AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
517 AM MST WED FEB 13 2008

.SYNOPSIS...A STRONG COLD FRONT WILL MOVE SOUTH ACROSS UTAH TODAY
THROUGH THIS EVENING. A COLD UNSTABLE AIRMASS WILL REMAIN OVER THE
AREA THURSDAY. HIGH PRESSURE WILL RETURN LATE IN THE WEEK...AND
REMAIN IN PLACE THROUGH THE WEEKEND.

&&

.DISCUSSION...A STRONG UPPER TROF IS DIGGING THROUGH THE PACIFIC
NORTHWEST THIS MORNING WITH A STRENGTHENING COLD FRONT MOVING INTO
SRN ID. STRONG SURFACE PRESSURE FALLS OVER NRN UT AHEAD OF THE
FRONT ARE KICKING UP THE SOUTH WINDS AND THESE SHOULD PERSIST
UNTIL THE FRONT ARRIVES.

MODELS CONTINUE TO DEPICT THE COLD FRONT WILL BE STRONG AS IT
CROSSES THE FORECAST AREA WITH FAIRLY INTENSE PRECIP AND GUSTY
WINDS ACCOMPANYING IT AND CONTINUING FOR SEVERAL HOURS BEHIND IT.
THIS WILL SERIOUSLY IMPACT TRAVEL WITH NEAR BLIZZARD CONDITIONS
AND RAPID SNOW ACCUMULATION ON ROADS SO HAVE OPTED TO GO WITH
WINTER STORM WARNINGS FOR THE I-15 CORRIDOR AND ADJACENT MTS FOR
THIS REASON EVEN IF SNOW AMOUNTS MAY COME UP A LITTLE SHY OF
WARNING CRITERIA. THE LATEST 06Z RUNS ACTUALLY HAVE SOMEWHAT
HIGHER QPF THAN THE 00Z ONES...SO AMOUNTS COULD REACH CRITERIA
AFTER ALL.

THE FRONT MOVES OUT OF THE FORECAST AREA AFTER MIDNIGHT BUT THE
UPPER LOW IS NOW FORECAST TO CLOSE OFF A BIT FARTHER NORTH AND
SHOULD KEEP PRECIP GOING OVER CENTRAL AND SOUTHERN UT INTO THU AS
IT DRIFTS SOUTH ALONG THE WRN UT BORDER INTO SRN NV DURING THE
DAY.

PRECIP SHOULD END THU NIGHT AND THE AIRMASS ALOFT WARMS RAPIDLY
FRI AS A SHORT WAVE RIDGE MOVES INTO THE AREA. VALLEYS COULD BE
SLOW TO RESPOND AS COLD AIR AND FRESH SNOW COVER SHOULD CREATE
STRONG INVERSIONS.

RIDGE CONDITIONS PERSIST THROUGH MID WEEK NEXT WEEK WITH A COUPLE
OF WEAK WAVES POSSIBLY BRINGING SOME CLOUDINESS SAT AND AGAIN
TUE...ALTHO THE EC DOES NOT HAVE THE TUE WAVE AND MAY BE BETTER.

&&

.AVIATION...SOUTH WINDS AT SLC TERMINAL WILL BECOME GUSTY THIS
MORNING AHEAD OF AN APPROACHING COLD FRONT. THIS COLD FRONT IS
EXPECTED TO SHIFT WINDS TO THE NORTHWEST BETWEEN 19Z AND 21Z...WITH
SNOW BEGINNING SOON AFTER THE WIND SHIFT. A PERIOD OF AT LEAST 2
HOURS OF HEAVY SNOWFALL IS EXPECTED...WITH IFR OR LIFR CONDITIONS
LIKELY.
