The major snowstorm that is headed to the eastern Great Lakes and Northeast has commenced across the southern Plains, creating a white Christmas and nightmares for travelers.

Freezing drizzle earlier this morning led to a series of about 10 collisions on Interstate 40, near I-35, at about 2:50 a.m. CST, according to KOCO.

The accident involved 21 vehicles, three of which were semi-trucks. At least 12 people sustained injuries, but none were considered extremely serious.

The freezing drizzle in Oklahoma City will transition to the snow that is spreading eastward from western Kansas and the Texas Panhandle. The snow will even reach Dallas and western Arkansas before the day is over.

Little Rock will turn into a winter wonderland tonight as a blizzard unfolds to the north across southeastern Missouri and southern Illinois. On Wednesday, the snowstorm will take aim at the eastern Great Lakes and Northeast.
