Onshore flow is weakening Thursday, which will allow daytime highs to warm up by a few degrees.

The morning will start out partly cloudy with patchy clouds mainly along the coastline, however, this will mix out by late morning.

Daytime highs will be a few degrees warmer Thursday but technically right around average. For the coastal regions, daytime highs will range from the mid-60s for areas along the north coast, but be warmer and closer to the mid-70s for west-facing beaches like Avila, Pismo, and Shell Beaches. The coastal valleys will range from the mid-70s to the low 80s, while the inland valley communities will many be around the low to mid-80s.

Northwesterly winds continue to be a factor in the forecast Thursday. Winds will range from 10-20 miles per hour, with wind gusts up to 25 mph at their peak.

A slight cold front will move through the area Friday, bringing daytime highs down, but that will be followed by high pressure over the weekend. High pressure will develop Sunday, resulting in warmer daytime highs, especially for the inland valleys. The inland valley communities could see temperatures close to the mid-90s by Memorial Day.
