Snow Starts on Sunday Night

Jan 13 2018 12:30 PM CST| 0 Comments | Wisconsin | Weather Forecasting

2-4" of fluffy dry snow expected to fall between Sunday night and Tuesday morning across Wisconsin, with higher amounts in the north and northeast.

Snow will impact Wisconsin starting Sunday night ending Monday night for most. Snow will linger into Tuesday morning in spots such as northeast Wisconsin.

A strong clipper system will move out of Canada Sunday and track square across central Wisconsin. As it passes over Lake Michigan atmospheric flow will pivot out of the northeast and keep snow flying into Tuesday morning or some.

Rather strong alberta clipper and associated upper low will swing across Wisconsin.

2-4" of snow accumulation is expected. Higher accumulations of 4-6" will be possible in northeast Wisconsin and upper Michigan. lake effect will be possible in the snow prone areas of far northern Wisconsin where 6-12" could fall, but also along the lake Michigan shoreline in northeast Wisconsin. Exactly how much lake effect snow places like Sturgeon Bay, Two Rivers, and Manitowoc get is still uncertain. It will depend on where the lake effect band sets up.

Snow will be of the fluffy, dry character with high snow-to-liquid ratios. Our forecast is a little more aggressive than typical due to snow ratios, deep and saturated snow growth zone, and long duration accumulation window (in the northeast at least). Forecast models are in above average agreement at this time.

Following the snow Monday night into Tuesday, another surge of cold air is expected but not quite as harsh as we've seen. Subzero low temperatures (single digit highs) are progged for Tuesday, looks a bit warmer in the east due to cloud cover. If clouds are slower to leave statewide, temperatures Tuesday night could stay a bit warmer. A weak warming trend appears likely late next week ahead of our next storm system.

Forecast Low temperatures Tuesday night. It may be warmer in the east due to lingering cloud cover.
