AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TUCSON AZ 905 AM MST TUE MAY 24 2005 .SYNOPSIS...A STRONG HIGH PRESSURE SYSTEM ALOFT WILL BRING RECORD OR NEAR RECORD HIGH TEMPERATURES TO MUCH OF SOUTHEAST ARIZONA AGAIN THIS AFTERNOON. OTHERWISE...DRY WEATHER WILL PREVAIL ACROSS THE AREA THROUGH THURSDAY. THE UPPER HIGH WILL WEAKEN LATER THIS WEEK...WITH SOME MODERATION IN DAYTIME HIGH TEMPERATURES ESPECIALLY BY THE WEEKEND. && .DISCUSSION...MOSTLY CLEAR SKIES ACROSS THE STATE TODAY..EXCEPT A FEW MID AND HIGH LEVEL CLOUDS IN NEW MEXICO. A BIT MORE MOISTURE SEEPAGE INTO THE AREA...AS DEW POINT TEMPERATURES RANGE INTO THE UPPER 40S AND MID 50S ACROSS SOUTHERN PORTIONS OF THE CWA. THERE WAS CONCERN THAT TUCSON DEW POINT GAGE WAS HAVING ERRORS EARLIER IN THE WEEKEND...PARTICULARLY WHEN DAVIS MONTHAN WAS NOT INDICATING THE HIGHER DEW POINT TEMPERATURES. HOWEVER...THIS SEEPAGE OF MOISTURE IS DEFINITELY REALISTIC AS DAVIS MONTHAN ALSO SHOWS DEW POINTS IN LOWER 50S. ALSO NOT TO MENTION THAT DEW POINTS ACROSS THE ENTIRE CWA SHOW AN INCREASE OF 10 TO 15F DEGS...WITH THE MOST NOTICEABLE OF 20F INCREASE AT NOGALES. 12Z KTUS SOUNDING SHOWED THE INCREASE IN MOISTURE PARTICULARLY IN THE LOWER LEVELS OF THE ATMOSPHERE...WITH PRECIPITABLE WATER VALUE OF 0.90 INCHES COMPARED TO 0.63 YESTERDAY MORNING. THE SHOWERS AND THUNDERSTORMS THAT DEVELOPED YESTERDAY APPEARED TO MOVING ALONG THE 500MB DEW POINT DEPRESSION...WHICH WAS FORECASTED TO SHIFT EASTWARD TODAY. HOWEVER...AFTER VIEWING THE MOISTURE INCREASE IN THE MORNING SOUNDING THE MIDNIGHT SHIFT DECIDED TO UPDATE THE FORECAST TO REFLECT SLIGHT CHANCE OF SHOWERS AS FAR NORTH AS EASTERN PIMA COUNTY. ALTHOUGH DO NOT EXPECT ANY TYPE OF DOWNPOURS...THIS WAS A GOOD MOVE FOR THE POSSIBILITY OF SOME SPRINKLES OR EVEN A COUPLE HUNDREDTHS OF RAINFALL DUE TO THE INCREASED MOISTURE. ALSO EXPECT ANOTHER DAY OF RECORD TO NEAR RECORD TEMPERATURES ACROSS THE CWA. THIS MORNING WE ALSO HAD RECORD HIGH MINIMUM TEMPERATURE AT TUCSON INTERNATIONAL AIRPORT WITH 76F DEGS BREAKING THE OLD RECORD OF 73F DEGS SET IN 1990. ANOTHER RECORD HIGH MINIMUM TEMPERATURE WAS ALSO SET AT NOGALES WITH 76F DEGS BREAKING THE OLD RECORD OF 60F DEGS SET IN 2003. RIDGE WILL BEGIN TO WEAKEN...FINALLY DROPPING TEMPERATURES TO BELOW RECORD OR NEAR RECORD VALUES. FORECAST LOOKS GOOD...NO UPDATES NECESSARY. && .FIRE WEATHER...RELATIVE HUMIDITY VALUES INCREASED BY AS MUCH AS 15 PERCENT AS MID AND LOWER LEVEL MOISTURE PUSHED NORTHWARD INTO SOUTHERN ARIZONA. WITH THE INCREASED MOISTURE EXPECT SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS TO DEVELOP AS FAR NORTH AS TUCSON. HOWEVER...ONLY EXPECTING SPRINKLES UP TO A COUPLE HUNDREDTHS OF AN INCH OF RAINFALL. DEEP MIXING WILL SUPPORT AFTERNOON UPSLOPE GUSTINESS AND 5-6 HAINES INDICES THROUGH WEDNESDAY. THE UPPER HIGH PRESSURE SYSTEM WILL START TO WEAKEN BY THURSDAY. THIS WILL ALLOW INCREASED GRADIENT WIND FROM THE WEST AS WELL AS SLIGHTLY HIGHER RELATIVE HUMIDITIES AS TEMPS COOL AND SOMEWHAT BETTER MOISTURE SEEPAGE FROM SONORA. WILL CONTINUE WITH SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS FOR EASTERN ZONES FRI AFTERNOON AND EVENING. && .CLIMATE...ONE MORE DAY OF RECORD OR NEAR RECORD SETTING TEMPERATURES ACROSS SOUTHEAST ARIZONA THIS AFTERNOON. HOWEVER...THE TUCSON INTERNATIONAL AIRPORT ONLY REACHED 105 DEG F YESTERDAY... WHICH IS 1 DEG SHY OF THE RECORD FOR THE DATE. TODAYS RECORD FOR TUCSON IS 104 DEG F AND THE FORECAST IS CALLING FOR THE SAME. HOWEVER...WE DID BREAK SOME MORNING MINIMUM TEMPERATURES AS TUCSON INTERNATIONAL AIRPORT RECORDED 76F DEGS BREAKING 73F DEGS SET IN 1990. ANOTHER RECORD HIGH MINIMUM TEMPERATURE WAS ALSO SET AT NOGALES WITH 76F DEGS BREAKING THE OLD RECORD OF 60F DEGS SET IN 2003.
