On 17 October, the Waterloo Airport had its coldest low temperature to date of 22 degrees. That remained the coldest temperature until -5 was reported Saturday morning. That 27 degree difference in the coldest low temperature to date was the largest on record for the site! The yearly largest low temperature to date drop is presented in the featured chart for Waterloo. The conditions this year created a near perfect situation for this large of a change to occur. Up until our recent snowfall, overnight low temperatures have been warm for the season. Our first snowfall created a deep and fresh snow pack that allowed for temperatures to plummet quickly one night as the skies cleared and winds were calm.
