A SLIGHT COOLING TREND IS ALSO EXPECTED IN AFTERNOON TEMPERATURES TO NEAR SEASONAL NORMALS. A WEAK TROUGH IS FORECAST TO PUSH THE MOISTURE FURTHER EAST ALONG THE ARIZONA AND NEW MEXICO BORDER BY TUESDAY. && .DISCUSSION...KEMX WSR-88D DETECTED SCATTERED MOSTLY LESS THAN 35 DBZ ECHOES JUST S OF THE INTERNATIONAL BORDER ADJACENT SANTA CRUZ AND COCHISE COUNTIES AT 1625Z. ISOLATED CELLS WERE DEVELOPING NEAR BISBEE AND W OF NOGALES. THE REST OF SE AZ WAS VOID OF PRECIP ECHOES AT THIS TIME. IR AND VISIBLE SATELLITE IMAGERY INDICATED EXTENSIVE CLOUD MASS OVER CENTRAL-NERN SONORA WITH SCATTERED-BROKEN MAINLY MID-LEVEL CLOUDS EXTENDING AS FAR NORTH AS A SELLS-ORO VALLEY- HANNAGAN MEADOW ARC. WATER VAPOR IMAGERY INDICATED VORT MAX/CYCLONIC CIRCULATION FEATURE MOVING NWWD OVER WRN CHIHUAHUA. A FEW LIGHTNING STRIKES HAVE BEEN DETECTED DURING THE PAST HOUR OVER NE SONORA/NW CHIHUAHUA. 01/12Z KTUS SOUNDING DEPICTED INCREASED MOISTURE THROUGHOUT MUCH OF THE COLUMN VERSUS 24 HOURS AGO...WITH PRECIP WATER VALUE NEAR 1.25 INCHES. FAIRLY UNSTABLE ENVIRONMENT AS WELL WITH LIFTED INDEX VALUE NEAR MINUS 7 AND UNMODIFIED SURFACE-BASED CAPE OF 1985 J/KG.

THUS THE GFS SOLUTION WAS ACCEPTED AND USED AS THE BASIS FOR CHANGES MADE AS OF THIS WRITING TO THE INHERITED POP AND WEATHER GRIDDED DATA FIELDS FOR THIS AFTERNOON AND EVENING. IN ESSENCE OPTED TO INCREASE POPS ABOUT 5 PERCENT OR SO FROM THE TUCSON VICINITY EWD. HAVE ALSO OPTED TO INTRODUCE LOW-GRADE POPS ACROSS ALL BUT FAR WRN PIMA COUNTY FOR LATE TONIGHT INTO FRI MORNING GIVEN THE PROSPECT OF INCREASED MOISTURE AND APPROACHING VORT MAX AS PER THE GFS SOLUTION.

THIS MAY RESULT IN DECREASED MAINLY MID- LEVEL MOISTURE TOWARD THE END OF THE UPCOMING WEEK. HOWEVER IN THE MEANTIME APPEARS THAT MOISTURE WILL BE SUFFICIENT FOR A CHANCE OF AFTERNOON AND EVENING THUNDERSTORMS...MAINLY FOR AREAS EAST OF TUCSON...THROUGH THE WEEKEND AND INTO EARLY NEXT WEEK AT LEAST. && .AVIATION...TAF AND TWEBS ADEQUATELY COVER ALL SIGNIFICANT WEATHER AT KTUS. && .CLIMATE...THE AUGUST CLIMATE REPORT FOR TUCSON HAS BEEN RELEASED AND CAN BE FOUND ON OUR WEBSITE AT (ALL LOWER CASE LETTERS): HTTP://WWW.WRH.NOAA.GOV/TWC/CLIMATE/MONTHLY/AUG05.PHP.
