Here's the snowfall aftermath that I pulled - my sources for weather back then were confined to AccuWeather on the radio and my NOAA weather radio. There were no forecasts for anything significant...this was a wave of low pressure that absolutely exploded on the east coast near Hatteras. Storm movement of ENE spared the NE corridor - as you can see, the LSV was just inside the high impact area.
This was a very dry snow with considerable drifting - how cold was it? I did not keep records at that time for temps, but DC's high that day was 15. So it was probably around 10 degrees during the storm. My dad measured a drift about 9' high in our driveway the following day.
