Dry Air Keeps Heavy Snow Out of Northeast Wisconsin

A storm system that moved across the Midwest and produced heavy snow in western and far southern Wisconsin produced very little snow in the northeast part of the state. The storm battled dry, Canadian air which was entrenched across northeast Wisconsin and Upper Michigan.

Surface weather map at 6:00 am CST on March 5, 2013. High pressure over southern Canada fed dry air into northeast Wisconsin. Upper air observation at Green Bay. Note the dry air about 2 km (6500 ft) above the ground.

 

Snow did make it as far north as Appleton, but accumulations in the Fox Valley were generally an inch or less. Only a few flurries fell in Green Bay.

Radar animation from 4:30 am to 7:00 pm on March 5. 48 hour snowfall map. Most of the snow in Wisconsin fell on March 5.
