TWO SEPARATE LOW PRESSURE SYSTEMS WILL MOVE THROUGH THE AREA NEXT WEEK...BRINGING COOLER WEATHER AND A CHANCE OF SHOWERS AT TIMES. && .SHORT TERM (TONIGHT-MON)...DRY OFFSHORE FLOW WILL KEEP SKIES CLEAR ACROSS THE FORECAST AREA TONIGHT. UPPER LEVEL RIDGING INTO NORTHERN CA COMBINED WITH A STRONG SURFACE HIGH PRESSURE OVER THE GREAT BASIN WILL BRING STRONG AND GUSTY WINDS TO THE FORECAST AREA OVERNIGHT THRU SAT EVENING.

PLEASE SEE THE LATEST NON-PRECIPITATION WEATHER MESSAGE (LAXNPWLOX) FOR DETAILS ON THE HIGH WIND WARNINGS AND WIND ADVISORIES. AN UPPER LEVEL HIGH OFF THE NRN CA COAST WILL BUILD INTO NRN CA LATER SAT NIGHT AND SUN WHILE AN UPPER LEVEL LOW DEVELOPS OFF THE CENTRAL BAJA COAST. THIS WILL RESULT IN A BROAD NE TO E FLOW ALOFT OVER SRN CA THRU THE WEEKEND. THE OFFSHORE FLOW WILL CONTINUE SAT NIGHT INTO SUN WITH MORE WIND ADVISORIES FOR MUCH OF VTU/L.A. COUNTIES. WINDS SHOULD NOT BE AS STRONG SAT NIGHT AND SUN...BUT SOME WIND GUSTS IN THE MTNS COULD STILL APPROACH HIGH WIND WARNING THRESHOLDS AT TIMES. CLEAR SKIES WILL CONTINUE THRU THE WEEKEND... WITH DAYTIME TEMPS WELL ABOVE NORMAL FOR MANY AREAS. HIGHS SHOULD REACH INTO THE LOWER 80S IN THE WARMEST COASTAL AND VLY LOCATIONS. FOR SUN NIGHT AND MON...THE UPPER LOW OFF OF BAJA WILL DRIFT SLOWLY NW WITH A BROAD AND INCREASINGLY MOIST SE FLOW ALOFT OVER SRN CA.

COUNTY. .LONG TERM (TUE-FRI)...THE UPPER LOW WILL MOVE THROUGH SOUTHERN CA ON TUESDAY. IT MUST BE NOTED THAT THERE HAVE BEEN SOME INCONSISTENCIES IN THE COMPUTER PROJECTIONS BETWEEN HOW FAR WEST THE LOW DRIFTS AS EARLY AS MONDAY. THE LAST FEW RUNS HAVE BEEN MOSTLY AGREEABLE AND THE CURRENT ENSEMBLES PUT THE CURRENT SOLUTIONS IN THE WINDOW OF BEST PROBABLE OUTCOME. AS A RESULT...THERE IS MODERATE CONFIDENCE THAT THE CURRENT TRACK WILL COME TO FRUITION...AND BRING MOIST SOUTHERLY FLOW ON THE EAST SIDE OF THIS LOW WITH AMPLE CLOUDS AND MUCH COOLER CONDITIONS. WITH THE AMPLE MOISTURE AND POCKETS OF WARM AIR ADVECTION... EXPECTING SCATTERED SHOWERS MONDAY NIGHT THROUGH TUESDAY. IF THE LOW ENDS UP TRACKING MORE TO THE EAST...WE WONT SEE MUCH IN TERMS OF RAIN AND CLOUDS. REGARDLESS...ANY RAINFALL AMOUNTS WILL LIKELY BE LIGHT AND UNDER A QUARTER OF AN INCH. MIGHT ALSO SEE SOME GUSTY SOUTHEAST WINDS WITH THIS SYSTEM. A WEAK TROUGH WILL FORM BEHIND THE AFOREMENTIONED LOW PRESSURE SYSTEM. THIS TROUGH WILL KEEP CLOUDY AND COOL CONDITIONS GOING THROUGH THE END OF THE WEEK. CURRENT PROJECTIONS CALL FOR NOT MUCH IN TERMS OF MOISTURE...ESPECIALLY AT LOW LEVELS...SO RAIN CHANCES ARE SMALL.
