AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
941 AM MDT THU OCT 4 2012

.SYNOPSIS...A DRY...STABLE AND COOL NORTHWEST FLOW WILL REMAIN OVER
UTAH THROUGH THE WEEKEND.

&&

.DISCUSSION...A DRY AND STABLE WEST-NORTHWEST FLOW HAS SETTLED
OVER THE CWA THIS MORNING...SOUTH OF A BROAD TROUGH THAT IS
CURRENTLY OVER MUCH OF THE NORTH-CENTRAL PART OF THE CONUS. CLEAR
SKIES EXIST ACROSS THE NORTHERN TWO-THIRDS OF THE FORECAST
AREA...WHILE SOME MID-TO-HIGH LEVEL CLOUDS MOVE ACROSS THE
SOUTHERN THIRD OF UTAH IN THE WESTERLY FLOW. MODELS INDICATE A
CHANCE OF SOME CUMULUS DEVELOPMENT OVER THE FAR SOUTHERN AND
EASTERN PORTIONS OF THE STATE THIS AFTERNOON...BUT THUNDERSTORMS
DO NOT SEEM LIKELY IN OUR FORECAST AREA AT THIS TIME.

WITH STABLE WEATHER CONTINUING THROUGH THE FIRST HALF OF THE
FORECAST PERIOD...THE MAJOR FOCUS WILL BE ON TEMPERATURES...AS
REINFORCING SHOTS OF COLD AIR MOVE INTO THE AREA FROM THE NORTH.
WILL LIKELY PUT FROST IN THE FORECAST FOR TONIGHT ALONG THE
WASATCH FRONT...AND WILL TAKE A CLOSE LOOK AT TEMPERATURE TRENDS
TO SEE IF ANY HARD FREEZE HEADLINES SHOULD BE CONSIDERED FOR THE
NEXT FEW DAYS.

A MINOR UPDATE TO THE FORECAST WAS ISSUED EARLIER THIS
MORNING...TO ADD ADDITIONAL CLOUD COVER TO THE SOUTHERN PORTIONS
OF UTAH THROUGH TODAY. OTHERWISE...THE FORECAST LOOKS GOOD...AND
NO FURTHER UPDATES ARE PLANNED FOR THIS MORNING.

&&

.AVIATION...LIGHT SOUTHERLY WINDS AT THE KSLC TERMINAL WILL SHIFT TO
LIGHT NORTHERLY AROUND 17-18Z THEN RETURN TO LIGHT SOUTHERLY AROUND
03-04Z. VFR CONDITIONS WILL PREVAIL THROUGH THE TAF PERIOD UNDER
CLEAR SKIES.

&&

.FIRE WEATHER...DRY STABLE CONDITIONS WILL PREVAIL ACROSS MUCH OF
THE AREA TODAY...ALTHOUGH BREEZY AFTERNOON WEST TO SOUTHWEST WINDS
WILL DEVELOP ACROSS THE MOUNTAINS AND THE SOUTH PROVIDING GOOD
HORIZONTAL TRANSPORT. ANOTHER WEAK DRY COLD FRONT WILL CROSS THE
DISTRICT TONIGHT WITH COOL STABLE CONDITIONS AGAIN FRIDAY ACROSS THE
NORTH AND WEST. LOCALLY BREEZY NORTHWEST WINDS WILL DEVELOP OVER THE
HIGHER TERRAIN FRIDAY AFTERNOON AND COULD SPREAD INTO PORTIONS OF
THE EASTERN UTAH BASINS. EVEN THOUGH THE AIRMASS WILL BE VERY DRY
SPEEDS IN THE VALLEYS SHOULD REMAIN BELOW CRITICAL VALUES.
