Scattered storms will remain possible for the rest of this evening, with strongest storms producing gusty winds and heavy rainfall. Highest coverage across the Stateline will be primarily South of Rockford. Coverage will begin to decrease near 8PM as the sun begins to set.

Another wave of steady rain showers and thunderstorms may be possible toward midnight. These would largely bring a risk for heavy rainfall, with only a few embedded rumbles of thunder.

Highest chance for severe weather this evening is across Iowa and Southern Minnesota, but the Stateline remains under a Level 1/5 Marginal risk from the Storm Prediction Center, primarily for a damaging wind risk. The hail and tornado threats are much lower locally.
