The big story this Tuesday is the thick smoke drifting across the Treasure Valley from Oregon wildfires. As of early evening the Valley is still experiencing "Very Unhealthy" air quality due to the smoke. More smoke will fill the valley on Wednesday with poor air quality highly likely once again.

Reminder that the Treasure Valley is still under an Excessive Heat Warning through Wednesday. Temperatures across the Valley floors will be in the triple digits. Start hydrating now if you are spending long periods of time outdoors for work.
A cold front Wednesday will trigger strong thunderstorms, potentially producing small hail, 70 mph outflow winds, and brief heavy rain. The lightning could worsen the current fire situation. A Red Flag Warnings has been issued for Wednesday afternoon and evening due to the likelihood of lightning.

After the cold front passes Wednesday, temperatures will cool back to the 90s on Friday bringing much needed relief to the heat and potentially some temporary relief from the smoke.
