UPR LOW SPINNING PRETTY MUCH IN PLACE SOUTH OF SAN NICHOLAS ISLAND.
SURPRISINGLY THE MOST ACTIVITY HAS BEEN IN THE SBA CHANNEL WHERE
NUMEROUS LIGHTNING STRIKES HAVE BEEN DETECTED AND EVEN THE AIRPORT
REPORTED TS FOR A WHILE EARLIER TODAY. TOUGH TO PICK OUT ANY ORGANIZED
VORT MAXES ON SAT IMAGERY SO WILL HAVE TO JUST BLANKET MOST OF THE
FORECAST AREA WITH A SCATTERED SHOWERS AND A CHANCE OF THUNDERSTORMS
THROUGH AT LEAST THE EARLY PART OF SAT. 12Z MODELS ALL INDICATE LOW
SHOULD BE FAR ENOUGH OUT OF THE AREA BY SAT AFTN THAT MOST OF THE
SHOWERS SHOULD BE OVERWITH IN OUR CWA. UNTIL THEN...AIRMASS IS QUITE
UNSTABLE AND JUST ABOUT ANYWHERE IN THE CWA COULD GET A SHOWER OR
THUNDERSTORM.
DESPITE LOW MOVING OUT OF THE AREA SAT...THERE SHOULD BE ENOUGH
RESIDUAL MOISTURE AROUND FOR AT LEAST PARTLY CLOUDY SKIES THROUGH THE
AFTN. SHOULD SEE A SLIGHT WARMUP WITH A LITTLE MORE SUN BUT NOTHING
DRAMATIC.
NEXT SYSTEM IS CLOSE ON THE HEELS AND WILL BEGIN SPREADING RAIN TO THE
CENTRAL COAST SAT NIGHT AND INTO THE LA BASIN SOMETIME SUNDAY. TIMING
IS STILL SOMEWHAT UNCERTAIN SO DECIDED TO NOT MAKE ANY SPECIFIC
REFERENCES TO TIMING OF RAIN IN THE ZONES. ALSO A LITTLE CONCERNED THAT
THE LOW WILL MOVE TOO FAR WEST OF OUR AREA. HOWEVER...THE ONE THING
THAT DOES LOOK CERTAIN IS THAT THE WEEKEND STORM WILL BE VERY COLD WITH
SNOW LEVELS LOWERING TO BETWEEN 2500 AND 3000 FEET BY MONDAY MORNING.
THIS WOULD BE A CONCERN FOR CERTAINLY THE MOUNTAIN PASSES AND POSSIBLY
EVEN THE ANTELOPE VALLEY. WILL ALSO HAVE TO MONITOR THE CONVECTIVE
POTENTIAL SUNDAY NIGHT AND MONDAY AS H5 TEMPS DROP TO -32 OFFSHORE OF
SO CAL.
EXPECT SHOWERS TO LINGER WELL INTO MONDAY BEFORE TAPERING OFF MONDAY
NIGHT AND TUESDAY. MOST OF TUESDAY AND WEDNESDAY IS EXPECTED TO BE DRY
AT THIS POINT...BUT TEMPS WILL REMAsIN ON THE COOL SIDE.
