CHICAGOLAND DETAILS …
Radar is clear in northern Illinois, but lightning visible in the north sky horizon of Arlington Heights was visible from storms passing west to east near Milwaukee around 9:00 p.m. to 10:00 p.m., as indicated on radar.
As an area of thunderstorms currently developing across Iowa, Minnesota, and Wisconsin eventually approaches Chicagoland, the area of convection will be in a weakening/decaying mode by daybreak; however, an outflow boundary may push into the
area after 1-3 a.m. that could bring an isolated thunderstorm or widely-scattered showers generally along/north of the I-88 corridor, especially by late morning.
Otherwise, thunderstorm chances return Thursday, with the potential for localized heavy rainfall Thursday afternoon and evening.
The strongest storms may also be capable of localized gusty winds, mainly south of I-80.
Mainly dry, warmer weather is expected this weekend into early next week.
