Area forecast discussion, Jun 26, 1:33 PM MST, 1 hour 54 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TUCSON AZ 133 PM MST TUE JUN 26 2012 .SYNOPSIS...SUFFICIENT MOISTURE FOR ISOLATED TO SCATTERED AFTERNOON AND EVENING THUNDERSTORMS INTO THIS EVENING. EXPECT LESS STORM ACTIVITY STARTING WEDNESDAY BUT ESPECIALLY THURSDAY AND INTO THE WEEKEND AS HIGH PRESSURE BUILDS OVERHEAD ACCOMPANIED BY HOTTER TEMPERATURES. && .DISCUSSION...LATEST RADAR IMAGERY SHOWS ISOLATED STORMS HAVE NOW STARTED TO GET GOING OVER THE PAST COUPLE OF HOURS PRIMARILY OVER THE HIGHER TERRAIN TO THE SOUTH AND EAST OF TUCSON. THEY HAVE STRUGGLED A LITTLE BIT INITIALLY...BUT AS DAYTIME HEATING CONTINUES...THE STORMS SHOULD BE ABLE TO BETTER WORK THROUGH RESIDUAL INHIBITION. WITH THAT SAID...LEANED TOWARDS THE UOFA WRF SOLUTIONS TODAY WHICH BOTH DEPICT CONVECTION GETTING MORE ORGANIZED AS THE AFTERNOON PROGRESSES WITH THE STORMS PUSHING NNW OFF THE MOUNTAINS INTO VALLEY LOCATIONS. THIS HAS BEEN PARTICULARY OCCURRING OVER THE PAST 30 MINUTES OR SO AS STORMS HAVE DEVELOPED JUST TO THE SOUTH AND EAST OF TUCSON. WE CONTINUE TO BE CONCERNED ABOUT GUSTY OUTFLOW WINDS FROM THESE STORMS WHICH COULD PRODUCE BLOWING DUST MAINLY TO THE NORTH AND WEST OF TUCSON. OTHERWISE...WITH SCATTERED STORMS...EXPECT SOME LOCALLY HEAVY RAINFALL AND GUSTY WINDS. MOISTURE WILL GRADUALLY DECREASE WEDNESDAY ACROSS THE REGION WITH PRECIPITABLE WATER VALUES DOWN CLOSER TO 1 INCH AS HIGH PRESSURE BUILDS INTO THE REGION. THIS WILL STILL BE ENOUGH MOISTURE TO RESULT IN A SLIGHT CHANCE OF THUNDERSTORMS. THEREAFTER...AS HIGH PRESSURE BUILDS IN...MOISTURE WILL CONTINUE TO DECREASE WITH VERY LITTLE CHANCE OF STORMS. THE MAIN STORY DURING THURSDAY AND CONTINUING INTO THIS WEEKEND WILL BE THE VERY HOT TEMPERATURES WITH HIGHS AT OR ABOVE 110 POSSIBLE IN THE LOWER DESERTS WHERE A HEAT ADVISORY MAY NEED TO BE ISSUED BY LATER SHIFTS. BY EARLY NEXT WEEK...EXPECTING TO SEE A RETURN OF SOME MOISTURE AS THE HIGH PRESSURE RIDGE BREAKS DOWN AND ALLOWS AN INCREASE OF MOISTURE AND A BETTER CHANCE OF THUNDERSTORMS. && .AVIATION...SCT TSRA/SHRA THRU THIS EVENING THEN BULK OF PRECIP TO END BY 27/06Z. WIND GUSTS OF 40-45 KTS PRODUCING LOCAL BLDU WITH VSBYS 1-3SM. OTHERWISE...CLOUD DECKS AT 7-12K FT AGL INTO THIS EVENING THEN FEW-SCT CLOUDS MOSTLY ABOVE 12K FT AGL LATE TONIGHT AND WEDNESDAY MORNING. ISOLD-SCT TSRA/SHRA MAINLY EAST AND SOUTH OF KTUS WEDNESDAY AFTERNOON. SURFACE WIND GENERALLY LESS THAN 10 KTS THRU WEDNESDAY AFTERNOON. AVIATION DISCUSSION NOT UPDATED FOR TAF AMENDMENTS. && .FIRE WEATHER...EXPECT SCATTERED THUNDERSTORMS THROUGH THIS EVENING FOLLOWED BY ISOLATED TO SCATTERED THUNDERSTORMS MAINLY EAST AND SOUTH OF TUCSON WEDNESDAY AFTERNOON AND WEDNESDAY EVENING. STRONG...ERRATIC AND GUSTY WINDS WILL OCCUR WITH THE THUNDERSTORM OUTFLOWS. A GRADUAL DRYING TREND IS ON TAP DURING THE LATTER PART OF THE WEEK AND THIS WEEKEND. THERE WILL STILL BE ENOUGH MOISTURE FOR A SLIGHT CHANCE OF AFTERNOON AND EVENING THUNDERSTORMS ACROSS THE HIGHER TERRAIN EAST OF TUCSON FRIDAY THROUGH SUNDAY. THEREAFTER... SCATTERED MAINLY AFTERNOON AND EVENING THUNDERSTORMS ARE EXPECTED TO RETURN BY NEXT TUESDAY AS MOISTURE INCREASES ACROSS THE AREA. OTHERWISE...NORMAL DIURNAL WIND TRENDS WILL OCCUR WITH OCCASIONAL GUSTS DURING THE AFTERNOON AND EARLY EVENING HOURS. && .CLIMATE...ANOTHER WARM MORNING IN TUCSON WITH A LOW OF 83 DEGREES WHICH MEANS FOR THE THIRD CONSECUTIVE DAY...THE DAILY RECORD HIGH MINIMUM TEMPERATURE WILL BE THREATENED. THE RECORD HIGH MINIMUM FOR JUNE 26TH IS 82 DEGREES....WHICH WAS SET IN 2002. && .TWC WATCHES/WARNINGS/ADVISORIES...NONE. WEATHER.GOV/TUCSON
