AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1028 AM MST WED DEC 3 2008
.SYNOPSIS...A COLD NORTHWEST FLOW ALOFT WILL REMAIN OVER UTAH
THROUGH TODAY. THE NEXT WEAK STORM SYSTEM WILL MOVE THROUGH NORTHERN
UTAH AND SOUTHWEST WYOMING LATE WEDNESDAY NIGHT AND THURSDAY. WARM
AND DRY HIGH PRESSURE WILL SETTLE OVER THE AREA FOR FRIDAY AND
SATURDAY.
&&
.DISCUSSION...A COOL NORTHWEST FLOW PERSISTS OVER THE AREA TODAY
WITH ENOUGH MOISTURE OVER THE NORTH TO KEEP CLOUDS BANKED ALONG THE
MTS AND UPSTREAM OUT INTO THE NWRN VALLEYS. SUNNY SKIES PREVAIL OVER
THE REST OF THE AREA AND HAVE UPDATED THE FORECASTS TO ADJUST THE
SKY COVER SOMEWHAT.
12Z MODELS HAVE CONTINUED THE TREND OF THE LAST COUPLE OF RUNS FOR
THE THU SHORT WAVE...SHOWING IT SPLITTING FARTHER SOUTH AND KEEPING
A MORE ORGANIZED BAND OF MOISTURE AND CORRESPONDING GREATER THREAT
OF PRECIP OVER ABOUT THE NORTHERN HALF OF THE CWA INSTEAD OF JUST
THE FAR NORTH. SO LEVEL OF CONFIDENCE HAS INCREASED ON THE CHANCE OF
PRECIP FOR NRN ZONES LATE TONIGHT AND TOMORROW AND WILL BE
SIGNIFICANTLY INCREASING POPS IN THE GRIDS FOR THAT TIME FRAME.
SYSTEM MOVES OUT TOMORROW AFTERNOON WITH MAYBE A FEW LINGERING
SHOWERS INTO THE EVENING. RIDGING STILL EXPECTED FOR FRI AND SAT.
NO ADDITIONAL UPDATES PLANNED.
&&

THE NORTHWEST BY ABOUT 19Z. CONDITIONS WILL BE VFR THROUGHOUT THE
DAY...THOUGH CEILINGS AROUND 6000 FT SHOULD STICK AROUND UNTIL
BETWEEN 18Z AND 20Z BEFORE SCATTERING OUT.
