The high pressure system that brought warm temperatures and clear skies to the Central Coast is breaking down and being replaced by an upper low pressure system. The National Weather System released daytime highs for Wednesday, which showed both San Luis Obispo and Paso Robles reached 80 degrees. Thursday will be a different story.
With the exception of some areas across the deep interior valleys, daytime highs will trend down to the 60s, but ahead of the afternoon, fog and clouds will be widespread from the coastlines to the inland valley communities. Weather models are showing the fog will start to mix out by 9:00 a.m. and the afternoon hours will be partly cloudy to mostly cloudy.
Southwesterly winds will start to increase by the afternoon hours, ranging from 10-15 miles per hour for the beaches and coastal valleys. For the inland valleys, wind speeds could be a little higher and closer to 20 mph.
Looking ahead to Friday, there's still about a 20% chance for rain with mostly cloudy skies. If the area does receive any precipitation, it will be very light and maybe even more like drizzle.
