SOUNDING HAS MATERIALIZED THIS AFTERNOON WITH STORMS INITIATING OVER
THE MOUNTAINS AND MOVING SOUTH. ALTHOUGH HEAVY RAIN AND SOME HAIL
HAS BEEN EVIDENT WITH THESE STORMS...THEY HAVE BEEN FAIRLY SHORT
LIVED DUE TO THE UNFAVORABLE VERTICAL WIND PROFILE. CAPE VALUES OVER
1500 J/KG STILL OVER MUCH OF MOHAVE AND SOUTHEAST SAN BERNARDINO
COUNTIES SHOULD PROVIDE AMPLE OPPORTUNITY FOR STORM SUPPORT THROUGH
THIS EVENING. SOME STABILIZATION IS INDICATED FRIDAY AS DRIER
SOUTHWEST FLOW SPREADS EAST FROM SOUTHERN CALIFORNIA. DEWPOINTS WERE
IN THE MID 40S AT DAGGETT AND TWENTYNINE PALMS. STILL EXPECT
CONVECTION OVER THE HIGHER TERRAIN OF SOUTHERN NEVADA AND NORTHWEST
ARIZONA TO DEVELOP AND MOVE TO THE EAST OR SOUTHEAST ON FRIDAY. A
WEAK LOW OFF THE WEST COAST...WHICH IS APPARENT ON WATER VAPOR
IMAGERY...BEGINS TO APPROACH THE SOUTHERN CALIFORNIA COAST SATURDAY
ACCORDING TO THE GFS. ALTHOUGH IT IS PRECEDED BY WEAK SOUTHWEST
FLOW...DO NOT SEE MUCH CHANGE BETWEEN FRIDAY AND SATURDAY IN
PLACEMENT OR COVERAGE OF THUNDERSTORMS. SUNDAY COULD BE MORE
FAVORABLE TO BRING ADDITIONAL MOISTURE AND BROAD UPWARD FORCING TO
THE FORECAST AREA IF THE LOW CENTER SETS UP NEAR SAN DIEGO.

.LONG TERM...MODELS PERSIST PERSIST IN SLOWLY EJECTING THE SOUTHWEST
OF SAN DIEGO CALIFORNIA LOW ON SUNDAY AND MONDAY AND ACCOMPANY IT
WITH SOME MOISTURE AS WELL. HAVE UPPED THE POPS SUNDAY AND MONDAY.
STILL LOOK FOR DRYER WESTERLY FLOW TO BE GOING ON FROM TUESDAY
ONWARDS. HAVE A DRYING TREND GOING FROM WEST TO EAST NEXT WEEK. HAVE
KEPT INHERITED POPS IN FOR TUESDAY AND WEDNESDAY AND HAVE THE CWA
DRY ON THURSDAY. MADE MINOR TWEAKS IN TEMPERATURES AS OPERATIONAL
AND ENSEMBLE MEAN GUIDANCE SHOW COOLER TEMPERATURES IN THE EXTENDED.
