Northeast Wisconsin residents face a narrow but dangerous storm window this evening. Forecasters warn the threat may arrive faster than most people can react.
Peak Risk: 3:00 PM – 7:00 PM today. Strong to severe thunderstorms may develop rapidly. Damaging winds and large hail are the primary threats. Stay alert.
A second round of storms is building across northeast Wisconsin after scattered showers moved through the region this morning. While the morning activity was relatively tame, meteorologists say the late afternoon setup is far more concerning — and could catch residents off guard.
The National Weather Service office in Green Bay has flagged a four-hour window — 3 p.m. to 7 p.m. — during which atmospheric conditions become favorable for a few strong to potentially severe storms. The concern: once triggered, these storms could intensify quickly.

One of the biggest concerns heading into this evening is speed of development. Forecasters note that any storms that do fire could become hazardous within minutes, leaving commuters on I-41 and Highway 10 with little time to find shelter. Reduced visibility and gusty winds may create dangerous driving conditions during the evening rush hour.
There is some uncertainty in the forecast — persistent cloud cover from morning storms could limit how much energy is available for afternoon development. But forecasters emphasize the key word is “could”: if enough breaks in the clouds occur, all the ingredients for a severe thunderstorm will be in place.
What to do now: Confirm Wireless Emergency Alerts are enabled on your phone. Have a secondary way to receive warnings — a weather radio or NWS app. If you’re outdoors between 3–7 PM, have an indoor plan ready before storms arrive.
