The snowfall on the 1st settled due to blowing and drifting; I measured only 2.3″ at midday on the 2nd, but it was deeper at 11 pm on the 1st, when I found 3″.
January 3: the temperature/humidity sensor and shield were down for maintenance; temperatures were taken from airport observations.
January 25 and 26: Airport had -6° on the 25th. On the 26th, they had -17°; Madison, WI and Rockford, IL both had -16°.
