The National Weather Service reported an air quality alert at 1:20 p.m. EDT on Monday in effect until Wednesday at midnight EDT for Cass, St. Joseph, Branch, Hillsdale and Berrien counties.

An upper-level ridge of high pressure will control the forecast all the way through the end of the week, but as a suddenly flow starts to move in by the time we get to Friday and looking ahead into the upcoming weekend, we will dial-in more summer heat, and more humidity into the forecast.
