Both the San Luis Obispo County Air Pollution Control District and Santa Barbara County Air Pollution Control District are reporting unhealthy air quality for Wednesday.

An air quality alert remains in place for SLO County through Thursday as levels of air quality range from "unhealthy for sensitive groups" to "unhealthy." For the "unhealthy" tier, it's possible that everyone in that area could be impacted by the smoke in the atmosphere, while the "unhealthy for sensitive groups" tier will mainly impact those with pre-existing health conditions or sensitivities. Santa Barbara County will have "moderate" to "unhealthy for sensitive groups" levels Wednesday.

A ridge of high pressure will bring slightly warmer temperatures Wednesday before an upper level low sweeps in from the Pacific Northwest Thursday. The low should actually help move smoke out of the area by producing southwesterly flow. In addition, it will bring increased cloud cover with the possibility of light precipitation in the form of mist as well as cooling.

Wednesday's daytime highs will be slightly warmer with temperatures across the inland valleys from the low to upper 90s with the possibility that San Miguel could reach triple digits. The coastal valleys will stay close to the 70s and the beaches will be right around the 60s and 70s.

Winds will continue to be mild Wednesday with speeds staying right around 10-15 mph. Towards the south coast and between Gaviota and Refugio, expect winds to peak at 20 mph Wednesday afternoon and 25 mph by Wednesday evening.
