Date of the Last Measurable Snowfall in Spring, Earliest to Latest

The "last snowfall" is the last measurable snowfall following each winter season
The data are listed from earliest last snowfall (January 18) through latest last snowfall (May 5)

For any date after February 28, when it also a Leap Year, an additional day is added to the Day Number (#)
Day Number (#) = calendar day of the year.   For example, March 6, 2015 is Day Number 65, but March 6, 2008, a Leap Year (LY), is Day Number 66

Average, all years, last snowfall = Day Number 87, March 28.
Latest Standard 30-year normal (1991-2020) = Day Number 80, March 21.

Year 2024 Last Snowfall was January 18, Day Number 18
