3 Things To Know:
- Showers and thunderstorms are likely Wednesday afternoon into the overnight, with a 60-80% chance.
- Heavy rainfall is expected, with amounts of 1 inch or more possible in some areas.
- Warm temperatures will return this weekend, with highs potentially reaching the upper 80s to low 90s.
Wednesday: A Stormy Afternoon Ahead
Wednesday will bring a significant change in weather for Western Wisconsin. Expect showers and storms to develop primarily in the afternoon and continue into the overnight hours. The National Weather Service indicates a high likelihood of storms, with chances ranging between 60% to 80%.
Locally heavy rainfall is anticipated, particularly along a boundary that will be moving southeast through the region. Rainfall amounts of 1 inch or more are quite possible, and localized areas could see totals between 2 to 3 inches. Given these conditions, there could be flooding concerns, especially in areas that experience multiple rounds of rain. Areas north of I-90 may be at greatest risk for those higher amounts.
As stated in the forecast discussion, “Heavy rainfall is expected to continue along this boundary given favorable PWATs in excess of 1.7 inches…” This atmospheric setup suggests the potential for strong to severe storms as well, with damaging winds being the primary concern.
Conditions into Thursday and Beyond
The storm threat will gradually diminish, but the risk for more localized flooding remains, particularly in the north-central parts of the state. Transitioning into the weekend, conditions are expected to change as warm air moves in.
Temperatures are forecasted to rise, reaching the upper 80s to low 90s, along with increasing humidity. This means warmer and muggy conditions are on the way, creating a typical summer feel.
Stay Prepared
Given the potential for severe weather and heavy rainfall, it’s a good idea to keep an eye on forecasts in the coming days. Make sure you have a plan in place should storms impact your area.
