Forty-six to go

This past Sunday evening, December 9, the temperature dropped below zero for the first time this season.  Last year we also recorded our first negative low of the season on December 9, although, it occurred during the more traditional early morning hours.  The long term average date for such an occurrence is on November 28.

Not only has the first below zero temperature of the year occurred later than average the past two years, but that has been a trend in recent years.  Only three out of the past thirteen years has our first negative occurred earlier than the average.  Although, it should be noted that almost all of those years, like this year, the first negative temperature did occurred during the early part of December.

Because the temperature dropped below zero Sunday evening and it remained below zero into Monday morning we have now recorded two below zero days this winter season.  Our cold season average is 48 such days.
