Polar Vortex, Back-To-Back-To-Back Winter Storms Target Eastern Half Of US

Snow, sub-zero temperatures, and frigid wind chills.

The week ahead will have all of that. Spring is just… two months away.

It could easily turn out to be the coldest week of the year in the Hudson Valley as a lobe of the polar vortex, which typically sits near Greenland, swirls across the country. Watch:

A winter storm warning is in effect starting Sunday afternoon. It’ll turn out to be a good, old-fashioned snowstorm for the area.

Here’s what you need to know

• What? Snow, moderate to heavy at times.

• When? Starting between 1 and 4 p.m. Sunday from southwest to northeast. Ending by 4 a.m. Monday.

• How much? 4 to 8 inches of powdery snow.

Impact? Roads and sidewalks will become snow-covered on Sunday afternoon. The heaviest snow will fall during the evening, when snow rates could reach an inch per hour and travel will be most treacherous. Temperatures will drop into the single digits early Monday as the storm departs. The powdery nature of the snow will make it easier to clear.

The week ahead

The rest of the week looks very cold but probably dry in the Hudson Valley. Wintry weather is expected from Texas to the Carolinas on Tuesday and Wednesday, with travel grinding to a halt as a major storm brings snow to places that don’t have plows! Houston, New Orleans, Tallahassee, Charleston, and Myrtle Beach are among the places where significant snow may fall.

It could be the biggest snow storm on record in parts of the Deep South, where snowfall could eclipse half a foot in some places. The deepest snow depths across that part of the country generally happened decades ago, so the event will be unusual and rare.
