Besides the dangerous wind chills, many areas saw reduced visibility and ground blizzard conditions as snow on the surface was blown into the area from the northwest winds.
More winds are forecast to push into the region on Monday with gusts up to 45mph in some locations. This will create areas of blowing snow and bone-chilling wind chills once again.
