Forecast Discussion:

High pressure will be the name of the game through the forecast period. This pattern will result in mainly clear skies along with afternoon high temperatures in the upper 80s to low 90s. The only caveat will be some weak disturbances that will brush by/through the region resulting in breezy west-northwest winds from time to time.

Late Monday into Tuesday, a storm system will move into the Pacific Northwest and settle itself over the Great Basin. This will result in gusty southwest winds of 15-25mph Monday and Tuesday, with higher gusts certainly possible. As has been the case with the past wind episodes, not expecting widespread blowing dust, but we could see some elevated PM-10 concentrations in the afternoon, especially on Tuesday.

Even with the slightly elevated PM-10 levels in the afternoon on Monday into Tuesday, the 24-hour average value are forecast to remain in the Good AQI category. As for ozone, we are expecting values to be in the Moderate AQI category today through Sunday before lowering into the Good AQI category Monday into Tuesday, given the windy conditions.

Have a great weekend!
