Another snowstorm has begun to spread snow across the central Plains and Great Lakes, impacting millions.
Snow is expected to intensify throughout Sunday with the heaviest snow falling from St. Louis to Chicago, Detroit and London, Ontario. Upwards of 6 inches of snow is likely to fall across this area.
Drivers should expect slick, snow covered roads, slowing traffic and bringing a heightened risk for accidents. Additionally, gusty winds will create drifting/blowing snow that can reduce visibilities with wind gusts as high as 30 mph.
Extensive flight delays and cancelations will likely occur at airports across the region, including O'Hare International Airport in Chicago.
An icy mix will also develop across the Northeast ahead of the snow.
