Although this winter so far has not been nearly as cold as we recorded last year, we have yet to accomplish something we average six times per winter. What would that be? We have yet to observe a high temperature of 40° or higher since the start of climatological winter on December 1.
The last 40° day occurred on November 30 when the high temperature was 45°. Since then the warmest temperature of the winter season has been 36° recorded on December 1 and on January 22 and 23. The winter of 2008-09 brought two 40° days to our area and the previous winter of 2007-08 was the first winter since 1981-82 without such an occurrence during the three principle months of winter.
This lack of milder winter days has been a general trend in the past two decades with only four winters since 1991-92 having above average 40° winter days. This can be attributed mainly to our more persistent deeper snow cover in recent years.
