Cold front to come through Ann Arbor Wednesday night, severe thunderstorms possible

By Katrease Stafford

The days of warm weather may be numbered in Ann Arbor, thanks to storms and a cold front that will come through the area Wednesday night and last through the weekend.

Showers and thunderstorms will move through the area Wednesday night, bringing in a cold front and much cooler temperatures.

Wednesday's high will reach around 91 degrees, but with a 62 percent chance of thunderstorms this evening, the temperature will drop overnight to a low of 65.

Matt Mosteiko, a National Weather Service meteorologist in White Lake, said the storms may be severe with strong wind gusts up to 60 mph and hail.

Overnight, the chance for showers drops to 30 percent, but the cooler temps will stick around.

"Three different waves of cold air are coming through the Ann Arbor area," Mosteiko said. "Yesterday was really hot, but you're going to see a pretty significant temperature drop over the next few days."

Mosteiko said the recent warm weather was brought through by an air mass coming from the Gulf of Mexico and will be replaced by a cold, dry Canadian air mass.

Thursday's temperature will reach 76 degrees, but by night, the temperature will drop to 46 degrees.

Friday, the high will be 59 degrees, with a low of 37 degrees that night. Saturday will be slightly warmer with a high of 61 degrees and a low of 50 degrees. Sunday will have a high of around 68 degrees.

"It looks like it's going to cool down for an extended period of time, at least through the weekend," Mosteiko said. However, Mosteiko said he wouldn't rule out a possible return of warm weather to Ann Arbor. Mosteiko said temperatures might begin to rise again by next Tuesday or Wednesday.
