Heavy Rain A Major Concern Overnight…UPDATED

***Stay with WISN 12 & Weather Watch 12 for the latest weather updates!***



SE Wisconsin spared from the heavy rain. We were very fortunate with the heavy rain staying south and north of us. SW Wisconsin had over 4″ of rain last night.

Rockville in Grant County had 5.54″ of rain, while Darlington in Lafayette County had 3.90″ of rain.  In Milwaukee, no rain is good news, but Mitchell Airport picked up ‘only’ 0.79″ and Kenosha saw 1.05″.  Just south into Illinois Chicago was slammed.  O’Hare airport picked up 6.17″ of rain in the last 24 hours!

Most of Saturday now looks dry with just a slight chance of showers off and on today with a few glimpses of sunshine. Have a great day.



Thank you for stopping by the Weather Watch 12 blog. Early Friday evening I did a quick blog update and mentioned the threat for heavy rain.

Thunderstorms producing torrential rain developed over Iowa and Illinois around 9:30 p.m. Friday evening, and headed directly into southern Wisconsin. More flash flooding is expected overnight as a band of thunderstorms will once again set up, and move over the same locations.

Early Friday evening I was thinking the heaviest rain may stall near the Wisconsin and Illinois border, keeping most of our area in a general 1 to possibly 2 inch rain band. As I discussed on WISN 12 News at 10pm, that band of heavy rain now looks like it will set up over southeast Wisconsin, and possibly right over the same areas that were hardest hit on Thursday.

Rainfall totals of 2 to 4 inches plus may be possible overnight in isolated spots, with general rain bands of 1 to 2 inches possible. Below is a forecast of rain amounts from our in-house computer model. The fact that this model, along with one other points to the heaviest rain over southern Wisconsin has me worried that major flooding could once again occur.

Below is the rainfall forecast map through Saturday. Most of this rain will fall in the span of about 4-6 hours!  Keep in mind this band will likely shift a little bit from what the model is suggesting.

We will keep you updated all night and day on WISN 12! Please send along your rain totals, and remember, do not drive into flooded roads! You never know how deep the water may be!

Remember you can track the storms at home with our interactive radar.


Look for more blog updates throughout Saturday!

  1. It is 6:48 A.M. Saturday morning. Up in NE Dodge County the rain has stopped, the sky is beginning to clear, and I can notice a definite change in how the air feels…cooler and less humid. There is a nice cool breeze beginning to come in through the north windows. Is this the end of the rain? I hope so.

    I got up several times during the night to check the basement…fortunately no water, so I’m hoping we made it through. Keep your chin up Milwaukee, the cooler, drier air is on the way.

    • Cliff,

      Most rain totals were in the 0.50″ to 1.50″ range, certainly glad we missed the 3-4 inch totals. Those stayed in SW WI. Jeremy

  2. By the sounds of the WGN Chicago blogs this morning, it looks like many areas down there got the 4-8 inches this time around. I can’t even imagine the disaster we’d be facing if the storm track would have been over us again.

    • Daniel…Chicago O’Hare airport picked up 6.17″ of rain in the past 24 hours! Jeremy

  3. 1.23 inches in Sheboygan this morning.

    • Thanks Robert! Basically a few sprinkles compared to recent rains! Jeremy
