SYNOPSIS

31/220 AM.

Warm and dry conditions can be expected through most of next week. There will be some coastal low clouds and fog, but otherwise, skies will remain mostly clear. There will be gusty north winds through tonight and gusty onshore winds through most of next week.

LONG TERM (THU-SUN)

31/135 PM.

A small ridge will nose into the area from the west on Wed and Thu and hgts will rise to about 586 dam. In combination, with relaxing pressure gradients from the north indicated by LAX-BFL ECWMF projections approaching 0-1mb - this will result in the warmest days across the area. Wednesday will be a bit warmer due to some cold air advection on Thursday. Max Temp departures look to average in the 8-12 degrees above normal range across the far interior on Wednesday. Will continue to refine temperatures as we get closer.

There is a 30-50% chance of advisory level winds across interior portions Wednesday evening. This includes: Salinas Valley, I-5 corridor, & western Santa Ynez mtn range. Elevated Fire Weather conditions are possible across SW SB county late Wednesday afternoon/evening due to gusty sundowners and moderately dry conditions. Stronger than normal sea breeze will also be present through the long term due to persistent onshore pressure gradients.

Night through morning low clouds are expected across the csts through the period. The vlys will likely wake up to stratus on Saturday and Sunday. Some beaches may struggle to clear on Fri, Sat, and possibly on Sunday. This is due to moderate to strong onshore flow combined with decreasing heights as an upper low swings across the PACNW Friday into the weekend. This will result in temperatures 3 to 6 degrees below normal for most areas Saturday into Sunday.
