Wisconsin Storm Updates
Latest Information

Storm Update #1 - snow flying from the sky over southern and central WI atm with several trace amounts reported. Southeast WI looking at light snow up to about 6AM tomorrow morning. Mostly finished up north away from Lake Superior. Expecting 2-4" in the southeast.

8PM Wind Chills - down into the -30s across Minnesota, temps cooling quickly in northern WI. Warm spots in southern Wisconsin will fall quickly tonight. The cold front will reach the WI/IL border just after midnight

Beautiful freezing fog this morning!

5" as of 1pm

Start Times - between 3-6am in west-central WI, spreading through the rest of Wisconsin by noon. Likely a bit of dry air at first...heavy snow possible after that.

Peak out West - Our winter storm is taking shape in South Dakota. It's not very widespread right now - moreso focused with heavy snowfall kind of laying across the same areas as it translate east. This feature will pivot into Wisconsin early Sunday morning. Within that main band snow will pile up quickly.

Latest ARW Model Prediction - Snowfall of 6-10" looking more likely across central Wisconsin. Will begin tomorrow morning. Ending around 6PM in east-central WI.

Quiet now - snow moving back in - It's quiet now - for most - after another day of snow in Wisconsin. It won't last as a period of snow will move north through the state tomorrow morning bringing another inch or so. This won't be the end of it. More snow Friday night!

Snow shifting slowly east - snow w/wintry mix in spots has been much more common over portions of western, northern, and northwest WI the last 24 hours. It's starting to press more into the eastern half of the state tonight where it will be more common on Thursday.

Snow ending this morning - except in northern WI where light snow will linger into the early afternoon.

Dry slot has arrived - Impressive dry slot now almost into northern MN including NW WI, much further north than progged. Snow totals will struggle. Wrap around moves through early Sat AM. Expect an additon 1-3".

Winter Storm Update #1 - snow is overspreading the state on time. No changes to the forecast! Everyone will get a decent amount of snow with this one. Enjoy!

Cold night evolving - Temperatures at 10PM in northern WI already down into the -10 to-15° range. Overnight lows will dip close to or below -20° up there...relatively warmer in the south and east. Temps rebound nicely on Friday ahead of our next winter storm.

forecast update in progress - please check back soon for the latest information! Thanks!

Wednesday Update #1 - at 9:50AM - weak disjointed system with only isolated wintry mix in the far south thus far. Snow will develop across Wisconsin during the mid day hours. Less than 1" for most; 1-3" in the far north. Roads in good condition right now but that may change as snow develops.

Heavy snow ahead of schedule - heavy snow will pass through over the next 3-6 hours dropping a quick 1-3" of snow across northwest WI. Around one inch into northern WI and upper Michigan. Expect slippery road conditions overnight and tomorrow morning, perhaps some flurries lingering across the north.

9PM Snow Update - snow continues to spread east. Around 1-2" by morning. Slippery roads possible overnight. Wishing everyone safe travels!

Light snow moves in tonight - It will approach from the west, perhaps rather quickly later tonight. Be prepared for slippery roads overnight and possibly for the Monday morning commute.

Winter storm ending - 2-4" reported across far southeast WI. The heaviest snows are moving out. Cannot rule out light snow showers through up through midnight.

Down it goes again - Znow is moving back in across southeast WI. Models today continue to back track and lower snow amounts run after run. Rare to see such a huge downtrend. AS IT STANDS RIGHT NOW you will be lucky to get an additional 2-4". I don't believe the 8-12" Will materalize. Windy conditions continue with gusts near 35 MPH in the east (perhaps over 40 MPH along the lakeshore). -JP

Additonal Snowfall - Confidence is still low with this event and some models are further east with the snow tonight. Peak time for accumulation is between 4PM and Midnight tonight. 4-8" in portions of southeast WI.

Today/Tonight - Relatively quiet today with the peak freezing rain period done with. Cannot rule out light freezing drizzle in southern WI. Wouldn't be suprised if dry air cut that off entirely. Heavy snow develops further south into southeast WI after 4PM tonight ending around midnight. Models vary on how far west this next round will go...no farther than Oshkosh - Dubuque line is my expectation. Additional 4-8".

Road Condition Report - slippery stretches all over southern and eastern WI, ice covered on 94 between Madison and Janesville and 41 south of Fond du lac. I'm guessing light snow has compacted into black ice north of Green Bay. Roads should improve today as plow crews get after it during the warmest part of the day.
