TONIGHT - T-storms in northern Iowa were quick to produce 2" of rainfall accumulation this evening. This activity will move north across Wisconsin tonight. Just the first of several rounds of rain this weekend.
SAT/SUN - Models still disagree on exactly where the heaviest rain will fall. All suggest 2-4" somewhere in Wisconsin by early Monday AM. I've continued to blend models together to create the 2-4" zone and will not adjust any further. I don't know exactly where those 4" amounts will end up. I'm skeptical of the models putting the heaviest rains over the northwest. I suspect convection will keep the heaviest rain across central or southern WI. Just not sure. Challenging forecast.
With so much rain and clouds we likely won't see much t-storm threat this weekend. Will handle anything that develops on a short term basis.
