SYNOPSIS

03/209 AM.

A weak low pressure system will bring cooler weather to the area today. It will remain cool on Monday and Tuesday with a slight chance of drizzle or a light shower. Gusty onshore winds are expected at times. Dry and warmer conditions are likely Wednesday through next weekend.

LONG TERM (WED-SAT)

03/242 AM.

Weak ridging builds into the state on Wednesday and persists through Friday before turning into dry NW flow on Saturday. As is typical for May there will be moderate to strong onshore flow to the east through the period. Many of the csts and some lower vlys will likely have night through morning low clouds and fog. Hgts are not too high so the fog will likely not be dense. Aside from the low clouds skies should be mostly clear. The strong push to the east will bring moderate seabreezes and gusty afternoon winds in the Antelope VLy.

Look for massive warming Wednesday as sunny skies and rapidly rising hgts combine to bring 3 to 6 degrees of warming across the csts; 5 to 10 degrees across the vlys and 10 to 15 locally 18 degrees across the mtns and far interior. Thursday will see continued warming with most areas picking up an extra 4 to 8 degrees. Another 1 to 3 degree added to the max temps on Friday will bring the beaches up to the lower 70s with mid 70s to lower 80s further inland. The vlys will be in the mid 80s to lower 90s. 90s will be common across the far interior and lower mtn elevations. Cstl temps will be about 6 degrees over normal and the rest of the area will mostly be 8 to 12 degrees above average. Continued warm over the weekend with little day to day change in the temps.

SCA conditions are most likely near the Channel Islands and across the Santa Barbara Channel.

Also, there is a 30% chance for SCA winds across the nearshore waters along the Central Coast during the aforementioned timeframe.

From Wednesday through Friday, winds are expected to increase each day across the Outer Waters and along the Central coast. SCA winds are possible on Wednesday, and likely Thursday into Friday. These winds could impact western portion of SB Channel by then.
