To the naked eye on my cell phone, the main driver of the differences between models / individual runs doesn’t seem to be track. All of the models show something pretty similar in that regard. The difference seems to be whether or not the low is more or less organized and whether the wave gets torn apart by the Apps. The solutions with a more organized wave have a more mature precip shield. Snow is definitely heavier and the extent of the precip shield is further north. CMC HRR ICON all look pretty decent for CMD and points S and E. The latest HRRR adjusted north with the precip shield, but the track itself remained pretty identical. 2-4 hours of heavy snow for the DC - BAL corridor per the HRRR would leave a lot of folks smiling - minor event or not. Would be really nice to see us come out on the winning side of a potential wave, even if it’s not a biggie. Loss after loss after loss when you’re tracking is just as depressing than the lack of snow itself. .
