Summer like temperatures are expected through the weekend with increased humidity. Be prepared for the warmer temperatures if outdoor activities are planned. Be sure to drink plenty of water and take frequent breaks if spending a lot of time outside. There is a chance for thunderstorms on Thursday mainly along and north of I-69, but otherwise great weather heading into the weekend.
The building of an upper level ridge across the eastern US by the end of the week will establish a period of very warm weather across the Great Lakes. This warm weather will not only persist through the weekend, but possibly well into next week. Normal high temperatures this time of year across Southeast Michigan range from 69 to 72 degrees.
