NASA
today released this image of the polar vortex, the weird atmospheric
twitch that flooded into the United States last month. The purple wavy
line above that wanders down from the Arctic shows the below-average
temperatures that set cold records in many states.
From NASA's Facebook page:
"The Big Chill - Blistering cold air from the Arctic plunged southward this winter, breaking U.S. temperature records. A persistent pattern of winds spins high above the Arctic in winter. The winds, known as the polar vortex, typically blow in a fairly tight circular formation. But in late December 2013 and early January 2014, the winds loosened and frigid Arctic air spilled farther south than usual, deep into the continental United States. On Jan. 6, 2014, alone, approximately 50 daily record low temperatures were set, from Colorado to Alabama to New York, according to the National Weather Service. In some places temperatures were 40 degrees Fahrenheit colder than average."

GRAND RAPIDS, MI — Don't let the Thursday afternoon sun fool you.
A wind chill advisory is in effect until 11 a.m. Friday following the National Weather Service canceling a winter weather advisory. With snow showers mostly out of the picture, there's now a greater focus on how cold it'll feel when the sun comes up.
"Feels like" temperatures will be at their lowest after 4 a.m. Friday, with some readings approaching minus 25 degrees, according to the National Weather Service in Grand Rapids.
Forecasters say there likely will be a bit of a lull in wind speeds late tonight through the early morning hours, but an approaching weather system is positioned to kick them back up again to about 5 to 15 mph. It won't take much for the wind, coupled with an overnight low of minus 7 degrees, to knock down those readings quickly.
