A tornado watch covering a large swath of Wisconsin, including Dane County, was issued Wednesday by the National Weather Service. The event that straddled Boone and McHenry counties lasted about 13 minutes, the National Weather Service says.
The storms that are passing south of our viewing area are showing high winds and heavy downpours. There will be a threat for a few tornadoes with the strongest storms as well.
Storms blew through the Chicago area Wednesday evening.
With these storms, the main threat will be damaging winds near 70 miles per hour, large hail between 1-2 inches in diameter, and a chance for some isolated tornadoes.More news: Rosenstein Briefing to Senate Suggests Russia Probe Now Criminal, Republican Senator Says

Because of the near stationary front just to the west of the broadcast area, showers and thunderstorms will continue through Saturday. That sun is key to the severe weather forecast this afternoon.
Update: May 18th @ 3:20 p.m. "[This] will be the focal point for any kind of storm activity".
Any storms that do develop are expected to end by midnight.
Thursday also looks mainly dry but chances for more widespread rain/storms will ramp up quickly Thursday night into Friday. An isolated tornado can not be ruled out especially in the more organized linear complex.
