AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
1000 AM MST SUN MAR 22 2009

.SYNOPSIS...A STRONG PACIFIC STORM SYSTEM NOW MOVING INTO THE GREAT
BASIN WILL BRING BREEZY TO WINDY CONDITIONS THIS
AFTERNOON...ALONG WITH A SLIGHT CHANCE OF SHOWERS TONIGHT ACROSS THE
WHITE MOUNTAINS. TEMPERATURES WILL BE MUCH COOLER MONDAY FOLLOWED BY
A MODERATE WARMING TREND THE MIDDLE OF NEXT WEEK.

&&

.DISCUSSION...THE LARGE UPPER LEVEL TROUGH WEVE BEEN TALKING ABOUT
OVER THE LAST SEVERAL DAYS IS NOW ACROSS CALIFORNIA PER LATEST
SATELLITE AND WATER VAPOR IMAGERY. AHEAD OF THE TROUGH WERE
CURRENTLY SEEING A BAND OF MID AND HIGH LEVEL CLOUDINESS FROM THE
WHITE MOUNTAINS TO NORTHERN BAJA PUSHING SLOWLY EASTWARD WITH PARTLY
CLOUDY SKIES EXPECTED TODAY. THIS TROUGH WILL MOVE INTO THE GREAT
BASIN THIS AFTERNOON THROUGH TONIGHT AND THEN ACROSS COLORADO MONDAY
MORNING. THIS TRACK IS FAVORABLE TO BRING BREEZY TO WINDY CONDITIONS
TO SOUTHEASTERN ARIZONA THIS AFTERNOON AND EVENING BUT LITTLE
MOISTURE THIS FAR SOUTH. CURRENT FORECAST DEPICTING BREEZY TO WINDY
CONDITIONS THIS AFTERNOON LOOKS GOOD WITH WIND SPEEDS REMAINING
BELOW WIND ADVISORY THRESHOLDS DURING THE AFTERNOON HOURS.
HOWEVER...THE STRONGEST WIND CORE IN THE MID LEVELS WILL MOVE
THROUGH THIS EVENING WHICH WILL RESULT IN GUSTY WINDS FOR THE WHITE
MOUNTAINS OF NORTHERN GREENLEE COUNTY AND OTHER MOUNTAINTOP AREAS
ABOVE 7000 FEET. GIVEN LATEST TRENDS AND GUIDANCE WILL OPT TO ISSUE
WIND ADVISORY FOR NORTHERN GREENLEE COUNTY THIS EVENING. ALTHOUGH
MOISTURE WILL BE LIMITED THIS FAR SOUTH...THE WHITE MOUNTAINS OF
NORTHERN GREENLEE COUNTY WILL SEE A SLIGHT CHANCE OF SHOWERS
TONIGHT. MUCH COOLER TEMPERATURES ARE EXPECTED MONDAY WITH CONTINUED
BREEZY CONDITIONS MAINLY ACROSS THE SAN SIMON/UPPER GILA RIVER
VALLEY AREA WHERE FAVORABLE TERRAIN ORIENTATION WILL ENHANCE WEST TO
NORTHWEST WINDS.

&&

.FIRE WEATHER...LOW PRESSURE OVER NORTHERN CALIFORNIA THIS MORNING
WILL MOVE THROUGH THE GREAT BASIN THIS AFTERNOON. THIS WILL RESULT
IN TIGHT PRESSURE GRADIENTS ACROSS SOUTHEAST ARIZONA THIS AFTERNOON
WHILE MOISTURE ASSOCIATED WITH THIS SYSTEM WILL STAY ACROSS NORTHERN
ARIZONA. MINIMUM RELATIVE HUMIDITY VALUES THIS AFTERNOON WILL FALL
BELOW THE 15 PERCENT THRESHOLD OVER MUCH OF FIRE WEATHER ZONE 148
(COCHISE...SANTA CRUZ...EASTERN PIMA AND SOUTHERN PORTIONS OF GRAHAM
AND GREENLEE COUNTIES) BY 1100 MST...BUT WIND SPEEDS ARE NOT
EXPECTED TO MEET RED FLAG CRITERIA UNTIL BETWEEN 1300 AND 1400 MST
THIS AFTERNOON. LATEST MODEL DATA THIS MORNING HAS RELAXED THE WIND
SPEEDS SLIGHTLY...BUT WIDESPREAD BREEZY TO WINDY CONDITIONS LOOK
CERTAIN FOR MUCH OF SOUTHEAST ARIZONA. HOWEVER...MINIMUM RELATIVE
HUMIDITY VALUES WILL REMAIN ABOVE THE 15 PERCENT THRESHOLD IN MUCH
OF SOUTHEAST PINAL COUNTY. WHILE ZONE 147 WILL LIKELY EXPERIENCE RED
FLAG CONDITIONS THIS AFTERNOON...THESE CONDITIONS WILL NOT BE LONG
LIVED OR WIDESPREAD ENOUGH...SO THE FIRE WEATHER WATCH THERE WAS
CANCELLED EARLIER THIS MORNING. RED FLAG CONDITIONS ARE STILL LIKELY
TO ARISE THIS AFTERNOON IN ZONE 148...WHERE A RED FLAG WARNING HAS
BEEN ISSUED FOR 1 PM MST TO 7 PM MST.

ONCE THIS SYSTEM DEPARTS...CONDITIONS WILL REMAIN DRY BUT WINDS WILL
DIMINISH EXCEPT IN GRAHAM COUNTY ALONG THE GILA RIVER AND THROUGH
THE SAN SIMON VALLEY. THIS AREA IS SUSCEPTIBLE TO GUSTY NORTHWEST
WINDS WHEN A SYSTEM MOVES EAST. RELATIVE HUMIDITY VALUES MONDAY
AFTERNOON WILL BE IN THE 10-15% RANGE WHILE THE WIND SPEEDS AT THIS
TIME WILL BE JUST BELOW RED FLAG CRITERIA. FOR NOW SEE NO REASON
TO ISSUE ANY ADDITIONAL PRODUCTS...BUT WILL MONITOR.

&&

.AVIATION...LAYERED CLOUDS ABOVE 18KFT AGL TODAY AS A SYSTEM MOVES
THROUGH THE GREAT BASIN. WIND AT THE TERMINAL SITES...EXPECT THE
WIND TO BECOME SOUTH THIS MORNING AROUND 8-12 KTS THEN INCREASE THIS
AFTERNOON TO 15-25 KTS WITH GUSTS BETWEEN 30-38 KTS. WIND SPEEDS
WILL DIMINISH AFTER SUNSET AND BE LESS THEN 10 KTS AFTER 23/04Z.
AVIATION DISCUSSION NOT UPDATED FOR TAF AMENDMENTS.

&&

.PREV DISCUSSION...WE WILL SEE A BRIEF RESPITE BETWEEN SYSTEMS
DURING THE TUESDAY AND WEDNESDAY TIME PERIOD. HOWEVER...ANOTHER
SYSTEM IS EXPECTED TO BRUSH BY NORTHEAST ARIZONA THURSDAY THROUGH
FRIDAY. I INCREASED POPS SLIGHTLY FOR THE WHITE MOUNTAINS DURING
THIS TIME PERIOD. HOWEVER... THERE IS STILL SOME UNCERTAINTY AS TO
WHAT THIS NEXT SYSTEM WILL DO...SO I DIDNT MAKE ANY SIGNIFICANT
CHANGES.

HIGHS WILL GENERALLY BE 6 TO 8 DEGS ABOVE NORMAL TODAY...THEN 6 TO 8
DEGS BELOW NORMAL FOR MONDAY. HIGHS ON TUESDAY WILL BE SLIGHTLY
BELOW NORMAL...AND NEAR NORMAL FOR WEDNESDAY AND THURSDAY. FOR
FRIDAY HIGHS SHOULD BE AROUND 5 TO 7 DEGS BELOW NORMAL...AND NEAR
NORMAL AGAIN ON SATURDAY. LOWS WILL BE 2 TO 4 DEGS ABOVE NORMAL FOR
MONDAY MORNING...THEN 2 TO 4 DEGS BELOW NORMAL FOR TUESDAY AND
WEDNESDAY. FOR THURSDAY AND FRIDAY LOWS WILL BE 2 TO 4 DEGS ABOVE
NORMAL.
