SANTA BARBARA, Calif. - The heat wave is here and likely peaked on Wednesday for several coastal cities, with downslope Santa Lucia winds significantly drying out and warming up areas like San Luis Obispo, Pismo Beach and Morro Bay to the triple digit mark or well above it, shattering typical highs for this time of year. Tonight as winds diminish, the beaches will cool to the 50s and 60s overnight with valleys staying warm into the early morning.
On Thursday it appears Central Coast beach cities will get some relief, with temperatures still on the warm side topping out in the 70s and 80s. Inland areas will be sweltering, however, breaking triple digits once again. Increasing scattered clouds are possible, but high pressure's tight grip over the region will keep everyone mostly sunny and warm to hot.
On Friday the heat sticks around, though we begin to see more cooling as the flow turns more onshore. We'll begin to see more coastal fog and significantly cooler temperatures late this weekend and into early next week, coinciding with Father's Day and the official start of summer on Sunday.
