Maybe I slept through it but did not hear thunder in Kemp Mill . I think the temp drop and wind shift and increase will be fun even if any snow is 4am ish and rougher to witness that
DC has kicked off some very good winters with early-mid Dec mega fronts which have ample moisture remaining post front. The post frontal moisture is a pattern that continues usually. When that kind of temp drop occurs in 2-4 hours there is usually real good support aloft temp wise
