I've just been too busy the last couple weeks to track this system closely, but models definitely showed upwards of 0.4-0.5" of precip even down to DC. However, I wonder if some of the north trend had to do with temps/boundary setting up further north as opposed to "well, the storm just went further north". I mean, it did, but I get the vibe that it was at least partly due to it "just not being cold enough" here. Chicken vs egg situation, I guess.
