Much of Minnesota will have snow Sunday night and Monday. The Twin Cities metro area, south-central and southeastern Minnesota plus parts of west-central Wisconsin could see snow continue into Sunday evening, then a rain/snow mix or rain later Sunday night, followed by mainly rain on Monday.

URGENT - WINTER WEATHER MESSAGE National Weather Service Twin Cities/Chanhassen MN 327 PM CDT Sat Mar 23 2024 ...WINTER STORM ARRIVES SUNDAY BRINGING HEAVY WET SNOW AND STRONG WIND... .Light snow will develop tonight, but the main storm system will arrive on Sunday. A heavy band of snow will develop across northern Iowa Sunday morning, and lift up from the south. Snowfall rates of 1 inch per hour are likely, with 2 inches per hour possible. Winds will be out of the east at 25 to 35 mph, which will lead to very low visibility. Snow will become more widespread throughout the day on Sunday. A Winter Storm Warning is now in effect for areas along and north a line extending from New Ulm to Red Wing in Minnesota and all of west-central Wisconsin. A Winter Weather Advisory is in place for Sunday for Mankato and the I-90 corridor. On Sunday night, warmer air will cause snow to change over to rain across southern Minnesota, and this warm air will expand on Monday. Areas in eastern Minnesota and western Wisconsin could also change over to rain. Areas in western Minnesota will likely remain all snow. There is uncertainty on where the rain, snow line will set up. On Monday night and Tuesday, colder air will move in causing a change over back to snow across much of the region. A couple more inches of accumulation is possible, but the main concern is for strong northwest winds of 30 to 40 mph to cause blowing snow across western Minnesota. The system will exit on Tuesday.
