one last band trying to move E/NE from Loudoun County, if it holds together could give much of Central/Southern MoCo a bit more accumulation in the next hour or so.

measured about 1.5" on my deck railing, not as accurate as a snowboard measure, but considering a bit of compaction possible I'll take it! Wasn't expecting more than an inch up this far (NE Gaithersburg, close to Laytonsville)

have to say that overall this was fairly well predicted by the models, Euro gets props for having been the earliest and fairly consistent to predict that places even north of DC up to around I70 would get measurable stuff... and the timing of when it would begin and (soon) end was accurate as well. Some of the other models were late to the northern shift but did catch on as we got closer to the event.

clearly they built that stretch of I-70 to coincide with the northern extent of the green portion of the precip! Pretty much in line with much of the model predictions as to where the cutoff would set up?

18Z RGEM about the same as previous run, maybe just a hair better but mostly noise I think

let's see if King Euro comes back north as well and joins the rest of the 12Z model suite. It might as well finish what it started, right?

yep, no more snow for us on the 18Z, everything shifted significantly north - northern New England and interior New York get a good snow from this run.

and now the 12Z GooFus has backed that up to 12/3!

nice break in the clouds over MoCo, full sun here in Gaithersburg (near Laytonsville)!

12km NAM doing its NAM thing on us, look at all that 1+" purple!

latest 18Z GFS painting over .75" QPF for much of our area, has been trending upward:

BWI: 17.8 DCA: 11.4 IAD: 19.5 RIC: 8.5 SBY: 7.5

is it stationary because something of an equilibrium has been (temporarily) reached between the competing steering flows?

both HAFS-A and HAFS-B (12Z) models showing a direct hit to Kingston with around 940mb, yikes

given that it comes in around Halloween, it would seen that the CMC run is trying to look really... scary. Presumably the 0Z run will be like Monty Python says ("And now for something completely different")
