Area forecast discussion, Jul 12, 2:00 PM MST, 1 hour 25 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TUCSON AZ 200 PM MST THU JUL 12 2012 .SYNOPSIS...ENOUGH MOISTURE FOR ISOLATED TO SCATTERED AFTERNOON AND EVENING THUNDERSTORMS INTO NEXT WEEK. && .DISCUSSION...NO SURPRISES SO FAR THIS AFTERNOON. WESTERN AREAS HAVE BEEN SLOW TO HEAT UP THROUGH THE DECAYING DEBRIS CLOUD. MUCH BETTER SOLAR INSOLATION IN FAR EASTERN AREAS BUT ALSO NOT AS WET AND 12K KTUS SOUNDING WAS SHOWING H5 TEMPERATURES NEAR -5C...A TOUCH WARMER THAN YOU WANT FOR GOOD CONVECTION. SO FAR THIS HAS PROVED FAIRLY ACCURATE AS OF 2 PM WITH ONLY ISOLATED CONVECTION MAINLY SOUTH AND WEST OF TUCSON METRO AREA. THE NICE MOISTURE GRADIENT THROUGH EASTERN PIMA...SANTA CRUZ AND WESTERN COCHISE COUNTY (GOES SOUNDER ESTIMATES IN THE 1.5 TO 1.6 RANGE NEAR EASTERN PIMA DOWN TO ABOUT AN INCH IN NEW MEXICO) HAS INDEED BEEN A FOCUS FOR INITIAL THUNDERSTORM DEVELOPMENT AS EXPECTED...BUT MODEST MID LEVEL TEMPERATURES COMBINED WITH CONTINUED DRYING IN EASTERLY FLOW HASN'T BROUGHT MUCH MORE TO VALLEY LOCATIONS THAN RECENT DAYS. AS THE RIDGE PHASES EASTWARD WE SHOULD SEE MORE COVERAGE THROUGH EASTERN ZONES OVER THE NEXT 72 HOURS. STILL EMPHASIZING WESTERN AREAS FRIDAY...BUT SATURDAY AND SUNDAY WILL SEE ADDITIONAL DEVELOPMENT FURTHER EAST. HOWEVER...THE ORIENTATION OF THE RIDGE AS THE TROUGH DIGS INTO THE PACIFIC NORTHWEST MAY STILL SEE RELATIVELY WARM MID LEVELS AND WEAKER FLOW IN THE SOUTHEAST CORNER OF THE STATE. STILL THINKING THAT LARGE SCALE FEATURES WILL MAKE WAY FOR STRONG DISTURBANCES ROTATING UNDER THE RIDGE IN AN INCREASING SOUTHEASTERLY AND SOUTHERLY FLOW NEXT WEEK. LONG FETCH OF DEEP MOISTURE WITH INVERTED TROUGH APPROACHING THE AREA MONDAY AND TUESDAY. && .AVIATION...SCT-BKN CLOUDS AT 6-9K FT AGL WITH SCT TSRA/SHRA DEVELOPING MAINLY NEAR AND WEST OF A KFHU...TO KTUS...TO KCGZ LINE. WIND GUSTS TO 45 KTS AND MVFR CIGS/VSBYS IN THE VICINITY OF STRONGEST TSRA. DIMINISHING TSRA CHANCES AFT 13/05Z AND IMPROVING CEILINGS. SELY/SLY SURFACE WIND AT 10-15 KTS THRU 13/02Z...WITH SOME AFTERNOON AND EARLY EVENING GUSTS AROUND 20 KTS. SURFACE WIND GENERALLY LESS THAN 10 KTS AFT 13/04Z. AVIATION DISCUSSION NOT UPDATED FOR TAF AMENDMENTS. && .FIRE WEATHER...THERE WILL BE A CHANCE OF SHOWERS AND THUNDERSTORMS THE NEXT SEVEN DAYS...MAINLY DURING THE AFTERNOON AND EVENING HOURS. STRONG...ERRATIC AND GUSTY WINDS WILL BE POSSIBLE WITH ANY OF THE THUNDERSTORMS. EXPECT BREEZY AND GUSTY WINDS DURING THE AFTERNOON AND EARLY EVENING HOURS DUE TO STRONG HEATING...AND MAINLY LIGHT WINDS DURING THE OVERNIGHT AND EARLY MORNING HOURS. && .TWC WATCHES/WARNINGS/ADVISORIES...NONE.
