I know the precip type output shows sleet on WxBell but sounding looks like we just hold onto snow at DCA.
ETA: I realized I added 11p. The 10p sounding does show a warm nose briefly so would mix with some sleet verbatim briefly.
It shows 2” with 1.3” snow depth change by 4p. I’d wager the under on that in DC/inner burbs. I think we’re probably not accumulating on paved surfaces until closer to sunset.
Still, a fantastic run for the area.
