Rainfall during the month of June started off a little slower than some would have liked. After coming off of a fairly wet and cool spring it was nice to dry out but it was starting to get a little too dry; until last Friday night. Thunderstorms pounded the Midwest with significant rain falling over parts of Wisconsin and Northern Illinois late last Friday and early Saturday morning. In fact, Rockford set a daily rainfall record last Saturday when over 2 inches of rain fell. Additional showers and thunderstorms in the days to follow really added up with continuous thunderstorms through Thursday evening. So far 6.89" of rain has fallen in June putting us nearly two and a half inches above the monthly average. What's even more impressive is a little more than five and a half inches of that rain fell within a week! A few thunderstorms did develop Thursday afternoon with torrential downpours but most of that fell east and northeast of the Stateline.
Additional showers/storms are likely again today and Saturday as a few upper level disturbances move through. The image on the left is the future radar at 3pm from the HRRR model and it shows those showers and thunderstorms popping up with the heating of the day and drifting to the south and southeast. I believe showers will begin to develop around noon to the north in Wisconsin and move into northern Illinois between 1pm and 3pm. While severe weather isn't anticipated some of the heavier showers/storms could contain small hail and brief heavy downpours. Rainfall amounts over the next couple of days should remain under an inch so any additional river flooding is not anticipated.
