AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
340 AM MDT MON SEP 28 2009

.SYNOPSIS...STRONG HIGH PRESSURE WILL KEEP AN UNSEASONABLY WARM
AIRMASS OVER THE GREAT BASIN TODAY. A COLD PACIFIC STORM WILL MOVE
INTO THE GREAT BASIN LATE TUESDAY THROUGH WEDNESDAY...WITH MUCH
COOLER AIR LINGERING THROUGH THE REMAINDER OF THE WEEK.

&&

.DISCUSSION...HIGH PRESSURE WILL SHIFT EAST TODAY AS THE STRONG
PACIFIC TROUGH MOVES ONSHORE. THIS WILL ALLOW FOR INCREASING
SOUTHWEST FLOW TO DEVELOP UNDER A DRY AND UNSEASONABLY WARM
AIRMASS. WITH FULL MIXING...OBSERVED 700 MB TEMPS AROUND +14C
WILL RESULT IN MAXES OVER 15F ABOVE NORMAL...HOT ENOUGH TO
APPROACH RECORD VALUES IN SOME AREAS...INCLUDING THE WASATCH
FRONT.

FLOW ALOFT WILL CONTINUE TO INCREASE TOMORROW AS THE TROUGH AND
ITS ASSOCIATED COLD FRONT APPROACH THE REGION. MODELS ALL
INDICATE 700 MB FLOW OF 30-40 KTS BY TUESDAY AFTERNOON WITH A
STRONG PRESSURE GRADIENT. FIRE WEATHER WATCH HAS ALREADY BEEN
ISSUED...AND IT IS LIKELY THAT ADDITIONAL WIND HEADLINES WILL BE
NEEDED.

WITH 00Z RUNS...THERE REMAINS SOME DISAGREEMENT BETWEEN THE NAM
AND THE GLOBAL MODELS WITH RESPECT TO THE TIMING OF THE COLD
FRONT. GFS/EC INDICATE THE FRONT WILL ENTER THE STATE TOMORROW
EVENING...CROSSING NORTHERN UTAH AROUND MIDNIGHT OR SHORTLY
THEREAFTER...AND MOVING THROUGH THE WHOLE STATE BY WEDNESDAY
AFTERNOON. TIMING IN THE NAM SOLUTION REMAINS ABOUT SIX HOURS
SLOWER. WITH BETTER AGREEMENT AND RUN-TO-RUN CONSISTENCY...HAVE
LEANED TOWARD THE GLOBAL MODELS...BUT IF THE SLOWER SOLUTION IS
CORRECT...WEDNESDAY MORNING MINS WOULD BE QUITE A BIT WARMER THAN
THE GOING FORECAST. BECAUSE THE MINS ON WEDNESDAY DEPEND GREATLY
ON THE FRONTAL TIMING...CONFIDENCE IS LOWER THAN USUAL.

REGARDLESS OF TIMING...ALL MODELS REMAIN IN GOOD AGREEMENT THAT
THE FRONT WILL BRING A DRASTICALLY COOLER AIRMASS TO THE ENTIRE
STATE. BEHIND IT...TEMPERATURES ARE EXPECTED TO DROP 20-30F FROM
TUESDAY AFTERNOON HIGHS...RESULTING IN MAXES UP TO 20F BELOW
CLIMO. WITH VERY GOOD FRONTOGENETIC FORCING...THE BOUNDARY SHOULD
BRING A PERIOD OF HEAVY PRECIPITATION...STRONGEST OVER NORTHERN
AND CENTRAL UTAH. AS THE TROUGH MOVES ACROSS WEDNESDAY AFTERNOON
THROUGH THURSDAY MORNING...THE COLD POOL IS EXPECTED TO MOVE
ACROSS NORTHERN UTAH...RESULTING IN ENOUGH INSTABILITY TO KEEP
SHOWERS GOING. THERE IS SOME DIFFERENCE IN THE MODEL PREDICTED
700 MB TEMPS. 00Z ECMWF INDICATES -6C...WHILE THEY GET AS LOW AS
-8C IN THE GFS. THE GFS SOLUTION WOULD BE COLD ENOUGH TO BRING
SNOW TO BENCH LOCATIONS OF NORTHERN UTAH...WHILE IF THE EC
SOLUTION PANS OUT IT WOULD LIKELY REMAIN IN THE MOUNTAIN VALLEYS
AND ABOVE. EITHER WAY...BEST SNOW ACCUMULATIONS ARE EXPECTED TO
BE ABOVE 7000 FT.

AS THE TROUGH EXITS ON THURSDAY...A DRIER AND MORE STABLE AIRMASS
IS EXPECTED TO MOVE IN BEHIND IT. SOME SHOWERS MAY LINGER INTO
THURSDAY AFTERNOON AND EVENING...BUT THEY SHOULD BE LIGHT. EC/GFS
SHOW WEAK RIDGING FOR FRIDAY AND SATURDAY BEFORE ANOTHER PACIFIC
NORTHWEST TROUGH DROPS INTO THE GREAT BASIN SATURDAY NIGHT AND
SUNDAY MORNING. THOUGH THEY STILL DISAGREE WITH THE
DETAILS...EITHER SOLUTION WOULD BRING MORE WET WEATHER FOR THE
END OF THE WEEKEND AND EARLY NEXT WEEK...SO HAVE GONE WITH ABOVE
CLIMO POPS FOR THE END OF THE FORECAST PERIOD.

&&

.AVIATION...SOUTHEAST WINDS SHOULD REMAIN AT KSLC THROUGH AROUND 16Z
THEN TURN SOUTHWEST AND INCREASE. THERE WILL ONLY BE A 30 PERCENT
CHANCE THAT ANY NORTHWEST LAKE BREEZE DEVELOPS AND IF IT DOES IT
WILL PROBABLY BE DELAYED PAST 20Z.

&&

.FIRE WEATHER...RIDGE AXIS WILL MOVE EAST OF THE FIRE DISTRICT THIS
MORNING OPENING UTAH UP TO AN INCREASED SOUTHWEST FLOW. THIS FLOW IS
AHEAD OF A STRONG WINTER-LIKE STORM SYSTEM THAT WILL PUSH INTO THE
PACIFIC NORTHWEST AND THEN ON INTO UTAH ON WEDNESDAY. HUMIDITY WILL
BE THE LOWEST TODAY STEADILY INCREASING OVER THE NEXT FEW DAYS.
BORDERLINE CRITICAL WINDS TODAY WILL GIVE WAY TO VERY STRONG WINDS
TOMORROW. HUMIDITY MAY REMAIN LOW ENOUGH TUESDAY FOR CRITICAL FIRE
BEHAVIOR AND THE FIRE WEATHER WATCH ISSUED EARLIER WILL BE
CONTINUED. EXPECT POOR MOISTURE RECOVERY AT NIGHT INTO TUESDAY WITH
A CHANGE TO A MUCH WETTER AND COOLER REGIME FOR WEDNESDAY AND
THURSDAY. A SHARP COLD FRONT IS FORECAST TO MOVE SOUTHEAST INTO
CENTRAL UTAH BY WEDNESDAY MORNING...THEN ACROSS THE REMAINDER OF THE
STATE WEDNESDAY AFTERNOON. BREEZY NORTHWEST WINDS WILL FOLLOW THE
FRONT AND THEN TAPER OFF RATHER RAPIDLY. SNOW ABOVE 6000 FEET ACROSS
NORTHERN UTAH WILL ACCOMPANY A 30 TO 35 DEGREE TEMPERATURE DROP.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...FIRE WEATHER WATCH FROM NOON TUESDAY TO 9 PM TUESDAY FOR UTAH FIRE
WEATHER ZONES 420-423-433>435-438-439-445>449.
