AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
935 AM MST MON DEC 8 2008

.SYNOPSIS...A COLD AND SOMEWHAT MOIST STORM SYSTEM WILL SWEEP SOUTH
ACROSS UTAH TODAY INTO TONIGHT. HIGH PRESSURE WILL RETURN FOR
MIDWEEK FOLLOWED BY A WEAKER SYSTEM THURSDAY.

&&

.DISCUSSION...UPPER TROUGH CONTINUES TO DIVE INTO THE GREAT BASIN
THIS MORNING WITH ASSOCIATED SURFACE COLD FRONT ACROSS CENTRAL UTAH.
A BAND OF PRECIPITATION DEVELOPED ACROSS NORTHERN UTAH WHICH
RESULTED IN SOME LIGHT SNOW ACCUMULATIONS DOWN TO THE VALLEY FLOORS
THIS MORNING. THIS BAND WILL IMPACT THE SALT LAKE AND UTAH VALLEYS
FOR THE LATTER PART OF THE MORNING HOURS. HOWEVER...THE BAND IS
RATHER NARROW...WITH PRECIPITATION ALREADY TAPERING OFF NORTH OF
OGDEN.

VORT MAX EVIDENT OVER FAR SOUTHWEST IDAHO THIS MORNING WILL DIVE
INTO UTAH THIS AFTERNOON AND REINFORCE THE COLD FRONT OVER THE
AREA. EXPECT ANOTHER ROUND OF PRECIPITATION AS THIS FEATURE MOVES
THROUGH...WITH PRECIPITATION ALSO SPREADING INTO CENTRAL AND
SOUTHERN UTAH. IN ADDITION...500MB COLD POOL WITH NEAR -30C AIR WILL
KEEP SOME INSTABILITY SHOWERS GOING THROUGH MOST OF THE NIGHT. WHILE
NORTHERLY FLOW DEVELOPING LATE IN THE DAY WILL NOT BE FAVORABLE FOR
OROGRAPHIC ENHANCEMENT ALONG THE WASATCH...SOUTHERN MOUNTAINS COULD
DO WELL IN THIS FLOW PATTERN. GOING ADVISORIES LOOK FINE FOR
NOW...BUT MAY HAVE TO EVALUATE THE NEED FOR AN ADVISORY LATER TODAY
FOR THE I-15 CORRIDOR OF CENTRAL UTAH.

NORTHERLY FLOW ALOFT WILL INCREASE OVER THE AREA TONIGHT AS THE JET
DIVES DOWN THE BACK SIDE OF THE TROUGH. WITH GOOD SURFACE GRADIENT
ACROSS SOUTHERN UTAH AT THE SAME TIME...CONDITIONS SEEM FAVORABLE
FOR A GAP WIND EVENT FOR WASHINGTON COUNTY CANYONS. AS A
RESULT...MAY HAVE TO ISSUE A WIND HIGHLIGHT WITH THE AFTERNOON
PACKAGE.

HIGH PRESSURE QUICKLY DEVELOPS OVER THE AREA TOMORROW. AFTER A WEAK
BRUSH-BY SYSTEM ON THURSDAY...BROAD COLD TROUGH STILL LOOKS TO
IMPACT THE AREA THIS WEEKEND.

WILL UPDATE MAINLY TO INCREASE SKY COVER FOR TODAY...OTHERWISE
FORECAST LOOKS GOOD.

&&

.AVIATION...INITIAL PRECIP BAND IS OVERHEAD AT THIS TIME BRINGING
MVFR CONDITIONS TO THE SLC TERMINAL. THE TAIL END OF THIS BAND IS
EXPECTED TO PASS RAPIDLY IMPROVING CONDITIONS TO A PERIOD OF VFR
FROM 18Z THROUGH 21Z. THE NEXT AND MORE POTENT WAVE OF PRECIP IS
EXPECTED TO BE ON DOORSTEP AFTER THAT TIME BRINGING PERIODS OF IFR
SNOW IN SNOW BANDS BETWEEN 21Z AND 02Z BEFORE CONDITIONS AGAIN
IMPROVE. WINDS ARE EXPECTED TO REMAIN NORTHERLY THROUGH THIS
EVENINGS PUSH.
