AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
930 AM MST TUE FEB 14 2006

.SYNOPSIS...A WEAK COLD FRONT WILL MOVE INTO NORTHERN AREAS TODAY
AND STALL ACROSS CENTRAL UTAH THIS AFTERNOON. A STRONG COLD UPPER
TROUGH WILL MOVE THROUGH THE AREA WEDNESDAY AND PUSH THE COLD FRONT
THROUGH THE STATE.

&&

.DISCUSSION...LEADING EDGE OF BAROCLINIC ZONE OVER N. UT THIS
MORNING. BAND OF RADAR ECHOES NEAR OGDEN LIKELY TO PRODUCE SNOW
SHOWERS. CAMERAS SHOW SNOW FELL FOR AN HOUR OR SO IN LOGAN AND
SNOWING IN HUNTSVILLE AT THIS TIME. ACCUMLATIONS LESS THAN AN INCH.
SOME SNOW SHOWERS POSSIBLE SOUTH INTO SL COUNTY THIS AFTERNOON...BUT
NO ACCUMULATION EXPECTED AND THAT SHOULD BE ABOUT IT FOR THIS
FEATURE. FRONT STALLS AND FLOW BACKS PUSHING THE FRONT AT 700 MB
BACK NORTHWARD TONIGHT. BAND OF PRECIP TONIGHT WILL BE MAINLY IN
AREAS ALREADY IN SNOW ADVISORY.

VERY COLD UPPER TROUGH DROPPING SE INTO PACNW THIS MORNING WITH SNOW
TO SEA LEVEL ALONG WA COAST. 500 MB COLD POCKET MAKES IT INTO N. NV
AND THEN GOES DIRECTLY OVER N. UT WED AFTERNOON. ALL MODELS SIMILAR
AND CONFIDENCE IS HIGH IN THIS EVENT FOR WIDESPREAD SNOW WED THROUGH
ABOUT MID DAY THURSDAY. 12Z ETA IS A TAD SLOWER TO GET GOING ON
PRECIP WED MORNING...BUT HANGS ON LONGER INTO NOON THURSDAY FOR A
LONGER EVENT. LATEST 12Z ETA ALSO HAS MUCH MORE QPF THAN PREVIOUS
RUNS WITH STORM TOTALS OF NEARLY 1 INCH NEAR ALTA AND MORE THAN .5
LIQUID EQUIVALENT IN THE VALLEYS.  QUICK LOOK AT EARLY PANELS OF 12Z
GFS INDICATES IT IS ALSO WETTER THAN PREVIOUS RUNS.

THIS STORM HAS VERY GOOD VERTICAL STRUCTURE WITH WESTWARD TILT WITH
HEIGHT...TRACK OF 700 MB CLOSED CIRCULATION JUST S. OF
YELLOWSTONE...DIRECT HIT WITH 500 MB COLD POCKET...AND JET SUPPORT.
RESULT OVER N. UTAH IS PROLONGED PERIOD OF FAVORABLE LOW LEVEL NW
FLOW AROUND BACK SIDE OF 700 LOW WHILE ALOFT DESTABILIZING AND
DYNAMICALLY LIFTING UPPER FLOW FROM THE SW. IDEAL SET UP FOR AREAS
ALONG URBAN CORRIDOR THAT ARE FAVORED BY POST-FRONTAL NW
FLOW...EASTERN SL COUNTY...SOUTHEAST UTAH COUNTY AND WASATCH
MOUNTAINS SOUTH OF I-80....WED NIGHT NIGHT EVEN HAS SOME LAKE EFFECT
POTENTIAL AS PERIOD OF UNIDIRECTIONAL SHEAR AND VERY UNSTABLE
AIRMASS SEEN IN LATEST SLC BUFR SOUNDINGS...THIS MAY BE WHY ETA QPF
HAS INCREASED SO MUCH FOR SL COUNTY AREA.

OTHER AREA THAT STILL LOOKS GOOD IS I-15 CORRIDOR AND CENTRAL
MOUNTAINS FROM NEPHI TO CDC WED AFTERNOON THROUGH EARLY THU AS VERY
ACTIVE FRONT MOVES SOUTH THROUGH THE AREA.

BIG QUESTION FOR THIS AFTERNOON WILL BE WHETHER TO GO SNOW ADVISORY
OR HEAVY SNOW WARNING FOR ZONES FROM SLC SOUTHWARD.

NO UPDATES TO CURRENT FORECASTS AT THIS TIME.

&&

.AVIATION...COLD FRONT THROUGH SLC 18Z BRING CIGS DOWN TO 5K UNTIL
04-06 UTC...THEN BACK UP TO 7K.
