&&

.DISCUSSION...COLD TEMPERATURES AND CONTINUED HEADLINES WILL ONCE
AGAIN BE THIS MORNING FORECAST CHALLENGE. THE HARD FREEZE WARNING
IS VERIFYING NICELY EARLY THIS MORNING WITH TEMPS RANGING FROM
27-30 DEGREES ALONG THE NORTH COAST. DESPITE WARMING ALOFT...WED
MORNING MAY BE JUST AS COLD AS IDEAL RADIATIONAL COOLING CONDS PERSIST.
LIKE LAST NIGHT...WE WILL NOT COMPLICATE MATTERS BY ISSUING
HEADLINES BEYOND THIS MORNING AND LET THE DAY SHIFT MAKE THE FINAL
DETERMINATION.

A WEAK SHORTWAVE WILL DROP SOUTH TODAY ON NORTHWEST FLOW ALOFT
SPREADING A FEW CLOUDS ACROSS THE REGION. RIDGING THEN TAKES OVER
BEGINNING TONIGHT WITH CLEARING SKIES AND SLOWLY MODERATING
TEMPS. THE SHORT LIVED RIDGE MOVES OFF TO THE EAST ON THU AS A
WEAK UPPER LOW APPROACHES THE COAST. THIS LOW IS THE FIRST IN A
SERIES AS WESTERLY FLOW STRENGTHENS ACROSS THE PACIFIC. THIS FIRST
LOW ON THU IS EXPECTED TO DIVE SOUTH INTO CENTRAL/SRN CA AS THE FLOW
ALOFT OVER THE STATE IS STILL SPLIT. THE GLOBAL MODELS HAVE
FINALLY COME INTO BETTER AGREEMENT SHOWING A WET AND WARMER
PATTERN BEGINNING THIS WEEKEND. THIS PATTERN HAVE BEEN SLOW TO
EVOLVE...BUT ONCE IT DOES...THE WESTERLY JET LOOKS TO REMAIN
FOCUSED ON CA FOR A PROLONGED STORMY PERIOD. JCA

TO HAVE A DECENT HANDLE...BUT MAINTAINS SEAS TOO HIGH FOR TOO LONG.
NOT MUCH WINDS IN THE FORECAST TIL THU OR FRI WHEN A EAST PAC STORM
APPROACHES 130W AND WE SEE ROBUST SOUTHERLY WINDS. A SOLID SCA
EVENT...WITH MARGINAL LOW END GALE CHANCES INTO SAT. DJB
