Early Friday Update: Severe storms are done but scattered storms continue
Updated: 4:05 a.m. Sep. 4, 2026
We are currently severe warning free across southeast Wisconsin. The last warning ended at 3:30 a.m. As of 4 a.m. none of the storms are showing any sign of being strong or severe. Any additional rainfall could increase flooding concerns with parts of southeast Wisconsin that have picked up 1-5" of rain with the storms since 10 p.m. Thursday night.
There are still plenty of downpours and isolated storms out there across the state even in central and northern Wisconsin and most of those storms are moving towards our area. The chance for storms will continue most of Friday morning but by the afternoon it looks to dry out. A few more isolated storms may be possible Friday evening, but widespread severe weather is not expected.
Here is a radar image that will update with time:

Severe weather continues into the early morning hours of Friday. We have seen consistent severe thunderstorm warnings for about four hours now as the first warning came in for Dodge County just before 10:30 AM Thursday night. At times the risks have been more hail and at other times strong wind. Thankfully, none of the storms have shown much in terms of rotation indicating any tornado potential.
We are currently just watching one storm right now that is moving into Fond du Lac County. Earlier as the storm moved into the Oshkosh area it was showing some very strong signs of damaging wind with 70 mph winds or stronger possible. Now it has started to lose some of that intense shape, but could still have wind gusts to 60 mph associated with it and hail about 1" size in diameter.
A severe thunderstorm warning is currently in effect for most of Fond du Lac County until 3 AM and a newly issued severe thunderstorm warning is in effect for parts of Sheboygan, NE Dodge, Washington and all of Ozaukee Counties until 3:30 AM.
The rest of southeast Wisconsin has seen some pop up downpours and storms, but nothing too severe. So far, most of our southern counties have stayed dry and away from any severe storms.
Here is a radar image that will update with time:
In addition to the severe storms, we are also becoming concerned about the potential for heavy rain and flooding. A few Flood Advisories have been issued for parts of southeast Wisconsin as some of the heavy storms roll through. Parts of Dodge and Washington Counties picked up 1-3" of rain with the severe storms Thursday night. These are some of the same areas that also saw 1-3" of rain with heavy storms Thursday morning so the ground is quite water logged in these areas. As this next round of severe storms moves into these counties we could likely see a Flash Flood Warning issued and many wet basements could become an issue.
If this latest severe storm continues on its path it would be in the Milwaukee metro after 4 AM Friday and continue southeast from there eventually moving over Lake Michigan.

Updates 12:05 AM Sept. 4, 2026
It's been a hurry up and wait game for the storms, but now they're making their way into our viewing area. We have a few Severe Thunderstorm Warnings in place for the next hour mainly just north and west of the Milwaukee metro. Large hail, up to baseball size, is the biggest threat along with wind gusts around 60-70 mph. There's also a Flood Advisory for the next few hours for portions of Fond du Lac, Dodge, and Washington Counties. Several inches of rain have fallen and several more inches are possible over the course of the next few hours. Watch for water-covered roads and be prepared to move to higher ground. Stay tuned to CBS 58 on air and online for the latest weather updates.

There is a strong line of storms that is moving southeast at 40 mph. This could contain some small hail and gusty winds to 40 mph. It will move into Fond du Lac county after 9:30 pm.
The computer models differ on timing and placement of showers and storms overnight; however, they look to be consistent in bringing a line of showers and storms through the area by Friday morning.
A severe weather risk remains overnight with wind and small hail being the primary threats. Locally heavy rainfall could also be a factor, so localized flooding could occur especially in areas that saw a few inches of rainfall this morning.
Best chance for rain and storms for Friday would be during the morning.

The first round of rain and storms has passed by, and that has left a worked over atmosphere for the time being. Take a look at the picture above.
This is from the meso analysis page from the SPC. The blue shaded area is representative of an atmosphere that's been worked over by showers and storms. South of our area, CAPE values have spiked with high heat and humidity.
Right now, the newest model runs aren't very bullish on developing another strong to severe batch of storms this late afternoon or evening. We will need to keep an eye on things, but it looks like a better chance for more rain will come overnight into Friday morning.
Here are some of the rainfall totals from earlier today!
__________________________________________________________________________________________________________
The alerts have expired and heavy widespread rain is over for now. You can see the corridor of heaviest rainfall where possibly 2-3" fell.
We had isolated trees down reports around Horicon and Richfield areas, but now we have only isolated cells producing just moderate pockets of rain. We still anticipate some sun with highs around 80 this afternoon before round of storms return around midnight to around sunrise on Friday. Updated: 10:27 a.m. Sep. 3, 2026
Heavy rain has been falling with many of the strong to severe storms this morning. A flash flood warning has been issued for parts of northern Milwaukee/Waukesha Counties and southern Washington/Ozaukee Counties. These areas have seen 1-2" of rainfall with the severe storms. Another 1-2" of rain is possible with more storms this morning. The Flash Flood Warning goes until 12:15 PM.
As of 10:30 a.m., most of the storms are showing no signs of being strong or severe. Even the heavy rain potential has decreased. The heaviest storms are currently in Rock and Walworth Counties and moving east. These could bring heavy rain causing briefing flooding and lots of lightning.
Here is a radar image that will update with time:
We are still on track for a relatively dry Thursday afternoon before more storms develop after sunset Thursday evening through Friday morning. Flooding is becoming the biggest threat with any severe storms we get Thursday evening. But tornadoes, wind and hail are all also possible.

Strong to severe storms are currently moving through southeast Wisconsin. So far, these storms have mainly stayed north of I-94 but will likely drift a bit south over the next few hours. One of the storms really strengthened as it moved in southern Washington County and sparked a severe thunderstorm warning until 8:45 a.m.
More strong to severe storms will be possible through the rest of the morning with more severe thunderstorm warnings possible. Most of the afternoon hours are still look dry and then the chance for a few rounds of strong to severe storms are still on track to move in after sunset Thursday evening through Friday morning.

Scattered showers and storms are likely on Thursday. A few of those storms may be possible during the morning and afternoon hours, but the better chance for rain overall is in the late evening and overnight through Friday morning.
The storms that do form late Thursday through Friday morning could be on the strong to severe side. Most of southeast Wisconsin is included in the Level 2 Slight risk for severe weather.
Strong wind and some hail will be the main threats with any strong storms that do develop Thursday night. An isolated tornado or two cannot be completely ruled out and some brief flooding may also happen as rain falls quickly and heavy with the storms.
High temperatures on Thursday won't be as hot as they were Wednesday when Milwaukee got into the 90s for the first time since the middle of July, but they will still be humid. Dew points will be similar to where they've landed most of this week in the low to middle 70s making it feel fairly tropical outside. Humidity will stay high through Saturday then start to drop for the start of next week.
