There were multiple waves of precipitation that occurred with this major winter storm that lasted for more than two days.
The first wave of precipitation developed during the morning of Wednesday, April 10th where the initial band moved from southern Minnesota into west central Wisconsin by the afternoon and evening. This band of precipitation had thunder, sleet and heavy snow that produced several inches of snow across portions of west central Wisconsin. Most of the heavier precipitation tapered off, but light snow continued across portions of west central Wisconsin during the afternoon and evening of Thursday, April 11th.
In addition to the precipitation Thursday morning, the next weather element developed. This weather element was a significant increase in the wind speeds, with sustained winds of 20 to 30 mph, with gusts of 40 mph or more across a wide area of west central Wisconsin. This created areas of blowing and drifting snow. The strong winds also contributed to damage of power poles. The local electric company indicated 13 power poles were snapped in half near New Richmond, and parts of I-94, west of Eau Claire, was closed due to numerous crashes.
By Thursday afternoon, most of the heavier precipitation and thunderstorms had moved north and east of the area, with mainly light precipitation in the form of drizzle, light snow or sleet in small areas rotating northward as the main storm started to weaken and move overhead. In addition, wind speeds lessened.
The third wave of precipitation was associated with the main upper level system and changed the precipitation over to all snow by early Friday morning, April 12th. By the afternoon, most of the precipitation had ended, but residual light snow or flurries continued as the main system moved off to the east.
Snowfall totals as the storm ended ranged from 7 to 12 inches from Hudson to River Falls, eastward to Elk Mound, Chippewa Falls and Eau Claire. Lesser amounts were observed from Polk County, eastward to Rusk County. This area received between 2 to 6 inches of snow.
