There’s more rain in the forecast for portions of Wisconsin, in the wake of heavy precipitation overnight Thursday. The National Weather Service in Sullivan has issued a flash flood watch for 7:00 p.m. Friday to 7:00 a.m. Saturday, with south-central Wisconsin expected to see an inch or more of rain in areas which experienced 2 to 3 inches overnight Thursday into Friday.
Counties covered by the watch include Dane, Green, Lafayette, Rock, Jefferson, Kenosha, Milwaukee, Racine, Walworth and Waukesha.
“A cold front sagging through southern Wisconsin will stall in the vicinity of the Illinois/Wisconsin border today,” according to the NWS. “Showers and thunderstorms will redevelop this afternoon as surface low pressure lifts northeast from northern Missouri along the boundary across northern Illinois this afternoon and evening, moving to Lake Huron by Saturday morning. Totals of an inch to 1.3 inches are possible.”
“Saturated soils will be less able to absorb this next round of heavy rain,” the statement issued early on Friday warned. “The resulting runoff could wash across roadways and flood underpasses, low-lying areas as well as small rivers and streams.”
