AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TUCSON AZ 900 PM MST SUN AUG 21 2005 .SYNOPSIS...STRONG HIGH PRESSURE ALOFT WILL REMAIN OVER SOUTHEAST ARIZONA INTO MONDAY...RESULTING IN DRIER AND WARMER CONDITIONS. A SLIGHT CHANCE OF AFTERNOON AND EVENING THUNDERSTORMS WILL STILL EXIST...MAINLY FOR AREAS EAST OF TUCSON. A LOW PRESSURE SYSTEM WILL APPROACH THE AREA BY THE MIDDLE OF THE WEEK. THIS SYSTEM WILL PROVIDE AN INCREASED CHANCE OF SHOWERS AND THUNDERSTORMS ALONG WITH LOWER DAYTIME HIGH TEMPERATURES STARTING TUESDAY. && .DISCUSSION...SOME ISOLATED SHOWERS AND THUNDERSTORMS DEVELOPED EARLIER THIS EVENING...MAINLY OVER THE WHITE MOUNTAINS. LATEST KEMX RADAR INDICATING THUNDERSTORMS FURTHER SOUTH INTO MEXICO AND CENTRAL PORTIONS OF NEW MEXICO. OTHERWISE...ACTIVITY HAS PRETTY MUCH DIED OUT FOR SOUTHEAST ARIZONA. HAVE UPDATED FORECAST TO REDUCE POPS OVERNIGHT IN COCHISE AND KEPT ONLY A SLIGHT CHANCE THROUGH MIDNIGHT IN GRAHAM AND GREENLEE COUNTIES. RATHER DRY FROM 00Z KTUS SOUNDING WITH ONLY MID LEVEL MOISTURE SUSTAINING SOME AFTERNOON SHOWERS AND THUNDERSTORMS. EXPECT SOME SIMILAR CONDITIONS ON MONDAY...WITH INCREASE SHOWER AND THUNDERSTORM POTENTIAL TUESDAY AND WEDNESDAY. THE PREVIOUS DISCUSSION EXPLAINS THE INCREASE. .PREVIOUS DISCUSSION...ISSUED 254 PM MST SUN AUG 21 2005 A DAY SOMEWHAT SIMILAR TO YESTERDAY IS CURRENTLY IN PROGRESS WITH PLENTY OF MID LEVEL DRY AIR OVER MUCH OF SOUTHERN CALIFORNIA AND THE DESERT SOUTHWEST. THE BOUNDARY BETWEEN THIS DRY AIR AND VERY MOIST AIR RESIDES ACROSS NEW MEXICO GENERALLY BISECTING THE STATE FROM THE NE TO THE SW CORNER. MODELS INDICATED THAT THE WEST TO EAST ORIENTED RIDGE AXIS WILL CONTINUE TO RESIDE TO OUR SOUTH. THE UPPER LOW/TROUGH WHICH EXTENDS ACROSS CENTRAL UTAH AND INTO NORTHWEST COLORADO WILL CONTINUE TO LIFT NORTHWARD. BY TOMORROW ANOTHER PACIFIC TROUGH WILL BEGIN TO MAKE ITS WAY ONTO THE WEST COAST IN THE VICINITY OF SOUTH CENTRAL CALIFORNIA AND THE GREAT BASIN. EXPECTING RELATIVELY DRY CONDITIONS THROUGH AT LEAST MONDAY AS THE MID LEVEL DRY AIR REMAINS IN PLACE...SO ONLY EXPECTING ISOLATED TO LOW END OF SCATTERED CATEGORY DURING THE AFTERNOON AND EVENING...MAINLY EAST OF THE TUCSON AREA TO THE NEW MEXICO BORDER...SIMILAR TO TODAY. TO THE WEST NO SHOWERS EXPECTED. BY TUESDAY THE TROUGH SHOULD BE SWINGING THROUGH THE DESERT SOUTHWEST WITH A 35-45 KNOT JET AXIS MOVING ACROSS THE FOUR CORNERS REGION. THIS COULD ENHANCE THE CONVECTION ON TUESDAY...BUT THE LIMITING FACTOR WILL BE THE AMOUNT OF MOISTURE AVAILABLE TO WORK WITH. MOS NUMBERS PAINT A VERY DIFFERENT PICTURE FOR TUESDAY WITH THE GFS BEING THE HIGHEST...SHOWING ABOUT 30 PERCENT FOR TUCSON AND NEARLY 50 FOR DOUGLAS. MEANWHILE THE FWC AND NAM ARE SIMILAR WITH POPS GENERAL 20 PERCENT OR LESS. FOR THE TIME BEING HAVE GONE ABOUT MIDDLE OF THE ROAD WITH GENERALLY 20 PERCENT OR LESS POPS FOR TUCSON AND WESTWARD...AND CLOSE TO 30% TOWARD THE NEW MEXICO BORDER. HAVE GONE WITH MY HIGHEST POP ON WEDNESDAY AS MODELS INDICATE THAT IT IS POSSIBLE THAT SOME MOISTURE FROM HILARY COULD GET SHUNTED NORTH AND EAST AS THE SYSTEM HEADS WEST INTO THE EASTERN PACIFIC. HOWEVER...EVEN SO POP IS ONLY IN THE LOW TO MIDDLE OF THE CHANCE CATEGORY FOR CENTRAL AND EASTERN SECTIONS...AND SLIGHT CHANCE FAR WEST. THEREAFTER MAINLY ISOLATED TO SCATTERED POPS FOR THE REMAINDER OF THE FORECAST PERIOD. TEMPERATURES WILL REMAIN HOT (A FEW TO SEVERAL DEGREES ABOVE NORMAL) THROUGH AT LEAST TUESDAY. ONCE THE TROUGH STARTS WORKING ITS WAY TOWARD OUR AREA AND THE MOISTURE INCREASES...TEMPS SHOULD FALL BACK DOWN INTO THE MIDDLE TO UPPER 90S. && .AVIATION...TAF AND TWEBS ADEQUATELY COVER ALL SIGNIFICANT WEATHER AT KTUS. && .TWC WATCHES/WARNINGS/ADVISORIES...NONE. && WEATHER.GOV/TUCSON
