Starting this evening into tonight, expect scattered showers and storms to bring localized heavy rainfall to the area, especially in central Wisconsin where localized urban flooding is possible. Next, a warm front is expected to lift northeast across the area late Tuesday night into Wednesday morning, which may bring a few strong to severe storms. Then, after a hot and humid day, a greater risk for severe weather arrives late Wednesday afternoon into the evening, where all severe weather hazards are possible. Finally, another round of severe weather is possible Thursday afternoon into the evening, but details are uncertain. Be sure to monitor the forecast this week!
Look for several rounds of strong to severe storms this week beginning late Tuesday night into Wednesday morning, when a warm front lifts northeast across the region. However, there is uncertainty as to how far northeastward the strong/severe storms will hold together. Later on Wednesday, between the late afternoon and evening, the greatest risk for severe storms arrives with a cold frontal passage. All severe weather hazards are possible across the entire area. Finally, there is another risk for severe storms Thursday afternoon and evening, mainly focused in east-central Wisconsin. However, storm development and the severe threat will be highly dependent on how the storms evolve on Wednesday, so confidence is low in storm timing and details. Overall, make sure to stay up to date on the latest forecast and have multiple ways to receive warning information!
