Feb 28-29 Winter Storm Summary

Winter Storm of February 28th-29th, 2012

Snow Totals Rain Totals

A winter storm drove eastward across the Upper Mississippi River Valley from Tuesday night (Feb 28th) through Wednesday afternoon (Feb 29th). Due to a abidance of relatively warm low level air ahead of the storm, there was a variety of precipitation types that fell. Heavy snows fell across central Minnesota and northern Wisconsin, with foot totals fairly common. South of there, a snow, sleet, rain and even some freezing rain all fell from time to time. Rain was the dominant precipitation  type for much of Tuesday night from Highway 10 in north central WI to Interstate 90. Snow totals were much less in this region as a result, but icy spots did develop on less traveled roads and those along bluff tops. Then south interstate 90 it was all rain with an added rumble or two of thunder Tuesday night. As the storm exited east Wednesday, light snow spread back across the region but additional accumulations were minimal.

Observed weather from the storm included:

  • 10-17" of snow along and north of Highway 29 in Wisconsin (between Eau Claire and Wausau)
  • 2-4" of slushy snow with some sleet, rain and freezing rain north of Interstate 90. Icing on secondary roads / ridge tops
  • Rain and freezing rain near Interstate 90 with light icing reported. Rainfall totals 1.00" to 1.70", highest in southeast Minnesota
  • Smaller creeks and tributaries rising quickly
