NWS Tucson, AZ wrote its last area forecast discussion before the first event at Aug 11, 2:23 PM MST, 2 hours 22 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TUCSON AZ 223 PM MST THU AUG 11 2005 .SYNOPSIS...ABUNDANT MOISTURE WILL REMAIN OVER SOUTHEAST ARIZONA FOR THE REMAINDER OF THE WEEK AND INTO THE WEEKEND AS A SOUTHERLY FLOW CONTINUES. EXPECT SCATTERED SHOWERS AND THUNDERSTORMS TO CONTINUE INTO THE WEEKEND BEFORE A SLIGHT DRYING TREND BEGINS TOWARD THE MIDDLE OF NEXT WEEK AS WESTERLY FLOW PREVAILS. && .DISCUSSION...SATELLITE IMAGERY SHOWS THE UPPER LOW SPINNING JUST WEST OF THE CENTRAL BAJA PENINSULA WITH THE RIDGE AXIS EXTENDING FROM THE CENTRAL PLAINS ACROSS NEW MEXICO TO SOUTHEAST ARIZONA. IN BETWEEN THESE TWO SYSTEMS DIFFLUENT FLOW CURRENTLY EXTENDS ACROSS MAINLY CENTRAL ARIZONA INTO WESTERN NEW MEXICO. IN ADDITION THE ACTIVITY IS ALSO BEING ENHANCED BY THE HIGHER ELEVATION ALONG THE RIM COUNTRY. CLOSER TO HOME...A FEW STORMS FIRED EARLIER THIS AFTERNOON IN THE HIGHER TERRAIN WITHIN MY CWA. LOOKING AT THIS MORNINGS SOUNDING WE HAD A SLIGHTLY WARMER LAYER AROUND 700MB...BUT WITH THIS AFTERNOONS DEWPOINT DIPPING INTO THE UPPER 50S IT HAS BEEN A STRUGGLE FOR STORMS TO DEVELOP...WITH THE EXCEPTION OF THE HIGHEST PEAKS WITHIN MY FORECAST AREA. MOSAIC COMPOSITE RADAR SHOWS PLENTY OF ACTIVITY FROM THE FAR WESTERN DESERTS OF THE PHOENIX CWA TO THE RIM COUNTRY OF FLAGSTAFFS AREA TO THE WHITE MOUNTAINS OF MY ZONE 19 (NORTHERN GREENLEE COUNTY). MOST OF THESE STORMS ARE EXHIBITING VERY LITTLE MOVEMENT OR A VERY SLOW NORTHWARD DRIFT. BASED ON THE LATEST RADAR TRENDS I HAVE TRIMMED BACK POPS A BIT FOR THIS EVENING MAINLY FOR SOUTHERN AND EASTERN ZONES...BUT KEPT SLIGHTLY HIGHER POPS FOR THE NORTHERN FRINGES OF MY FORECAST AREA WHERE OUTFLOWS FROM STORMS TO THE NORTH MAY PUSH DOWN INTO THE AREA AND HELP TRIGGER SOME ACTIVITY LATER THIS EVENING. MODELS INDICATE THAT THE UPPER LOW WILL CONTINUE TO SPIN OVER THE REGION...BUT BY THIS WEEKEND IT SHOULD BECOME AN OPEN WAVE AND LIFT TO THE NORTHEAST ACROSS THE DESERT SOUTHWEST. AS THIS OCCURS THE MODELS ARE ADVERTISING A WEAK JET STREAK MOVING ACROSS THE STATE AND AN AREA OF DIFFLUENCE MAY ENHANCE THE ACTIVITY FOR SATURDAY. ON SUNDAY A STRONGER UPPER LOW OVER THE PACIFIC PUSHES TOWARD SOUTHERN CALIFORNIA WITH ANOTHER STRONGER JET MAX MOVING ACROSS ARIZONA FOR A POTENTIAL OF ENHANCED CONVECTION. THE GFS/NAM HAS BEEN ADVERTISING A DRYING TREND FOR THE PAST SEVERAL DAYS WHICH WOULD BEGIN BY AROUND THE EARLY TO THE MIDDLE OF NEXT WEEK. THE OPERATIONAL MEX MOS GUIDANCE IS SHOWING 10 TO 20 PERCENT POPS FOR THE PERIOD FROM MONDAY THROUGH THURSDAY. HOWEVER...THE MEX MOS ENSEMBLE MEMBERS AVERAGE AROUND 35 PERCENT POP FOR EACH DAY THROUGH THAT TIME PERIOD. THEREFORE...I AM NOT CONFIDENT THAT THE DRYING WILL COME IN EARNESTLY...BUT MY GRIDS DO SHOW A SLOW DECREASE IN POPS DURING THE EXTENDED TIME FRAME. SUBSEQUENT SHIFTS CAN MAKE ADDITIONAL ADJUSTMENTS TO THE POP GRIDS IF MODELS CONTINUE TO SHOW THE DRYING TREND. AFTERNOON HIGHS FOR DESERTS/VALLEYS WILL GENERALLY BE IN THE LOWER TO MID 90S THROUGH THE WEEKEND...BUT WILL INCREASE SLIGHTLY INTO THE MID TO UPPER 90S FOR THE REMAINDER OF THE FORECAST PERIOD. && .AVIATION...TAF AND TWEBS ADEQUATELY COVER ALL SIGNIFICANT WEATHER AT KTUS. && .TWC WATCHES/WARNINGS/ADVISORIES...NONE. && MOLLERE WEATHER.GOV/TUCSON
