That was one of the best boom scenarios. Was at the fire department in Carroll County for that. We got close to 8" when only 2".
Here's the list of LWX products issued that day, courtesy of the IEM Bot: https://mesonet.agron.iastate.edu/wx/afos/list.phtml?source=LWX&year=2013&month=12&day=8&year2=2021&month2=1&day2=22&view=time&order=asc
My wife gave me the "are you kidding me" look about 2 years after we moved and she found out why I love Reisterstown so much. Having 600 ft+ elevation really helps in marginal events.
On the 12z Euro, it appears that H5 is a bit flatter out ahead of the system than it's 00z counterpart. Would be nice to score two solid advisory level events next week.
For those wondering about the cold, the end of the 18z OP GFS has DC not getting out of the upper 20s on Inauguration Day. Sub zero air in Canada and the Great Lakes.
He thinks this is a quick snow to rain for everyone, but admits it's several days off. From my conservations with Wes over the years, he's generally pessimistic about potential snow events in La Nina winters in these parts.
WRT to 12z EPS, the mean/individual members are not as wound up as the OP. It would argue all snow for everyone north of St. Mary's city. Hope we see the GFS start to catch on.
