There's quite a bit happening in the weather pattern Wednesday.
Starting with the morning commute, drivers in Lompoc, Vandenberg and Santa Maria areas can expect a foggy drive. A dense fog advisory will remain in place over those areas through 10:00 a.m. During this time, visibility could be lowered to a quarter mile or less, so drivers should have headlights on and increase following distance.
By the afternoon, daytime highs are going to be heating up for the inland valley communities in San Luis Obispo County. A heat advisory will go into effect at 10:00 a.m. and expire at 8:00 p.m. Daytime highs across the interiors will range from the low 90s to the low 100s Wednesday, which means daytime highs will be 10 to 15 degrees above average.
Clouds will be moving in a northerly direction from Los Angeles and Ventura Counties, which could have local impacts. There's about a 20% chance the mountains and foothills in Santa Barbara County, Cuyama Valley, California Valley and eastern San Luis Obispo County mountains could experience thunderstorms Wednesday.
The upper level low that continues to rotate off the coast is expected to move northeast Thursday, which will ultimately result in cooler temperatures and the chance for morning drizzle.
