Area Forecast Discussion National Weather Service San Francisco CA 120pm PST Monday Feb 17 2025 ...New SHORT TERM, Long Term Synopsis Issued at 1202am PST Monday Feb 17 2025 Relatively benign weather through Tuesday before another cold front moves through on Wednesday. This system will bring light rain to the North Bay, and strong winds to the coast and higher elevations. A warming trend will begin late week before a beautiful weekend. .SHORT TERM... (This evening through Tuesday) Issued at 119pm PST Monday Feb 17 2025 Developing upper level ridging will keep our short term weather fairly benign. Scattered clouds continue to drift across the Bay Area with noon observations showing temperatures in the mid to upper 50s. We'll see some slight warming continue through the rest of the day with highs generally peaking in the upper 50s to low 60s. Tonight into tomorrow morning, temperatures will cool in the upper 30s to low 40s with patchy dense fog possible across the valleys. Portions of the far southern Salinas Valley (nearby the community of Bradley) may be locally colder in the low to mid 30s overnight. All in all, a pleasant February day across the region. Long Term (Tuesday night through next Sunday) Issued at 119pm PST Monday Feb 17 2025 The pattern becomes a bit more interesting for the upcoming week. Tuesday will be fairly similar to Monday with temperatures a few (up to 5) degrees warmer than on Monday as upper level ridging continues. Wednesday will see an upper level trough moving into the West Coast with an associated weak surface low moving into Oregon/Washington. A cold front associated with this system will extend southward and pass through the Bay Area and Central Coast Wednesday evening into Thursday. The bulk of the rainfall from this system will be well to our north but the North Bay, San Francisco, and coastal portions of the San Mateo Peninsula will see some light rainfall. Most areas will see only a few hundredths of an inch while northern most portions of Sonoma County may see between a tenth to two tenths of an inch. Winds will be stronger Wednesday and Thursday with gusts generally peaking between 20 to 30 mph and up to 40 mph on the highest peaks. Current guidance keeps the region below Wind Advisory criteria but we'll continue to keep an eye on winds, particularly across the North Bay, and update if this changes. On Thursday, upper level troughing will move eastward into the Four Corners region as upper level ridging once again builds over the West Coast. This kicks off a warming trend with most inland rising into the upper 60s Thursday and Friday. Further warmer will occur over the weekend with more sites across the South Bay, East Bay, and interior Central Coast rising into the low to mid 70s. This is above normal by about 5 to 10 degrees for the Bay Area and Central Coast at this time of year. Dry conditions are expected to continue from the end of this week through the end of February with the CPC highlighting below normal precipitation and above normal temperatures. The weeks 3-4 CPC outlook does show above normal precipitation for the North Bay so we will have to see how things evolve as we head into early March. Marine (Today through Saturday) Issued at 928am PST Monday Feb 17 2025 Moderate to rough seas will persist through Tuesday morning, especially along the Big Sur coast. Expect moderate west- northwest swell, building to 10 to 12 feet for today and Tuesday. Wind and waves ease for a short time before building back to moderate northwest swell for the second half of the work week. Beaches Issued at 243am PST Monday Feb 17 2025 Moderate west swell 10 to 11 feet at 15 seconds will arrive along our coast beginning early this morning, swell periods are forecast to decrease to 14 seconds early Tuesday morning. This will bring breaking waves generally between 10 to 15 feet with occasional breaking waves up to 18 feet possible. At this time a beach hazards statement is not warranted, however surf conditions will be closely monitored through early week. As always, if going to the beach especially during increased surf, it's important to be vigilant and never turn your back on the ocean.
