AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
915 PM MDT WED SEP 13 2006

.SYNOPSIS...FLAT RIDGE OVER THE AREA INTO EARLY THURSDAY WILL BE
REPLACED BY A COLD TROUGH FRIDAY INTO SATURDAY. A RIDGE WILL
GRADUALLY BUILD INTO THE REGION SUNDAY INTO MONDAY.

&&

.DISCUSSION...DEFORMATION ZONE HAS DEVELOPED OVER WEST CENTRAL UTAH
BETWEEN THE INCOMING TROUGH AND WEAK CIRCULATION OVER CENTRAL
ARIZONA. DUE TO LACK OF DEEP MOISTURE IN THIS REGION THE THREAT OF A
FEW HIGH BASE SHOWERS AND POSSIBLE ISOLATED THUNDERSTORMS SHOULD
DIMINISH BY MIDNIGHT AS THE THETA E RIDGE WEAKENS IN THIS LOCATION.
FARTHER SOUTHEAST DEEPER MOISTURE IS MOVING INTO SOUTH CENTRAL UTAH.
THE GFS SHOWS THAT THE THETA-E RIDGE STRENGTHENS IN THIS REGION
OVERNIGHT. HAVE INCREASED POPS OVER THE SOUTHERN PORTIONS OF THE CWA
AFTER MIDNIGHT. ALSO SATELLITE SHOWING A FEW CIRCULATIONS IN THE
WATER VAPOR OFF THE SOUTH CENTRAL CALIFORNIA COAST WHICH THE GFS
CONSOLIDATES INTO A COUPLE OF SHARP VORTICES ALONG THE CA/NV BORDER
BY 12Z WHICH LOOKS SUSPICIOUS AND THEN ARE CARRIED NORTHEAST INTO
UTAH THURSDAY AFTERNOON. WHILE THESE INDIVIDUAL VORTICES MAY
DEVELOP THERE IS A BETTER CHANCE THAT AN AREA OF DEFORMATION WILL
DEVELOP OVER SOUTHERN UTAH BETWEEN THE MAIN CIRCULATION AND THE
EXITING ONE THAT IS CURRENTLY OVER ARIZONA. THIS SHOULD BRING A
CHANCE OF SHOWERS THERE THURSDAY MORNING.

GFS SEEMS TO BE IN MUCH BETTER AGREEMENT WITH THE SATELLITE IN THE
PACIFIC NORTHWEST THAN THE NAM. STRONG RIDGING OCCURRING BETWEEN 140
AND 150 WEST IS ALLOWING THE TROUGH TO DIG OFF THE PACIFIC NORTHWEST
COAST. THE 00Z NAM PLACES THIS TROUGH AXIS OVER CENTRAL WASHINGTON
BY 06Z. THE GFS IS A LITTLE FARTHER WEST AND PREFERRED. CURRENT
PACKAGE IS BASED ON A MIX OF THE TWO MODELS BUT THE TREND OF THE GFS
MAY BE THE WAY TO GO. MIDNIGHT SHIFT WILL NEED TO ADDRESS THIS.

&&

.AVIATION...NO WEATHER CONCERNS TONIGHT. HOWEVER SOUTH WINDS WILL
SET IN SHORTLY AFTER 9 PM LST AND GRADUALLY INCREASE TONIGHT THROUGH
THURSDAY AFTERNOON. HIGH BASE RAIN SHOWERS MAY INDUCE WIND GUSTS
OVER 30 MPH LATE FRIDAY AFTERNOON.

&&

.FIRE WEATHER...WINDS AND LOW HUMIDITIES THE PROBLEM FOR THURSDAY. A
STRONG COLD FRONT WILL BEGIN TO WORK EAST ACROSS NEVADA THURSDAY...
LEADING TO A MARKED INCREASE IN SOUTH WINDS FOR THE WRN VALLEYS.
HUMIDITIES ARE ALREADY LOW AND AT BEST WILL REMAIN THAT WAY
THURSDAY. CURRENT FIRE WEATHER WATCH LOOKS GOOD FOR NOW.

THE FRONT IS SCHEDULED TO PUSH SE ACROSS UTAH LATE THURSDAY
NIGHT/FRIDAY. STRONG WINDS STILL AN ISSUE AHEAD OF AND NEAR THE
FRONT. HUMIDITIES WILL COME UP ALONG AND BEHIND THE FRONT DUE TO
COOLER TEMPS/PRECIP ACROSS NRN/CNTRL UTAH. SRN UTAH MAY STILL SEE
HAZARDOUS FIRE WEATHER CONDITIONS AHEAD OF THE FRONT ON FRIDAY.
MUCH COLDER TEMPS STATEWIDE FOR THE WEEKEND.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...FIRE WEATHER WATCH FOR THURSDAY MORNING THROUGH EVENING FOR
     FIRE WEATHER ZONES 420-423-434-435-437-439 IN WESTERN UTAH.
WY...NONE.
