NWS Issues Severe Thunderstorm Watch for 17 Wisconsin Counties

A slow-moving cold front is raising the evening risk of damaging wind gusts plus large hail before storms ease overnight.

Overview

  • The National Weather Service issued Severe Thunderstorm Watch 595, in effect until 10 PM CDT, covering 17 counties across east‑central, south‑central and southeast Wisconsin.
  • Forecasters say the prime window for stronger storms is the early evening, with the main hazards being damaging straight‑line wind gusts and large hail.
  • Much of southern Wisconsin is under a level 2 of 5 hail risk after a slight uptick in hail potential since morning.
  • The slow‑moving cold front is producing scattered showers and storms but does not signal a prolonged severe episode, and many areas should see only brief rain tonight.
  • Showers could linger overnight with lows near the upper‑50s, and decreasing clouds should bring sunnier, seasonable conditions and highs in the upper‑70s to low‑80s later in the week; residents in the watch area should monitor local alerts and plan for quick cloud‑to‑ground hazards and possible brief flooding.
