The storm did not end until dawn in most areas. Here are the latest images on our radar:
Lingering activity will continue to drift northward.
Updated: Friday, June 21, 6:10 p.m.
We haven't had any warnings since before 5pm tonight, which is a good sign. The storm is still continuing but is moving slowly north of the I-94 corridor. I hope the outdoors in Milwaukee stay dry tonight. At least until after midnight. Meanwhile, other weather events occurred at summer festival venues. check it out:
The camera's perspective points toward Summer Day and you can't see anything because the fog is billowing in the lake breeze. As you can see, it also provides a cooler in the subway. This is good news. Take a look at our internal model at 8pm:
The activity you see here is just north of I-94 and will continue to move north before dissipating around 10 p.m. Severe weather will be significantly reduced tonight. But rounds of rain and storms are expected until 3am on Saturday. This will continue until about noon. Then, as the cold front approaches northwest cities like Fond du Lac around 5 PM, we could be in for a clean break with the final round and the best chance of severe weather. This will probably hit the subway around 7pm and should be over by 9pm. Then we save the weekend with a great Sunday.

By this time the storm had reached its severe limit. Here is the latest information on alerts:
This Warner group worked in southwestern Dodge County and northwestern Jefferson County, working only eastward at about 20 mph. Here are some locations from this storm. Of concern are wind gusts of 60 mph and quarter-sized hail. We continue to monitor other storms, which currently remain under strict restrictions. However, some storms may contain lightning, and in most storms heavy downpours are possible. Storms are likely to continue throughout southeastern Wisconsin through the night. Please follow CBS58 for ongoing updates. Additionally, intermittent rain and storms will remain with us through Saturday night. Anywhere with recurring storms overhead, rainfall amounts in excess of two inches are possible. Milwaukee County is not officially included in the watch, but storms are still expected to be possible tonight and tomorrow.
Updated Friday, June 21, 1:45 p.m.:
Scattered thunderstorms are beginning to develop near the front line in southwestern Wisconsin. These storms have produced very heavy rainfall and will continue to intensify as they move eastward through the afternoon.
It is worth noting that there is a lake breeze, which keeps the temperature and dew point lower near the lake. That being said, there remains a Level 1 “marginal risk” for southeastern Wisconsin tonight due to damaging winds.

Updated Friday, June 21, 11:30 a.m.:
All eyes are on the stationary front to our south, slowly but surely rising northward this morning. As of 11 a.m., the front had moved farther into southwestern Wisconsin and was located along the Illinois border. The front is moving north more slowly than expected, so it will only reach the I-94 corridor at most.
Where this warm front ends will be the focus of thunderstorm training between 3 and 10 p.m. Storms can be strong to severe at times, with damaging winds and the potential for flash flooding being major concerns.
If this front continues its slow northward trend, flood warnings may be extended southwards early this afternoon.

A few showers are developing Friday morning, but no thunderstorms yet. The risk of thunderstorms will not begin to increase until after 3pm on Friday.
Here are the radar images updated over time:
There is a threat of heavy rain both Friday and Saturday. Flood warnings have been issued for several Wisconsin counties, including locally Fond du Lac, Dodge, Washington, Jefferson and Waukesha counties. Severe storms and storms hitting the same area multiple times could increase rainfall totals to more than 2 inches at these locations.
The remaining severe risks and storm chances listed below are on track.

Rain chances will increase as the weekend begins. After a mostly dry start Friday, showers and storms return Friday afternoon and evening. The best chance is after 3pm on Friday.
Some storms developing Friday afternoon and evening may become stronger. All of southeastern Wisconsin is under a Level 1 marginal risk for severe weather, while areas on and west of the western edges of Fond du Lac, Dodge and Jefferson counties are under a Level 2 minor risk.
Better storm chances will be Saturday, with scattered storms possible throughout the day from morning to noon, afternoon and evening. The best chance for strong to severe storms may occur Saturday night along the line of cold fronts and storms.
Once again, strong to severe storms are possible, with a greater chance of severe storms on Saturday than Friday. Inland and western counties are at Level 2 mild risk, and counties near the lake are at Level 1 marginal risk.
The main threats on Friday and Saturday will be wind and flooding. Significant rainfall is possible, causing flash flooding, ponding on roads and minor street flooding. There is also the possibility of some hail or isolated tornadoes over these two days.
Rainfall totals from Friday to Saturday will range from 0.50 to 1.50 inches across much of southeastern Wisconsin, but some areas are sure to see 2-3 inches of rain and storms. Fond du Lac, Dodge, Washington, Jefferson and Waukesha counties have been placed under a flood watch from Friday afternoon into Saturday night due to the expected heavy rain.
