LANSING, Mich. — Comfortable weather hangs on this evening as high pressure maintains its grip over the Great Lakes. Sunny skies during the evening will remain clear overnight, with lows dipping to around normal in he low 60s. Humidity remains low for the time being, but that will not be the case as we head into the second half of the week.

A warm front lifts out of the central U.S. and across Michigan on Wednesday, ushering in our next wave of high heat and humidity. Our atmosphere will remain stable enough to keep showers and thunderstorms out of the picture for now, but that means no natural cooling from highs climbing to around 90 degrees. Humidity will be slow to increase during the day, but should still be enough to push heat indices toward the mid-90s in the afternoon.

Thursday trends even hotter and more humid with highs heading for the mid 90s. Add in the humidity and heat indices will likely climb to around 100 degrees. There is the potential for some cloud cover to roll in during the afternoon and limit some of the heat, but make sure to keep cool and hydrated regardless.
