Wisconsin Weather

MAR 18, 2020 | Wednesday Rain/Snow

1:25PM TUES - Models today shifted the best chance for snow much further south, into southern WI. EC/NAM bring 1-2" to southwest WI. Kind of a big jump from yesterday so will expand the 0-1" across all of WI but not everyone will see snow. Added a target zone if for southern WI.

10:25PM MON - no changes based on latest info. Next update by late AM Tues.

8:00AM MON - A precipitation shield will cross through Wisconsin during the day Wednesday bringing some rain to the south. Models generally show 0.5-0.9" amounts south of a Richland Center to Menomonee Falls line. EC is a little wetter than GFS with heaviest amounts in northern IL (close proximity). NAM appears too wet. I've taken the conservation GFS route for now which seems to compliment WI as a whole. 0.1-0.5" north of that line with possibly a light rain/snow mix. Minor snow accumulations at best. Light minor stuff.

This will be a low impact storm event. Isolated/scattered rain showers may continue into Thursday ahead of the next storm system.

Snow likely overnight - latest models showing up to an inch or so in portions of central or even southern WI into early tomorrow AM. Could be similar to the light snow we saw earlier this week. Little to nothing across northern WI (away from the snow belt).
3:30PM Regional Update - the most active day we've had across the region in awhile. Severe thunderstorms possible across Iowa as storms currently in Nebraska shift east tonight. Still think it will be a near miss for Wisconsin on the strong/severe threat. Will keep an eye on far southern WI tonight anyway. For WI overall it's really the snow/rain activity coming from the west that will slide through tonight. An additional inch or two of snow could fall as far south as southern WI by early Friday morning.
T-storms approaching - Will be working through over the next few hours. Severe weather not expected with this round however cannot rule out small hail.
Rain arrives mid-day - Good Morning! Rain & storms will arrive during the mid-day hours and hang with us throughout the evening. Broken line of tstorms currently moving into Iowa. We're next in line.
Snow/Rain this morning - Snowing pretty good in spots around southern WI. 2.2" in Oshkosh so thinking about up to 3" based on that one single report I have. This morning snow will gradually end or turn to rain as the system slides east.
