Area Forecast Discussion National Weather Service San Francisco CA 124am PDT Thu Mar 27 2025 ...New SYNOPSIS, SHORT TERM, Long Term Synopsis Issued at 1201am PDT Thu Mar 27 2025 Disturbed weather continues with periods of overcast skies, cloud cover, cool temperatures, light rain and moderate wind. There will be a brief dry period Friday - Saturday before rain returns Sunday and intensifies mid-week. .SHORT TERM... (Today and tonight) Issued at 1201am PDT Thu Mar 27 2025 An impressive surface low is located northwest of California just offshore of the border of Northern California and Oregon. A trailing cold front associated with this low is pushing southwards into the Bay Area and Central Coast. This system has helped push upper level ridging eastward away from the West Coast and helped bring our high temperatures down closer to seasonal averages (if not a few degrees below average). High temperatures across the interior will be in the low to mid 60s while highs along the coastline will be in the upper 50s to low 60s today. Comparatively, low temperatures this morning are running about 5 to 10 degrees above normal in the mid 40s to mid 50s. A look at satellite data shows widespread overcast skies which act to trap heat/reduce radiational cooling at the surface and results in warmer morning low temperatures than normal. KMUX is showing light rain entering the Bay Area and Central Coast with a few sites in Santa Cruz and San Mateo Counties reporting a few hundredths of an inch. Totals are locally higher across the North Bay where drizzly conditions persisted much of yesterday. Light rain continues through the rest of the day into Friday for the North Bay and coastal Bay Area counties. Totals from this event won't be too impressive, with most sites south of the Golden Gate seeing up to a quarter of an inch and up to half an inch across the North Bay. On a slightly more impactful level, gusty winds are expected again today across the region with widespread gusts between 20 to 30 mph and gusts up to 35 mph along elevated terrain. The KSFO-KWMC (Winnemucca, NV) forecast pressure gradient shows the forecast gradient strengthening to +15 mb to +16 mb Thursday afternoon which is reflective of strong onshore winds across the Bay Area. This is supported by probabilistic NBM guidance which places the highest confidence in widespread gusts between 20 to 30 mph. Peaks and ridgelines have a low (generally <30-40%) chance, outside of Mt. St. Helena, for gusts greater than 35 mph. Winds should start to ease by late Thursday evening with guidance showing the KSFO-KWMC pressure gradient starting to ease by late Thursday evening. All in all, impacts from rain will be minimal but locally gusty conditions may require any loose outdoors items be secured or brought inside for the day. Long Term (Friday through Wednesday) Issued at 1201am PDT Thu Mar 27 2025 A weak short wave will move through Friday morning, followed quickly by building high pressure from the NE Pacific. This will bring a reprieve from the rain from mid day Friday-Saturday. By Sunday, an approaching warm front associated with a cut-off low pressure system west of the PNW will bring another round of light to moderate rain throughout the day and into Monday morning as the cold front moves through. The overall accumulation is expected to be around 0.5-1" in the North Bay, with somewhere between 0.1" and 0.5" elsewhere throughout the Bay Area and Central Coast. In other words, this looks to be another beneficial event. As the parent low pressure system moves inland, the resulting upper level troughing will push the jet stream further south. By Tuesday, the jet stream will be aimed somewhere over the Bay Area or Central Coast. This will bring some wind to the surface, and could bring more substantial rain, but that depends on the available moisture. The combined 80-member GEFS and ECMWF (European Centre for Medium-Range Weather Forecasts) EPS multi-model ensemble mean brings about 36 hours of greater than 250 IVT. According to the CW3E definition, that would classify as a weak AR. Adding 1 standard deviation to the mean brings a long duration moderate AR, while subtracting 1 standard deviation wouldn't even classify as an AR. So there is still some uncertainty with the exact amount of precipitation we'll get next week. One thing is becoming clear, we will get several days of rain, and it should add up to be quite a bit more than we've seen this week. Most areas outside of the standard rain shadows should expect to receive at least an inch of rain throughout the week. Marine (Tonight through next Tuesday) Issued at 1100pm PDT Wednesday Mar 26 2025 Winds will stay moderate to breezy through the night before turning southwest and strengthening to a strong breeze across the waters Thursday. Seas will also deteriorate with widespread rough seas beginning early Thursday morning. Rough seas continue into the weekend with unsettled conditions to persist into next week as a series of storm systems move through the region. Beaches Issued at 1119am PDT Wednesday Mar 26 2025 Thursday morning, a new incoming swell will generate large breaking waves up to 30 feet, in addition to enhanced rip currents. Inexperienced swimmers should stay out of the water. Beachgoers should maintain a further stand-off distance from the water than normal. Stay off of jetties and rocks, keep pets on a leash, wear a life jacket, and never turn your back on the ocean!
