March is the most volatile month of the year weatherwise as winter and spring duke it out.
It’s when winter transitions into spring and huge contrasts in air masses make for a nasty March cocktail. A battle zone of air masses results when lingering arctic fronts set up the dividing line between polar air colliding with spring-like milder temps. In this zone, you get massive outbreaks of severe storms and the tornado season launches, starting usually in late March and hits a peak by mid-late April.
But March in Philly has had some record snowstorms, including the infamous blizzard of 1888 when Philadelphia got smacked with 10.5 inches of snow along with winds approaching 80mph along the Jersey Shore.
And of course the very first “storm of the century” March 13-14, 1993, when we got buried with 12 inches of snow and sleet.
