A bulky storm that will eventually stretch to the Northeast with disruptive snow and ice has already caused havoc in the Tennessee Valley and as far west as the Rockies.
The path of the storm will encompass nearly 2,000 miles, unleashing rain, snow and ice over the weekend.
Travel reaching from Denver to Nashville and northward as Boston could be treacherous as roads become slick. Numerous accidents were reported midday Friday across Tennessee and Mississippi due to icy roads.
"The storm will blossom and expand tonight, exploding across a large statewide area instead of affecting smaller, localized regions," AccuWeather.com Meteorologist Dave Samuhel said. "Snow will spread and become heavy across the Ohio Valley with ice in the Tennessee Valley tonight before reaching into the Appalachians by dawn."
