FORECAST DISCUSSION

As of 2:30 p.m. the first line of storms was halfway through the NBC15 viewing area. Thunderstorms hit severe limits over Lafayette & Green counties with winds around 60 mph. Gusty winds were noted up and down the line, but remained sub-severe. That line is expected to cross through Milwaukee around 3:30 p.m. - hours before the NBA Finals Game at Fiserv Forum.

Meantime, gusty & moisture-rich southerly winds aloft were creating an environment conducive for storm redevelopment. A remnant boundary from earlier storms in Minnesota will be the focus for these later storms. High-resolution models show storms firing around 6-7 p.m. and dropping SE through the NBC15 viewing area.

The Storm Prediction Center (SPC) has issued a Tornado WATCH for much of eastern Iowa. We’ll be monitoring to see if that watch is extended into our area. Storms should drop to the State Line and fester in Illinois early Thursday morning. At that point, the severe threat will come to a close.

By Friday, high pressure will build in from the north and bring quiet and comfortable conditions for Friday. Lots of sunshine is expected through the weekend with highs back in the 80s.

Today: Increasing cloudiness with showers/t-storms likely. High 85. Wind: North 5 mph.

Tonight: Showers and t-storms likely. Some could be severe. Low: 68. Wind: Bec. Southwest 5-10 mph.

Thursday: Mostly cloudy with rain likely. High: 75.

Friday: Mostly sunny. High: 79.
