GUSTY SOUTHWEST WINDS ESCORTED AN UNSEASONABLY WARM AIRMASS ACROSS  
THE REGION THIS AFTERNOON. HIGHS REACHED INTO THE MID AND UPPER 80S,

ON SATURDAY, UNSEASONABLE WARMTH WILL CONTINUE WITH HIGHS TOPPING  
OUT IN THE MID 80S TO 90 DEGREES. BUT IT WILL BE COOLER ONCE AGAIN  
ALONG THE SOUTH COAST DUE TO ONSHORE WINDS, WHERE HIGHS WILL ONLY
