New AVIATION, MARINE
SYNOPSIS
Issued at 200 PM PDT Thu Apr 25 2024
Cool temperatures will continue today. A cold front will bring a chance for light rain beginning tonight, with strong winds Friday night. Increasing sunshine will kick off a warming trend Sat-Tue.
UPDATE
Issued at 808 PM PDT Thu Apr 25 2024
Radar depicting a few scattered showers moving through the Bay Area and Central Coast this evening. Mostly very light and short- lived as seen thus far. Beyond the current precip moving through, really don't expect too much in the way of additional rainfall overnight outside of a stray light shower or two, in additional to areas of coastal and mountain drizzle as we head into Friday morning. Overall amounts this evening will be just a smattering of one to a few hundredths here and there.
SHORT TERM
(This evening through Friday)
Issued at 156 PM PDT Thu Apr 25 2024
Cloudy conditions continue, with breezy to gusty northwest wind this afternoon and evening as the upper level pattern continues to shift behind the low pressure center's passage. An additional trough passes through the area overnight, bringing widespread drizzle chances with light rain possible on higher elevations and along the coast.
Precip chances pause Friday afternoon, but cloud cover will still be persistent. Friday's pressure gradient change will make for even breezier conditions that afternoon specifically for higher peaks and along the Big Sur coast. The trough looks to be slow to exit Saturday morning with additional drizzle chances expected along with another round of light rain chances on higher elevations and along the coast.
LONG TERM
(Friday night through next Wednesday)
Issued at 156 PM PDT Thu Apr 25 2024
The new upper level pattern keeps mostly northwest onshore flow into the weekend. While the immediate coast will continue to struggle with cloud cover, most areas slightly more inland and well into the interior will see quicker clearing times. This will place most areas back into the 60s and 70s into the next work week, while the coast will stick to around 60 degree highs. By the late week, some of those more interior locations look to break into the low 80s.
Longer term models are in better agreement that the next rain maker may just stay well to the north of the Bay Area and Central Coast as the ECMWF model families have adjusted the next trough to arrive over Seattle rather than the Bay area.
AVIATION
(06Z TAFS)
Issued at 1022 PM PDT Thu Apr 25 2024
Generally MVFR to mid-level ceilings as a front passes through the region. STS has cleared out behind the cloud shield, but satellite imagery is showing expanding stratus to the north, resulting in low confidence for clear skies through the night.
Mid-level to MVFR ceilings and scattered -DZ expected to continue through at least the next few hours. Updated model output showing earlier clearing times Friday morning, but confidence in clearing time remains low. Breezy westerly winds continue overnight with strong gusts building through Friday in the post-frontal environment.
Vicinity of SFO... MVFR ceilings continue through at least 12Z with breezy west winds. Low confidence in clearing time Friday morning, but VFR conditions expected by the afternoon. Breezy west-northwest winds continue overnight and build through Friday. Gusts up to 30-35 knots on Friday afternoon, monitoring possible gusts above 35 knots but at this time, probabilities are low (10-20%).
SFO Bridge Approach... Similar to SFO.
Monterey Bay Terminals... Generally MVFR conditions with -DZ possible overnight, clearing late Friday morning. Breezy west winds building through Friday, gusting up to 20-25 knots in the afternoon.
