A soggy end to the work week is expected with chances for rain continuing on and off through Saturday night. Heavy rainfall will be possible, especially for areas across Northeast Iowa and Southwest Wisconsin, where repeated rain chances are highest. Temperatures will be near to slightly below normal in the 70s to lower 80s.
A stalled surface front across central Iowa into northern Illinois will spark showers and storms tonight into Friday bringing the potential for heavy rainfall to the region. While the heaviest rainfall will very likely remain to our south (80+%), there is some potential for this rain to move northward into northeast Iowa and far southwest Wisconsin (<20%). Localized flooding and river rises would be expected in this lower potential scenario.
