ROCKFORD (WREX) — A couple chances for showers and storms will develop as the warm and humid weather comes to an end. Heavy rainfall may be a threat with any storms that build up.
A cold front will push southward toward the Stateline out of Wisconsin tonight. Scattered showers and storms may develop ahead of the front, providing some pockets of soaking rainfall locally. Storms should pop up after 7 pm, then linger under around midnight. After that, the front looks to slowly move back north again, and push rain out of the area for the rest of the night.
We’ll have another warm and stuffy night on our hands. Temperatures will remain in the upper 60’s, with high humidity.
After a quiet morning, Thursday afternoon looks to be active again. Scattered showers and storms are possible, and these storms could produce some heavy rainfall or isolated severe weather. We have a slight risk for severe storms tomorrow, mainly west of I-39. Strong winds and hail would be the main threats. A slight risk for flash flooding is possible as well. Since the air is so humid, there’s a lot of moisture that can be wrung out of the air. This can lead to flash flooding if storms move slowly.
The scattered activity will wind down in the evening, then one final round of storms moves in closer to midnight. This looks to be a long line of storms, so all areas will get at least some storm activity. The line sets up along a strong cold front, which will get rid of the heat and humidity for a couple of days. Watch out for torrential rainfall and strong winds as this line of storms comes through.
Once the front sweeps past, we’ll have cooler and much less humid air in place for Friday and Saturday. Temperatures will be back down into the 70’s. By the end of the weekend and the start of next week, however, low 80’s are back, along with higher humidity. There’s a chance for rain again early Sunday morning.
