When Spring's Last Snow Typically Happens (INTERACTIVE)

(MORE: Where March and April are the Snowiest Months)

We scoured National Weather Service records to compile both the average date of the final measurable (at least 0.1 inch) snow of the spring, and also the date of the latest spring accumulating snow on record. In some locations, that record latest date was in the summer.

Footnotes:

• We only plotted cities and locations whose average last measurable snow of the season occurs in March or later. As a result, among cities not plotted was our nation's capital (average date of last snow of the season is Feb. 24). 
• Since accumulating graupel or hail is also officially classified as snow in daily and monthly climate reports, we made every effort to quality check each "latest snow" record, removing those dates when temperatures were clearly too warm for snow, on which hail likely fell instead.
