AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
426 PM MDT WED MAY 5 2010

.SYNOPSIS...A COLD FRONT WILL MOVE THROUGH THE AREA THIS EVENING
AND TONIGHT. DRIER AND MORE STABLE CONDITIONS WILL SET UP FOR
THURSDAY AND FRIDAY.

&&

.DISCUSSION...THE COLD FRONT HAS ENTERED NORTHWEST UTAH THIS
AFTERNOON. GUSTY NORTHWEST WINDS HAVE BEGUN ACROSS THE WEST
DESERTS AND MUCH OF THE WASATCH FRONT...WITH THE BOUNDARY BETWEEN
NORTHWESTERLY AND SOUTHERLY WINDS AT ABOUT POINT OF THE MOUNTAIN
AS OF 22Z. WINDS SHOULD INCREASE EVEN MORE THROUGH THE LATE
AFTERNOON AND EVENING HOURS AS THE PRESSURE GRADIENT CONTINUES TO
STRENGTHEN ACROSS THE STATE. WINDS IN THE SOUTHERN PORTION OF THE
STATE MAY INCREASE A BIT THROUGH THE EVENING AS WELL...THOUGH
THOSE WINDS HAVE BEEN GENERALLY WEAKER THAN PREVIOUSLY EXPECTED.
SHOWERS HAVE DEVELOPED WITH THE COLD FRONT...BUT VERY LITTLE IF
ANY PRECIPITATION IS REACHING THE GROUND. THE BEST MOISTURE AND
INSTABILITY WITH THIS SYSTEM WILL REMAIN NORTH OF THE CWA...WITH
THE COLD FRONT BEING THE ONLY REAL IMPACT TO UTAH AND SOUTHWEST
WYOMING WITH THE STORM.

HAVE EXPANDED THE WIND ADVISORY TO THE SOUTHERN WASATCH FRONT...AS
NORTHWEST WINDS GENERALLY BLOW QUITE WELL IN THAT AREA. IN
ADDITION...MOS GUIDANCE AND GRIDDED MODEL DATA CONTINUE TO
INDICATE THAT MANY OF THE VALLEYS IN NORTHERN UTAH WILL DROP TO
FREEZING TEMPERATURES OR BELOW TONIGHT...SO HAVE ISSUED FREEZE
WARNINGS IN THOSE AREAS. THIS IS NO MAJOR SURPRISE AS THE INCOMING
AIRMASS IS QUITE COOL FOR THIS TIME OF YEAR...WITH 700 MB
TEMPERATURES FORECAST TO DROP TO -13 DEGREES CELSIUS IN FAR
NORTHERN UTAH.

AFTER THE COLD FRONT MOVES THROUGH THE ENTIRE STATE BY THURSDAY
MORNING...DRIER AND MORE STABLE ZONAL FLOW WILL SET UP ACROSS THE
GREAT BASIN FOR THURSDAY AND FRIDAY...WITH SLOW WARMING BEGINNING
FRIDAY...AND GENERALLY WARMER TEMPERATURES FOR THE WEEKEND. THE
GFS AND ECMWF ARE CURRENTLY IN GOOD AGREEMENT ABOUT DIGGING A
SHORTWAVE TROUGH INTO CALIFORNIA ON SUNDAY...WITH INCREASING
SOUTHWESTERLY FLOW SETTING UP ACROSS UTAH. DETAILS BEGIN TO
DIVERGE IN THE TWO MODELS ON SUNDAY NIGHT...BUT BOTH INDICATE A
GENERALLY TROUGHY PATTERN ACROSS THE WESTERN CONUS ON MONDAY AND
TUESDAY...SO HAVE INCREASED POPS AND DECREASED TEMPERATURES A BIT
IN THIS TIME FRAME TO INDICATE THE BETTER MODEL AGREEMENT.

&&

.AVIATION...NORTHWESTERLY WINDS WILL PREVAIL AT THE SLC TERMINAL
THROUGH TONIGHT. THERE IS A 20 PERCENT CHANCE THAT WINDS COULD GUST
OVER 35 MPH BETWEEN 00Z AND 03Z THIS EVENING. ALSO CIGS ARE EXPECTED
TO LOWER TO BELOW 7000 FT...WITH THE HIGHEST CHANCE BETWEEN 05Z AND
09Z.

&&

.FIRE WEATHER...A COLD FRONT HAS ENTERED NORTHWEST UTAH...AND WILL
CONTINUE TO MOVE TO THE SOUTHEAST ACROSS THE FIRE DISTRICT THROUGH
THE EVENING. IN THE NORTHERN PART OF THE DISTRICT...WINDS WILL BE
STRONG AND GUSTY BEHIND THE FRONT. IN THE SOUTHERN PORTION OF THE
DISTRICT...WINDS WILL BE STRONG AND GUSTY AHEAD OF THE FRONT AND
WITH THE FRONTAL PASSAGE. WITH DRY CONDITIONS AND THESE STRONG WINDS
ACROSS THE SOUTHERN AND WESTERN PART OF THE FIRE DISTRICT...CRITICAL
FIRE WEATHER CONDITIONS ARE EXPECTED. HOWEVER...NO RED FLAG WARNING
WILL BE ISSUED AS FUELS REMAIN NON CRITICAL.

&&
