AZZ020>028-CAZ030>033-020600- AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PHOENIX AZ 245 PM MST MON AUG 1 2005 SOUTHWEST AND SOUTH-CENTRAL ARIZONA...AND SOUTHEAST CALIFORNIA FORECAST DISCUSSION .SYNOPSIS... A MOIST FLOW OF AIR WILL REMAIN IN PLACE ACROSS ALL OF ARIZONA AND SOUTHEAST CALIFORNIA THIS WEEK. MINOR WEATHER DISTURBANCES MOVING ACROSS THE REGION...WILL HELP TO CREATE SCATTERED SHOWERS AND THUNDERSTORMS OVER THE REGION THIS EVENING...LESS NUMEROUS OVER THE LOWER DESERTS. A SLIGHT DECREASE IN STORM ACTIVITY IS ANTICIPATED BEGINNING WEDNESDAY. HOWEVER...THERE WILL BE AT LEAST A SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS A JUST ABOUT EVERY AFTERNOON AND EVENING THROUGH THE WEEKEND. LITTLE DAY-TO-DAY TEMPERATURE VARIATION IS EXPECTED INTO NEXT WEEK. && .DISCUSSION... STORMS HAVE STARTED EARLY ON THE LOW DESERTS IN SOUTHWEST ARIZONA. WE HAVE ALREADY HAD SOME STRONG BUT ISOLATED STORMS OVER YUMA COUNTY. STORMS HAVE ALSO BEEN GOING UP AND DOWN OVER JOSHUA TREE. THE BAND OF CLOUDINESS THAT WAS OVER SOUTH-CENTRAL ARIZONA THIS MORNING HAS PRETTY MUCH DISSIPATED WHICH SHOULD HELP THE INSTABILITY CAUSE. EASTERN ARIZONA IS NOT VERY ACTIVE YET. THOUGH THERE ARE A FEW STORMS...WOULD HAVE EXPECTED TO SEE MORE MORE VIGOROUS STORM ACTIVITY THERE THAN IN YUMA COUNTY. AIR IS MORE MOIST IN SOUTHWEST ARIZONA THOUGH. AS PREVIOUSLY DISCUSSED...THERE ARE FLOW FEATURES ALOFT WHICH WILL HELP THE STRENGTH OF CONVECTION OVER MUCH OF OUR FORECAST AREA TODAY...LESS SO TUESDAY. AREAS CLOSEST TO HIGHER TERRAIN STILL STAND A BETTER CHANCE. ONE LIMITING FACTOR FOR TODAY IS THAT THE TEMPERATURE PROFILES ARE NOT OUTSTANDING FOR BIG CAPE. SO ONCE AGAIN...POTENTIAL FOR STRONG STORMS EXISTS OVER A LARGE AREA...BUT THEY WILL TEND TO BE ISOLATED. INFACT...IT WILL BE UNLIKELY THAT A MAJORITY OF THE FORECAST AREA EXPERIENCES WETTING RAIN. THE STORMS WILL TEND TO FAVOR RAIN PRODUCTION OVER WIND PRODUCTION. HOWEVER...THE STRONG ONES WILL BE CAPABLE OF PRODUCING BOTH. FROM MIDWEEK INTO THE WEEKEND...THE GFS IS INDICATING THAT THE STEERING FLOW WILL HAVE AN EASTERLY COMPONENT TO THE STEERING FLOW WHICH COULD HELP WITH STORM DEVELOPMENT OVER SOUTH-CENTRAL ARIZONA. HOWEVER...IT IS ALSO INDICATING LESS OVERALL MOISTURE. THIS IS REFLECTED IN SOMEWHAT LOWER POPS. PREVIOUS FORECAST TRENDS ARE STIL ON TRACK WITH A LOT OF MINOR TWEAKS TO THE POPS. && .AVIATION... DISCUSSION FOR 00TAFS. TAFS FOR KPHX...KIWA...KYUM...KIPL...AND KBLH ADEQUATELY DESCRIBE EXPECTED WEATHER CONDITIONS. AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS. && .PSR WATCHES/WARNINGS/ADVISORIES... AZ...NONE. CA...NONE. AJ NATIONAL WEATHER SERVICE PHOENIX IS ON THE INTERNET AT WEATHER.GOV/PHOENIX
