25 inches measured at Harpers Ferry, WV. I have a 120 foot long driver and I thank God that I have a snow blower.
I will say one thing that WFO Sterling office did an outstanding job on this event. They put out a Winter Storm Watch on Wednesday afternoon for Friday morning thru Saturday and then followed it up with a Winter Storm Warning on Thursday. They forecasted 20 to 30 inches starting on Wednesday, which verified very well. The winter storm warning mentioned locally heavier amounts. Kudos to the WFO Sterling office for a job very well done.
