AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
918 PM MDT FRI OCT 19 2007

.SYNOPSIS...A COLD AND MOIST PACIFIC STORM SYSTEM WILL MOVE INTO THE
AREA LATE TONIGHT THROUGH SUNDAY MORNING. HIGH PRESSURE THEN BUILDS
OVER THE REGION ON MONDAY AND REMAIN IN PLACE THROUGH AT LEAST THE
MIDDLE OF NEXT WEEK.

&&

.DISCUSSION...INITIAL COLD FRONT OUT AHEAD OF THE MAIN AND DEEPER
COLD FRONT IS NOW ENTERING NORTHWEST UTAH. THIS FRONT BROUGHT ABOUT
BY COOLING FROM PRECIPITATION AND CLOUD COVER IN SOUTHERN IDAHO
TODAY. A SECOND COLD FRONT CAN BE ANALYZED WITH A WIND SHIFT AND
PRESSURE TENDENCIES IN CENTRAL OREGON. THAT IS A DEEPER FRONT
EXTENDING TO 500 MB PER THE NAM. THE INITIAL FRONT SHOULD SLOWLY
MOVE INTO NORTHERN UTAH...SUPPORTED BY THE PRECIPITATION STREAMING
EAST ALONG THE IDAHO BORDER. LEADING EDGE OF THE 500 MB COLD
POCKET WILL BRING A NORTHERLY WIND SHIFT INTO UTAH WITH DEEP
CONVECTION DEVELOPING LATE MORNING THROUGH EARLY SATURDAY
AFTERNOON. COLD NORTHWEST FLOW THEN FOLLOWS THROUGH SUNDAY
MORNING. GOOD PATTERN FOR A LAKE EFFECT SNOW EVENT EARLY SUNDAY.
MODEL QPF HAS INCREASED WITH THE 00Z RUN AND EXPECTED A WIDESPREAD
INCH OF PRECIPITATION ABOVE 7000 FEET FROM LITTLE COTTONWOOD
CANYON NORTH AND CLOSER TO 2 INCHES LOCALLY IF A PERSISTENT LAKE
EFFECT BAND FORMS. ONE QUARTER TO A HALF AN INCH LIKELY FOR SOUTH
FACING UINTA RANGE AND THE CENTRAL UTAH MOUNTAINS DOWN TO ABOUT
FISH LAKE. COLD AND BLUSTERY FOR SUNDAY STATEWIDE. LOCAL HEAVY
PRECIPITATION ALSO LIKELY FOR THE NORTHERN AND CENTRAL WASATCH
FRONT VALLEYS SATURDAY AND SATURDAY NIGHT.

FORECAST IN GOOD SHAPE AND NO EVENING UPDATE ANTICIPATED.

&&

.AVIATION...NO AVIATION IMPACTS THROUGH AT LEAST 06Z. MVFR WITH
PERIODS OF IFR POSSIBLE WITH POST FRONTAL PRECIP AFTER ABOUT 13Z
FRIDAY. WIND SHIFT IS CURRENTLY EXPECTED NEAR 15Z...BUT MAY ARRIVE A
BIT EARLIER. THUNDERSTORMS WITH ANOTHER WIND SHIFT POSSIBLE 18-20Z.

&&

.FIRE WEATHER...STRONGER WINDS ACROSS SOUTHERN UTAH SATURDAY MAY
BRING A FEW SITES NEAR RED FLAG CONDITIONS...BUT WITH MARGINAL RH
VALUES...DO NOT ANTICIPATE THE NEED FOR A RED FLAG WARNING. COOL
WET SYSTEM TO BRING WETTING RAINS AND SNOW TO MUCH OF CENTRAL AND
NORTHERN UTAH. EXPECTING STRONG HIGH PRESSURE WITH LOW CI VALUES
EARLY NEXT WEEK.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...WINTER STORM WATCH FROM 6 AM SATURDAY TO 6 AM SUNDAY FOR UTZ007.

     WINTER STORM WATCH FROM 9 AM SATURDAY TO 6 AM SUNDAY FOR UTZ008-
