The great mystery snow of February 1987
As incredible as this event was it's half, just half of what happened in Horsham in late February(or March?) 1987 when I woke up to THIRTY inches of mashed potatoes snow that dropped in early morning training snow thunderstorms! Was predicted to be rain to snow and a couple inches. Still got the scars from missing out on that once in a lifetime event, only saw big wet flakes starting to fall after the change from rain as I hit the sack around 1am.
That one literally melted half away under 50'sF sun by the end of the day and was gone two days later!
* extremely isolated event missed Philly and grazed Allentown some kind of wicked narrow band think it was February 23. Allentown only recorded 6" that day.
* researching what I can I think this snow happened that March, was guessing February 23rd because checking records Allentown recorded 6" that day, but that can't be right because Allentown had cold weather following that storm. I know it was a mild week following the snow with rapid melt.
