New UPDATE

SYNOPSIS
Issued at 228 PM PDT Wed Apr 24 2024

A deep marine layer and expansive cloud coverage will keep temperatures cool through Thursday before stronger winds arrive Friday. Clearer skies and slightly warmer temperatures are expected this weekend.

UPDATE
Issued at 853 PM PDT Wed Apr 24 2024

Areas of the North Bay coast, East Bay Hills and Santa Cruz Mountains saw light rain/drizzle today with amounts totaling up to 0.04". Due to abundant cloud cover, temperatures struggled to warm out of the low-to-mid 60s. Similar conditions will be possible overnight, but rainfall amounts won't amount to much and are likely to range from trace amounts to a few hundredths of an inch.
Overnight temperatures are expected to cool into the mid 40s to low 50s. No updates are anticipated at this time.

SHORT TERM
(This evening through Thursday)
Issued at 251 PM PDT Wed Apr 24 2024

Another cloudy and cool afternoon, but with a slightly different setup compared to yesterday as the the low pressure has moved closer to the coast. While the low continues to push plenty of clouds onshore cloud heights and marine layer thickness increased as the low moved closer. What does that mean? Well it will be slightly harder for the cloud cover to erode this afternoon.

The low pressure slowly makes its way inland tonight. The deeper marine layer may limit fog development to only a few patches in the North Bay, otherwise expect another cloudy night followed by a cool and cloudy Thursday.

While Thursday continues the trend of cloudy skies, the upper level pattern shifts, allowing for more northwest flow and bringing back some breezier northwest winds into the forecast.

LONG TERM
(Thursday night through next Tuesday)
Issued at 251 PM PDT Wed Apr 24 2024

Still cloudy and cool with some pockets of drizzle for early Friday as the low pressure exits and the marine layer compresses just enough for lower clouds. Friday's pressure gradient change from the low's exit will make for even breezier conditions for Friday specifically for higher peaks and along the Big Sur coast. The more active winds will allow for better clearing of cloud coverage in the late afternoon

While the new upper level pattern still allows for onshore flow, cloud cover becomes less pervasive. 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.

Longer term models still struggle with the next pattern change at the beginning of next month. While the ECMWF families place rain chances back into the forecast, others favor more cloudy and drizzly conditions, and a few keep the moisture well to the north.

AVIATION
(00Z TAFS)
Issued at 510 PM PDT Wed Apr 24 2024

VFR at all terminals with MVFR to return by late this evening.
Broken to overcast conditions should remain in place for the majority of the TAF period with ceiling heights decreasing heading into the evening hours. As the night progresses, an upper level low will continue to exit the region and a shortwave ridge will start to build this will help to compress the marine layer and push ceilings down to low-end MVFR. West to northwest winds will start to pick up mid to late tomorrow morning with gusts up to 25 knots possible.
Gustier conditions will then continue through the end of the TAF period and into the next.

Vicinity of SFO...VFR transitioning to MVFR overnight. Transition to westerly flow has been pushed back slightly with obs showing breezy southwesterly winds continuing. Winds are expected to gradually shift more westerly heading into the evening hours and continue through the end of the TAF period. Winds will start to pick up mid to late tomorrow morning with gusty conditions expected through the end of the TAF period. Gusts up to 25 knots are currently expected.
T he caveat to this is that recent guidance has shown winds trending higher than previously forecast which may result in gusts needing to be upped in future TAFs.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Currently VFR with moderate to high confidence in transition to MVFR overnight. Gusty conditions at MRY continue heading into the evening with winds expected to weaken and become more moderate overnight. For both MRY and SNS, westerly winds prevail through the TAF period with moderately gusty winds returning by mid to late tomorrow morning.

MARINE
(Tonight through next Monday)
Issued at 853 PM PDT Wed Apr 24 2024
