Skies were just partly cloudy overnight and early this morning and winds calm or very light at many locations, allowing enough radiational heat loss over a still fresh snow cover to see temps drop into the single digits with sub-zero readings along and west of Interstate 39.  Lowest temp was -4 at Rochelle and the coldest wind chill reading -14 at the same location.

Readings will be on the rise today as winds pick up out of the southwest – highs reaching the mid to upper 20s.  The warming trend should continue into the latter part of the week.
