Forecast Discussion
Thursday: AIR QUALITY ALERT! Upper level ridging and surface high pressure will remain in place for another day. Temperatures are expected to be a couple of degrees warmer than on Wednesday and reach the mid 90s. Winds will be light and variable, which will not allow for much atmospheric mixing. The air mass will be slightly drier than the last couple of days as well with skies mostly clear. These conditions are expected to allow Ozone to climb into the ORANGE range, which triggers an Air Quality Alert. PM2.5 is expected to remain in the YELLOW range. ML
