HIGH TEMPERATURES WILL BE NEAR OR SLIGHTLY ABOVE NORMAL INTO EARLY

.DISCUSSION...KEMX WSR-88D DETECTED SCATTERED 35-55 DBZ ECHOES OVER

STRONGEST CELLS WERE VICINITY SONOITA...PARKER CANYON LAKE...AND THE

KOLS AND NEAR THE FAR SE AZ/SW NM BORDER REGION. CELL MOVEMENT WAS
GENERALLY NW AROUND 10 KTS. THE REST OF SE AZ WAS VOID OF PRECIP
ECHOES. SATELLITE IMAGERY INDICATED CYCLONIC CIRCULATION FEATURE
MOVING NWWD OVER E CENTRAL SONORA.

BASED ON SATELLITE IMAGERY AND RADAR TRENDS...HAVE OPTED TO INCREASE
POPS INTO LOW-CHANCE CATEGORY THIS EVENING FROM THE TUCSON VICINITY
SEWD. GIVEN THE DRIER NEAR-SURFACE ENVIRONMENT...POTENTIAL FOR WIND
GUSTS TO AROUND 45 KTS OR SO MAY OCCUR EARLY THIS EVENING ASSOCIATED
WITH THE STRONGEST TSTMS. OTHERWISE LOCALLY HEAVY RAINFALL ALSO A
THREAT FROM THE STRONGEST CELLS. PER COORD WITH WFO PSR...ALSO OPTED
TO INTRODUCE SLIGHT CHANCE OF SHOWERS/TSTMS AFTER MIDNIGHT ALL ZONES
WITH BELIEF THAT CONVECTIVE COMPLEX DEVELOPS JUST SOUTH OF THIS
FORECAST AREA THIS EVENING.

MOISTURE EXPECTED TO INCREASE ACROSS SE AZ FRI AS GENERALLY SELY
MID-LEVEL FLOW PREVAILS. 09/12Z GFS STILL SIMILAR WITH REGARD TO
PREVIOUS SOLUTIONS IN THAT FRI AND PERHAPS SAT MAY BE A FAIRLY
ACTIVE CONVECTIVE PERIOD. ONE SCENARIO IS FOR LARGE CONVECTIVE
COMPLEXES TO DEVELOP OVER NRN SONORA DURING THE LATE AFTERNOON AND
EVENING PERIODS...AS MENTIONED ABOVE PERHAPS AS EARLY AS THIS
EVENING...WITH CONVECTIVE OUTFLOWS ADVANCING NWD AND SUBSEQUENTLY
PRIMING THIS FORECAST AREA FOR LARGER UPSWING IN CONVECTIVE ACTIVITY
EITHER FRI OR SAT. THUS HAVE TRENDED POPS UPWARD FRI AND SAT INTO
THE CHANCE CATEGORY MAINLY CENTRAL/ERN SECTIONS.

UPPER HIGH TO BE CENTERED OVER THE CENTRAL ROCKIES/CENTRAL CONUS
PLAINS REGION LATER THIS WEEKEND INTO THE MIDDLE OF NEXT WEEK.
09/12Z GFS DEPICTED SOME SEMBLANCE OF INVERTED-TROUGH FEATURE
BRUSHING THE AREA SUN NIGHT FOR POTENTIAL UPSWING IN ACTIVITY. HARD
TO DETERMINE AT THIS TIME THOUGH WHICH DAY...OR DAYS...DURING THE
LATTER PART OF THE FORECAST PERIOD WILL BE POTENTIALLY UP-DAYS...OR
DOWN-DAYS. SO FOR NOW WILL MAINTAIN INHERITED SLIGHTLY BELOW NORMAL
CLIMO POP FORECASTS FOR NOW.

NORMAL THIS WEEKEND INTO EARLY NEXT WEEK.
