AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
352 PM MST WED NOV 24 2010

.SYNOPSIS..A VERY COLD ARCTIC AIRMASS WILL REMAIN IN PLACE ACROSS
THE REGION THROUGH THE REMAINDER OF THE WEEK. SOUTHWEST FLOW WILL
DEVELOP SATURDAY AHEAD OF THE NEXT STORM SYSTEM...WHICH IS
EXPECTED TO IMPACT THE REGION SUNDAY.

&&

.DISCUSSION...UPPER LOW SPINNING ACROSS THE HIGH PLAINS OF EASTERN
MT CONTINUES TO SLOWLY ROTATE EAST THIS AFTERNOON...PULLING MAIN
TROUGH ENCOMPASSING MUCH OF THE WESTERN CONUS EASTWARD AS WELL. VERY
COLD AIRMASS ASSOCIATED WITH THIS TROUGH HAS OVERSPREAD THE FORECAST
AREA...AND AS SKIES CLEAR EXPECT TEMPERATURES TO QUICKLY FALL THIS
EVENING ACROSS MOST AREAS GIVEN FRESH SNOWCOVER. EXCEPTION IS THE
NORTHERN WASATCH FRONT WHERE SHALLOW INSTABILITY IS ALLOWING SNOW
SHOWERS TO SPREAD EAST ACROSS AREAS FROM OGDEN SOUTH TO FARMINGTON.
ANTICIPATE THESE TO CONTINUE INTO THE EVENING HOURS...HOWEVER
WARMING TEMPERATURES ALOFT SHOULD ALLOW FOR A WEAKENING TREND WITH
THIS ACTIVITY...AND ANY ACCUMULATION SHOULD REMAIN MINOR AT BEST.

MID LEVEL RIDGING FORECAST TO BUILD ACROSS THE REGION THROUGH THE
REMAINDER OF THE WEEK...AND RESULTANT WARMING ALOFT WILL
EFFECTIVELY TRAP ARCTIC AIRMASS ACROSS MOST VALLEY LOCATIONS.
MODELS CONTINUE TO ADVERTISE A SHORTWAVE TROUGH MOVING THROUGH
THE REGION LATE SATURDAY INTO SUNDAY...BRINGING A GOOD CHANCE FOR
SNOWFALL TO MOST OF NORTHERN UTAH...BUT ALSO HOPEFULLY PROVIDE
ENOUGH MIXING TO DISLODGE AIRMASS FROM THE VALLEYS.

&&

.AVIATION...SNOW SHOWERS WILL CONTINUE ACROSS NORTHERN UTAH THIS
AFTERNOON...WITH A 20 PERCENT CHANCE OF MVFR CONDITIONS AT THE SLC
TERMINAL BETWEEN 22Z AND 01Z. DESPITE SCATTERED SKIES DIRECTLY

AIRPORT AND ALONG THE HIGHER TERRAIN THROUGH 03Z.
