Mammoth is apparently doing well via Jebman, but I didn't realize how awful the season has been so far in Colorado. Only a fraction of runs open at the resorts and way below normal snowpack.
You weren't kidding, what an inversion last night. IAD at 23 and my low was 35. I'm not sure when I've ever been up on DCA by 7 degrees for a low.
On the MD Mesonet, the warmest site was Frostburg at nearly 2300'.
Ground is barely whitened and the trees don't have much. At least at my elevation (~450') it stuck to the trees. DCA's measurements always seem suspect, but for the most part they are reality.
