Tuesday evening forecast May 4

Warm valleys and a pleasant coastline will continue through Wednesday, due to high pressure aloft. The ridge of high pressure will shift east late Wednesday, with cooling ahead. As an area of low pressure will sink further south, prompting stronger onshore flow and a gradual cool down through the weekend. This could lead to more cloud cover and tough clearing for some coastal areas.

Despite warm valleys the weather pattern will remain quiet through out the week. High pressure will remain in control until Wednesday, with a stronger marine layer for the later half of the week. By late Thursday the sweeping trough could bring gusty northeast winds along the Central Coast and into southern Santa Barbara County until Friday.

As onshore flow strengthens by the end of week, low level clouds will become more extensive. This will bring a much needed relief across the interior valleys as temperatures will drop and clouds will be difficult to clear.

Daytime highs along the coastline will warm in the mid 60s to low 70s through Wednesday. Valleys remain very warm for one more day, as conditions will warm in the low to mid 80s. Further cooling expected through the weekend with most areas warming in the 60s to 70s.
