The two personal weather stations right near, but across the river from DCA were 22 and 21 for lows.
Can I complain about IAD being ridiculously low when my low was 17?
Added 1” on 0.09” precip beyond 7am yesterday, for a total of 3.5” on 0.30” precip. Good ratios, we were just too far south for the good stuff. Congrats MD and LoCo.
