AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
400 PM MST WED DEC 27 2006

.SYNOPSIS...A PACIFIC STORM SYSTEM WILL IMPACT THE INTER-MOUNTAIN
WEST THROUGH THURSDAY. STRONG HIGH PRESSURE ALOFT TRAILING THIS
STORM WILL SETTLE OVER THE GREAT BASIN BY THE WEEKEND.

&&

.DISCUSSION...THE LARGE PACIFIC SYSTEM IMPACTING THE REGION IS
SPLITTING THIS AFTERNOON. THE SOUTHERN STREAM STREAM PIECE IS
PICKING UP BETTER DYNAMICS AT THE EXPENSE OF THE NORTHERN SYSTEM.
THIS MORNINGS NAM RUN SUGGESTED A CLOSING OFF THE SOUTHERN STREAM
WAVE OVER SOUTHEAST NV WHICH APPEARS TO BE HAPPENING. WEAK BANDING
DEVELOPED EARLIER OVER EAST CENTRAL NV. EXPECT BANDING TO REGENERATE
TO THE NORTHWEST OF THE LOW CENTER AND IMPACT MAINLY THE 1-15
CORRIDOR FROM FILMORE TO CEDAR CITY THIS EVENING. EXPANDED THE
ADVISORY TO INCLUDE ZONES 15 AND 16 AS THESE AREAS COULD SEE BANDING
AS WELL AS UPSLOPING BEHIND THE COLD FRONT TONIGHT.

AS THE LOW CENTER MOVES EAST ACROSS NORTHERN AZ MORE BANDING IS
POSSIBLE. CURRENT MODEL TRENDS SUGGEST A BAND DEVELOPING ACROSS THE
SAN RAFAEL SWELL SOUTHWARD INTO NORTHERN AZ. HAVE UPPED SNOW
FORECAST FOR PORTIONS OF SOUTHCENRAL AND SOUTHEAST UTAH...ALTHOUGH
PINPOINTING BAND GENERATION AREA IS TRICKY.

AS THE SYSTEM PULLS AWAY THURSDAY IT IS EXPECT TO BECOME THE 2ND
MAJOR BLIZZARD EVENT FOR THE HIGH PLAINS THIS MONTH. STRONG CAA
BEHIND THE FRONT WILL ALLOW GAP WINDS TO DEVELOP IN SOUTHWEST UTAH.
ISSUED A WIND ADVISORY FOR 17 AND 19 IN WASHINGTON COUNTY. THE
PARAMETERS ARE STRONG ENOUGH TO WARRANT A HIGH WIND WARNING...BUT
THE ORIENTATION OF THE GRADIENT MAY NOT ALLOW FOR FULL FUNNELING.
GUIDANCE BASED ON LOCAL STUDIES IS SPLIT DOWN THE MIDDLE AS FAR AS
ADVISORY VS. WARNING. WIND GUSTS TO 60 MPH AND HIGHER ARE CERTAINLY
POSSIBLE.

THE CAA WANES SLOWLY THROUGH THURSDAY EVENING AS HIGH PRESSURE
BUILDS INTO THE REGION. COLD NORTHERLY FLOW REMAINS IN PLACE THROUGH
THE WEEKEND...AND OROGRAPHICALLY INDUCES SNOW SHOWERS ARE POSSIBLE
THROUGH FRIDAY ACROSS THE SOUTH CENTRAL MOUNTAINS. NO SIGNIFICANT
SYSTEMS EXPECTED THROUGH EARLY NEXT WEEK.

&&

.AVIATION...WINDS SHOULD REMAIN NORTHERLY DUE TO OUTFLOW FROM THE
SHOWERS TO THE WEST OF THE AIRFIELD. WINDS WILL TURN BACK TO THE
SOUTHWEST AS THE COLD FRONT GETS CLOSER TO THE AIRPORT AT AROUND
02-03Z. WIND GUSTS TO NEAR 20KTS WILL ALSO BE POSSIBLE AHEAD OF THE
FRONT. RAIN SHOWERS WILL CONTINUE WITH SNOW BEGINNING TO MIX IN
AFTER 02Z. OCCASIONAL MVFR CEILINGS AND VISIBILITIES ARE POSSIBLE IN
SHOWERS WITH CONDITIONS BECOMING PREDOMINATELY LOW END MVFR IN SNOW
AFTER 02-03Z...WITH A 30 PERCENT CHANCE OF PERIODS OF IFR IN HEAVIER
SNOW.
