Winter has returned! Accumulating snow is expected this evening through tonight as an upper level disturbance and an area of low pressure moving through the Plains interact to give us our first significant snowfall since November. Starting at 4pm this Friday afternoon, light to moderate snowfall will move into SE Wisconsin and continue overnight.

TONIGHT: Windy with snow. Accumulation: 2-5”

Low: 20

  • Wind: NE 15-25 mph

Snow will continue into Saturday morning along with gusty winds at times, which will lead to blowing snow and reduced visibility

SATURDAY: Windy with scattered snow showers. Accumulation: 1-2”

High: 24 NE 15-25 mph Gusts: 30 mph

By Saturday afternoon, snow will taper off from west to east but there will be a few lake effect snow bands lingering into the evening hours, potentially leading to higher snow totals near the Lake.

  • Friday afternoon snow begins 4pm
  • Friday night snow/blowing snow continues
  • Friday 8pm- Sat.6am Heavy bursts of snow will be possible at times.
  • Saturday morning light to moderate snow with up to an additional 2” of accumulation. 2”+ can be expected along the Lakefront.
  • Saturday evening snow end inland; scattered snow still possible along the Lake.

Impacts

Heading into Monday, we’ll be tracking another storm system which will likely bring another round of measurable snowfall into SE Wisconsin starting Monday evening and continuing into Tuesday.
