.SYNOPSIS...AN UNSEASONABLY COOL TROUGH WILL MOVE ACROSS THE GREAT
BASIN TODAY AND REMAIN THROUGH THURSDAY. THE TROUGH WILL MOVE OUT
AND A WARMING TREND WILL BEGIN FRIDAY AND LAST THROUGH THE
WEEKEND.

&&

.DISCUSSION...SHOWERS AND SOME ISOLATED THUNDERSTORMS CONTINUE TO
DEVELOP THIS AFTERNOON AND SLOWLY PUSH SOUTHEASTWARD. THE COLD
FRONT CURRENTLY STRETCHES ACROSS CENTRAL UT AT THIS TIME AND WILL
CONTINUE TO MOVE THROUGH UTAH...ACCELERATING A BIT THIS EVENING.
STRONG WINDS ARE OCCURRING THROUGH MUCH OF THE CWA. RECEIVED
REPORTS OF WINDS NEARING 56 MPH ACROSS WEST CENTRAL AND PORTIONS
OF SOUTHWEST UTAH. UPGRADED THESE AREAS TO A HIGH WIND WARNING
THROUGH THIS EVENING. CAUTION IS ADVISED ALONG I-15 IN CENTRAL AND
SOUTHERN UTAH AS AREAS OF REDUCED VISIBILITIES IN BLOWING DUST ARE
POSSIBLE THIS AFTERNOON AND EVENING.

SEVERAL AREAS WILL HAVE TO BE MONITORED FOR WIND HEADLINES THIS
EVENING. OBSERVATIONS IN THE RAFT RIVER MOUNTAIN RANGE HAVE BEEN
OVER 50 MPH ALL AFTERNOON. IT IS POSSIBLE THESE WINDS MAY REACH
PORTIONS OF THE LOWER ELEVATIONS OF THE GREAT SALT LAKE
DESERT...ALTHOUGH NOT CONFIDENT IN HIGH WIND CRITERIA BEING
REACHED. HELD OFF ON UPGRADING FOR NOW. ALSO NEED TO WATCH CASTLE
COUNTRY AND THE WESTERN UINTA BASIN FOR A POSSIBLE WIND ADVISORY
AS WINDS ARE NEARING THE BOTTOM END OF THE CRITERIA AT THIS TIME.

PRECIPITATION WILL GRADUALLY DIMINISH IN MANY LOCATIONS TONIGHT.
SNOW MAY MIX IN THE WITH RAIN SHOWERS ACROSS THE CACHE VALLEY LATE
TONIGHT INTO EARLY TOMORROW MORNING...AND A FEW FLAKES CANNOT BE
RULED OUT IN THE HIGHEST BENCH LOCATIONS OF THE NORTHERN AND EVEN
THE CENTRAL WASATCH FRONT.

A VORT LOBE ROTATING AROUND THE STRONG UPPER LEVEL LOW LOCATED
ACROSS THE NORTHERN INTERMOUNTAIN REGION IS EXPECTED TO MOVE
ACROSS NORTHERN AND CENTRAL UTAH WEDNESDAY MORNING INTO WEDNESDAY
AFTERNOON. INCREASED POPS AND QPF TO ACCOUNT FOR THIS. 18Z NAM
BRINGS THIS FEATURE IN FASTER THAN PREVIOUS RUNS. IF THIS IS
ACCURATE...POPS AND QPF MAY BE TOO HIGH TOMORROW AFTERNOON.

THE LARGE UPPER LEVEL TROUGH IS EXPECTED TO BEGIN TO MOVE AWAY
FROM THE AREA THURSDAY...BRINGING SOMEWHAT ZONAL FLOW INTO THE
EASTERN GREAT BASIN FOR THE WEEKEND. A STRONG WARMING TREND IS
EXPECTED THROUGH THE WEEKEND...WITH TEMPERATURES REACHING ABOVE
NORMAL LEVELS BY SATURDAY. THIS ABOVE NORMAL TEMPERATURE PATTERN
IS EXPECTED TO CONTINUE THROUGH AT LEAST MIDWEEK NEXT WEEK.

&&

.AVIATION...CEILINGS BELOW 7000FT AGL AT SLC TERMINAL SHOULD
PERSIST THROUGH 02Z...WITH A 30 PERCENT CHANCE THAT THEY WILL STAY
THROUGH 06Z. WINDS ARE EXPECTED TO STAY FROM THE NORTH THROUGH THE
ENTIRE EVENING...BUT COULD BECOME LIGHT AND VARIABLE OR
SOUTHEASTERLY DRAINAGE WINDS BRIEFLY BETWEEN 06Z AND 12Z. WINDS
COULD ALSO BECOME GUSTY AND ERRATIC DUE TO SHOWER ACTIVITY IN THE
AREA. BRIEF PERIODS OF MVFR CEILINGS OR VISIBILITIES ARE POSSIBLE IN
THE HEAVIEST SHOWERS.

&&

.FIRE WEATHER...VERY DRY CONDITIONS AND WIND GUSTS OF 40 TO 50 MPH
ARE OCCURRING EAST AND SOUTH OF A SURFACE COLD FRONT NOW MOVING
ACROSS CENTRAL UTAH. SEVERE FIRE WEATHER CONDITIONS WILL CONTINUE
FOR EASTERN AND SOUTHERN UTAH ALONG WITH A WIND SHIFT TO WEST OR
NORTHWEST THIS EVENING.

BAND OF PRECIPITATION IN NORTHERN UTAH WILL SAG SOUTHWARD INTO
CENTRAL AND NORTHEAST UTAH THIS EVENING AND THEN DISSIPATE LATER
TONIGHT. ISOLATED THUNDERSTORMS IN THIS BAND AND A CHANCE FOR WETTING
RAIN IN NORTH CENTRAL AND NORTHEAST UTAH.

POOR HUMIDITY RECOVERY IS EXPECTED IN THE SOUTH TONIGHT. DESPITE
COOLER TEMPERATURES IT WILL REMAIN VERY DRY IN THE SOUTH WITH
GUSTY POST FRONTAL NORTHERLY WINDS WEDNESDAY MORNING SO THE
WARNING HAS BEEN EXTENDED. IT REMAINS DRY BUT WINDS GRADUALLY
DECREASE IN THE AFTERNOON.

NUMEROUS SHOWERS AND WIDELY SCATTERED THUNDERSTORMS WILL AFFECT
NORTHERN UTAH DURING WEDNESDAY MORNING AS THE COLD UPPER TROUGH
CROSSES NORTHERN UTAH...WITH A CHANCE FOR WETTING PRECIPITATION.
