A warming trend is expected to continue across the Bay Area through late this week, according to the National Weather Service. As pressure builds over California from the east, a heat wave will bring high temperatures to the hottest places in the Bay Area until Friday, according to the NWS.
Temperatures are expected to peak on Wednesday with highs in the 90s and low 100s in certain places.
Onshore flow and a shallow marine layer will keep temperatures in coastal areas in the upper 60s to mid 70s, NWS officials said. Cooling is forecast to begin on Friday as low atmospheric pressure approaches the Pacific Northwest.
