3 Things To Know:
- Severe thunderstorms are likely late Wednesday afternoon, mainly north of Madison and Milwaukee.
- Heavy rain could lead to urban and small stream flooding, particularly overnight into Thursday.
- Hot and humid conditions are on the horizon early next week.
Weather conditions in Southeast Wisconsin are expected to change as we head into late Wednesday. According to the latest National Weather Service Area Forecast Discussion, a low pressure system and associated cold front will bring a risk of severe thunderstorms to the area.
Thunderstorm Timing and Threats
Thunderstorms are forecast to develop late Wednesday afternoon and evening as warm, moist air moves into the region. The primary threats from these storms will be damaging winds and large hail, particularly in areas north of Madison and Milwaukee. As the storms progress into the evening, the focus may shift towards locally heavy rainfall, which could result in urban and small stream flooding.
As the NWS notes, these conditions could lead to a risk of flooding:
“A low end severe threat for damaging winds and large hail is forecast mainly north of Madison and Milwaukee.”
Thursday’s Forecast
On Thursday, scattered storms are expected to continue as the cold front moves through. Although the severe threat decreases, the potential for urban and small stream flooding remains a concern due to lingering moisture and localized heavy rain.
Looking Ahead
As we move into the weekend, conditions will stabilize with high pressure returning. However, early next week promises a shift back to hot and muggy weather, with afternoon heat indices possibly reaching the 90s. This change underscores the importance of staying updated on conditions as we navigate this weather transition.
