It is going to be Tuesday, which has prompted a heat advisory. Both San Luis Obispo and Santa Barbara Counties are under the advisory that will last from 10:00 a.m.-8:00 p.m. Not only do the inland valleys have the potential to reach triple-digits, but the coastal valleys will range from the low to mid-90s. For those at the coast, don't expect too much relief from the heat as daytime highs are expected to peak around the mid-80s.
Skies will be clear by the afternoon, but there's a possibility some patchy marine layer and fog could linger along the coast before sunrise. Breezy Santa Lucia winds will continue to be in the forecast Tuesday, ranging from 10-20 miles per hour through Tuesday night, which will help keep the skies clear.
The big shift in the weather pattern will happen Thursday when temperatures cool by five to 15 degrees and the possibility of rain makes its way back into the forecast. Most of that rain is expected for southern California, but it's possible the Central Coast and South Coast regions could get some light rain and drizzle Thursday through Saturday.
