A LOW PRESSURE SYSTEM WILL CONTINUE OVER THE WESTERN STATES...MAINLY NORTH OF ARIZONA INTO THE LABOR DAY WEEKEND. MONSOON MOISTURE OVER THE EASTERN ARIZONA WILL PROVIDE A CHANCE FOR MOUNTAIN THUNDERSTORMS INTO EARLY NEXT WEEK. HIGH PRESSURE IS FORECAST TO REBUILD OVER THE WESTERN STATES BY NEXT TUESDAY...PROVIDING WARMER AFTERNOONS. .DISCUSSION... A LARGE TROF CONTINUED TO CIRCULATE OVER THE WESTERN STATES... CENTERED JUST SOUTHWEST OF BOISE ID AT 08Z. A RATHER SHARP EMBEDDED SHORTWAVE/VORT MAX WAS SEEN ROTATING AROUND THE BASE OF TROF AND INTO WESTERN AZ...PROVIDING DYNAMICS FOR A CONTINUATION OF THUNDER STORMS IN EAST CENTRAL AND SOUTHEAST AZ AT THE MOMENT (08Z). SECONDARY CIRCULATIONS OR AGEO-STROPHIC FLOW REALLY SURGED THE MONSOON MOISTURE NORTH FROM MEXICO ON WEDNESDAY...AND REGIONAL SOUNDINGS AND PLOT DATA SHOWED A DEEP PLUME OF LOW LEVEL MOISTURE CONTINUES ALONG AN AXIS FROM JUST NORTH OF PHOENIX TO TUCSON. FORECASTS FOR PARTS OF THE SOUTH CENTRAL DESERTS WILL BE TRICKY TODAY...MAINLY BECAUSE WE ARE NOT SURE WHERE THE ENTRANCE REGION OF THE JET MAX WILL BE POSITIONED...AS THE SHORTWAVE (CURRENTLY MOVING INTO WESTERN AZ) EXITS THE STATE INTO SOUTHWEST COLORADO THIS AFTERNOON. MODELS SEEM TO INDICATE THE JET MAX ENTRANCE REGION WILL BE LOCATED OVER THE WHITE MOUNTAINS AND PARTS OF SOUTHEAST AZ... HOWEVER IT COULD EXTEND WEST INTO PARTS OF THE SOUTH CENTRAL DESERTS. THEREFORE WITH ABUNDANT MONSOON MOISTURE...WE WILL INCLUDE A SLIGHT CHANCE FOR THUNDERSTORMS ON THE SOUTH CENTRAL DESERTS... WITH A BETTER CHANCE IN THE MOUNTAINS OF ZONE 24 INTO THE EVENING HOURS. FLOW ALOFT BECOMES MORE LAMINAR FROM THE SOUTHWEST FRIDAY AND THE WEEKEND WITH NO SHORTWAVE ACTIVITY. MOISTURE VALUES THIN A LITTLE OVER THE WEEKEND...HOWEVER THERE ARE SOME HINTS OF AN UPPER LEVEL DEFORMATION ZONE DEVELOPING OVER THE WHITE MOUNTAINS AND PARTS OF SOUTHEAST AZ SATURDAY AFTERNOON (FOR POSSIBLE ENHANCED CONVECTIVE ACTIVITY). THEREFORE WE WILL CONTINUE A SLIGHT CHANCE FOR THUNDERSTORMS OVER OUR MOUNTAINOUS ZONE 24 FRIDAY AND THE WEEKEND. THE AIRMASS COULD DRY OUT SOMEWHAT NEXT WEEK...HOWEVER WE WILL NOT REMOVE THUNDERSTORM THREATS OVER ZONE 24. VASQUEZ .PSR...NONE.
