It's going to be a smoky start to Tuesday. Smoke continues to drift over the area due to nearby wildfires, and as a result, an Air Quality Alert will remain in place over the inland valleys in San Luis Obispo County. Those with pre-existing health conditions and sensitivity to smoke may want to limit outdoor exposure. While the alert doesn't currently cover the entire Central Coast, the smoky skies will fill in over most of the Central Coast.

Onshore flow is making a return, which means the marine layer is developing along the south coast in Santa Barbara County. Right now, there is not enough of a northwesterly push to really drive these clouds inland, but cloudy skies should gradually make their way up the coast by tonight so that San Luis Obispo County beaches could also get some of the marine layer as well. This could actually cool Central Coast cities down by at least 10 degrees Tuesday.

Daytime highs across the Central Coast will start to trend down Tuesday. The beaches will range from the 60s and 70s with warmer conditions in Avila Beach and Pismo Beach. For the coastal valleys, daytime highs are going to range from the 70s to the upper 80s. The inland valleys will still be warm, but the highest temperature is expected to reach 104, which will be in San Miguel. Other interior valleys will stay close to the mid to upper 90s.

The rest of the week shows a decrease in temperatures so the relief from the heat is finally here. High pressure will continue to weaken and move eastward, which will result in cooler conditions.
