3 Things To Know:
- Peak afternoon heat indices today range from the mid to upper 90s, particularly in east-central and far northeast Wisconsin.
- Periodic chances for showers and thunderstorms will occur through the holiday weekend, with a possibility of strong to severe storms this evening.
- Flood Watch remains in effect for central and east-central Wisconsin due to potential heavy rainfall.
As we step into the holiday weekend, all eyes are on the forecast for Northeast Wisconsin. According to the latest update from the National Weather Service in Green Bay, we’re facing elevated heat indices today along with the threat for thunderstorms.
Hot & Humid
Many areas are experiencing unseasonably warm temperatures today with highs reaching the mid to upper 80s. However, it’s the humidity that’s really elevating our discomfort. Peak afternoon heat indices are expected to hit the mid to upper 90s today.
Thunderstorm Outlook
This afternoon and evening, thunderstorms may form as a stationary boundary lingers just south of Northeast Wisconsin. While most of the daytime should remain dry, we cannot rule out the chance for a few strong to severe storms developing later today.
“If strong to severe storms develop, damaging winds, hail, and heavy rainfall will be the main concerns.”

Holiday Weekend Forecast
The storm chances won’t just end today. Over the holiday weekend, additional rounds of showers and storms could affect the region. A slightly stronger weather system is expected to pass through between late Friday night and Sunday, potentially bringing heavy rain. While we anticipate rainfall, the severe potential will depend on timing and placement of the related surface low.
Looking Ahead
Following the holiday weekend, there appears to be a trend towards drier weather for the first half of next week. We’ll keep monitoring for any changes in forecasts as conditions evolve.
