Snow drifts around a hay bale January 9th

Cold arctic air filled in behind a snow system that brought snow to us on Friday, Highs even with sunny skies were only in the single digits above zero. Clear skies with an arctic high made for a cold night across the area, every recording station was well below zero. One was even below -20.F. I noticed last night my station was 4-7 degrees warmer then other surrounding stations around me, because of this an investigation was done and I found out both my stations did not have lithium batteries, but instead have alkaline, and alkaline batteries have a tough time reading temperatures below -5.F This was likely the reason for the warmer temp. So instead I with with an estimated -13.F for me location last night.
