Although it will be a fast-moving system, traversing over 1,800 miles in 72 hours, it will still produce notable snowfall across more than a half a dozen states.
Widespread snowfall accumulations of at least 6 inches are expected from northern New Mexico to the Upper Peninsula of Michigan.
Heavy snow and strong winds will create blizzard conditions Sunday as the storm exits Arizona and heads to the Texas and Oklahoma panhandle region Sunday night. Blizzard warnings were already hoisted in Colorado and New Mexico early Sunday morning.
Poor visibility and difficult-to-near-impossible driving conditions will set in for the Southwest on Sunday, the central and southern Plains on Monday and the Midwest on Tuesday.
Strong winds will also bring wind chill values below zero degrees for some locations in the Plains.
Snow and cold temperatures will not be the only concerns as the storm surges northeast
, intensifies and expands its reach to much of the eastern half of the US into the middle of the week.
Flooding, damaging winds and even tornadoes will also be concerns.
Along the Gulf Coast, warm, moist air will fuel the threat for severe storms, including a few strong tornadoes and damaging winds.
