| Area Forecast Discussion National Weather Service San Francisco CA 330am PST Tuesday Nov 3 2026 .SHORT TERM... Issued at 1251pm PST Monday Nov 2 2026 (Today and Tonight ) Rain returns to the Bay Area and some of the Central Coast. A low pressure currently off the NorCal coast will bring rain back to the region early Tuesday morning and lingering into Tuesday night. Rain is currently being detect over the coastal waters and is expected to enter the N Bay close to sunrise and the Bay Area after sunrise impacting theam commute. The best forcing and moisture will be over the N Bay with chance for moderate rain. The farther south you go rain becomes more light with interior Central Coast receiving no rain. Rain totals remain the same: highest across the coastal N Bay Mts 0.5-0.75". The rest of the North Bay and the Santa Cruz Mountains will see 0.25-0.5" while the remainder of the Bay Area sees less than a tenth of an inch. The real wildcard in all of this today will be the chance for thunderstorms. As the low pressure moves into the N Bay coastal waters this afternoon it will usher in some cold air aloft. This will help to destabilize the atmosphere - higher CAPE/ML CAPE and favorable lapse rates for thunderstorm development. Shear parameters on the latest guidance are still on track to promote the potential for rotating cells/waterspouts. The obvious concern would be any waterspouts moving inland. Thankfully, once the low moves inland the overall convective environment fades pretty quick. Showers will last into the first part of tonight for most of the CWA (County Warning Area) with the exception of the interior Central Coast. Long Term Issued at 1159pm PST Monday Nov 2 2026 (Wednesday through next Monday) Chamber of commerce type of weather returns for the long term forecast. High pressure build in behind the departing rain-maker from Tuesday. A warming and drying trend kicks off on Wednesday and counties well into the weekend. Temperatures will initially be seasonably cool on Wednesday with highs in the 60s to lower 70s, but by Saturday highs soar into the 70s and lower 80s or 10-15 degrees above normal. Relatively clear skies will lead to cool overnight lows during the long term, but nothing too cold. Taking a peek beyond the long term period looks interesting. A lot can happen between now and then, but early indications show the storm door may open and remain open well into the middle of November. CPC keep the 6-10 and 8-14 day above normal temps and above normal rain. Atmospheric River guidance also shows a much more active EPac with the potential for ARs to impact the region. Be sure to follow for future updates. Based on the latest tidal information and predicted surge another round of Coastal Flood Advisories may be need Wednesday through Monday.
