Good Sunday, everybody. January is wrapping up on a rather opposite note compared to how we spent much of the month. Mild temps today will carry over into the first few days of February, before much colder changes thunder into the bluegrass state. That thunder threat could even lead to some severe weather.

Let’s start with today and roll forward.

Highs will be back in the 60s for many as clouds increase. Those clouds will eventually produce some showers later today as a cold front works in. The simulated radar from the Hi-Res NAM shows the action tonight and then moving away by Monday afternoon…

Temps on Monday will be much cooler than this weekend, but will still be above normal.

Much milder air surges back in for Tuesday as a huge storm develops across the plains states. That works into the Great Lakes by Tuesday night and drags a cold front into our region. A line of thunderstorms develops along this front and some could be severe…

This setup, while still threatening, isn’t as potent as what the GFS was suggesting a few days ago. The Canadian Model still has the potent look…

Where this line of storms develops, heavy rainfall is a good bet. Here’s the GFS rain forecast…

Much colder air comes in behind this system for Wednesday and the air grows gradually colder through the end of the week. Many of the models are now showing a clipper type system diving in here with true arctic air to start next weekend…

That could be a snow maker with gusty winds and bitterly cold temps blowing in.

The system behind that continues to be the one that stands out. This is a threatening look from the GFS at 500mb…

I will have additional updates later today. Your radars will help you track the late day showers into the region…

Enjoy your Sunday and take care.
