERDAY SHOWERS AND ISOLATED THUNDERSTORMS
WILL MOVE THROUGH KSLC TERMINAL AREA IN THE 15Z-19Z WINDOW. PERIODIC
CIGS AOB 6000FT AGL CAN BE EXPECTED...AND A 10 PERCENT CHANCE EXISTS
THAT LIGHTNING WILL IMPACT THE TERMINAL. A BRIEF BREAK IN
SHOWERS/STORMS IS POSSIBLE BEHIND THIS WAVE MIDDAY...BUT ADDITIONAL
STORMS SHOULD REDEVELOP IN THE VICINITY OF THE TERMINAL MID
AFTERNOON AND LINGER THROUGH THE EVENING.

.FIRE WEATHER...UNSETTLED AND WET CONDITIONS WILL CONTINUE THROUGH
TOMORROW AS A PACIFIC LOW ENCROACHES UPON THEN PASSES THROUGH THE
DISTRICT. PERIODIC SHOWERS AND STORMS ARE EXPECTED TO OCCUR THROUGH
THAT TIME...WITH FOCUS OVER THE NORTHERN HALF OF THE AREA. ELEVATED
WETTING RAIN POTENTIAL WILL CONTINUE.

HIGH PRESSURE WILL BUILD INTO THE DISTRICT BEGINNING FRIDAY AND WILL
STRENGTHEN OVER THE WEEKEND...BEFORE SHIFTING EAST EARLY NEXT WEEK.
SIGNIFICANTLY DRIER AND WARMER CONDITIONS ARE EXPECTED DURING THAT

AS THIS PATTERN SHIFT HAS BEEN WELL HANDLED BY PREVIOUS FORECASTS.

TRACK AND EVOLUTION OF AFOREMENTIONED TROUGH HAS PRESENTED MINIMAL
SPREAD IN GLOBAL GUIDANCE SINCE 00Z...ESPECIALLY FOR BEING 5 TO 7
DAYS OUT. AN INITIAL SHORT WAVE IS EXPECTED TO TRACK NORTHEAST
THROUGH NV MONDAY INTO TUESDAY TIGHTENING NEAR H7 BAROCLINICITY
ACROSS FAR NORTHWESTERN UTAH. HIGH BASED CONVECTION POTENTIAL WILL
BE ON THE RISE AS SUCH. A TRAILING SHORT WAVE IS EXPECTED TO THEN
CARVE A BIT FURTHER EAST WITHIN THE MEAN LONGWAVE TROUGH SURGING A
SHALLOW BUT NOTED COLD FRONT THROUGH NORTHERN UTAH LATE
TUESDAY...LIKELY EXPANDING COVERAGE OF ISOLATED TO WIDELY SCATTERED
STORMS ACROSS THE NORTHERN THIRD OF THE AREA INTO WEDNESDAY.

&&

.AVIATION...SIMILAR TO YESTERDAY SHOWERS AND ISOLATED THUNDERSTORMS
WILL MOVE THROUGH KSLC TERMINAL AREA IN THE 15Z-19Z WINDOW. PERIODIC
CIGS AOB 6000FT AGL CAN BE EXPECTED...AND A 10 PERCENT CHANCE EXISTS
THAT LIGHTNING WILL IMPACT THE TERMINAL. A BRIEF BREAK IN
SHOWERS/STORMS IS POSSIBLE BEHIND THIS WAVE MIDDAY...BUT ADDITIONAL
STORMS SHOULD REDEVELOP IN THE VICINITY OF THE TERMINAL MID
AFTERNOON AND LINGER THROUGH THE EVENING.

&&

.FIRE WEATHER...UNSETTLED AND WET CONDITIONS WILL CONTINUE THROUGH
TOMORROW AS A PACIFIC LOW ENCROACHES UPON THEN PASSES THROUGH THE
DISTRICT. PERIODIC SHOWERS AND STORMS ARE EXPECTED TO OCCUR THROUGH
THAT TIME...WITH FOCUS OVER THE NORTHERN HALF OF THE AREA. ELEVATED
WETTING RAIN POTENTIAL WILL CONTINUE.

HIGH PRESSURE WILL BUILD INTO THE DISTRICT BEGINNING FRIDAY AND WILL
STRENGTHEN OVER THE WEEKEND...BEFORE SHIFTING EAST EARLY NEXT WEEK.
SIGNIFICANTLY DRIER AND WARMER CONDITIONS ARE EXPECTED DURING THAT
PERIOD...WITH INCREASINGLY BREEZY SOUTHERLY WINDS BEGINNING SUNDAY
AS ANOTHER PACIFIC TROUGH TRANSITIONS INTO THE EASTERN GREAT BASIN
FOR THE MIDWEEK PERIOD.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
413 AM MDT WED MAY 27 2015

.SYNOPSIS...AN UPPER LOW MOVING OUT OF THE PACIFIC NORTHWEST WILL
IMPACT MUCH OF UTAH THROUGH THURSDAY. HIGH PRESSURE WILL
STRENGTHEN ACROSS THE REGION LATE IN THE WEEK THROUGH THE UPCOMING
WEEKEND RESULTING IN A WARMING AND DRYING TREND.

&&

.SHORT TERM (THROUGH 06Z SUNDAY)...AN UPPER LOW SPINNING ACROSS
THE INTERIOR PACIFIC NORTHWEST EARLY THIS MORNING WILL GRADUALLY
MEANDER SOUTHEAST ACROSS SOUTHERN ID OVER THE NEXT 24 TO 36 HOURS
BEFORE SHEARING APART AS IT REACHES THE CENTRAL ROCKIES THURSDAY
NIGHT INTO FRIDAY. WHILE THE CENTER OF CIRCULATION WILL REMAIN
JUST NORTH OF THE FORECAST AREA...A SERIES OF PERTURBATIONS
ROTATING AROUND THIS FEATURE WILL BRING SEVERAL WAVES OF SHOWERS
AND THUNDERSTORMS TO NORTHERN AND CENTRAL UT THROUGH THURSDAY.

ONE SUCH WAVE IS CURRENTLY MAKING ITS WAY THROUGH NORTHERN NV
WHERE SHOWERS AND THUNDERSTORMS HAVE PERSISTED OVERNIGHT. HI-RES
MODEL GUIDANCE HOLDS THIS BAND TOGETHER AS IT CROSSES NORTHERN UT
THIS MORNING...WITH ADDITIONAL CONVECTION EXPECTED TO DEVELOP THIS
AFTERNOON FROM A COMBINATION OF DAYTIME HEATING AND A MOIST AND
UNSTABLE BOUNDARY LAYER. FURTHER SOUTH DRIER AIR HAS SPREAD INTO
SOUTHERN UT WHICH SHOULD GREATLY LIMIT CONVECTIVE COVERAGE THIS
AFTERNOON.

AS THE UPPER CIRCULATION CROSSES SOUTHEAST ID TONIGHT INTO EARLY
THURSDAY...THE MODELS HAVE BEEN CONSISTENT IN DEVELOPING
WIDESPREAD PRECIPITATION ACROSS THE NORTHERN HALF OF THE FORECAST
AREA DURING THIS TIMEFRAME. THIS LARGELY RESULTS FROM THE
INFLUENCE OF AN UPPER JET ALONG THE WESTERN PERIPHERY OF THIS LOW
COUPLED WITH A MORE PRONOUNCED VORTICITY LOBE TONIGHT...FOLLOWED
BY A MOIST AND UNSTABLE NORTHWEST FLOW INTO THURSDAY.

BY FRIDAY MID LEVEL RIDGING IS FORECAST TO QUICKLY BUILD ACROSS
THE GREAT BASIN AND REMAIN IN PLACE INTO THE UPCOMING WEEKEND.
LINGERING BOUNDARY LAYER MOISTURE MAY SUPPORT ISOLATED TERRAIN
BASED CONVECTION FRIDAY...OTHERWISE ANTICIPATE A SUBSTANTIAL
WARMING AND DRYING TREND AREAWIDE.

.LONG TERM (AFTER 06Z SUNDAY)...RIDGE AXIS WILL SHIFT SLIGHTLY EAST
SUNDAY IN RESPONSE TO INLAND PROGRESSION OF THE NEXT PACIFIC TROUGH.
A NET INCREASE OF SOUTHWESTERLY FLOW ALOFT COUPLED WITH DEEP MIXING
OF THE AIRMASS WILL PROMOTE BOTH BREEZY SOUTHERLY WINDS AND FURTHER
SURFACE WARMING INTO EARLY NEXT WEEK. MADE MINIMAL CHANGES TO GRIDS
AS THIS PATTERN SHIFT HAS BEEN WELL HANDLED BY PREVIOUS FORECASTS.
