FROM NORTHWEST TO WEST EARLY THURSDAY AS THE RIDGE BREAKS DOWN UNDER
THE INFLUENCE OF THE NEXT STORM SYSTEM SLIDING DOWN THE WEST COAST

H7 WIND THAT WILL MIX DOWN EARLY THURSDAY AS LAST THROUGH THE DAY
UNTIL DECOUPLING OCCURS SHORTLY AFTER SUNDOWN.  A HIGH WIND WATCH IS
IN EFFECT FOR THIS AREA AS WELL.

THE INFLUENCE OF THE NEXT STORM SYSTEM WILL BEGIN WITH ISENTROPIC
