BY TUESDAY NIGHT, THE FRONTAL ZONE WOULD FINALLY MAKE IT INTO THE LOS ANGELES AREAS. THIS MAY HAVE A LOT OF POWER IF ALL GOES RIGHT FOR SOME HEAVY RAINS IN THE AREA WITH THE STRONG 30 KNT SOUTHWEST WINDS IN THE LOWER LEVELS. THE FRONTAL ZONE WOULD SHOW IT'S TRUE SHAPE FINALLY AS IT MOVES JUST PAST THE LOS ANGELES AREA TO THE EAST AS IT INTERACTS WITH THE HIGHER PEAKS OF THE SAN GABRIEL MOUNTAINS. THUNDERSTORMS ARE ALSO POSSIBLE AS THE SAME DYNAMICS FROM TUESDAY EVENING IN VANDENBERG AND SANTA BARBARA MOVE IN. THE WAY TO TELL IF THUNDERSTORMS ARE POSSIBLE WITH THIS FRONTAL PASSAGE ON TUESDAY NIGHT WILL BE TO MONITOR THE VANDENBERG AREAS AS IT PASSES THEM TUESDAY EVENING. THIS WILL TELL THE TALE DOWNRANGE FOR THE LOS ANGELES AREAS, EASTWARD. A 1/4 - 1/2 OF RAIN IS POSSIBLE WITH THE MAIN FRONTAL BURST FOR THE INLAND EMPIRE, AND ORANGE COUNTY / LOS ANGELES BASIN, ON DOWN TO SAN DIEGO COUNTY. THE MOUNTAINS WOULD SEE MORE IN THE RANGE OF 1/2 - 1 OF RAIN.

BY TUESDAY EVENING, THE FRONTAL ZONE WILL BE LOCATED RIGHT ON THE VANDENBERG FORECAST AREA. BETWEEN NOON AND ABOUT 6PM TUESDAY EVENING, THE AREA WOULD HAVE AN ADDITIONAL 1/4 - 1/2 OF RAIN ON TOP OF THE MORNING AMOUNTS. 30 MPH 5,000 FOOT WINDS FROM THE SOUTHWEST WOULD GENERATE OROGRAPHICAL LIFTING ON THE SOUTHERN SLOPES OF THE LOCAL MOUNTAINS. HARDEST HIT AT THIS TIME WOULD BE THE SANTA BARBARA, AND VENTURA COUNTY MOUNTAINS WITH 1/2 - 1 OF RAIN POSSIBLE. SOME COLD AIR ALOFT COMING IN AND SOME PVA DYNAMICS WOULD GENERATE THE CHANCE OF THUNDERSTORMS AS WELL WITH THE FRONTAL ZONE AND SHOULD BE MONITORED CAREFULLY IN CASE ANY WATCHES NEED TO GO UP. WILL LEAVE THIS ONE ALONE AND MENTION THUNDERSTORMS ONLY AT THIS POINT. THE THUNDERSTORMS WOULD MAINLY BE FOR VANDENBERG FORECAST AREA TO KERN COUNTY TO SANTA BARBARA, SPREADING EASTWARD AS THE EVENING WEARS ON.
