.DISCUSSION...HIGH PRESSURE PREVAILS OVER THE AREA WEDNESDAY
WITH WARM TEMPERATURES AND DRY WEATHER. A THERMAL TROUGH ALONG
THE COAST WILL LEAD TO EASTERLY WINDS FOR MOST OF THE DAY. HOWEVER
THE TROUGH IS EXPECTED TO MOVE INLAND IN THE AFTERNOON AND PASS
THROUGH THE BURN AREA AROUND 1400. THIS COULD LEAD TO AN ABRUPT
DECREASE IN HUMIDITY AND A QUICK WIND SHIFT TO THE WESTERLY.
EVENING HUMIDITY IS NOT TO IMPROVE SIGNIFICANTLY IN SPITE OF
WESTERLY FLOW. THE RIDGE ALOFT THAT HAS BEEN RESPONSIBLE FOR WARM
AND DRY WEATHER WILL START TO SHIFT EAST OF THE AREA THURSDAY.
THIS WILL LEAD TO SLIGHT COOLING BUT AFTERNOON HUMIDITY ON
THURSDAY IS NOT EXPECTED TO IMPROVE MUCH FROM WEDNESDAY. A MORE
WESTERLY JETSTREAM WILL BRING HIGH CLOUDS INTO THE AREA FRIDAY
WITH RAIN CHANCE INCREASING NEXT WEEKEND.
