SYNOPSIS

21/301 AM.

High pressure aloft building in over the region will bring a warming trend into early next week. While temperatures will remain below normal today, temperatures above seasonal normals will develop by Sunday. A storm system will move into northern California during next week. Most of the area will likely remain dry. The highest chances of precipitation will be for San Luis Obispo County between Tuesday and Wednesday.

LONG TERM (WED-SAT)

21/1211 PM.

For the extended, 12Z models continue to exhibit decent synoptic agreement. At upper levels, near persistent conditions will prevail on Wednesday, but the ridge will strengthen Thursday through Saturday. Near the surface, weak onshore flow will prevail on Wednesday, but weak offshore flow will develop Thursday through Saturday.

Forecast-wise, still no significant issues are anticipated. On Wednesday, there will continue to be a chance of light rain across San Luis Obispo county, but dry conditions will prevail elsewhere. Temperatures on Wednesday will be very similar to Tuesday.

For Thursday through Saturday, the building upper level ridge and weak offshore flow will allow for a warming trend across the area with temperatures peaking on Friday (in the mid 70s to mid 80s west of the mountains). Skies will remain mostly clear to partly cloudy, based on high cloud coverage. There will be some offshore winds, but the winds will be weak and localized.
