The latest snow storm brought snow accumulations of about 9 to 13” in the Greater New Haven Area, which is a lot of snow for any one storm! Typically during November the average snowfall in New Haven is only 1 inch! So we certainly received much more than normal for day and for the month!
I decided to do a little research about how common snowfall is during this early part of November. I got the answer I was looking for on a site called Weather Spark. As you can see in the graph the chance of any snow during this time of November is only about 3%. It’s not until the last day of November that there is usually even a 10% chance of any snow! Also, when it comes to precipitation the most likely would be a moderate rain 43% of the time. But heavy snow is likely only 1% of the time!

So looking back at our latest nor’easter, it is safe to say that it was highly unusual for this time of the season for the New Haven area.
