AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
925 AM MDT TUE JUN 19 2007

.SYNOPSIS...FLOW ALOFT BECOMES SOUTHWESTERLY TODAY THROUGH WEDNESDAY
WITH WARMING TEMPERATURES. A DRY COOL FRONT WILL MOVE THROUGH THE
AREA THURSDAY BEFORE TEMPERATURES WARM RAPIDLY BY THE WEEKEND.

&&

.DISCUSSION...THE RIDGE AXIS IS DIRECTLY OVER UTAH THIS
MORNING...RESULTING IN CLEAR SKIES ACROSS THE AREA. WITH SOUTHWEST
FLOW IN PLACE...SIGNIFICANT WARMING ALOFT IS EXPECTED TODAY. MANY
AREAS...PARTICULARLY OVER THE NORTHERN HALF OF THE STATE...WILL
SEE MAX TEMPS 5-10F WARMER THAN THEY WERE YESTERDAY. THE WARMING
TREND CONTINUES TOMORROW AS THE RIDGE AXIS MOVES EAST OF THE
AREA...BUT SHOULD BE CURBED SOMEWHAT ON THURSDAY AS A WEAK COOL
FRONT MOVES ACROSS THE STATE. WINDS ARE EXPECTED TO PICK UP
WEDNESDAY AHEAD OF THE FRONT...AND THIS SHOULD ACT TO PRODUCE
AREAS OF CRITICAL FIRE WEATHER CONDITIONS. A FIRE WEATHER WATCH
HAS BEEN ISSUED FOR WESTERN UTAH. SEE THE FIRE WEATHER DISCUSSION
FOR MORE DETAILS.

THE WARMING TREND IS EXPECTED TO RETURN FOR FRIDAY AND SATURDAY
WITH THE GFS PREDICTING 700 MB TEMPS AROUND +18C FOR MOST OF THE
STATE. IF THIS ENDS UP HAPPENING...IT COULD PRODUCE SOME OF THE
WARMEST TEMPERATURES SO FAR THIS YEAR...WITH MAXES AROUND 100 IN
PORTIONS OF THE WASATCH FRONT AND SOME AREAS OF SOUTHERN UTAH OVER
5 DEGREES ABOVE THAT. MODELS CONTINUE TO BRING A DRY COLD FRONT
ACROSS AT LEAST THE NORTHERN PART OF THE STATE SUNDAY AND MONDAY.
THERE SHOULD BE ENOUGH COOLING WITH IT TO GET MAX TEMPERATURES OUT
OF NEAR RECORD TERRITORY...BUT THEY SHOULD STILL REMAIN WELL ABOVE
CLIMO.

NO UPDATES EXPECTED TO THE FORECAST THIS MORNING.

&&

.AVIATION...NO SIGNIFICANT DEVIATIONS FROM THE TAF ARE EXPECTED
TODAY AT THE SLC TERMINAL.

&&

.FIRE WEATHER...VERY LOW HUMIDITY WITH AFTERNOON BREEZES. UPPER
RIDGE BUILDING NORTH WILL BRING SIGNIFICANT WARMING TO NORTHERN
AREAS AND EVEN LOWER HUMIDITY THAN YESTERDAY. IN GENERAL WINDS WILL
BE LIGHT EXCEPT FOR DIURNAL AFTERNOON WIND GUSTS 25 TO 30 MPH IN FAR
NORTHEAST UTAH AND ACROSS SOUTHERN UTAH. EXCEPT LIGHTER WINDS FOR
EAST CENTRAL UTAH TODAY. SOUTHERLY WIND FLOW WILL INCREASE ACROSS
WESTERN UTAH ON WEDNESDAY AHEAD OF A WEAK COLD FRONT APPROACHING
FROM THE NORTH. PLAN IS TO UPGRADE WATCH TO WARNING FOR AFTERNOON
PACKAGE. WEAK COLD FRONTAL PASSAGE IN THE NORTH WILL BRING LIGHTER
WINDS ON THURSDAY...BUT REMAINING BREEZY FOR SOUTHERN UTAH AND
LOCALLY ACROSS EAST CENTRAL AND SOUTHEAST UTAH. DECREASE IN WINDS ON
FRIDAY AS THE UPPER RIDGE LIFTS ACROSS THE 4-CORNERS REGION BUT
STILL VERY LOW HUMIDITY ACROSS THE DISTRICT. SOUTHERLY FLOW
INCREASES ENOUGH TO BRING MORE FIRE WEATHER CONCERNS ON SATURDAY FOR
WESTERN UTAH...AND AFTERNOON GUSTS FOR EASTERN UTAH.
