New SYNOPSIS, SHORT TERM, LONG TERM

SYNOPSIS
Issued at 1206 PM PDT Wed Apr 17 2024

Warm temps persist into the weekend with a slight cool off Friday as a weak trough pushes through. Increased cloudiness late week with a chance of coastal drizzle. Otherwise seasonal going into next week.

SHORT TERM
(This evening through Thursday)
Issued at 1206 PM PDT Wed Apr 17 2024

Mostly clear conditions today with some highs clouds streaming across the region. Not much change going into tomorrow. High temps Thursday look to be pretty much on par with what is being seen today, perhaps a couple of degrees cooler near the coast as the ridge begins to break down.

LONG TERM
(Thursday night through next Tuesday)
Issued at 1206 PM PDT Wed Apr 17 2024

Going into late Thursday, the high pressure ridge holding us steady for the last few days begins to break down with the approach of a weak trough embedded in the in the northwest flow.
Guidance has been fairly consistent in depicting this disturbance as a weak, open wave that passes through fairly quickly. The main effects will be a slight cooling of high temperatures for Friday and increased cloud cover, especially for coastal areas. Overall temps look to be about 3-5 degrees cooler on Friday than they were on Thursday. The main factors here are increase onshore flow and cloud cover. Deepening of the marine layer will also contribute to a slight chance for patchy drizzle Friday and Saturday mornings, especially near favored NW facing orographic areas near the coast.
Beyond Saturday, the ridge builds again going into the early part of next week with temperatures remaining right around seasonal normals. In the longer term, ensemble guidance advertises another trough affecting the region by the middle of next week, but it is unclear if this will be an efficient rain maker or not. Currently about 25% of ensemble members reflect any measurable rain at all for the area, so will need to wait for future forecasts to refine any details.

AVIATION
(18Z TAFS)
Issued at 1033 AM PDT Wed Apr 17 2024

VFR will prevail through this evening with largely diurnal breezes at all terminals
Tonight
MVFR and potentially IFR ceilings and/or visibility is forecast at all terminals except LVK and APC. Confidence is low to moderate in the ceiling/visibility parts of the TAF.

Vicinity of SFO...VFR will prevail as the NE'ly SF Bay breezes become more NW'ly through the afternoon. Speeds will range between 10-15 knots with moderate to high confidence in the winds forecast. Winds subside below 5 knots around 04Z which may allow for some flexibility for rwy configs. VFR cigs around FL200 will continue to stream in overhead. Between 12-16Z, intermittent MVFR cigs around FL025 are forecast as NE'ly SF Bay breezes return.
Confidence in MVFR is low to moderate. VFR is forecast to return by 18Z Thu with NE'ly SF Bay breezes becoming NW'ly.

SFO Bridge Approach...MVFR cigs may obscure approach 11-18Z Thu.
Otherwise, similar to SFO.

Monterey Bay Terminals...VFR currently, however, the best opportunity of IFR visibility and/or ceilings reside here.
Diurnal breezes under 15 knots are forecast to dominate through the TAF period. The window in which the IFR probability (around 30-40%) peaks at MRY between 10-14Z with chances of IFR at SNS under 20%. Intermittent MVFR cigs should lift by 15Z at SNS. VFR is not forecast to return until after 18Z Thursday at MRY.
