If we’re talking about Jan/Feb 2021 we got unlucky as the storms hit to the south of DC or just north of DC https://www.washingtonpost.com/weather/2023/12/27/dc-snow-hole/
We also had the storm around Presidents’ Day where a small warm layer at ~5000 ft turned a 6-10 inch snow event into a sleet fest around DC despite cold low level temps.
We probably had a bottom 10 percent outcome for that set up and I’d take our chances w it again.
