...THREAT OF MONSOONAL THUNDERSTORMS LATE TONIGHT THROUGH WEDNESDAY...

A STRONG UPPER LEVEL HIGH PRESSURE SYSTEM CURRENTLY CENTERED OVER NEVADA
WILL BRING INCREASING EAST TO SOUTHEAST FLOW OVER SOUTHERN
CALIFORNIA. AS A RESULT...A SIGNIFICANT SURGE OF MONSOONAL MOISTURE
WILL MOVE INTO SOUTHWEST CALIFORNIA LATE TONIGHT THROUGH WEDNESDAY.
THE GREATEST THREAT OF SHOWERS AND THUNDERSTORMS WILL BE ACROSS THE
MOUNTAINS AND ANTELOPE VALLEY LATE TONIGHT INTO TUESDAY. DUE TO THE
EASTERLY UPPER LEVEL FLOW ON MONDAY...THERE WILL ALSO BE A SLIGHT
CHANCE OF SHOWERS AND THUNDERSTORMS ACROSS MOST COASTAL AND VALLEY
AREAS.

THE DEEPER MONSOONAL MOISTURE WILL BRING THE POTENTIAL FOR BRIEF HEAVY
RAINFALL WITH STORMS THAT DEVELOP ON MONDAY AND TUESDAY...ESPECIALLY
ACROSS THE MOUNTAINS AND ANTELOPE VALLEY. WHILE STORMS ARE EXPECTED
TO BE FAST MOVING...THERE WILL BE THE POTENTIAL FOR LOCALIZED FLOODING
OF ROADWAYS AND ARROYOS. ON TUESDAY...THE THREAT OF THUNDERSTORMS IS
EXPECTED TO REMAIN CONFINED TO THE MOUNTAINS AND DESERTS. WITH WEAKER
UPPER LEVEL WINDS ON TUESDAY...STORMS WILL LIKELY MOVE SLOWER. AS A
RESULT...THERE WILL BE AN INCREASED THREAT OF FLASH FLOODING.

IT WILL NOT BE AS HOT ACROSS MUCH OF THE REGION TOMORROW DUE TO THE
INCREASED MOISTURE AND CLOUD COVERAGE...WITH INTERIOR SECTIONS
GENERALLY REMAINING IN THE 90S. HOWEVER...THERE WILL BE A
SIGNIFICANT INCREASE IN HUMIDITY ON MONDAY THAT WILL CONTINUE TO
BRING DISCOMFORT.

ANYONE PLANNING OUTDOOR ACTIVITIES IN THE MOUNTAINS AND DESERTS
DURING THE NEXT FEW DAYS SHOULD CAREFULLY MONITOR THE LATEST
NATIONAL WEATHER SERVICE FORECASTS AND STATEMENTS DUE TO THE
POTENTIAL HAZARDS ASSOCIATED WITH THUNDERSTORMS.


Showers and thunderstorms are possible across area mountains and the Antelope Valley today through Wednesday with a slight chance of the storms affecting coastal and valley areas today. These storms bring a potential for localized flooding of roadways and arroyos and a slight chance of flash flooding in the mountains today and Tuesday. People planning outdoor activities in the mountains and deserts during the next few days should closely monitor the latest National Weather Service forecasts and statements due to the potential hazards associated with thunderstorms.
