New SYNOPSIS, SHORT TERM, LONG TERM
SYNOPSIS
Issued at 1223 AM PST Wed Feb 19 2025
A cold front will move through today. The primary impacts will be some light rain in the North Bay this morning, and gusty winds throughout the cwa into Thursday. Behind the front, a dry and warm pattern will become established, and persist through the forecast period.
SHORT TERM
(Today and tonight)
Issued at 1223 AM PST Wed Feb 19 2025
Prefrontal rain has reached NW Sonoma County, and will continue to push south through the morning. KMUX returns indicate the rain will be mostly light, as advertised. High resolution guidance suggest the rain will continue through the early afternoon, and a few drops may reach as far south as San Jose. The cold front will quickly move through this afternoon, shifting the winds back to NW and allowing the clouds to start clearing. Winds look less concerning than a few days ago, but we are still expecting gusts up to 30 mph along the coast and in the mountains through Thursday night.
LONG TERM
(Thursday through Tuesday)
Issued at 1223 AM PST Wed Feb 19 2025
We're still expecting a warm and dry period from Friday through at least the middle of next week. A quick look at the forecast shows a pretty consistent message during this time, with highs in the mid 60s along the coast to mid 70s inland. When you hear that in February, you might assume offshore winds, but that's not the entire story. Behind the cold front, the air mass will start to dry out and low-level winds will turn northerly, or slightly offshore. You'll notice this by the clear skies Thursday afternoon. But that pattern doesn't last. A low amplitude 500 mb ridge starts building on Thursday and the axis moves through on Friday. This will bring SW flow, allowing a subtropical air mass to nudge its way into the Bay Area. This will usher in higher PWAT values (more water vapor, but no rain). The biggest noticeable difference is that clouds will return over the weekend. Don't get me wrong, there will still be plenty of sunshine, but there will be some clouds mixed in, which could make for some nice sunsets.
This SW flow looks like it will stick around through Tuesday before a cut-off low starts to approach the coast and the forecast gets tricky. These features are notoriously hard to pin- down. To put the uncertainty in perspective, on Wednesday the ECMWF ensemble shows with 80% confidence that 500 mb height will be between 5720m and 5810m, a relatively narrow 90m spread. By Thursday, the spread jumps from 5510m to 5820m, a 310m spread.
There's a chance we get some rain late next week, but it's really hard to say with any certainty. Before we get to that, enjoy the beautiful weather coming up!
AVIATION
(06Z TAFS)
Issued at 900 PM PST Tue Feb 18 2025
VFR prevails with mostly clear skies. VFR will persist through most of the night until Wednesday morning where MVFR conditions start to build between 12-15Z for North Bay and SF Bay terminals. The remaining terminals are expected to see MVFR conditions between 16- 18Z. Scattered showers are expected early Wednesday morning over the North Bay and SF Bay terminals. These conditions should start to improve starting 22-23Z to VFR for most terminals. Winds will remain light overnight but will build to moderate W/NW winds by Wednesday afternoon, then return to light by the evening.
Vicinity of SFO...VFR through the night. Early Wednesday morning MVFR conditions are expected to build but confidence is moderate on timing. Models show agreement that VFR will prevail through the TAF period after 22-23Z. Westerly winds will build to moderate by Wednesday afternoon, before returning to light by the evening.
SFO Bridge Approach...Similar to SFO.
Monterey Bay Terminals...VFR with MVFR conditions building by Wednesday morning (near 16-17Z). Higher confidence that KMRY will see MVFR conditions but some models show VFR through the TAF period for KSNS. A SCT group was included in the TAFs to indicate the possibility for low CIGs near KSNS.
MARINE
(Tonight through next Sunday)
Issued at 314 PM PST Tue Feb 18 2025
Moderate to rough seas continue into the afternoon with moderate northwesterly winds. Expect west- northwest swell building 10-12 feet. There is a chance for scattered light showers over our northern waters tonight through Wednesday morning. Waves and wind will ease for a short time midweek with moderate northwest swell redeveloping late in the week.
