GENERALLY CLEAR SKIES ARE EXPECTED THROUGH FRIDAY...THEN A WEAK FRONT MAY BRING LIGHT RAIN TO AREAS NORTH OF POINT CONCEPTION ON FRIDAY NIGHT...BEFORE SPREADING SOUTH OVER THE WEEKEND OR EARLY NEXT WEEK. && .SHORT TERM (TODAY-FRI)... CLEAR SKIES OVERHEAD THIS MORNING SAVE FOR SOME CLOUDS ACROSS THE NORTH SLOPES AND REACHING INTO THE NORTHERN PORTION OF THE TEJON PASS. STILL BREEZY BUT WINDS ARE DYING OFF. WIND WARNINGS WERE DOWN GRADED TO ADVISORIES FOR LA/VTA MTNS AND CANCELLED OVER THE SBA MTNS. WEAK ADVISORIES CONTINUE FOR THE LA/VTA VLYS THROUGH EARLY AFTERNOON. BIGGEST STORY IS ACTUALLY THE COLD. 538 DM HGTS OVER L.A. RIGHT NOW OR A LITTLE OVER 20 DM LOWER THAN NORMAL. TRICKY OVERNIGHT LOWS DUE TO THE WINDS. WINDY AREAS WILL BE MUCH WARMER THAN WIND SHELTERED AREAS. HARD FREEZE THIS MORNING FOR CUYAMA AND PLENTY OF NEAR FREEZING TEMPS EVERYWHERE ELSE ACROSS THE CENTRAL COAST. OTHERWISE TODAY WILL BE SUNNY BREEZY AND COOL WITH MAX TEMPS RUNNING 3 TO 5 DEGREES BLO NORMAL. HIGH PRESSURE OVER NEVADA WILL CREATE LOCAL NORTHEAST WINDS TONIGHT BUT NOTHING TOO STRONG OR WIDESPREAD. CLEAR SKIES AND CALM WINDS WILL ALLOW AN ALREADY COOL ATMOSPHERE TO RADIATE AND COOL FURTHER. THE INTERIOR PORTIONS OF THE FORECAST AREA WILL SEE MIN TEMPS IN THE 20S WHILE THE ANTELOPE VLY WILL SEE LOWS DIP INTO THE TEENS. MEANWHILE MOST OF THE VLYS AND THE INTERIOR PORTIONS OF THE COAST WILL SEE MIN TEMPS NEAR FREEZING. IT WILL BE SUNNY AGAIN ON THURSDAY AND WITH WEAK OFFSHORE FLOW MAX TEMPS WILL RISE TO NEAR NORMAL. ALL MDLS ARE NOW SLOWING DOWN THE ARRIVAL OF THE NEXT WEAK FRONT. AS A RESULT FRIDAY IS GOING TO BE PRETTY DECENT DAY. THE CENTRAL COAST WILL SEE A SLIGHT INCREASE IN CLOUDS AND SOUTH OF POINT CONCEPTION SKIES WILL REMAIN MOSTLY SUNNY. HGTS FALL A LITTLE AS PARENT TROF OF THE FRONT NEARS AND THIS WILL KNOCK A DEGREE OR TWO OFF OF THE MAX TEMPS. .LONG TERM (SAT-TUE)... MDLS NOW AGREE THAT THE FRONT WILL APPROACH THE CENTRAL COAST LATE FRIDAY AND EARLY SATURDAY AND THEN MOVE THROUGH THE AREA SATURDAY REACHING L.A. IN THE EARLY EVENING. LOOKS LIKE ANOTHER HIGH POP LOW QPF EVENT WITH QUARTER TO HALF INCH AMOUNTS. THIS SYSTEM WILL NOT BE NEARLY AS COLD AS YESTERDAYS. IT LOOKS LIKE SUNDAY WILL BE A COOLER DAY WITH SOME LEFT OVER SHOWERS BUT NOTHING TOO SIGNIFICANT. BOTH EC AND GFS AGREE THAT ANOTHER FRONT WILL MOVE INTO THE AREA ON MONDAY. THE 06Z GFS IS A LITTLE MORE BULLISH WITH THE RAIN THAN THE 00Z RUN. BUT STILL THE OFF HOUR RUNS OF THE GFS ARE ALWAYS A LITTLE KOOKY SO WILL WAIT A RUN OR TWO TO SEE IF THIS FCST TAKES HOLD. ALL MDLS KEEP XMAS DAY DRY NEAR NORMAL TEMPS. && .AVIATION... 19/1130Z... OVERALL...HIGH CONFIDENCE IN 12Z TAF.
