A big snowfall event is forecast starting today and into the weekend. The featured map is the NWS National Digital Forecast Database (NDFD) accumulated snowfall until Monday evening. Much of Iowa is painted in the 6 to 12 inch range. There will also be strong winds and bitter cold temperatures making for a strong reminder that we are still in the middle of the winter season. The map also shows the significant amounts of snow expected over the northeastern US with a foot or more forecast over a very large area.
