SYNOPSIS
Issued at 142 PM PDT Thu Apr 18 2024

A touch cooler Friday as a weak system moves through. Chance for light drizzle for coastal areas the next couple of days. Temperatures rebound late weekend and early next week. Chance for light rain enters the forecast mid next week.

SHORT TERM
(This evening through Saturday)
Issued at 142 PM PDT Thu Apr 18 2024

Increased cloud cover today along coastal areas south of SF as the marine layer deepens ahead of the approaching weak trough. Still looking like a progressive, open wave, this system will scoot through rather quickly Friday, bringing additional cloud cover and a slight chance for drizzle along coastal locations and higher elevations of the East Bay Friday and Saturday mornings. The other impact from this system will be the breezy NW winds that develop along the coast as the system departs. Generally looking at gusts of 25-30 mph along the immediate coast Saturday afternoon into Sunday afternoon.

LONG TERM
(Saturday night through next Wednesday)
Issued at 142 PM PDT Thu Apr 18 2024

By Sunday, ridging dominates the pattern once again with temps warming back into near 80 for inland areas and 60s to near 70 along the coast. Similar picture into Monday as well. Tuesday brings some changes. Ensemble guidance continues to advertise anomalous troughing over the EPac/West Coast during the mid-to- late next week period, hinting at a pattern that promotes above average precip and below average temperatures. Average precip for the second half of April for our region is roughly a half inch, give or take a few tenths depending on if you're coastal or inland. What we're expecting next week is generally on the order of a trace to a few tenths here and there. Longer terms guidance does show the pattern continuing into next weekend, where there could be additional light rainfall, bringing us into that ballpark of slightly above normal. The main caveat with this forecast is that while there is moderate to high confidence in the overall pattern, the confidence in widespread measurable rainfall is low. In fact, in a grouping of 100 different models, roughly 24 of them advertise any measurable precip for us at all through next weekend. The answer to the question of next week being widespread light rain or just some increased cloudiness and drizzle will need further refinement in future forecasts. For now, plan on the latter half of next week being cool and damp.

AVIATION
(00Z TAFS)
Issued at 445 PM PDT Thu Apr 18 2024

VFR through the remainder of the day with the exception of KMRY where the stratus straddling the coast, has moved over into the terminal causing MVFR conditions. The remainder terminals will start to see flight conditions lowering into MVFR/IFR tonight (with the exception of KSJC and KLVK, where VFR is expected to prevail)into the early morning hours, with low to moderate confidence of LIFR conditions in North Bay and Monterey Bay. Most terminals start to improve to VFR near 16-17Z. Moderate to breezy winds are expected to diminish overnight and rebuild Friday morning.

Vicinity of SFO...VFR through the remainder of today with possible MVFR conditions near 13Z but moderate confidence on ceiling height.
If conditions remain dry, there is a chance for VFR through the TAF period. Breezy onshore winds will start to diminish to light winds tonight before becoming breezy again Friday afternoon.

SFO Approach Bridge...Similar to SFO.

Monterey Bay Terminals...VFR with breezy onshore winds. Moderate confidence that IFR/LIFR conditions will return tonight into early Friday morning. VFR will prevail after 17Z. Light variable winds overnight before rebuilding Friday morning.

MARINE
(Tonight through next Tuesday)
Issued at 445 PM PDT Thu Apr 18 2024

During early next week, near gale force winds are possible across the outer coastal waters. Wave heights will start to build heading into the late weekend before diminishing by mid-week. Another moderate period northwest swell arrives over the weekend as well as another light, longer period (18 seconds) southerly swell.
