Multiple rounds of thunderstorms and potential severe weather are on the way to Michiana. We are watching storms this morning across Minnesota, South Dakota, and Iowa closely. What happens with those storms will be a big factor in any severe weather chances for us today. As of this point, two rounds of storms are likely today. The first will be sometime in the late afternoon (the latest timing is around 5 PM). Gusty winds and small hail are possible in this round, along with heavy rain.
There is growing concern for a second round of storms later tonight. Arrival time for this round would be around 10 PM and storms would continue overnight. The primary threat here would be heavy rain and localized flooding, but if storms are able to stay isolated, then all hazards (including a tornado or two) would be possible.
More severe storms are possible on Monday and Tuesday, but there's considerable doubt as to what these rounds would look like, given how dependent they would be on today's storms. At this point, late night storms appear possible on both Monday night into Tuesday and Tuesday night into Wednesday before we dry out by Wednesday night.
Today: Two rounds of strong storms possible. High 85.
Tonight: Heavy rain and strong storms likely. Low 68.
Monday: AM thunderstorms, with more storms possible in the late afternoon and evening. High 82.
Tuesday: Scattered strong storms. Cooler. High 78.
