The main weather impact of this forecast period will be the building heat through the beginning of next week. Highs build to the upper 80s to low 90s with dew points in the 60s. Additionally, lows in the 70s will make it harder to get relief from the heat. While widespread rain and severe thunderstorms are not expected, there will be near-daily slight chances (15-30%) of afternoon showers and thunder.
Heat and humidity gradually build this weekend with the hottest temperatures expected to arrive across much of Michigan beginning early next week.
