SYNOPSIS

22/1146 PM.

Skies will be mostly clear today and Friday. Look for warming today then cooling with a stronger sea breeze on Friday. Continued cooling Saturday with a chance of occasional light rain. Warmer Sunday and Monday. Then, another weak storm may bring light rain to the area around Tuesday.

LONG TERM (SUN-WED)

23/225 AM.

There are enough ensembles that lag the system enough to allow for a slight chc of morning rain. The forecast should be thought of as an "80 percent chc of no rain". Otherwise, the departing system will leave clearing skies and warmer temps in its wake. It will likely be pretty breezy in the afternoon as the onshore push to the east will be approaching 8 mb.

Dry westerly flow will set up over the area on Monday. Enough mid level clouds will drift over the area to make it a partly cloudy day. Max temps will bump up 2 to 4 degrees and max temps will end up in the mid to upper 60s across the csts and lower 70s in the vlys.

The mdls are much less enthusiastic about Tuesday's system and a 20 percent chc of rain might even be generous. The AI mdls are hinting that the best chc of rain will occur in the evening.

For Wednesday, the deterministic GFS and its forecast of a big honking upper low just off the coast has been discounted and prefer the AI-solutions with the less huge upper low further off to the SW. It should be a fairly benign weather day with max temps coming in a few degrees blo normal.

SCA level winds are expected this afternoon and evening across the western half of the Santa Barbara Channel and near the Channel Islands. There is a 60-70% chance SCA winds occur across the aforementioned waters Friday afternoon/eve. For Saturday through Monday, winds and seas are generally expected to remain below advisory levels.
