A Few Thunderstorms, Then Another Blast Of Heat For The Bay Area

SAN FRANCISCO — Forecasters expect the remnants of Tropical Storm Eugene will bring a slight chance of isolated thunderstorms Thursday and Friday along the Central Coast before the next round of heat settles over Northern California.

The National Weather Service predicts any storms that do develop will stick to southern portions of Monterey and San Benito counties, with activity dwindling after Friday morning. However, the boost in humidity was already evident across much of NorCal by Wednesday morning.

For the Bay Area, the next blast of inland heat is due by Sunday, kicking off a warming trend continuing through early next week.

"Despite the lingering marine layer, temperatures away from the coast will warm into the 80s and 90s with far interior spots shooting for triple-digit heat," NWS Bay Area forecasters wrote Thursday. "Heat risk concerns only reach moderate given [the] time of year and some cooling at night."

Forecasters expect the usual inland hotspots will comfortably reach the 90s by Monday, but even areas closer to the coast should tack on 5-10 degrees of warmth. San Francisco is on track to log several days of sunshine and temps in the 70s starting Sunday.

One quirk in the forecast, courtesy of a "wobbling" low-pressure system, is some potential for showers and storms developing Monday and Tuesday. Forecasters are still monitoring the models to work out the details for any potential moisture.

"Some of the longer range guidance shows the easterly winds aloft advecting upper-level moisture westward over the region," NWS Bay Area said. "Still low confidence at this point, but if the trend continues we may be talking about additional showers and possible storms."
