AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
334 PM MDT SUN SEP 19 2010

.SYNOPSIS...A DRY AND UNSEASONABLY WARM SOUTHWESTERLY FLOW WILL
REMAIN ACROSS THE GREAT BASIN THIS EVENING INTO TONIGHT. A COLD
FRONT WILL PUSH THROUGH THE REGION MONDAY. SOUTHWEST FLOW WILL
RETURN TUESDAY. ANOTHER TROUGH WILL CROSS THE REGION WEDNESDAY
INTO THURSDAY.

&&

.DISCUSSION...WATER VAPOR IMAGERY CONTINUES TO INDICATE A TROUGH
IS APPROACHING THE PACIFIC NORTHWEST THIS AFTERNOON. CURRENT
MESOWEST OBSERVATIONS SHOW STRONG WINDS ACROSS MUCH OF THE
AREA...BUT GUSTS REMAIN BELOW WIND ADVISORY CRITERIA. STRONG CROSS
WINDS WILL CONTINUE TO OCCUR ACROSS EAST-WEST ROADWAYS INCLUDING
I-80 FROM THE NEVADA/UTAH BORDER THROUGH SALT LAKE CITY INTO THE
EVENING.

AS DECOUPLING OCCURS OVERNIGHT...SMOKE FROM THE TWITCHELL CANYON
FIRE IS EXPECTED TO BEGIN TO SETTLE INTO THE SEVIER AND SANPETE
VALLEYS AND POSSIBLY AS FAR NORTH AS SOUTHERN SALT LAKE COUNTY.
ADDED AREAS OF SMOKE TO THE FORECAST TO HIGHLIGHT THE POTENTIAL
FOR VISIBILITY ISSUES WITH THE SMOKE OVERNIGHT AND INTO THE
MORNING. TRAVELERS IN THESE AREAS...INCLUDING PORTIONS OF
I-15...SHOULD BE PREPARED FOR REDUCED VISIBILITIES WITH LITTLE TO
NO NOTICE.

THE DIFFUSE TROUGH WILL MOVE ACROSS THE AREA MONDAY...BRINGING THE
ASSOCIATED COLD FRONT ACROSS THE STATE MONDAY MORNING INTO MONDAY
EVENING. BUFR SOUNDINGS POINT TO LITTLE TO NO POSSIBILITY OF ANY
PRECIPITATION ACROSS MUCH OF THE CWA WITH THIS SYSTEM. BEST CHANCE
FOR PRECIPITATION WILL BE ACROSS THE SOUTHEASTERN PORTION OF THE
CWA AS MOISTURE IS DRAWN NORTH AND EAST AHEAD OF THE TROUGH. THINK
THE BULK OF THE PRECIPITATION WILL BE TO THE EAST OF THE AREA
THOUGH.

SOUTHWESTERLY FLOW WILL INCREASE ONCE AGAIN TUESDAY IN RESPONSE
TO THE NEXT TROUGH APPROACHING THE WEST COAST. THIS WILL BRING
ANOTHER DAY OF DRY AND WINDY CONDITIONS TO THE STATE TUESDAY.

AS THE TROUGH MOVES CLOSER TO THE EASTERN GREAT BASIN TUESDAY
EVENING INTO TUESDAY NIGHT...MOISTURE IS EXPECTED TO BEGIN TO BE
PULLED NORTHWARD INTO SOUTHERN UTAH. THE 12Z GFS WAS FURTHER EAST
WITH THE MOISTURE SURGE...WHILE THE 12Z EC IS FURTHER WEST.
ADDED/INCREASED POPS IN THESE AREAS...MAINLY FOLLOWING THE GFS
WITH A NUDGE TOWARDS THE EC SOLUTION. MOISTURE WILL QUICKLY BE
SWEPT OUT OF THE STATE AS THE TROUGH PUSHES EAST OF THE AREA
BY LATE WEDNESDAY. HIGH PRESSURE WILL THEN BUILD INTO THE AREA FOR
THE END OF THE WEEK.

THE MAIN WEATHER THREAT FOR TODAY INTO TOMORROW WILL CONTINUE TO
BE SEVERE FIRE WEATHER CONDITIONS. PLEASE REFER TO THE FIRE
WEATHER DISCUSSION FOR MORE DETAILS.

&&

.AVIATION...GUSTY SOUTH WINDS WILL LIKELY CONTINUE AT THE SLC
TERMINAL THROUGH THIS AFTERNOON INTO THIS EVENING. A SHIFT TO THE
NORTHWEST IS NOT EXPECTED...BUT THERE IS A 20 PERCENT CHANCE THAT A
WIND SHIFT MAY OCCUR BETWEEN 00 AND 01Z. IF THIS DOES OCCUR...SPEEDS
WILL STAY UNDER 10KT AND WINDS WILL LIKELY RETURN TO SOUTHERLY BY
03Z. WINDS ARE EXPECTED TO SHIFT TO NORTHWEST WITH A COLD FRONT
AROUND 13Z MONDAY. VFR CONDITIONS WILL CONTINUE THROUGH THE FORECAST
PERIOD. CIGS NEAR 10KFT AGL MAY OCCUR AFTER 12Z.

&&

.FIRE WEATHER...THE APPROACHING PACIFIC TROUGH AND ASSOCIATED
COLD FRONT WILL REACH UTAH MONDAY MORNING...BUT WILL PRIMARILY
IMPACT NORTHERN UTAH. THIS SYSTEM WILL USHER IN COOLER AIR MAINLY
ACROSS THE NORTH. A CHANCE FOR SHOWERS WILL ALSO DEVELOP OVER
SOUTHEAST UTAH AS MOISTURE CREEPS UP FROM THE SOUTH. THE RED FLAG
WARNING FOR MOST OF THE DISTRICT WILL REMAIN IN PLACE THROUGH 900
PM THIS EVENING.

THE RED FLAG WARNING ACROSS SOUTHERN UTAH FOR MONDAY IN THE PRE-
FRONTAL AREA WILL ALSO REMAIN IN EFFECT. THE WEAK SYSTEM WILL BE
GONE RATHER QUICKLY WITH A RETURN TO HIGH PRESSURE AND INCREASING
SOUTHWEST WINDS LATER TUESDAY. WITH THE RAPID RETURN OF STRONG
SOUTHWEST WINDS AND LOW HUMIDITIES...A FIRE WEATHER WATCH HAS BEEN
ISSUED FOR MOST OF WESTERN UTAH.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT... RED FLAG WARNING FROM NOON TO 9 PM MDT MONDAY FOR
      UTZ431-432-435>441.
