| Area Forecast Discussion National Weather Service San Francisco CA 1056am PDT Wednesday May 8 2024 Issued at 922am PDT Wednesday May 8 2024 Temperatures across the greater SF Bay Area are running around 10 to 15 degrees warmer than this time yesterday, with more mixed signals across the Central Coast. Meanwhile, gusty winds continue in the North Bay interior mountains. Peak gust reports include a 72 mph gust at the Santa Fe Geothermal PGE station, a 61 mph gust at Mount Saint Helena, a 50 mph gust on Blue Ridge Road South, and a 61 mph gust on Mount Diablo. No changes to the forecast. DialH .SHORT TERM... (Today and tonight) Issued at 300am PDT Wednesday May 8 2024 Clear sky conditions continue across the region this morning and offshore winds have developed aloft. This will result in a warming trend today with temperatures reaching the low-to-mid 80's across the interior while 60's will be common near the coast (70's in places such as Santa Cruz). A Wind Advisory remains in effect for the North Bay Interior Mountains with gusts expected to reach 45 mph and may exceed 55 mph in the Mayacamas Mountains through Thursday morning. Gusts in the East Bay Hills are not expected to be widespread enough to warrant an advisory, but Mount Diablo is expected to see similarly strong, gusty winds. Overnight lows will be warmest in the North Bay and interior part of the East Bay given the offshore flow with temperatures only expected to cool into the mid-to-upper 50's (lower 60's in the highest peaks). Elsewhere, upper 40's to mid 50's are expected overnight. Long Term (Thursday through Tuesday) Issued at 300am PDT Wednesday May 8 2024 The warming trend continues into the early part of the upcoming weekend, with Thursday and Friday expected to be the warmest days of the week. High temperatures will range from the upper 60's to lower 70's near the coast (lower 80's in places such as Santa Cruz and downtown San Francisco), to the upper 80's to lower 90's inland, especially by Friday. From previous forecaster: "The seasonably warm temperatures are causing a minor to moderate HeatRisk, meaning that a low to moderate risk for heat related illnesses exists for vulnerable populations (children, the elderly, pregnant women, or those without adequate shelter or cooling), with moderate HeatRisk values concentrated in the interior regions of the North, East, and South Bays. With the significant warm up expected for the rest of the week, here's a reminder of some heat safety tips: * Stay hydrated and drink plenty of fluids. * Wear lightweight, light-colored clothing. * Reduce time spent outdoors or stay in the shade. * Never leave people or pets unattended in vehicles. * Use sunscreen if going to the coast or the pool. The heat should start to abate on Sunday as onshore flow returns to the region, but temperatures warmer than the seasonal averages are expected to continue for the foreseeable future, with CPC products stating that temperatures above seasonal averages continue into the third week of May." Marine (Today through Monday) Issued at 908am PDT Wednesday May 8 2024 High pressure to the north and low pressure to the south will maintain moderate to locally strong northerly winds over the coastal waters and bays through tonight. The stronger northerly winds will result if fresh steep swell today. By Friday, winds are largely light to moderate across much of the waters. Wave heigheights gradually diminish to around 5 to 7 feet by late week. Dry weather continues through the forecast period as high pressure dominates.
