The largest ever 24 hour snowfall for November occurred last weekend in Wisconsin, according to the National Weather Service. NWS reported that southern Wisconsin received 6 to 12 inches of snow over the weekend, leaving transportation limited until snowplow crews were able to clean up the roads, Dane County deputy highway commissioner Tim Pelton said.

“We worked around the clock from Saturday morning til Monday morning to make sure the roads were ready to go,” Pelton said.

Pelton said the state and county highways surrounding Madison were cleared by crews by Monday morning.

The Wisconsin Department of Transportation partnered with the county highway departments to provide maintenance and use cleanup vehicles and materials to clear up the roads as fast as possible to make transport safe again for those on the highways, according to an email statement from WisDOT.

Before the snowfall hit Saturday, drivers were advised to take precautions while traveling and if possible limit their overall travel, the county executive for Dane County said in a statement.

The snow on Sunday made it the largest snowfall ever recorded on that date, according to UW. The snowy and suboptimal road conditions will require students and commuters to drive more slowly to avoid hazardous transport, according to the county.

NWS reports that an incoming cold front and polar vortex will make the later days of this week cold for early December, making any precipitation on roads and sidewalks hazardous to pedestrians and drivers.

Pelton said that drivers should remain cautious and slow down when weather conditions become hazardous.

“We just ask that traffic reduce their speed,” Pelton said. “Give our plow trucks room to work. Our folks want to get home safe too, so reduce your speed and be prepared for changing conditions.”
