DISCUSSION
HIGH HUMIDITY RECOVERIES AND LIGHT WINDS COULD BRING AREAS OF DENSE FOG TO THE
FIRE AREA THIS MORNING. OTHERWISE LOOK FOR A MOSTLY SUNNY TO PARTLY CLOUDY DAY
TODAY, WITH A LIGHT SOUTHERLY WIND DEVELOPING. HIGHS NEAR 70 DEGREES WILL BRING
AFTERNOON HUMIDITY VALUES IN THE MID 40S. AN OVERALL DRY FORECAST IS EXPECTED TODAY,
WITH UP TO A 10 PERCENT CHANCE OF AN ISOLATED SHOWER THIS AFTERNOON. TONIGHT, A
STEADY SOUTHERLY WIND WILL REMAIN WITH MAINLY DRY CONDITIONS EXPECTED. HUMIDITY
RECOVERIES COULD AGAIN BE HIGH AND NEAR 90 PERCENT.
SATURDAY, BREEZY SOUTHERLY WINDS WILL BE FOUND TO START THE DAY. A COLD FRONT WILL
THEN BRING BREEZY WEST NORTHWEST WINDS IN THE AFTERNOON. THIS COLD FRONT COULD ALSO
BRING SOME SHOWERS AND THUNDERSTORMS SATURDAY AFTERNOON INTO THE EARLY EVENING. AN
ISOLATED STRONG TO SEVERE STORM IS POSSIBLE, WITH GUSTY WINDS AND LARGE HAIL BEING
THE MAIN THREAT. AHEAD OF THIS FRONT WILL BE SLIGHTLY WARMER HIGH TEMPERATURES,
LOWERING HUMIDITY VALUES TO NEAR 40 PERCENT.
