Another powerful arctic front is moving rapidly across the upper midwest and
Ohio Valley. Areas in Minnesota, North Dakota, Wisconsin, South Dakota and
Michigan will see several inches of snow along with brutally cold wind
chills to -55 below zeroF.

Out ahead of the front in the Ohio Valley, tempertures have reached the
lower 60's and severe weather is occuring almost everywhere along the front.
Wind gusts in Kentucky and Indiana have been reported to be as high as 80MPH
in some places. Behind the front here, expect temperatures to drop some 45
degrees into the lower 20's tonight with wind chills as low as 0.

A few words with the link would have sufficed.

This set up looks like it might be a standard issue for lunar phases
at this time and at this time of year:
