I agree..there have been some really good March storms in the past 10 years that I've experienced while here. I wasn't in this area in 1993, but was in northeast Ohio on the "western edge" of the Storm of the Century. We got nearly a foot of powder and it was in the teens with blizzard warnings for that one in eastern Ohio.
Anyhow, beyond that, 2014 stands as the best year for March events with 2015 a close 2nd. The biggest of all of those was 8" on St. Patrick's Day 2014...which complimented a 5.3" event earlier that month and another 3" on March 25 (2nd year in a row we got decent snow here on my birthday!). And we even got about an inch or so on the 30th that year to close things out. I liked the March 2015 event, 6.5" with temperatures falling through the mid 20s all day. And it stuck around for a couple of days or so. Then of course we had the sleet event in 2017 and the "equinox storm" in 2018 that dropped 5" where I am.
I don't know whether we can pull off a good event this year but I haven't paid much attention to the longer range to be honest. I'd love a shot at one final good event, as this year has been disappointing in and near the DC area at least; too many underperformers. I might not care so much about anything in March, except the event last week was really a bust here; even the models (NAM, in particular) that showed warm air entering the mid-levels were at least giving a couple or few inches of snow before a flip to sleet. I didn't see so much as a single snow flake. It was sleet right from the start and not even anything much to write home about at that (1" sleet total), and the event was over by noon.
I know many here don't care for March snows because they don't stick around for long. But personally that doesn't bother me. If we could score a 6" or so event where we have one nice, snowy day and it hangs around for a day or so before warming up again, that would be awesome.
