Past tracking has shown the graphs plummet around 36 hours out (from model init) a few times this season. That would be the 00Z runs tonight. We're looking good, but by no means home free. I'm crossing all available appendages
IDK, if I'm not mistaken, I believe DCA tends to report really low snow totals at or near local minimums. This is especially true in marginal events like this one. Also the fall line and R/S line aren't the same thing.
If it busts and snows 1", you'll brag and 95% of the board will put you on ignore. If it snows 6", everyone will put you on ignore the next time you cry wolf. Doesn't seem like a win-win to me.
The GFS has a discombobulated nonsense system that gives nobody in NOVA/MD significant anything. It does, however, support snow this evening for parts of NOVA. Spoiler alert: it’s probably wrong about this evening based on the EURO/NAM/PARA/HRRR
