Bay Area Braces for Cool Temperatures, Rain, and Thunderstorms Cool temperatures and steady rain are expected to blanket the Bay Area and Central Coast throughout Monday, with wet conditions persisting through Wednesday. Isolated to scattered thunderstorms may develop on Tuesday, according to the National Weather Service. The advisory issued early Monday morning highlights the widespread rain forecast across the North Bay, San Francisco, the Peninsula, East Bay, South Bay, Santa Cruz County, and Monterey counties, with warnings of slick roads, ponding on streets, and potential for minor urban and nuisance flooding in some areas. Rainfall totals through Wednesday are projected to range from 1 to 2 inches in valley locations and 1.5 to 3 inches in mountainous regions of the region. Thunderstorms are most likely to occur on Tuesday, with forecasters indicating a 20% to 35% chance of thunderstorms across much of the Bay Area and Central Coast. These storms could bring lightning, brief heavy rain, gusty winds, and small hail. A slight chance of lingering thunderstorms may extend into Wednesday, though confidence in their occurrence is lower. Temperatures are expected to remain cool through midweek, with the National Weather Service noting that seasonal conditions and drier weather are anticipated to return later in the week. The prolonged wet weather could lead to challenges for commuters and residents, particularly with the risk of flooded streets and reduced visibility. Forecasters emphasize the need for caution, especially during the early morning hours when the advisory was issued, as the combination of rain and cooler temperatures may create hazardous driving conditions.#national_weather_service #bay_area #central_coast #mountainous_regions #north_bay
