| Area Forecast Discussion National Weather Service San Francisco CA 525pm PDT Sat September 14 2024 .SHORT TERM... (This evening through Sunday) Issued at 1257pm PDT Sat September 14 2024 Stratus persists at the immediate coastal regions, with some mixing out possible through the afternoon although patches of stratus look to persist through the day. A deep marine layer of around 1500-2000 feet deep will promote extensive inland stratus development tonight into Sunday morning. The weather pattern is dominated by a upper level trough developing off the Pacific Northwest, which is expected to develop into an upper level low that comes through the state on Sunday and Monday. Breezy onshore winds pick up this afternoon, remaining rather strong overnight into Sunday with the arrival of a cold front. The strongest winds are expected Sunday afternoon, with gusts reaching 25-30 mph across the lower elevations, and 35-45 mph in the higher elevations, through gaps, passes, and the Salinas Valley. Take some time today to bring in anything that could easily blow away or over, unless, as the previous forecaster noted, you want to recreate a scene from Mary Poppins! Also arriving later on Sunday are chances for rain. While the chances start arriving late on Sunday, it's now looking more likely that the bulk of the rainfall will arrive on Monday, see the long term discussion for more information about the rainfall. Highs today range from the lower 80s to the lower 90s across the inland valleys, to the 70s across the Bayshore, and the low to mid 60s along the Pacific coast. With the cold front on Sunday, expect a dramatic fall in temperatures with the inland valleys cooling to the 70s, the Bayshore seeing highs in the mid to upper 60s, and even the warm spots in southern Monterey County topping out in the low 80s. Long Term (Sunday night through next Friday) Issued at 1257pm PDT Sat September 14 2024 It's now looking more likely that the bulk of the rain from the approaching low will fall Monday morning and afternoon. Even then, not much rain is expected. The latest forecast shows the higher elevations (the Santa Cruz Mountains, the eastern Santa Clara County mountains, and the northern Gabilan and Santa Lucia ranges) reaching around a tenth to a quarter of an inch of rain, with some of the favored peaks seeing up to a third of an inch. Most of the lower elevations in the Bay Area and Central Coast will see a few hundredths to a tenth of an inch of rain, and in the North Bay valleys and southern Monterey County, you'd be lucky to see any rain at all. Of note, the latest extended HRRR (High-Resolution Rapid Refresh) model run shows that the rain may be more showery than stratiform; if this model situation plays out, rainfall totals could be a lot more uncertain as predicting where a shower will develop is very difficult. Something to watch over the next few days. The rain should come to an end Monday afternoon, with most of the region seeing highs in the upper 50s to the 60s, and the inland valleys struggling to reach the low 70s, barring the North Bay where temperatures could reach the mid 70s. Tuesday should bring a slight warming trend with the inland valleys returning to the mid to upper 70s, before a second low pressure system arrives on Wednesday. Similar to Monday's system, there's not a lot of rain expected with this one with rain totals a few hundredths of an inch at most. The chances for rain end on Thursday, with ensemble models suggesting a return to upper level ridging towards the following weekend. CPC outlooks lean towards the return of temperatures slightly above seasonal averages towards the last full week of September. Marine (Tonight through next Thursday) Issued at 453pm PDT Sat September 14 2024 A series of early season cold fronts will move through the coastal waters this week with a persistent strong NW breeze and near gale force gusts. Seas will remain rough outside of protected waters through the forecast period. There a chance for thunderstorms Monday and Wednesday, which would produce locally stronger winds.
