Fire Weather, Offshore Wind Event

HIGH PRESSURE ALOFT...CURRENTLY TO THE SOUTHWEST...WILL GRADUALLY BUILD EASTWARD THROUGH THE WEEK...SETTLING OVER SOUTHERN CALIFORNIA ON WEDNESDAY AND THURSDAY. AT THE SAME TIME...SURFACE HIGH PRESSURE WILL BUILD INTO THE GREAT BASIN. THIS COMBINATION WILL PRODUCE AN OFFSHORE FLOW PATTERN ACROSS THE AREA THIS WEEK. TONIGHT THROUGH TUESDAY NIGHT...THE LOW-LEVEL FLOW WILL BE NORTHERLY. THIS WILL PRODUCE SOME GUSTY NORTH WINDS IN THE USUAL AREAS...INCLUDING THE SANTA YNEZ RANGE AND THE INTERSTATE 5 CORRIDOR. NORTHERLY WIND GUSTS BETWEEN 35 AND 45 MPH WILL BE POSSIBLE IN THE WINDIER SPOTS. BY WEDNESDAY MORNING AND CONTINUING THROUGH THURSDAY THE WINDS WILL SHIFT TO THE NORTHEAST WITH GUSTS TO BETWEEN 35 AND 40 MPH LIKELY IN THE WINDIER SPOTS. ON WEDNESDAY AND THURSDAY...AS THE WINDS SHIFT TO THE NORTHEAST... AFTERNOON TEMPERATURES WILL JUMP DRAMATICALLY. TEMPERATURES IN THE 90S ARE LIKELY ACROSS THE VALLEYS AND EVEN THE COASTAL PLAIN. AS THE TEMPERATURES INCREASE...RELATIVE HUMIDITY WILL TUMBLE. INLAND AREAS WILL EXPERIENCE AFTERNOON RELATIVE HUMIDITY IN THE TEENS ON WEDNESDAY THEN INTO THE LOW TEENS AND SINGLE DIGITS ON THURSDAY. OVERNIGHT RECOVERY WILL BE POOR AWAY FROM THE COAST. THE COMBINATION OF THE OFFSHORE WINDS...HOT TEMPERATURES AND LOW RELATIVE HUMIDITY MAY PRODUCE A FEW HOURS OF CRITICAL FIRE WEATHER CONDITIONS ON WEDNESDAY AND THURSDAY. THE RAINFALL FROM LAST WEEK WILL MITIGATE THE SITUATION SOMEWHAT...BUT THERE WILL BE A HEIGHTENED FIRE WEATHER CONCERN WEDNESDAY AND THURSDAY.
