New AVIATION, MARINE
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!
