I generally hold out hope around here for one more good event in March each year. Of course "good" is relative, but at any rate I normally think it's reasonable to expect a measurable or better snow most Marches even in the DC area.
This year, I still am hopeful we'll see something more than a few mangled wet snowflakes and 35-40 degrees before we're done, though that's dwindling in a hurry. Let's be honest: the current indications aren't exactly pointing to much of anything, other than maybe a few days of chilly and dry right now through the next week or so. I kind of hold out hope that maybe next weekend will "show up" again but who knows. This isn't like 2014 or 2015, or even 2018, where you could see indications in the longwave pattern that we could score some good snow events. I honestly just don't see that at this point. So I don't blame anyone just finally saying "it's over (except perhaps for regions outside more favored areas)." You are correct, things certainly could change over the next week or so, and we've seen that often this year, so I guess we'll see.
ETA: I definitely don't care for a "torch" even in March, though some have said "bring it on". Hell, we'll see plenty of hot weather guaranteed until late September!! I'd be fine with some good, mild spring weather where you're not sweltering. Don't care to see even the 80s for a little while yet, thank you very much!
