Offshore flow will bring a warming trend to the Central Coast Wednesday.
Ahead of the afternoon, foggy conditions are fairly widespread over coastal valleys and beaches with most of the marine layer concentrated over the central and south coast regions of Santa Barbara County.
After the fog mixes out by late morning, daytime highs are expected to significantly heat up, especially for coastal and inland valley locations. Across valley locations, peak temperatures will range from the low 80s to the mid-90s. For context, San Luis Obispo is expected to reach 92 degrees Wednesday, which is nearly 20 degrees above average for this time of the year. Along the coast, temperatures could reach the the upper 70s and low 80s.
The warm-up will continue through Thursday before temperatures plummet into the 50s and 60s Friday, Saturday, and Sunday. By Friday, a low pressure system will bring cold daytime highs and a chance of rain to the Central Coast. The European Model is showing that scattered rain is possible Friday night through Saturday morning and again on Sunday. As far as rain potential goes, it's looking like the Central Coast could receive 0.10''-0.33'' over the three-day period. The rain chances will continued to be monitored as the end of the week approaches.
