Back to bundling up!
Another polar vortex has arrived, bringing bitter temperatures and dangerous wind chills to the D.C. metro area.
Tuesday's high is expected to be in the low 20s, and the wind chills will make temperatures feel like 10 below zero.
A winter weather advisory was also issued for Calvert County and St. Mary's County in Maryland.
Monday was actually the mildest of the next few winter-weather days. The next break in freezing temperatures will not appear until Thursday afternoon, when the high will finally scrape above freezing at 33 degrees.
The northeast is not the only area facing the threat of unusually frigid weather. The entire East Coast-- as far south as Louisiana -- is under winter-weather advisory as well, with the rare prospect of snow looming over the South.
NBC4's meteorologists advise to stay well-bundled until the chilly conditions break on Friday, when temperatures will reach as high as 44 degrees. Until then, take the proper precautions to ensure well-being in these wintry conditions including wearing layers and staying indoors as much as possible.
