DISCUSSION
STEADY SOUTHERLY WINDS TODAY BLOWING BETWEEN 15-25MPH MAY
OCCASIONALLY GUST AS HIGH AS 30-35MPH. THE GUSTIEST WIND OF THE
DAY WILL GENERALLY FALL BETWEEN 9AM AND 6PM. A WIND SHIFT WILL
OCCUR BETWEEN 4-6PM AS A DRYLINE PASSES THROUGH THE AREA. WINDS
AROUND THIS TIME WILL QUICKLY SWAP TO A NORTHERLY DIRECTION. IN
ADDITION TO THE WIND FLIP, NOTABLY DRIER AIR WILL INFILTRATE
THROUGH THE REST OF THE AFTERNOON AND EVENING HOURS.
TEMPERATURES STABILIZING IN THE LOWER 90S AROUND 1-5PM WITH
DROPPING DEWPOINTS BEHIND THE FRONT (UPPER 50S TO UPPER 40S) WILL TANK
RH VALUES TO AS LOW AS 20-25% AFTER 2PM. (NEAR-CRITICAL FIRE

THE CHANCE FOR AN AFTERNOON STORM POPPING UP BETWEEN 4-6PM IS NOT
COMPLETELY 0% (~40% CHANCE). THE BEST POTENTIAL LIES EAST OF THE
