While the remnants of Tropical Storm Kay bring significant rainfall to Southern California, the San Francisco Bay Area is expected to see increased cloud cover and moisture in the air, but little or no rain. Just south of the Bay Area, Monterey County received some scattered sprinkles, but Jeff Lorber, a meteorologist with the National Weather Service, said the showers are dissipating as they move north. “Rain is happening in areas right near our Monterey office and in the Central Valley,” Lorber said. “But it doesn’t go very far north of Monterey. “I received a report of someone working in the East Bay who saw spray on one of the passes near Livermore.” The slight chance of rain in the Bay Area continues into Sunday. KNTV meteorologist Rob Mayeda tweeted that the best chance for rain in the Bay Area on Saturday is in the South Bay. Showers eventually appeared in southern Monterey County, and even a few weak cells west of San Mateo County. But there is no long way for the rain to reach the ground. The chance for showers will continue into Saturday, with the best chances in Monterey and San Benito counties. #CAwx pic.twitter.com/SouHmzhGII — NWS Bay Area 🌉 (@NWSBayArea) September 10, 2022 “There is a non-zero chance of rain in the Bay Area, but the highest confidence remains on the Central Coast,” said Saturday’s forecast from the weather service’s Bay Area office. “Persistent overland flow will lead to quieter weather and a cooling trend for temperatures over the next working week.” September 9, 9 a.m The California heat wave that brought punishing temperatures to the San Francisco Bay Area is finally coming to an end. Friday marks the start of the easing with fog returning and the remnants of Hurricane Kay moving into the area this weekend. Afternoon highs in the Bay Area on Friday will be 5 to 10 degrees cooler than they were Thursday and 15 to 20 degrees cooler than they were at the height of the heat wave Tuesday, the National Weather Service said. Livermore soared to 116 degrees on Tuesday and is forecast to reach 102 on Friday and 88 on Saturday. San Francisco hit 98 on Tuesday and is expected to hit 76 on Friday and 74 on Saturday. “It should definitely feel like a big relief,” said Sarah McCorkle, weather service forecaster in the Monterey office. The colder weather comes as a trough of low pressure to the north and the remnants of Hurricane Kay to the south destroy the ridge of high pressure that brought the sharp rise in temperatures. “We have two low pressure systems pushing us to the north and south and that’s helping to weaken the high pressure,” McCorkle said. Declining high pressure opened the door for coastal fog, and McCorkle said the marine layer that was only a few hundred feet thick in recent days was 1,000 to 1,500 feet off the coast of Monterey this morning. “The marine layer has been deepening, so people in inland valleys and at higher elevations should also feel cooler,” he said. “We’re looking at the fog coming back into San Francisco tomorrow.” A man is covered from the rain with an umbrella in poor condition after heavy rains in Mexico City due to the passage of Typhoon Kay in the State of Baja California, Mexico, which will keep the forecast of rain in several states of the country.

Hurricane Kay Brings Slight Rain Chance to San Francisco Bay Area This Weekend
Tropical Storm Kay made landfall in Mexico on Thursday morning as a hurricane and was downgraded to a tropical storm last night. The storm is expected to move north over the Pacific Ocean, parallel to the California coast, with its eastern edge brushing Southern California on Friday and Saturday, bringing significant rain, up to 2.5 inches in the wettest locations. The remnants of the storm will push into Northern California Saturday through Sunday. Confidence is high that the system could bring showers and thunderstorms to southern portions of Monterey and San Benito counties Saturday night and Sunday morning. “There’s anywhere from a 20 percent to 40 percent chance of rain,” McCorkle said. Parts of Southern California woke up to light rain Thursday morning during the ongoing heat wave in Los Angeles. According to Ryan Kittell, a meteorologist with the National Weather Service in Oxnard, rainfall has been pouring over the Los Angeles Valley and coastal areas, a preview of rain from Hurricane Kay.
