Thirty-three states from Texas to Maine are on alert Friday morning for snow, ice, bitter cold and flooding as a massive winter storm continues its push east.

With 5,210 flights canceled Thursday nationwide, including over 1,400 in Dallas, the day marked the highest number of weather-related cancellations since March 14, 2017.

Over 310,000 customers are without power Friday morning across Tennessee, Ohio, Pennsylvania, West Virginia, Texas and Kentucky.

The monster storm brought more than 1 foot of snow from Missouri to western New York over the last 36 hours, bringing roads to a standstill.

Indianapolis recorded a record daily snowfall Thursday with 7.3 inches.

The storm brought 1.7 inches of snow to Dallas — more than the city usually sees in an entire year.

The storm even brought freezing rain down to Texas’ Gulf Coast. Police in Houston are urging drivers to stay off the roads due to ice, and Houston schools are closed Friday.

Texans are still feeling the freeze Friday morning with the wind chill — what temperature it feels like — hitting about 8 degrees in Dallas, 7 degrees in Austin and 1 degree in Lubbock.

On Friday morning, the heavy snow and ice are pummeling the inland Northeast from New York state to Maine. An additional 6 inches of snow is possible in New England.

As temperatures drop Friday morning, icy conditions will develop along the Interstate-95 corridor from New Jersey to New York City to Boston. And the temperatures will continue to plummet for the Northeast Friday night, so whatever rain or freezing rain falls will freeze on any untreated roads.

The storm moves out of the Northeast Friday night. But those in the Northeast will wake up to freezing temperatures Saturday, with the wind chill forecast to plunge to 4 degrees in Boston, 6 degrees in New York City and 12 degrees in Washington, D.C.
