3 Things To Know:

- A Heat Advisory is in effect for Wednesday as temperatures soar into the 80s and 90s.
- Thunderstorms are possible Thursday afternoon, some may be strong to severe.
Tuesday
High pressure is settling over Northwest Wisconsin, leading to dry conditions tonight. Travelers can anticipate lows in the 50s and 60s, especially cooler near Lake Superior. There is only a slight chance (20% or less) of an isolated shower or storm this afternoon and evening across parts of northeastern Minnesota, but most areas will remain dry.
Wednesday: Heat Advisory in Effect
Tomorrow marks a very warm and humid day. We can expect highs in the 80s and lower 90s, with dew points in the 60s, making it feel quite muggy. The National Weather Service has issued a Heat Advisory for much of the region from noon to 7 PM CDT. This alerts residents to elevated heat risk conditions.
“Widespread Moderate HeatRisk conditions across the region for Wednesday along with WBGTs above 79F from late morning through late afternoon.”
While there is a slight chance of isolated showers or thunderstorms, the limited shear and lingering smoke aloft may prevent significant storm development. Most areas will likely remain dry through the day.
Thursday: Increasing Thunderstorm Chances
Temperatures will remain warm and humid into Thursday. However, as the upper ridge shifts east, we will see increasing chances for showers and thunderstorms, particularly in the afternoon. Some storms may be strong to severe, particularly in western areas of the region, with shear expected to improve, reaching 30 to 40 knots.
Residents should stay alert for potential severe weather alerts as this unfolds later in the day. Rain chances will persist into Friday before drying out over the weekend.
Looking Ahead
Friday and the weekend are expected to bring cooler temperatures in the 70s and low 80s with limited chances for precipitation. As the jet stream shifts north of the border, the main storm track will also be displaced, leading to dry conditions.
