Meteorological winter arrived on Thursday, and the first couple of days have been relatively mild. There was a bit of cold air at times in November, and even though there were some snowflakes, both Bridgeport and Windsor Locks have yet to see an inch of snow. For the Shoreline, it is not unusual to go at least a couple of weeks into December without seeing the first inch of the white stuff.
Looking at the records dating back to 1948 in Bridgeport, the average date of the first inch of snow is December 17. There have been years where the first inch was as early as October 29 (2011) and as late into the winter as February 16th (1980). If you look at the individual years, then those years really stand out as anomalies compared to what typically happens. The following list is the number of years since 1948 in which the first inch of snow in Bridgeport happened in a given month. *Note – there are a few years with missing data
If you’re in an office pool trying to guess the date on which the first inch of snow will fall at the Shoreline, the most common date (4 times) over the past 60+ years is December 12.
As you’d expect, the numbers are different for inland locations. Today, December 2, is the mean date for the first inch of snow at Windsor Locks. The earliest first inch (since 1949 with 8 years of missing data) happened on October 10, 1979. The latest we’ve waited into ta winter before the first inch in Windsor Locks is February 2 (Groundhog Day!), 2007. In case you’re wondering, the most common date for the first inch of snow in Windsor Locks is December 11, with five occurrences – most recently in 1992.
So, does that mean that we should be looking at the first inch of snow sometime around December 11-12? I can tell you this much…the pattern looks colder in the middle of the month, and it certainly cannot be ruled out!
