AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
900 PM MST TUE MAR 30 2010

.SYNOPSIS...A STRONG PACIFIC STORM SYSTEM WILL ARRIVE ON THE
CALIFORNIA COAST BY WEDNESDAY EVENING. AS THIS STORM SYSTEM
APPROACHES...EXPECT STRONG SOUTHWEST WINDS AND BLOWING DUST TO
INCREASE ACROSS SOUTHEAST ARIZONA WEDNESDAY AFTERNOON AND WEDNESDAY
NIGHT. VALLEY RAIN AND MOUNTAIN SNOW SHOWERS ARE LIKELY THURSDAY
AFTERNOON THROUGH THURSDAY NIGHT. EXPECT MUCH COOLER TEMPERATURES
WITH THE PASSAGE OF THIS STORM...WITH AFTERNOON HIGH TEMPERATURES
WELL BELOW NORMAL ON THURSDAY AND FRIDAY. FOLLOWING THE STORM...A
RAPID WARMING TREND IS EXPECTED OVER THE WEEKEND.

&&

.DISCUSSION...NEW NAM IS COMING IN WETTER AND A TOUCH SLOWER WITH
THE 00Z RUN. THIS WOULD TEND TO SLIGHTLY MODERATE DEVELOPING WIND
CONDITIONS WEDNESDAY AS WELL AS CREATE MORE PROBLEMS WITH
UNSEASONABLY LOW SNOW LEVELS THURSDAY NIGHT. THE CURRENT FORECAST
HAS GOOD TRENDS...ESPECIALLY WITH 2ND PERIOD WIND HEADLINES AND FIRE
WEATHER CONCERNS...BUT WE WILL BE CAREFULLY ANALYZING OUR SNOW
LEVELS FOR THURSDAY NIGHT INTO FRIDAY MORNING. WE MAY NOT BE GIVING
THIS STORM ENOUGH CREDIT.

&&

.PREV DISCUSSION...LARGE AND COLD PACIFIC TROUGH EVIDENT OF IR
SATELLITE IMAGERY THIS AFTERNOON...WITH AN IMPRESSIVE FIELD OF COLD
AIR CUMULUS. UPPER TROUGH EXPECTED TO CONSOLIDATE INTO A 537 DM
CLOSED LOW JUST WEST OF SAN FRANCISCO BY WEDNESDAY EVENING...WITH
SOUTHWESTERLY FLOW AND PRESSURE GRADIENTS INCREASING ACROSS THE CWA.
SOUTHWEST WINDS OF 20-30 KTS WILL BE COMMON WEDNESDAY AFTERNOON AND
EVENING...WITH GUSTS NEAR 40 KTS AT WIND PRONE LOCATIONS AND IN
COCHISE COUNTY. A WIND ADVISORY WILL BE IN EFFECT FOR THE ENTIRE CWA
FROM 11AM THROUGH 8PM MST WEDNESDAY. PLOWING OF FIELDS HAS BEGUN
ACROSS MUCH OF THE AREA...SO EXPECT WE WILL SEE SOME PROBLEMS WITH
BLOWING DUST BY AFTERNOON. THE TYPICAL DUST PRONE LOCALES SUCH AS
INTERSTATE 10 NORTHWEST OF TUCSON/PINAL COUNTY...AND THE WILLCOX
PLAYA WILL HAVE  TO BE MONITORED CLOSELY TOMORROW. BLOWING DUST
INSERTED INTO GRIDS FOR ALL LOCALES BELOW 6000 FEET. STILL PLENTY
WARM TOMORROW...WITH MOST LOWER DESERTS IN THE LOWER 80S. COUPLED
WITH THE WINDS AND LOW HUMIDITY WE WILL HAVE TO ADDRESS FIRE WEATHER
ISSUES...SEE BELOW.

STRONG WINDS WILL CONTINUE ESPECIALLY FOR THE HIGHER TERRAIN THROUGH
THE NIGHTTIME HOURS WEDNESDAY EVENING AND NIGHT. FEELING IS MANY
VALLEY LOCATIONS WILL BE ABLE TO DECOUPLE AT LEAST SOMEWHAT...BUT
PRESSURE GRADIENTS WILL CONTINUE TO TIGHTEN OVERNIGHT...AND FUTURE
SHIFTS WILL HAVE TO WATCH THIS TIME PERIOD CLOSELY FOR HIGH WIND
CRITERIA DESPITE THE UNFAVORABLE TIME OF DAY. FOR NOW...WE ARE
ISSUING A HIGH WIND WATCH ABOVE 5500 FEET FOR NORTHERN
GREENLEE...GRAHAM...CENTRAL AND EASTERN PIMA...AND SANTA CRUZ
COUNTIES FOR POTENTIAL WIND GUSTS OVER 60 MPH WEDNESDAY EVENING AND
WEDNESDAY NIGHT. IN ADDITION...A HIGH WIND WATCH IS IN EFFECT FOR
COCHISE COUNTY ABOVE 4500 FEET FOR THIS SAME TIME FRAME. THE TYPICAL
WIND PRONE LOCALES FOR STRONG SOUTHWEST FLOW WILL BE SUSCEPTIBLE TO
POTENTIALLY DAMAGING WIND GUSTS...SUCH AS NEAR SIERRA VISTA/FORT
HUACHUCA.

BY MIDDAY THURSDAY...COLD STORM IS EXPECTED TO BE CENTERED NEAR SAN
DIEGO...WITH CONTINUED STRONG WINDS ESPECIALLY SOUTHEAST OF TUCSON
WHERE GRADIENTS WILL BE TIGHTEST. FURTHER WIND HEADLINES WILL VERY
LIKELY BE NEEDED THURSDAY...BUT WILL DEFER TO FUTURE SHIFTS FOR
THESE. FIRST...THIS WILL AVOID SOME CONFUSION WITH PREVIOUS
HEADLINES ALREADY IN EFFECT...AND SECOND THERE ARE SOME
DISCREPANCIES REGARDING HOW STRONG WINDS WILL BE THURSDAY. 12/18Z
NAM PROG A SIGNIFICANT WIND EVENT FOR ESPECIALLY COCHISE COUNTY
THURSDAY...WITH 12Z MET GUIDANCE PROGGING 42 KTS SUSTAINED WINDS AT
KDUG AT 21Z. STRONG WINDS AND BLOWING DUST WILL LIKELY BE A PROBLEM
AHEAD OF THE COLD FRONT FOR THE SOUTHEAST CWA FOR MUCH OF
THURSDAY...ESPECIALLY IF THE TROUGH SLOWS ITS PROGRESSION ANY
FURTHER. INSERTED MORE DUST INTO THE GRIDS FOR AREAS EAST OF TUCSON
THURSDAY AFTERNOON AND EVENING.

WINDS WILL CLEARLY BE THE MAIN CALLING CARD FROM THIS STORM...BUT WE
WILL HAVE SOME PRECIP AS WELL. 18Z NAM PLACES 546 DM LOW OVER
WESTERN PIMA COUNTY 00Z FRIDAY...WITH SHOWERS AND EMBEDDED
THUNDERSTORMS SPREADING ACROSS THE WESTERN CWA BY THURSDAY AFTERNOON.
VALLEY RAIN AND MOUNTAIN SNOW WILL PROGRESS FROM WEST TO EAST
THURSDAY EVENING/NIGHT AS NEAR 547 LOW TRACKS VERY NEAR OR JUST
NORTH OF TUCSON. QUITE COLD ALOFT...SO PRECIP LIKELY TO BE
CONVECTIVE/SHOWERY IN NATURE RESULTING IN VARYING QPF...BUT AS A
GENERAL RULE EXPECT MOUNTAIN SNOW AMOUNTS TO REMAIN BELOW ADVISORY
CRITERIA. SO...NO WINTER WEATHER HEADLINES NECESSARY TODAY. BY 12Z
FRIDAY...TROUGH AXIS EXPECTED TO BE EAST OF US WITH SNOW SHOWERS
WINDING DOWN IN THE WHITE MOUNTAINS.

ABRUPTLY COLDER THURSDAY...WITH TEMPERATURES AT MANY LOWER
ELEVATIONS HOLDING IN THE 50S FOR MUCH OF THE DAY. POTENTIAL FOR
NONDIURNAL TEMP TRENDS ESPECIALLY WITH PRECIP MOVING IN DURING THE
AFTERNOON HOURS. QUITE COLD FRIDAY AND AGAIN SATURDAY
MORNINGS...WITH KTUS DROPPING TO NEAR 40 AND COLDER LOCALES FLIRTING
WITH FREEZING. FINALLY...A RAPID WARMING TREND AWAITS US BEHIND THIS
STORM OVER THE COMING WEEKEND.

&&

INCREASED SOUTHWEST WINDS. SOUTHWEST WINDS AVERAGING 20-30 KTS AT
THE TAF SITES AFTER 18Z WEDNESDAY. AVIATION DISCUSSION NOT UPDATED
FOR TAF AMENDMENTS.

.FIRE WEATHER...WINDS WILL INCREASE SIGNIFICANTLY BY LATE WEDNESDAY
MORNING AS A STRONG PACIFIC STORM SYSTEM MOVES INTO THE REGION.
