A blast of winter weather has brought snowfall and subfreezing wind chills across the Midwest and East Coast as well as near-freezing temperatures in parts of the South, including Florida.

More snow is on the way for New Jersey on Sunday with 15 counties under weather advisories for 1 to 4 inches of additional snowfall.

The National Weather Service issued an updated snow squall warning at 12:54 p.m. on Saturday in effect until 1:30 p.m. for Crawford and Erie counties.

Avoid or delay travel: If a snow squall warning is issued for your vicinity, it's advisable to postpone or refrain from motor travel until the squall has passed through your area. Highways and roads are particularly hazardous during snow squalls.

The second of two snowstorms this weekend has led to winter weather advisories for much of New Jersey starting at 6 a.m. Sunday.

Around 55 million people across the eastern half of the country were under winter weather alerts as a cold, snowy and windy holiday weekend is expected.
