I just moved under that heavy band just north of Annapolis, near the bay bridge, with some oranges mixed in.

Extremely heavy large dendrite snow coming down now. Haven't seen anything like this tonight. No sleet mixing.

I had a slight funky flake for a few minutes during a lull. Now it just cold smoke dense for snow crazy awesome snow porn. Huge flakes just started.

Of course futile ground for official records, but maybe for the sake of local media discussion, e.g., CWG/WPost, about where this storm places in the DC record books, and well, empirical consistency, the #1- 1922 Knickerbocker 28+ and #2 1899 20+ storm measurements were apparently taken from the central roof of the old Signal Service office at 2416 M Street in the West End (Natural elevation 112 ft + ~50 ft of building height). See http://mrcc.sws.uiuc.edu/FORTS/histories/DC_Washington_DC_Grice.pdf. 

 

Now, I bet several storms after the transfer to DCA in 1950 would have beaten at least the #2 1899 storm if measured at 24th and M.

 

But maybe an official NWS spotter on the board, or at least someone more skilled at measuring than me, would be willing to take a shot at measuring down there tomorrow evening if we're actually close to 28 and the Knickerbocker record.  That specific location is now a huge condo in the West End hotel district, but Francis Playground along Rock Creek Pkwy is one block up 24th with softball and other natural grass fields etc. that could be suitable.

 

Or maybe I should just get some rest and stop geeking out….

Great idea! Any takers?

Someone drive to Olney and take pics of the rain/sleet.

 

it's probably just wet snow.  i was driving through it here in bethesda and in the lull it was sloppier with those mini snowball like flakes that bounce off like sleet.  it can look like rain/sleet when really it's just wet snow/graupel/riming/etc.
