Severe Thunderstorm Potential This Evening - Updated 755 PM

We will be closely monitoring the progression of upstream storms in northeast Iowa this evening. Thsese storms have a history of wind damage.

So the main threat will be strong and damaging straight-line winds and possibly large hail. An isolated tornado can't be ruled out. We believe areas south and west of a line stretching from about Baraboo to Madison to Delavan have the higher chance for seeing severe weather. The risk will fall off to the north and east due to cooler and drier air in that region.

Radar

The reason for this activity is the approach of a warm front from the south. The front pushes into southwest Wisconsin this evening, then moves north overnight. This sets the stage for a very warm and humid day on Tuesday (highs in the mid 80s!).

Front position at 7 pm this evening

Front position at 7 am Tuesday Morning

Remain alert for updated forecasts today. Use the radar imagery below to monitor how the storms develop upstream of Wisconsin this evening, then move into southern Wisconsin later this evening. Be ready to seek shelter if necessary.
