Justin Liles: Thunderstorm chances tonight, colder conditions coming

Warm temperatures and breezy southerly winds today give way to increasing chances for showers and thunderstorms this evening. Isolated severe thunderstorms are possible early tonight in northwestern Wisconsin as well. It looks like the majority of the storms may not arrive until after 10pm. We could hear some thunder and possibly see some lighting along with smaller hail.

A cold front then brings decreasing temperatures tonight with a return to more fall-like weather for the rest of this week. Light snowfall accumulations are possible towards the end of this week in far northern Minnesota and the lake effect snow belts in northwestern Wisconsin. The U.P. of Michigan may see some snow too.
