A blast of winter weather is set to bring snowfall and subfreezing wind chills across the Midwest and East Coast as well as near freezing temperatures in parts of the South, including in normally warm Florida. The National Weather Service said Saturday below average temperatures were being forecast for the Central and Eastern U.S. this weekend into early next week. The weather service says that in northeastern Ohio, a snow squall, sudden bursts of heavy snow and gusty winds, was creating whiteout conditions. In Tallahassee, Florida, and parts of central Georgia, residents might see some snowfall on Sunday morning.
