Down to the teens last night.  Never got above freezing.  With the recent snow, this is what early March in Wisconsin is normally like.   Winter is starting to break.  The teens are a warm-up from the single digits or even below 0 from January and February.   March is a changeable month.  At the beginning of March 40 is warm.  By the end of March 40 is cold.    The warm winter this year upset all that and triggered the early maple season.   

Tonight is down to the single digits.  Tomorrow barley breaks freezing.    But the cold spell is short lived.  By Tuesday and Wednesday we warm to highs of 40s and should have freezing nights.   This should be good sap weather. 

No activity in the woods today.
