NWS Tucson, AZ wrote its last area forecast discussion before the first event at Aug 22, 8:44 PM MST, 3 hours 45 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TUCSON AZ 844 PM MST WED AUG 22 2007 .SYNOPSIS...A WEAK EASTERLY IMPULSE WILL HELP ENHANCE THUNDERSTORM DEVELOPMENT SOUTHEAST OF TUCSON THIS EVENING. EXPECT THE MOISTURE TREND TO BE UP ALONG WITH A LESS STABLE SOUTHERLY FLOW...BRINGING A MUCH BETTER CHANCE OF SHOWERS AND THUNDERSTORMS BY THIS WEEKEND. && .DISCUSSION...LATEST WATER VAPOR IMAGERY SHOWS A RIDGE TO OUR WEST OVER THE NORTHERN BAJA PENINSULA AND ANOTHER HIGH CENTER OVER THE DIXIE STATES. IN BETWEEN THESE TWO HIGHS IS A WEAK INVERTED TROUGH MOVING ACROSS MEXICO WITH A DEFORMATION AXIS OVER SOUTHERN NEW MEXICO AND NORTHERN MEXICO. A TROUGH IS ALSO MOVING BY TO THE NORTH OVER THE CENTRAL AND SOUTHERN ROCKIES. PLENTY OF CONVECTION HAS DEVELOPED WITHIN AND NEAR THE AFOREMENTIONED DEFORMATION ZONE...WITH STORMS EXTENDING FROM SOUTHERN SONORA ACROSS NE SONORA AND INTO SW NEW MEXICO AND NE TOWARD EAST CENTRAL NEW MEXICO AND NORTHERN TEXAS. ISOLATED CONVECTION IS STILL LINGERING WITHIN COCHISE COUNTY. OUTFLOWS FROM THE CONVECTION IN SOUTHWEST NEW MEXICO ARE TRIGGERING DEVELOPMENT WITHIN MY FORECAST AREA. MOST RECENTLY THE STORM NEAR PARADISE AND PORTAL IN EXTREME EAST CENTRAL COCHISE COUNTY SEEMS TO HAVE BEEN TRIGGERED BY OUTFLOWS FROM THE STORMS SOUTH OF LORDSBURG. WITH THE SCATTERED TO NUMEROUS SHOWERS AND STORMS IN NEW MEXICO WILL LEAVE A MENTION OF SHOWERS AND THUNDERSTORMS IN THE GRIDS/ZONES FOR MAINLY COCHISE COUNTY OVERNIGHT. CURRENT FORECAST HAS A 30 PERCENT CHANCE FOR THE EVENING. THIS MAY BE A BIT ON THE HIGH SIDE FOR THE OVERNIGHT HOURS...BUT A SLIGHT CHANCE (10-20%) SEEMS REASONABLE FOR AT LEAST THE REMAINDER OF THE EVENING AND PERHAPS EVEN LINGERING PAST MIDNIGHT. CURRENT FORECAST HAS THIS IDEA...BUT WILL UPDATE THE GRIDS AND ZONES TO FINE TUNE THE WORDING. WILL ALSO MAKE ADJUSTMENTS TO THE REST OF THE FORECAST AREA BASED ON RADAR TRENDS. THE TEMPERATURE FORECAST SEEMS TO BE ON TRACK WITH EXPECTED OVERNIGHT LOWS...BUT WILL ALSO MAKE SOME TWEAKS HERE AND THERE. && .AVIATION...VFR CONDITIONS WILL PREVAIL ACROSS MOST OF THE AREA. THERE WILL BE ISOLATED THUNDERSTORMS EAST AND SOUTH OF TUCSON THIS EVENING...WITH THE BEST CHANCE NEAR DOUGLAS. AVIATION DISCUSSION NOT UPDATED FOR TAF AND TWEB AMENDMENTS. && .PREV DISCUSSION...WITH A LOW FREQUENCY TROUGH DEVELOPING ACROSS NORTHERN AND MID TIER WESTERN STATES OVER THE NEXT 48 HOURS EXPECT A RESULTING WEAKENING IN THE HIGH PRESSURE ACROSS SOUTHERN ARIZONA...WHICH SHOULD HELP OUT WITH A DEGREE OR TWO OF COOLING IN THE MID LEVELS. THIS SHOULD MAKE A DIFFERENCE IN BRINGING THE THUNDERSTORM COVERAGE BACK UP AGAIN ACROSS OUR PORTION OF THE STATE...BUT LIKELY STILL BELOW CLIMO FOR A COUPLE DAYS. DEAN IS CURRENTLY ABOUT 95 MILES NORTHWEST OF MEXICO CITY AND IS NOW A TROPICAL DEPRESSION. AS THE WEAKENING SYSTEM PUSHES ACROSS MEXICO OVER THE NEXT COUPLE OF DAYS THE GREATLY WEAKENED REMNANT MID LEVEL CIRCULATION WILL MOVE TOWARD THE SOUTHERN GULF OF CALIFORNIA. NOT SURE IF THAT CIRCULATION WILL MAKE IT BODILY UP THIS FAR...A LOT DEPENDS ON LARGER SCALE FEATURES THAT COULD BLOCK OR DEFLECT IT TO EITHER SIDE. MOST IMPORTANTLY AN INCREASING SOUTHERLY FLOW SHOULD KEEP MOISTURE PLENTIFUL OR EVEN INCREASE...AND SOME MID LEVEL COOLING SHOULD FURTHER DESTABILIZE THE ATMOSPHERE FOR SCATTERED COVERAGE ON SHOWERS AND THUNDERSTORMS THIS WEEKEND FOR OUR PART OF THE STATE...SHAPING UP TO POSSIBLY ABOVE NORMAL LEVELS WITH THE REMAINS OF DEANS INFLUENCE. && .TWC WATCHES/WARNINGS/ADVISORIES...NONE.
