LIKELY DURING THE DAY. SUNNY...COOL AND BREEZY WEDNESDAY AND
THANKSGIVING. A LITTLE WARMER FRIDAY...BUT THEN INCREASING CLOUDS
WITH A SLIGHT CHANCE OF RAIN FOR THE WEEKEND.
&&
.SHORT TERM (TODAY-WED)...
CLEAR AND COLD OVER THE AREA FOR SINCE LAST EVENING. THE CLEAR SKIES
AND LIGHT WINDS HAVE ALLOWED TEMPS TO DROP INTO THE 30S AND WITH
STILL A FEW MORE HOURS OF NIGHT TIME LEFT THERE WILL LIKELY BE
FREEZING TEMPS IN THE INTERIOR. A FROST ADVISORY COVERS THE NON
MOUNTAIN INTERIOR SECTIONS OF THE FORECAST AREA. THERE
IS...HOWEVER...A LITTLE IMPULSE ROTATING INTO THE CENTRAL COAST AND
THIS IS BRINGING SOME CLOUDS AND A SLIGHT CHC OF SHOWERS WITH IT.
THESE CLOUDS MAY WELL DISRUPT THE COOLING NORTH OF POINT CONCEPTION
AND PREVENT AREAS OF FROST ALTHOUGH MANY INLAND TEMPS ARE ALREADY AT
OR NEAR FREEZING. THE SHOWERS WILL NOT PRODUCE MUCH IN THE WAY OF
PRECIPITATION. THE ONLY OTHER AREA WITH A CHANCE OF SHOWERS ARE THE
NORTH SLOPES OF THE MOUNTAINS WHERE CLOUDS AND SOME SHOWERS HAVE
FORMED IN THE UPSLOPE FLOW. SNOW LEVELS WILL BE QUITE LOW AROUND
4500 FEET RISING SLIGHTLY TO 5000 FEET DURING THE DAY. AT THE
BEACHES THE NEARLY FULL MOON IS CAUSING A HIGHER THAN NORMAL TIDE
AND THIS IS COMBINING WITH SOME WIND WAVES TO PRODUCE A LITTLE BEACH
FLOODING LATER THIS MORNING.
A LITTLE FRONT WILL MOVE THROUGH THE AREA TUESDAY. IT WILL LIKELY
BRING RAIN TO THE ENTIRE AREA. IT IS NOT A STRONG OR PARTICULARLY
WET FRONT AND IT WILL LIKELY NOT PRODUCE MORE THAN A QUARTER INCH OF
RAIN IN ANY ONE LOCATION AND MANY AREAS WILL SEE QUITE BIT LESS.
RAIN WILL DEVELOP BY LATE MORNING NORTH OF POINT CONCEPTION AND THEN
MOVE THROUGH VTA AND LA COUNTY DURING THE AFTERNOON. THE SHOWERS
WILL THEN END AND THE CLOUDS WILL DECREASE TUESDAY EVENING.
WINDS WILL THEN BECOME THE WEATHER FOCUS. NORTH WINDS WILL DEVELOP
EARLY WEDNESDAY MORNING...STRONGEST THROUGH THE I-5 CORRIDOR...THE
SANTA YNEZ RANGE AND THE SANTA BARABARA SOUTH COAST...WITH DECENT
WINDS EXPECTED THROUGH THE SANTA MONICAS AND SANTA CLARITA VLY. SOME
WIND ADVISORIES WILL LIKELY BE NEEDED FOR THESE WINDS. COLD AIR
ADVECTION WILL CONTINUE THROUGH THE DAY AND MOST COASTAL AND VLY
AREAS WILL SEE MAX TEMPS ONLY IN THE THE LOWER 60S WITH SOME VLY
LOCATIONS ONLY SEEING UPPER 50S DESPITE SUNNY SKIES.
