UNSEASONABLY COLD STORM SYSTEM WILL BRING THREAT OF SHOWERS AND THUNDERSTORMS TO SOUTHWEST CALIFORNIA TODAY THROUGH FRIDAY...

A COLD...WINTER-LIKE STORM SYSTEM WILL DIVE SOUTHWARD INTO CALIFORNIA TODAY THROUGH FRIDAY. A SLIGHT CHANCE OF SHOWERS WILL DEVELOP ACROSS PORTIONS OF SOUTHWEST CALIFORNIA THIS MORNING. AS THE MAIN LOW PRESSURE SYSTEM DRAWS CLOSER TO THE REGION...THERE WILL BE AN INCREASED THREAT OF SHOWERS FROM THIS AFTERNOON THROUGH FRIDAY
EVENING. DURING THIS TIME...THERE WILL ALSO BE A SLIGHT CHANCE OF THUNDERSTORMS CAPABLE OF PRODUCING BRIEF HEAVY DOWNPOURS AND SMALL HAIL. THESE THUNDERSTORMS MAY IMPACT THE RUSH HOUR COMMUTES FROM THIS EVENING THROUGH FRIDAY EVENING. IN ADDITION...CONDITIONS WILL
BE FAVORABLE FOR ISOLATED WATERSPOUTS ACROSS THE COASTAL WATERS.

RAINFALL AMOUNTS WITH THIS SYSTEM WILL BE QUITE VARIABLE DUE TO THE SHOWERY NATURE OF THE EXPECTED PRECIPITATION...AND SOME AREAS MAY NOT EXPERIENCE ANY RAINFALL AT ALL. IN GENERAL...RAINFALL AMOUNTS ARE EXPECTED TO BE LESS THAN ONE QUARTER INCH. HOWEVER...WITH ANY THUNDERSTORMS THAT DEVELOP...LOCAL AMOUNTS AROUND ONE HALF INCH WILL BE POSSIBLE. THE SHOWERS ASSOCIATED WITH THUNDERSTORMS COULD PRODUCE
MINOR MUD AND DEBRIS FLOWS IF THE STORM WERE TO MOVE OVER A RECENT BURN AREA.

COLD AIR...ASSOCIATED WITH THE STORM SYSTEM...WILL ALSO BRING LOW SNOW LEVELS. BY LATE THIS AFTERNOON...SNOW LEVELS ARE EXPECTED TO FALL TO AROUND 6000 FEET. FOR TONIGHT AND INTO FRIDAY MORNING...THESNOW LEVELS WILL DROP EVEN FURTHER...DOWN TO AROUND 4500 FEET.
SO...DEPENDING ON THE AMOUNT OF SHOWER ACTIVITY...THERE MAY BE SOME LIGHT SNOW ACCUMULATIONS IN THE LOCAL MOUNTAINS.

ADDITIONALLY...THERE WILL BE SOME GUSTY SOUTHWESTERLY WINDS ACROSS THE ANTELOPE VALLEY THIS AFTERNOON AND EVENING....WITH WIND GUSTS TO AROUND 45 MPH EXPECTED.

RESIDENTS OF SOUTHWEST CALIFORNIA SHOULD MONITOR THE LATEST NATIONAL WEATHER SERVICE PRODUCTS FOR THIS DEVELOPING WEATHER SITUATION. ANYONE PLANNING TO TRAVEL TO THE LOCAL MOUNTAINS SHOULD PREPARE FOR THE POSSIBILITY OF SNOW SHOWERS AND GUSTY WINDS.
