Overall the temperature was 0.6 degrees colder than average this winter, making it the coldest since 2005, but still within the average range. I think one reason it didn’t feel like a very cold winter was that it was never really cold for more than a few days in a row and the rest of the time it was just a few degrees below average. We also didn’t really see a mid-winter thaw, as between January 1st and February 13th it only went above zero for a single day.
For most of the winter the precipitation was very low, it wasn’t until late February that some very wet days put us back into the average range. The total precipitation was 220.4 mm compared to the average of 184.5 mm. This is almost double last year’s total of 113.2 mm, but not as much as the two years before that.
As always, it is hard to separate the snow during just the winter as opposed to the entire snowfall season. But, for just the winter we saw about 116 cm of snow compared to the average of 103 cm. However, it was really the 74 cm that came down in February that put us over the top.
