A strong winter storm will bring severe and wintry weather across much of the country through Monday.

The storm swept across the mid-Mississippi Valley on Sunday afternoon and moved toward the mid-Atlantic on Monday. The resulting snow, ice and even severe storms will cause major chaos across much of the eastern third of the country.

Winter weather warnings will be posted along the storm’s path.

Along the East Coast they extend as far north as Ocean County, where a winter weather advisory is in effect Monday for 2 to 4 inches of snow. The storm is expected to move too far south of the Tri-State area to significantly impact the New York City metropolitan area.

Up to 10 inches of snow is possible in a narrow strip from Kentucky and Ohio through West Virginia to Virginia and Maryland. Washington, DC and Baltimore are expected to be hardest hit.

From city streets to highways, land transportation will come to a standstill. In the air, extensive delays and cancellations are to be expected due to the storm.

This will be a major headache for Tri-State travelers. If you’re planning on heading south into South Jersey or via the I-95 corridor through DC on Monday, think twice.

If you fly on Sundays or Mondays, watch for airline warnings about delayed or canceled flights. If you have the option to rebook for a later date, you should consider doing so.

Road traffic in the tri-state area will be much better. The city and central Jersey may experience severe weather or light snow Monday from mid-morning to mid-afternoon, but only a dust cloud of less than an inch will accumulate.

At temperatures below freezing, anything that accumulates will stick. Some roads may become slippery in places. Therefore, drive slowly and allow extra time to get to your destination. Otherwise, local traffic will not be significantly affected.

Gov. Phil Murphy declared a state of emergency for much of central and southern New Jersey effective Sunday at 10 p.m. due to expected winter weather conditions.

In addition to the snow, freezing rain along the storm’s path will create treacherous driving conditions for millions of people from Missouri to Virginia.

Further south, severe storms could produce straight-line wind and/or hail-damaging tornadoes in Louisiana, Arkansas, Mississippi and Alabama on Sunday night, expanding into Georgia, northern Florida and South Carolina on Monday.

The storm will move offshore late Monday, but with the cold air staying in place, the remaining winter blanket isn’t going anywhere anytime soon.
