AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
940 AM MDT THU JUN 14 2007

.SYNOPSIS...HIGH PRESSURE ALOFT WILL REMAIN ANCHORED ACROSS THE
SOUTHERN GREAT BASIN THROUGH SATURDAY. A WEAK AND GENERALLY DRY
COLD FRONT WILL MOVE THROUGH NORTHERN UTAH ON SUNDAY.

&&

.DISCUSSION...UPPER TROUGH MOVING THROUGH NORTHERN ROCKIES TODAY.
SHALLOW COLD FRONT ASSOCIATED WITH THIS TROUGH EXTENDS FROM MT TO
SNAKE RIVER VALLEY TO NEAR ELKO. 12Z NAM SHOWS A WIND SHIFT TO NW AT
700 MB THIS AFTERNOON OVER N. UT AND KEEPS 700 MB TEMPS AROUND 11.
THIS IS SLIGHTLY COOLER THAN THE PREVIOUS RUNS OF BOTH THE GFS AND
NAM WHICH HAD 13 AND WINDS MORE WESTERLY.  OTHER HINT OF CHANGE IN
LATEST 12Z NAM IS SLIGHTLY LESS WIND IN SW UT FRIDAY WHICH WILL NEED
TO BE CONSIDERED IN DECISION ON WHETHER TO UPGRADE CURRENT FIRE WX
WATCH TO A RED FLAG WARNING...WILL NEED TO WAIT ON 12Z GFS.

STILL LOOKING WARM FRIDAY AND SATURDAY...BUT NAM WOULD INDICATE
UPPER 90S RATHER THAN TRIPLE DIGIT AT SLC ON SATURDAY. AGAIN WILL BE
LOOKING AT 12Z GFS AND ASSOCIATED MOS GUIDANCE BEFORE WORKING ON
TEMP FORECAST.

NO CHANGES TO CURRENT FORECASTS AT THIS TIME

&&

.FIRE WEATHER...A VERY WARM AND DRY AIRMASS OVER THE FIRE DISTRICT
WILL KEEP AFTERNOON RELATIVE HUMIDITIES BELOW CRITICAL LEVELS FOR
THE NEXT FEW DAYS. WINDS ARE EXPECTED TO INCREASE FRIDAY AND
SATURDAY AHEAD OF AN APPROACHING COLD FRONT AND A FIRE WEATHER WATCH
HAS BEEN ISSUED FOR THE SOUTHWEST AND SOUTH CENTRAL VALLEYS BELOW
8000 FT FOR FRIDAY AFTERNOON THROUGH SUNDAY. WINDS LOOK TO BE
MARGINAL ON FRIDAY SO WILL CONSIDER CANCELLING THE FRIDAY PORTION OF
THE WATCH. WINDS MAY BE STRONG ENOUGH SATURDAY AFTERNOON TO PRODUCE
RED FLAG CONDITIONS IN PORTIONS OF WEST CENTRAL AND NORTHWESTERN
UTAH. HOWEVER...THESE MAY NOT BE LONG ENOUGH IN DURATION TO MEET RED
FLAG CRITERIA. WILL CONSIDER ADDING THESE ZONES TO THE FIRE WEATHER
WATCH WITH THE AFTERNOON PACKAGE.

EXPECTED.
