If it pans out, I demand Rotunda snow photos. Nobody has provided this subforum that service since I graduated in 2022. Best snowstorm scenery in the U.S..
Unless we are concerned about sun angle (maybe we are) my favorite part of the run is that it doesn't really go below 29 degrees in DC. For you that means mid/low 20s. I think you'd accumulate at those temps, though I understand we'd all like it to be heavier
