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.
