A cluster of storms, including a severe storm, over Madison is moving our way. Tornado warnings have been issued for a few of these storms. They are located in the warm sector and closer to the warm front giving them more fuel and rotation to work with.

Here is a radar map that will update with time:

The warm front hasn't reached us yet with temperatures still cooling and hanging out in the 40s in some spots. Notice how Burlington and Janesville are warmer in the 60s but Milwaukee is chilly in the 40s with the lake breeze. Temperatures are expected to eventually warm Sunday afternoon with highs in the 60s, much cooler than Saturday's 80s.

Here's a current temperature map that will update with time:

As the storms near Madison move our way some severe thunderstorm warnings may be possible. It's really only this one area of storms that causing any concern so widespread warnings or a Severe Thunderstorm Watch are not expected at this time.

MILWAUKEE (CBS 58)--We had the warmest day of the year recorded on Saturday in Milwaukee with a high of 84. We could see similar temperatures on Monday along with a storm threat. In fact, we have a slight risk of severe weather for Monday, especially late in the day into the evening. But first, Sunday will feature a cooler day with highs well in the 60s, especially away from the lakeside areas. There is the chance for scattered showers and thunder as well periodically. The forecast stays a bit stormy into Tuesday but then we start to dry out and cool off by the middle of the week. Highs on Wednesday will be in the low 60s for many. There is one more chance of showers though on Friday as we head into a holiday weekend. Hard to believe.

Warmest day of the year on Saturday...

Different story on Sunday. Daytime temps struggle to get to 60.

Severe storm risk is conditional on Monday. Morning convection could help stabilize the atmosphere...
