POLAR VORTEX RETURNS

News

That Polar Vortex, which generated freezing temperatures and lots of snow has decided to make a return visit and it is bringing wind chill factors ranging from 0 to minus 40 degrees F.

This Vortex is normal to Arctic regions because of the polar jet stream. But with the polar jet stream in a weakened state, the vortex has decided to mosey on southward, bringing cold temperatures into much of the North and Midwest.

US weather forecasters say temperatures will be colder than normal 30F (17C), and drop to -10F (-23C) in states like Minnesota. Warnings are in place for several other states, including Wisconsin, where meteorologists are warning of blizzard conditions.

Nearly two-thirds of the entire country is on alert for the latest bout of bitter weather as it spreads to the nation's southern region.
