AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
130 PM MST SAT JUN 21 2008

.SYNOPSIS...STRONG HIGH PRESSURE WILL BRING HOT DAYTIME TEMPERATURES
TO SOUTHEAST ARIZONA...WITH NEAR RECORD TEMPERATURES TODAY. ISOLATED
AFTERNOON AND EVENING THUNDERSTORMS CAN BE EXPECT...MAINLY IN THE
MOUNTAINS...THIS EVENING. OTHERWISE...GENERALLY DRY CONDITIONS CAN
BE ANTICIPATE UNTIL SOME MOISTURE CREEPS BACK IN FROM THE SOUTH
TOWARD NEXT FRIDAY.

&&

.DISCUSSION...VERY HOT TEMPERATURES AND A LITTLE BIT OF MOISTURE
HAS BEEN ENOUGH TO TRIGGER SHOWERS AND THUNDERSTORMS IN THE
MOUNTAINS ACROSS SOUTHEAST ARIZONA EARLY THIS AFTERNOON. THE MAIN
CONCERN WILL BE HOW MUCH AREAL COVERAGE WE CAN EXPECT THE REST OF
THIS AFTERNOON AND EVENING. THE SHOWERS AND STORMS MAY BECOME
ORGANIZED ENOUGH TO TRACK INTO THE VALLEYS LATER ON. WILL NEED TO
WATCH THIS ACTIVITY CLOSELY AS HIGH WINDS WILL BE THE MAIN THREAT.
OTHERWISE...MODELS INDICATED THAT THE HIGH PRESSURE RIDGE WILL
WEAKEN A BIT AS PROJECTED HEIGHTS LOWER FOR TOMORROW AND MONDAY.
THIS SHOULD TRANSLATE TO A DROP OR TWO IN HIGH TEMPERATURES...BUT
STILL WELL ABOVE NORMAL THE NEXT SEVERAL DAYS. GFS MODEL CONTINUED
TO SHOW THE HIGH PRESSURE RIDGE ALOFT SHIFTING SOUTHWARD THROUGH AT
LEAST THE FIRST PART OF NEXT WEEK. THIS SHOULD PUSH THE MOISTURE
CURRENTLY IN PLACE SOUTHWARD THE NEXT A DAY OR TWO WITH THE
THUNDERSTORM THREAT REMAINING OVER MEXICO AND NEAR THE INTERNATIONAL
BORDER BY MONDAY. GFS HAD THE HIGH BECOMING CENTERED OVER SOUTHWEST
NEW MEXICO AND BUILDING NORTHWARD AFTER ABOUT THURSDAY OF NEXT WEEK.
THIS COULD LEAD TO MOISTURE CREEPING BACK INTO THE REGION FOR THE
RETURN OF THUNDERSTORM CHANCES.

&&
.FIRE WEATHER...STRONG HIGH PRESSURE ALOFT WILL CONTINUE THE
REMAINDER OF THIS WEEKEND INTO NEXT WEEK. HOT DAYTIME TEMPERATURES
WITH MINIMUM RELATIVE HUMIDITIES MAINLY IN THE SINGLE DIGITS FOR
MOST AREAS. NO SIGNIFICANT WINDS ARE EXPECTED THE NEXT SEVERAL DAYS
BUT LOCALIZED BREEZES ARE EXPECTED TO DEVELOP EACH AFTERNOON WITH
OCCASIONAL GUSTS TO AROUND 25 MPH. THERE WILL BE ENOUGH MOISTURE FOR
ISOLATED THUNDERSTORM ACTIVITY FROM TUCSON EAST INTO THIS EVENING
AND ONCE AGAIN SUNDAY. WINDS NEAR THESE THUNDERSTORMS WILL BE VERY
GUSTY AND ERRATIC.

&&

.AVIATION...MOSTLY CLEAR SKIES THE REST OF THE AFTERNOON AND EVENING
WEST OF A LINE FROM GLOBE-TUCSON-SASABE. MEANWHILE TO THE EAST OF
THIS LINE...PARTLY CLOUDY SKIES ARE EXPECTED WITH BASES 12-14K FT
AGL. ISOLATED THUNDERSTORMS WILL CONTINUE INTO THE EARLY EVENING
ESPECIALLY NEAR AND OVER THE HIGHER TERRAIN. THE COVERAGE WILL BE
SPORADIC ENOUGH TO PRECLUDE INCLUDING WITH THE TERMINAL FORECAST FOR
KDUG AT THIS TIME. ISOLATED THUNDERSTORMS ARE EXPECTED ONCE AGAIN
SUNDAY MAINLY EAST OF KTUS. WINDS ARE EXPECTED TO BE MAINLY WEST TO
NORTHWEST 5-15 KTS THE REST OF THIS AFTERNOON WITH GUSTS TO 25KTS
BEFORE BECOMING EAST TO SOUTHEAST 5-10 KTS OVERNIGHT. GUSTY AND
VARIABLE WINDS TO 35 KTS POSSIBLE IN AND NEAR THUNDERSTORMS.
AVIATION DISCUSSION NOT UPDATED FOR TAF AMENDMENTS.
