Area forecast discussion, Aug 5, 2:20 PM MST, 1 hour 58 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TUCSON AZ 220 PM MST SUN AUG 5 2012 .SYNOPSIS...SCATTERED THUNDERSTORMS THIS EVENING AND MONDAY BEFORE A MODEST DRYING TREND WILL SEE LESS THUNDERSTORM COVERAGE FOR MUCH OF THE WEEK. STRONG HIGH PRESSURE WILL BRING HOTTER TEMPERATURES. && .DISCUSSION...A COUPLE OF MESOSCALE CONVECTIVE VORTICES EMBEDDED IN THE SOUTHERLY FLOW WERE COMPLICATING THE FORECAST FOR TODAY. THE FIRST MCV WAS LIFTING NORTHWARD THROUGH CENTRAL ARIZONA...WITH SUBSIDENCE IN ITS WAKE OVER SOUTHEAST ARIZONA. THIS SUBSIDENCE HELPED CLEAR SKIES ACROSS THE AREA THIS MORNING...WITH SHALLOW CUMULUS CLOUDS NOW STARTING TO FORM EARLY THIS AFTERNOON WITH THE SURFACE HEATING KICKING IN. THE OTHER MCV WAS CENTERED OVER SONORA MEXICO SOUTH OF AJO. THIS FEATURE WAS ALSO LIFTING NORTHWARD AND APPEARED TO BE AIDING IN THE DEVELOPMENT OF CLOUDS OVER CENTRAL AND WESTERN PIMA COUNTY. THESE TWO FEATURES COMBINED WITH THE INFLUENCES OF AN INVERTED TROUGH PASSING THROUGH NORTHERN MEXICO POSE SOME UNCERTAINTIES FOR THIS EVENING AND TONIGHT. THE CURRENT THINKING WAS THAT THE SUBSIDENCE WILL WEAKEN AS THE MCV OVER CENTRAL ARIZONA TRACKS FARTHER NORTH. AS THIS HAPPENS...SHOULD START TO SEE THE INFLUENCE OF THE INVERTED TROUGH AND THE SECOND MCV COMING TOGETHER TO AID IN THE DEVELOPMENT OF THUNDERSTORMS LATE THIS EVENING. ALSO EXPECTING THE INVERTED TROUGH TO HELP FORM ANOTHER MCS OVER NORTHERN MEXICO THAT WILL SEND OUTFLOW INTO SOUTHERN ARIZONA TRIGGERING MORE SHOWERS OVERNIGHT TONIGHT. THEREAFTER...HIGH PRESSURE ALOFT BUILDS WESTWARD THROUGH MID WEEK. THIS WILL CHOKE OFF THE DEEPER MOISTURE ONCE AGAIN...AND STABILIZE THE AIRMASS WITH WARMING ALOFT. AS A RESULT...LIMITED THUNDERSTORM ACTIVITY WILL BE FORECAST AFTER TUESDAY WITH HIGH TEMPERATURES REMAINING ABOVE NORMAL. && .AVIATION...SCT-BKN 100-120. WIND SPEEDS GENERALLY LESS THAN 10 KTS. ISOLD-SCT TSRA DVLPG THRU 06/16Z...WITH WIND GUSTS TO 40 KTS NEAR THE THUNDERSTORMS. AVIATION DISCUSSION NOT UPDATED FOR TAF AMENDMENTS. && .FIRE WEATHER...SHOWERS AND THUNDERSTORMS WILL CONTINUE TO BE POSSIBLE THRU THE WEEK...THOUGH MAIN STORY WILL BE THE DRYING AND WARMING TREND EXPECTED. THIS WILL RESULT IN RH VALUED CONTINUING TO DROP BELOW VALUES SEEN OVER THE LAST FEW WEEKS. WINDS WILL ALSO INCREASE SLIGHTLY LATE IN THE WEEK AS THE UPPER LEVEL HIGH REPOSITIONS OVER NRN AZ. && .TWC WATCHES/WARNINGS/ADVISORIES...NONE. WEATHER.GOV/TUCSON
