The start to the weekend will include daytime highs that are beginning to trend down as well as smoke-filled skies.
An Air Quality Alert continues to remain in place for San Luis Obispo County as northwesterly winds carry wildfire smoke from fires burning in Monterey County. According to the Santa Barbara County Air Pollution Control District, an Air Quality Warning is in place as smokey skies are also impacting Santa Barbara County. Per these alerts and warnings, it's advised that those with sensitivities or pre-existing health conditions should use caution when it comes to the amount of time spent outdoors.

A heat advisory is still in effect through 10 p.m. for the Santa Ynez Valley and parts of the Cuyama Valley. Daytime highs across the area could range from the mid-90s to the low 100s.
The high-pressure system that has been bringing the heat to the area is continuing to shift in an eastward direction, which will result in cooler daytime highs heading into the weekend. The inland valleys will have a mix of 90s and low 100s while most coastal valley locations will be cooling down to the 80s and 90s with the exception of the Santa Ynez Valley. The beaches are also trending down as daytime highs will be closer to the 70s and 80s Friday.
As daytime highs trend down, there's another chance of thunderstorms over the weekend. This is due to Tropical Storm Genevieve, which is currently near Baja California. The storm will continue to move towards the Southern California Coast, and as it loses fuel from cooler waters it will continue to dissipate, which could result in instability. Right now, it looks as if the chance for thunderstorms will mainly be over the mountains and foothills in San Luis Obispo and Santa Barbara Counties but it's still possible other regions could also experience some precipitation.
