Last Below Zero Weather of the Season? I Hope.

Here are the lows this morning, courtesy of the National Weather Service office in Lincoln. Areas in blue were below zero. Champaign-Urbana reached -9 degrees, breaking the old record of 4 degrees set in 1899.

Of course, widespread snow cover (map below), clear skies, and calm winds were contributing factors in the hopefully last round of below-zero weather this season.
