SYNOPSIS

13/1205 AM.

Scattered rain and mountain snow showers will continue at times through the afternoon, mainly over the interior and the Central Coast. Dry and warmer weather is expected the rest of this week.

LONG TERM (THU-SUN)

13/314 AM.

An inside slider is expected to work its way down the state line on Thursday, followed by dry NW to N flow on Friday. Thursday morning will feature onshore flow to the east and offshore flow from the north. On Friday there will be weak offshore flow from both the north and east in the morning.

There will not be much wind on Thursday, but Thursday night and Friday decent north flow will develop in the mtns with advisory level gusts likely through the I-5 corridor and the Santa Barbara county mountains.

Max temps will not change much on Thursday, but the offshore flow will bring 2 to 4 degrees of warming to most of the area on Friday.

On Saturday the upper flow turn westerly. There will still be some offshore flow at the sfc, but with no upper support it will only generate sub advisory canyon winds. Max temps will respond to the continued offshore flow and 3 to 5 degrees of additional warm seems likely. This will bring max temps up into the upper 70s to mid 80s for most of csts/vlys which is 4 to 8 degrees above normal.

Mdls are struggling a bit with the pattern for Sunday. All mdls show a large upper low spinning somewhere to the NW but there is massive disagreement on the location. For now the forecast is similar to Saturday with just a little cooling across the csts as the offshore flow weakens.
