I think what CC was seeing could be some partially melted, or flakes with a layer of water on them. Those big fat aggies. It does look like the real mixing is well SW of the city.
The first low in modern history to originate from the Gulf, pelt DC and bury west of them and then head ENE. 999,999 out of 1,000,000 times we'd be heading for a SWFE.
The event next week looks like a Hunchie deal on N and NE for a few inches. The other one a few days later may have some legs, but being the 26th means normal caveats apply. After that, looks like we turn milder.
