AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1006 AM MDT THU MAY 8 2008

.SYNOPSIS...DRIER CONDITIONS WILL PREVAIL TODAY AS A STORM SYSTEM
MOVES EAST OF THE STATE THIS AFTERNOON. THE NEXT STORM SYSTEM WILL
IMPACT THE AREA FRIDAY NIGHT AND SATURDAY...FOLLOWED BY HIGH
PRESSURE ALOFT FOR THE LATTER HALF OF THE COMING WEEKEND.

&&

.DISCUSSION...CLOUDS ARE HEADING EAST OF THE AREA THIS MORNING AS
THE STORM SYSTEM THAT MOVED THROUGH THE STATE YESTERDAY EXITS. A
FEW PRECIP ECHOES REMAIN OVER THE FAR SOUTH IN ASSOCIATION WITH
THE COLD FRONT...BUT THESE SHOULD DISSIPATE AS THE BOUNDARY
CONTINUES TO WEAKEN. A WEAK SHORTWAVE BEHIND THE MAIN SYSTEM IS
ALLOWING SOME SHALLOW INSTABILITY TO REMAIN OVER THE NORTH...BUT
THIS IS NOT PRODUCING MUCH MORE THAN SOME TOWERING CUMULUS. WITH
WEAK UPPER RIDGING MOVING IN BY LATER THIS AFTERNOON...THE SUPPORT
FOR THIS WILL DIMINISH. OTHERWISE...SUNSHINE AND A WARMING AIRMASS
WILL ALLOW TEMPERATURES TO WARM TO AROUND SEASONAL NORMALS TODAY.

THE BREAK IN THE ACTION LOOKS TO BE SHORT LIVED AS THE MODELS
REMAIN IN GOOD AGREEMENT ABOUT THE NEXT WAVE...WHICH WILL MOVE
THROUGH THE STATE TOMORROW. RUNS THIS MORNING DO NOT INDICATE
QUITE AS STRONG AS A SYSTEM AS THEY DID YESTERDAY...AND SEEM TO
BE A BIT FARTHER NORTH WITH THE TRACK OF THE WAVE.
THUS...PRECIPITATION LOOKS LIKE IT WILL BE GENERALLY CONFINED TO
NORTHERN AND CENTRAL UTAH. THE WAVE AND ASSOCIATED COLD FRONT ARE
EXPECTED TO NOSE INTO THE STATE FRIDAY AFTERNOON. WHILE THE FRONT
MAKES IT THROUGH THE STATE BY EARLY SATURDAY MORNING...THE UPPER
TROUGH IS EXPECTED TO HANG AROUND UNTIL SATURDAY AFTERNOON. THE
COLD FRONT LOOKS SIMILARLY STRONG TO THE ONE YESTERDAY...AND IS
EXPECTED TO DROP MAXES TO ABOUT 10F UNDER CLIMO WITH THE CLOUD
COVER. HOWEVER...RAPID WARMING AND DRYING IS EXPECTED SUNDAY AS
HIGH PRESSURE DEVELOPS OVER THE FORECAST AREA...ALLOWING MAXES TO
WARM TO VALUES AT OR ABOVE CLIMO ONCE AGAIN.

NO UPDATES EXPECTED TO THE FORECAST THIS MORNING.

&&

.AVIATION...EST WINDS AT SLC TERMINAL THIS MORNING ARE EXPECTED TO
TURN MORE NORTHERLY THROUGHOUT THE DAY. OTHERWISE...VFR CONDITIONS
AND CEILINGS ABOVE 7000FT AGL WILL PREVAIL FOR TODAY.

&&

.FIRE WEATHER...A STABLE AIRMASS WITH GENERALLY LIGHT WINDS WILL
SETTLE INTO THE AREA THIS AFTERNOON. A DRIER WESTERLY FLOW WILL
DEVELOP OVER SOUTHERN UTAH FRIDAY AHEAD OF A COLD FRONT. WINDY
CONDITIONS WILL RESULT WITH RELATIVE HUMIDITY EXPECTED TO DROP TO 10
TO 15 PERCENT. THIS SYSTEM LOOKS TO BE DRIER AND FURTHER NORTH THAN
YESTERDAYS SYSTEM...SO CRITICAL FIRE WEATHER CONDITIONS APPEAR TO BE
MORE LIKELY THAN YESTERDAY. WILL LOOK AT THE MOST RECENT MODEL RUNS
TODAY TO DETERMINE WHETHER THE FIRE WEATHER WATCH FOR ZONES 439 AND
440 SHOULD BE UPGRADED TO A RED FLAG WARNING DURING THIS SHIFT.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...FIRE WEATHER WATCH FROM 2 PM FRIDAY TO 9 PM FRIDAY FOR UTAH
FIRE WEATHER ZONES 439 AND 440.
