Charting 36 wind-chilled hours

Wind chill temperature forecast for the District between 8 p.m. Monday night and 8 a.m. Wednesday morning.
The cold and wind are here and mean business. For at least the next 36 hours, the sinister duo generate wind chills struggling to exceed 15 degrees during the day and 10 at night. Early Tuesday and Wednesday mornings, the index tanks into the single digits -- to as low as 5 degrees.
The chart above is based on sustained winds - expected to be in the neighborhood of about 15-30 mph during this stretch. If you factor in gusts of 30-40 mph, wind chill readings could briefly plummet to zero or a few degrees below, especially in the colder suburbs late Tuesday night or early Wednesday morning.
I'm ready for a hot, steamy beverage.

I'm the opposite of a snow lover, but reading posts like this make me wish there was a blizzard to coincide with these temps/windchills so I'd have an excuse to not go out in it!

All right, first person to report on this! Snow falling outside right now in McLean. Already a dusting on the deck. It can't have been for long. Very pretty sight.

As I look at the radar at 11:45 and went out to feel the snow here in Spring Valley, I couldn't help but notice that it was banding like in the lake effect radars I see in traditional lake effect areas. Additionally, at the radar at 11:45, the band was directly over the Potomac: can the wide Potomac make "river-effect" snow much like the Great Lakes?

Really coming down nicely in SW DC. More than a dusting so far, and because of the cold, it's sticking to everything. Lovely!

@bloodynose
Potomac isn't a big enough water to produce "lake" or "river" effect snow. Looks like this snow band may have originated from Lake Erie and is being enhanced by an upper level disturbance over the region.
