AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
930 AM MST WED FEB 21 2007

.SYNOPSIS...A MILD SOUTHWEST FLOW WILL GIVE WAY TO A COLD PACIFIC
TROUGH THURSDAY NIGHT AND FRIDAY.

&&

.DISCUSSION...QUICK LOOK AT 12Z NAM AND GFS INDICATES LITTLE CHANGE
FROM PREVIOUS MODEL RUNS. A COLD PACIFIC TROUGH MOVES THROUGH THE
AREA THURSDAY NIGHT AND FRIDAY AS AN OPEN WAVE. COLD FRONT ENTERS
EXTREME WESTERN UTAH AFTER MIDNIGHT AND PASSES THROUGH SLC BETWEEN
12Z AND 15Z WITH RAIN CHANGING TO SNOW ON VALLEY FLOORS BEFORE 15Z.
THE TIMING OF THIS CHANGEOVER TO SNOW MIGHT SPARE THE MORNING
COMMUTE FROM SLC SOUTHWARD...ALTHOUGH OGDEN AREA COULD BE INTO SNOW
ABOUT AN HOUR OR SO EARLIER. THIS FROPA IS STILL TWO DAYS AWAY AND
EXACT TIMING OF FROPA MAY CHANGE BUT LATELY TREND HAS BEEN TO SLOW
DOWN THE SYSTEM JUST A TAD. MOUNTAINS LIKELY TO SEE SNOW DEVELOP IN
ADVANCE OF THE FRONT...BUT CURRENT THINKING IS SIGNIFICANT
ACCUMULATION WILL HOLD OFF UNTIL AFTER SUNRISE FRIDAY.

WIND IS THE OTHER MESSAGE WITH THIS STORM. 700 MB WINDS IN THE GFS
REACH 60 KNOTS 06Z FRIDAY WITH FAVORABLE SURFACE PRESSURE GRADIENT.
RIDGETOP GUSTS COULD EASILY BE 80 KNOTS OR MORE OVERNIGHT. WESTERN
VALLEY BOUNDARY LAYER MAY DECOUPLE ENOUGH TO KEEP FROM REACHING WIND
WARNING CRITERIA OVERNIGHT. WILL PONDER THE SITUATION TODAY IN
DECIDING WHETHER TO ISSUE HIGH WIND WATCH OR NOT DEPENDING ON
WHETHER WARNING LEVEL WINDS ARE EXPECTED IN THE VALLEYS...NO
QUESTION ADVISORY LEVEL WINDS WILL BE REACHED...BUT NOCTURNAL TIMING
MAKES WARNING LEVEL A BIT TOUGHER TO REACH IN THE VALLEYS.

NO CHANGES TO CURRENT FORECAST AT THIS TIME.

&&

.AVIATION...NO LAKE BREEZE IS EXPECTED TODAY DUE TO LOWER PRESSURE
IN IDAHO. SOUTHERLY WINDS ARE EXPECTED TO GRADUALLY INCREASE IN
INTENSITY THROUGH TOMORROW AHEAD OF THE NEXT DISTURBANCE. SOUTH
WINDS WILL OCCASIONALLY BE GUSTY THIS AFTERNOON.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
