Without a doubt, this has been the coldest morning of the New Year that I can remember. I do recall days of going to elementary school and being held inside for recess because the weather was unsafe due to the subzero windchills outside, mainly because there was always some kid who would lose his stocking hat on the bus ride in from the country or not bring gloves that day, but you never really grasp how frigid, cold weather can cause damaging effects that can last a lifetime.
Last night, as 2018 struck in the central time zone, windchills dipped to -34F, which is nearly at the point where subzero temperatures between Celsius and Fahrenheit are the same. Once -40 is reached, reference or calculation is no longer needed.
Today will certainly be quiet.
