SULLIVAN, Wis. (AP) -- The National Weather Service says a tornado watch currently in effect in southwestern Wisconsin may be extended as the storms head eastward.
Meteorologist Denny VanCleve says a line of storms moved into southwest Wisconsin early Monday afternoon. He says the winds are mostly straight-line, but some are swirling in a way that could give rise to a tornado.
He says the storms are sweeping across the southern part of the state, expected to arrive in the Madison area about 5 p.m. and Milwaukee by 7 p.m.
He calls the storms a "high-moisture event" that could drop 1 to 2 inches of rain in quick cloudbursts, accompanied by thunder and lightning.
The forecast calls for things to clear up by late evening, with maybe a few light showers Tuesday.
