AREA FORECAST DISCUSSION

.SYNOPSIS...A COLD UPPER LOW WILL CROSS THE NORTHERN AND CENTRAL
ROCKIES TODAY. HIGH PRESSURE WILL RETURN FOR THE LATTER PART OF THE
WEEK. ANOTHER PACIFIC STORM SYSTEM WILL MOVE INTO THE WESTERN STATES
OVER THE WEEKEND.

&&

.DISCUSSION...WELL ADVERTISED UPPER LOW CENTER IS OVER CENTRAL
NEVADA THIS MORNING. 12Z KLKN SOUNDING HAD -24 AT 500 MB. STRONGEST
BAROCLINICITY OUT AHEAD OF THE COLD POOL IS NOW OVER THE NORTHERN
UTAH MOUNTAINS. MOST VIGOROUS VERTICAL MOTION WILL BE BETWEEN 18Z
AND 00Z THIS AFTERNOON ACROSS THE WASATCH FRONT AND INTO THE WESTERN
UINTAS. BEST UVM IS IN THE 800-600 MB LAYER...WHERE TEMPS WILL
REMAIN...OR DROP TO...THE MID AND UPPER 20S. SHOULD HAVE NO PROBLEM
GENERATING PERIODS OF HEAVY SNOW THROUGH THE AFTERNOON IN THESE
MOUNTAIN RANGES. WINTER STORM WARNING WILL REMAIN IN EFFECT INTO THE
EVENING. IT MAY BE CANCELED A FEW HOURS PRIOR TO THE CURRENT
EXPIRATION TIME OF 9PM...AS THERE WILL LIKELY BE A SHARP BACK EDGE
TO THE PRECIP. STRONG WARMING ALOFT AND NVA WILL SWEEP IN BEHIND THE
TROUGH...AND THE LATEST GFS SHOW THIS HAPPENING BY 00Z.
HOWEVER...REAL DATA SUGGESTS THAT THE SYSTEM IS A BIT SLOWER THAN
THE GFS INDICATES. NONETHELESS...THE GFS GETS THE WIN FOR THIS
SYSTEM IN BOTH TIMING AND INTENSITY.

POST-TROUGH WINDS WILL BE QUITE STRONG ACROSS EASTERN UTAH THIS
AFTERNOON. THE OVERNIGHT ZONE PACKAGE ADDRESSES THIS NICELY...SO THE
ONLY UPDATE WILL BE IF A WIND ADVISORY IS ISSUED LATER THIS MORNING.
PRICE IS GUSTING TO NEAR 30 AT THIS TIME...BUT WITH A SHOWER BAND IN
THE AREA. WILL HOLD OFF FOR NOW...BUT AM PREPARED TO ISSUE AN NPW IN
THE NEXT FEW HOURS IF NECESSARY.

DIMINISHING WINDS AND GOOD GROUND MOISTURE SHOULD ALLOW FOR AT LEAST
LOW CLOUDS IF NOT PERIODS OF FOG TONIGHT IN SOME AREAS. WITH LOWS
FORECAST IN THE MID AND UPPER 20S IN THE CACHE AND WASATCH MOUNTAIN
VALLEYS...COULD SEE SOME PICTURESQUE RIMING ON TREES AND POWERLINES
TOMORROW MORNING. MUCH DRIER CONDITIONS WILL ALLOW A BIGGER
TEMPERATURE PLUNGE IN THE CENTRAL VALLEYS DOWN TO ABOUT CEDAR CITY.

THE FLOW SLOWLY BACKS TO WESTERLY THROUGH THURSDAY. A WEAK SHORTWAVE
WILL SKIRT THROUGH THE REGION DURING MORNING...BUT ITS EMBEDDED IN
AN AMPLIFYING RIDGE. DO NOT EXPECT ANY SENSIBLE WEATHER.

THE NEXT SYSTEM OF INTEREST IS A DEEP PACIFIC SYSTEM WHICH DROPS
INTO SOUTHWESTERN UTAH BY SUNDAY...THEN CUTS OFF OVER THE CENTRAL
ROCKIES

&&

.AVIATION...LOW-END MVFR CONDITIONS WILL BE THE RULE TODAY AT SLC.
HOWEVER...PERIODS OF IFR CEILINGS ARE POSSIBLE IN HEAVIER
SHOWERS...ESPECIALLY IN AN OCCASIONAL LAKE-EFFECT BAND.

&&

.FIRE WEATHER...WITH THE FRONT PASSING THROUGH THE REMAINDER OF
SOUTHERN UTAH TODAY...DO NOT ANTICIPATE ANY FIRE WEATHER ISSUES.
EMERGENCY MANAGERS INVOLVED IN ANY EXISTING FIRES IN EASTERN UTAH
SHOULD BE AWARE OF GUSTY WINDS SHIFTING TO THE NORTHWEST TODAY.
