No chance of rain until the second half of the weekend
It's been a rather dry start to September with only a couple of very light showers earlier this week.
We haven't had a good downpour in nearly a week and a half, but that'll change by the second half of the weekend. High pressure will keep us dry today and Friday, but by later Saturday evening-night showers will start to move back into southeast WI.
The low pressure system responsible for the rain will sit and spin over the area Sunday and Monday, slowly pushing east on Tuesday. This will keep off and on rain in the area most of Sunday and Monday.
There's some uncertainty where exactly this low will stall given that it'll be cut off from the main jet stream, but at this point southwest to south central WI has the best chance at 1-3" of rain through Monday. .50-1.50" of rain looks like a good bet across southeast Wisconsin.
September rainfall has been pretty all or nothing for the last few years. On average, Milwaukee should pick up a little over 3" of rain throughout the month, but you may remember how relentless the rain was back in 2018 and 2019 after barely picking up any rain in 2017.
