I remember that front in 1977 that WinterWxLuvr mentioned. We were under a blizzard warning in Cumberland when they let us out of middle school early. Perplexing as we were boarding the bus in sunny, balmy weather.
By the time I got home, the sky was black in the west, like a wall cloud in summer. We ended up with a few inches in the valley but the Appalachians scored big. And the wind was as advertised.
Also remember a frontal passage in November 1995 that dropped some accumulating snow behind the front when I was living in College Park. Dramatic temperature drop that day also.
