Area Forecast Discussion National Weather Service San Francisco CA 126am PST Tuesday Feb 18 2025 ...New SYNOPSIS, SHORT TERM, Long Term Synopsis Issued at 1210am PST Tuesday Feb 18 2025 A cold front will bring light rain to the North Bay Wednesday, and more widespread gusty winds from Wednesday through Thursday. A warming trend will follow, with temperatures climbing 5-10 degrees above normal by the weekend. .SHORT TERM... (Today and tonight) Issued at 1210am PST Tuesday Feb 18 2025 Quiet weather will continue today with increasing clouds, gentle winds and mild temperatures. Temperatures are currently in the mid 40s to low 50s. Mostly clear skies will allow radiational cooling to drop the temperature another 5-10 degrees by dawn. A 500 mb short wave ridge will continue building through the morning, with the axis moving through in the late afternoon. 850 mb temperatures will climb from around 5C to 10C over the next 24 hours due to warm air advection ahead of Wednesday's cold front. This won't translate to much warming at the surface, however as the approaching front will also bring increasing cloud cover through the second half of the day. Afternoon temperatures are only expected to reach the upper 50s to mid 60s, which is pretty typical for this time of year. Long Term (Wednesday through Monday) Issued at 1210am PST Tuesday Feb 18 2025 By Wednesday morning the WPC surface prog shows the cold front just off the coast of northern California, anchored by a 997 mb low pressure system off the coast of central Oregon. Light, prefrontal stratiform rain will likely fall in the North Bay through the early morning, with a few drops possible further south. With only 1/10" or so expected, this rain will not cause any significant impacts. This front will clear out pretty quick, with high pressure quickly building in its wake. The skies will start to clear before the sun sets on Wednesday. There will be some gusty northerly winds both Wednesday and Thursday, but they will likely stay below wind advisory criteria (40 mph gusts) and the recent forecast trend has backed off a bit. Late week the story shifts to a warming trend, especially south of San Franciso. A more persistent ridge builds from Thursday through Monday, allowing a warmer, subtropical airmass to move in. By the weekend, temperatures will be 5-10 degrees above normal. There will be enough moisture and cloud cover to keep overnight temperatures mild. With afternoon temperatures in the mid 60s to mid 70s, no rain, and light wind, it's actually going to be quite nice this weekend. Once they get here, the warm temperatures will last into the first half of next week. Ensemble guidance gets pretty split in the extended range, as a notoriously hard to predict cut-off low may develop in the NE Pacific late next week. Basically, don't put too much trust in any forecast beyond next Wednesday as the uncertainty really starts to balloon. Marine (Tonight through next Saturday) Issued at 354pm PST Monday Feb 17 2025 Moderate northwesterly winds persist. Moderate to rough seas will continue through Tuesday morning, especially along the Big Sur coast. Expect moderate west- northwest swell, building to 10 to 12 feet through today into 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. NOAA San Francisco Bay Area Office: Watches - Warnings - Advisories CA...None. PZ...Small Craft Advisory until 3am PST early this morning for Pt Arena to Pt Reyes 0-10 nm. Small Craft Advisory until 9am PST this morning for Pigeon Pt to Pt Pinos 10-60 NM-Pt Arena to Pt Reyes 10-60 NM-Pt Pinos to Pt Piedras Blancas 0-10 nm.
