Our chilly but mostly sunny day will be changing rapidly, with possible snow squalls blowing through the Berkshires late this afternoon or early evening. That will signal the arrival of more polar cold, with lows tonight dropping into the single digits below zero and highs tomorrow likely rebounding only into the single digits on the plus side.

Add to that a Wind Advisory in effect until 10 P.M. for winds 15-25 MPH, possibly gusting to 50, and a Wind Chill Warning in effect until 1 P.M. Thursday for wind chills of around 35 below.

Yeah, it's cold, but not that cold.  Folks in the Midwest are enduring midday temps of 20 to 30 or more below zero, not counting the wind chill. At the radio studios of 97X in Davenport, Iowa -- even the antifreeze is freezing, and they have the video to prove it.

It's been brutally cold here in the Midwest thanks to the latest Polar Vortex. Right now in the Quad Cities it is -24 degrees. How cold is that you may ask? So cold that even this antifreeze will freeze.

Station DJ Bill Michaels explains that while it looks like pink lemonade, it's actually marine or RV antifreeze (ethanol).

The antifreeze in your car is propylene glycol. Pink is non-toxic whereas the yellow antifreeze is toxic. They both have different uses and different "freeze points".  But, the point is ... it's so cold today that after only a few hours, a full jug of this stuff will freeze almost completely. And years from now you'll be able to tell your children and grandchildren about the winter that it was so cold the anti-freeze would freeze!
