AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1010 AM MDT WED MAY 28 2008

.SYNOPSIS...A MILD SOUTHWEST FLOW ALOFT WILL REMAIN OVER THE AREA
INTO THURSDAY EVENING. A WEAKENING PACIFIC TROUGH MOVE NORTHEAST
ACROSS THE GREAT BASIN LATE THURSDAY. HIGH PRESSURE ALOFT WILL
DEVELOP FOR THE WEEKEND.

&&

.DISCUSSION...THE UPPER TROUGH CENTERED ALONG THE WEST COAST WILL
MAINTAIN A MILD SW FLOW ALOFT ACROSS THE GREAT BASIN INTO THURSDAY.
THE EMBEDDED SHORTWAVE THAT LIFTED NORTH-NORTHEAST THROUGH WRN UTAH
OVERNIGHT HAS SINCE MOVED INTO SRN ID. SUBSIDENCE IN THE WAKE OF
THIS FEATURE WILL PUT A LID ON CONVECTION THROUGH EARLY THIS
AFTERNOON.

MAY SEE SOME CONVECTION RETURN TO THE HIGHER TERRAIN BY AROUND
MID-AFTERNOON DIFFERENTIAL HEATING WORKING WITH MARGINAL AMOUNTS OF
MOISTURE COULD KICK OFF SHOWERS/STORMS ACROSS THE CNTRL AND NRN HIGH
TERRAIN. JET AXIS ACROSS ERN UTAH THIS AFTERNOON COULD SUPPORT A FEW
STRONG STORMS LATER IN THE AFTERNOON/EARLY EVENING.

THE ABOVE MENTIONED UPPER TROUGH WILL DECAY AND LIFT NE THROUGH THE
BASIN LATE THURSDAY. WEAK DYNAMIC LIFT WILL RUN INTO A MARGINALLY
MOIST AND UNSTABLE AIRMASS ACROSS NW UTAH. THE REMAINDER OF THE
FORECAST WILL BE ON THE DRY SIDE...LIMITING ANY CONVECTION TO THE
HIGHER ELEVATIONS.

THE MEAN TROUGH POSITIONS APPEARS TO RETREAT NEAR 130W....ALLOWING
HEIGHTS TO BUILD ACROSS THE BASIN. WARMER TEMPS WITH A GRADUAL
INCREASE IN AREAL COVERAGE OF DIURNAL CONVECTION LOOKS TO BE THE
RULE OVER THE AREA FRIDAY THROUGH THE COMING WEEKEND.

&&

.FIRE WEATHER...A DRIER SOUTHWEST FLOW WILL PREVAIL ACROSS MOST OF
THE FIRE DISTRICT TODAY. THE EXCEPTION WILL BE OVER THE EXTREME
NORTHWEST AND PERHAPS THE UINTAS WHERE SOME RESIDUAL MOISTURE COULD
BE SUFFICIENT ENOUGH TO PRODUCE BUILDUPS AND AT BEST ISOLATED
THUNDERSTORMS. SOUTHWEST WINDS WILL BE STRONGER OVER THE WESTERN
VALLEYS TODAY BUT FUEL MOISTURE REMAINS SUFFICIENT TO PRECLUDE
SEVERE FIRE CONDITIONS. HOWEVER...ANOTHER DAY OF MOSTLY SUNNY SKIES
AND LOW RELATIVE HUMIDITIES WILL SET THE STAGE FOR RED FLAG WARNING
DUE TO LOW RH AND GUSTY WINDS IN THE FIRE WEATHER ZONES 439 AND 440
FOR THURSDAY.

THE TROUGH OVER THE WEST COAST TODAY WILL MOVE OVER THE NORTHERN
PORTIONS OF THE AREA THURSDAY BRINGING A THREAT OF ISOLATED
THUNDERSTORMS OVER THE CENTRAL MOUNTAINS AND SCATTERED SHOWERS
AND/OR THUNDERSTORMS TO NORTHERN ZONES.

&&

.AVIATION...SOUTH WINDS WILL CONTINUE AT THE SLC TERMINAL THROUGH
TODAY. THERE IS A 40 PERCENT CHANCE THE SOUTH WINDS WILL CONTINUE
BETWEEN 01 AND 04Z.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...FIRE WEATHER WATCH FROM NOON THURSDAY TO 10 PM THURSDAY FOR
     FIRE WEATHER ZONES 439 AND 440.

WY...NONE.
