Wow at this SN+, the southern edge of these bands overpeforms the northern parts.
I think I undermeasured earlier, did a more broad survey of undisturbed areas and am finding 11 inches in Takoma Park.
Latest HRRR says DC is in light snow until 11 pm, we'll see how it goes of course but its encouraging, perhaps at least snowtv all day and night. 2-4 more inches if you believe its QPF.
