AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
930 AM MST FRI NOV 18 2005

.SYNOPSIS...A RIDGE OF HIGH PRESSURE ALONG THE WEST COAST WILL
RESULT IN CONTINUED WARM AFTERNOON TEMPERATURES AND DRY CONDITIONS
ACROSS SOUTHEAST ARIZONA. A WEAK UPPER LOW IN THE EASTERN PACIFIC
WILL EVENTUALLY PUSH EAST INTO THE DESERT SOUTHWEST BY THE MIDDLE OF
NEXT WEEK...RESULTING IN AN INCREASE IN CLOUD COVER AND A COOL DOWN
IN AFTERNOON TEMPERATURES THE END OF NEXT WEEK.
&&

.DISCUSSION...THE MAIN CONCERNS IN THE SHORT-TERM WILL BE GUSTY EAST
WINDS TODAY FOLLOWED BY A WIDESPREAD FREEZE TONIGHT IN COCHISE...
PARTS OF GRAHAM COUNTIES...AND POSSIBLY SANTA CRUZ COUNTY AS WELL.
SO FAR...WIND SPEEDS ACROSS SOUTHEAST ARIZONA WERE STILL FAIRLY
LIGHT WITH MOST OF THE GUSTY WINDS ACROSS NORTHERN AND CENTRAL
ARIZONA THIS MORNING. STILL EXPECTING THE WIND TO PICKUP BY NOON
TODAY...BUT OVERALL SHOULD NOT BE STRONG ENOUGH TO WARRANT AN
ADVISORY. LATEST MODEL GUIDANCE SUGGESTED THAT THE WIND WILL DROP
OFF IN SPEED TONIGHT ALLOWING TEMPERATURES TO FALL TO OR SLIGHTLY
BELOW FREEZING AT SEVERAL VALLEY LOCATIONS ACROSS GRAHAM...
COCHISE...AND SANTA CRUZ COUNTIES. A FEW SITES HAVE ALREADY
EXPERIENCED A FREEZE EITHER LAST NIGHT OR WEDNESDAY NIGHT...BUT A
MORE WIDESPREAD FREEZE WILL BE POSSIBLE TONIGHT ACROSS OUR EASTERN
CWA(EAST OF TUCSON). A FREEZE WARNING MIGHT BE ISSUED LATER TODAY
FOR THESE AREAS AFTER THE LATEST MODEL GUIDANCE HAS BEEN THROUGHLY
REVIEWED. OTHERWISE...A HIGH PRESSURE RIDGE ALONG THE WEST COAST
WILL SHIFT INLAND OVER THE WEEKEND PROVIDING THE REGION WITH DRY AND
ABOVE NORMAL HIGH TEMPERATURES. GFS MODEL WAS STILL SHOWING A LOW
PRESSURE SYSTEM UNDERCUTTING THE RIDGE AND POSSIBLY IMPACTING AT
LEAST SOUTHERN ARIZONA BY MID OR LATE NEXT WEEK. CURRENT FORECAST
STILL LOOKED REASONABLE IN THE EXTENDED WITH THE TREND OF SHOWING
MORE CLOUDINESS AND COOLER DAYTIME TEMPERATURES.
&&

.AVIATION...TAF AND TWEBS ADEQUATELY COVER ALL SIGNIFICANT WEATHER
AT KTUS.
&&

.FIRE WEATHER...A SHORTWAVE DISTURBANCE WITH AN AXIS CURRENTLY
RUNNING ALONG THE COLORADO/NEW MEXICO BORDER WILL TRAVEL SOUTHWARD
AS THE DAY PROGRESSES. AS IT DOES SO...WINDS WILL INCREASE DUE TO
THE TIGHTENING PRESSURE GRADIENT OVER SE AZ.  THIS...COUPLED WITH
THE EXTREMELY DRY AIRMASS OVERHEAD...WILL MERIT SOME ATTENTION.
WHILE THERE MAY BE MOMENTS AND LOCATIONS THAT NEAR RED FLAG CRITERIA
IN THE VERY LATE MORNING AND EARLY AFTERNOON...RED FLAG CONDITIONS
ARE NOT EXPECTED TO PERSIST FOR THE THREE CONTINUOUS HOURS REQUIRED
TO VALIDATE ANY WATCH OR WARNING.
&&

.TWC WATCHES/WARNINGS/ADVISORIES...NONE.
