Possible Severe Storms Expected Overnight and Thursday: First Alert

Storms Forecast for Southeastern Wisconsin on Tuesday

The city of Rockford, Illinois experienced a significant change in weather on Wednesday as the heat made a comeback following four consecutive days of below-normal temperatures.

On Wednesday, the Chicago-Rockford International Airport recorded a scorching high temperature of 92°, marking the hottest day of the year in 2024 thus far. However, this record is expected to be short-lived, as the weather forecast indicates that we can anticipate continued hot and humid conditions in the near future.

Regrettably, this could result in several episodes of showers and thunderstorms, with the possibility of severe weather within the next 24 hours. Showers and thunderstorms have already been forming in the northern and central parts of Minnesota on Wednesday evening, and according to model predictions, they are likely to persist throughout the night and may even reach the Stateline after midnight. These storms will move rapidly and may produce extremely heavy rainfall and strong gusts of wind, but they should weaken enough that we do not anticipate a widespread threat of severe weather.

With plenty of sunshine expected on Thursday, temperatures are set to rise once again into the 90s.

Regrettably, this will create ideal conditions for the formation of fresh storms during the latter part of the afternoon or the initial hours of Thursday evening. The intensity of the upcoming set of storms will depend on the amount of sunlight we receive. An increased amount of sunshine will generate additional energy and result in a greater likelihood of severe weather. Conversely, a lower amount of sunshine will significantly reduce the threat of severe weather.

Over the past 24 hours, the risk of severe storms has increased. The Storm Prediction Center has categorized southern Wisconsin as a Level 1, meaning there is a marginal risk for severe storms. Meanwhile, all of northern Illinois has been classified as a Level 2, indicating a slight risk of severe weather. However, some areas in Illinois, such as Carroll and Lee Counties, have been upgraded to a Level 3, with an enhanced risk for severe weather. Tornadoes are not expected, but there is a significant risk of strong winds and potentially large hail.

Expect a pleasant change in weather on Friday and Saturday, with much quieter, cooler, and less humid conditions. Friday will be a sunny day, while some clouds will start to move in on Saturday. High temperatures for both days will be in the mid-80s.

Expect a surge in heat and humidity starting on Sunday, with temperatures soaring into the 90s each day until at least next Saturday, including Father’s Day. This also means that the daily chances of thunderstorms will make a comeback, and some of them could potentially be stronger. So, be prepared for some intense weather in the upcoming days.
