THE POSITION OF THE CUTOFF LOW PRESSURE SYSTEM WILL CONTINUE TO BE FAVORABLE FOR IMPORTING MOISTURE FROM THE EAST INTO SOUTHERN CALIFORNIA TODAY. ANY BREAKS IN CLOUD COVER WILL ALLOW DAYTIME HEATING TO INCREASE INSTABILITY... KEEPING THE THREAT OF SHOWERS AND THUNDERSTORMS THROUGH THE DAY. BY THIS AFTERNOON AND EVENING... THE GREATEST THREAT OF SHOWERS AND THUNDERSTORMS WILL BE ACROSS LOS ANGELES AND VENTURA COUNTIES. AS THE CUTOFF LOW CONTINUES TO MOVE SOUTHEASTWARD OVERNIGHT... ADDITIONAL WRAP AROUND MOISTURE WILL KEEP A THREAT OF SHOWERS AND THUNDERSTORMS ACROSS SOUTHERN CALIFORNIA INTO WEDNESDAY MORNING. SOME OF THE THUNDERSTORMS TODAY COULD BE STRONG... CAPABLE OF PRODUCING BRIEF HEAVY RAIN... GUSTY WINDS... SMALL HAIL... AND FREQUENT LIGHTNING.
