The National Weather Service in San Francisco is forecasting a spell of slight warmth across the Bay Area and Central Coast, ushering in above-normal temperatures and a period of pleasant weather hanging on through the weekend. According to the NWS San Francisco, residents can expect daytime highs to sizzle 10 to 15 degrees above the norm across the interior, climbing into the upper 70s to mid-80s. Coastal regions will also feel a tad warmer, with mercury readings in the upper 60s to mid-70s, nudging slightly above the seasonal average.
While mild offshore flow is calming down, the change to onshore winds, initially slated for Wednesday morning, has been nudged back to Wednesday night into Thursday, according to the NWS's latest advisory. Even with the weakness of the SFO-WMC gradient, which undercut model forecasts, fire concerns aren't heightened, given the high moisture content in regional fuels. Aptly underscoring the light offshore winds, it should take more time than expected for the onshore flow to return.
Transitioning into the weekend, the weather narrative holds a wee bit of cooling as a weak shortwave trough and associated dry cold front glide through the Golden State, dropping temperatures into a more modest alignment. As the trough moves past, the upper-level ridging rebuilds, and temps are projected to warm yet again, setting the stage for a mid- to upper 70s reprise inland and 50s to 60s along the coast.
A shift towards cooler climes begins on Monday, building up to a full-fledged cooling trend with interior highs stepping down to the low to mid 70s. Coastal temps, while still registering in the upper 50s to 60s, will stand noticeably more brisk. Looking ahead, the National Weather Service signals the arrival of unsettled weather next week, which could lead to our next rainfall. Describing an ensemble of model predictions that swing between moderate rainfall and nearly no rain at all, meteorologists are advised by residents to keep their eyes peeled on forecasts as "this system will additionally bring us our next chance for rain," and the picture sharpens in the coming days.
