SYNOPSIS

15/855 PM.

Warm but below normal temperatures will continue through Thursday, with expanding coastal morning low clouds. Patchy morning drizzle will be possible during the night into morning hours through Thursday. Temperatures are likely to increase towards the end of the week.

LONG TERM (SAT-TUE)

15/1204 PM.

Not much going on in the xtnd very weak ridging moves into the area Friday and continues into Saturday hgts may approach 588 dam. Mdt onshore flow will continue to the east. There will be weak offshore flow in the morning from the north but it will turn to weak onshore flow in the afternoon. The morning offshore push should reduce (but not eliminate) the morning low cloud coverage. Look for 2 to 4 degrees of warming each day. This will lead to max temps in the 70s and lower 80s across the csts and 80s in the vlys on Saturday. Despite the warming these max temps are still 2 to 4 degrees blo normal.

A weak upper low will move into the area Sunday and Monday. It currently looks to be moisture starved, although it should provide sufficient dynamics to gin up a deep marine layer and perhaps some morning drizzle or a passing shower.

Although the exact weather pattern becomes more uncertain, we have fairly high confidence that benign weather will prevail into the middle part of next week.

High confidence in relatively light winds across all coastal waters through Thursday morning. SCA level NW winds will return to outer waters south and west of Point Sal by Thursday evening. These winds will become fairly widespread across the Outer waters reaching into the nearshore waters along the Central Coast and at least the western portion of the Santa Barbara Channel Friday into the weekend. Peak winds will be much weaker than this past weekend likely topping out 20-25 kt & locally 25-30 kt over climatological favored waters such as near Point Conception.
