Cool beans! We learned a new term this week–polar vortex. According to Al Roker and the like, it’s a blast of arctic air that circulates in a cyclone pattern and causes temperatures to dip ridiculously low. It’s estimated that some 187 million of us could be affected by this polar whirlwind thingy, causing temps to dip to -16 in Chicago, -13 in Fort Wayne, Indiana, and a mere 8 degrees in Atlanta. But before you get yourself wound tighter than a woolen scarf, relax. Mother Nature blows hot and cold. The big thaw is coming this weekend, when temps ricochet back into the double-digits. Toss the mittens and break out the tshirts!
