6.47 miles, give or take a few feet.
More seriously, I always take "N&W" to mean changes start at the fall line, with snow amounts, ratios, whatever getting better as you go further N&W from there.
Hopefully this should help quell some of the inexplicable moping about likely snow vs. mix amounts. Also, the trends in the past 12 hours have largely been stable -- a little colder, a little warmer, some small changes to total QPF. I didn't stay at a Holiday Inn Express last night but I just don't see anything right now that would suggest further dramatic changes.
To be fair, I am not sure that’s what the AFD says. It says ratios start at 15-18:1 and trend down to 7-10:1 over the storm. Depending on the initial thump that could well average out to higher than 10:1 over the full storm. In theory, Kuchera should capture this but we all know that it is far from perfect.
Getting rid of the mountains seems extreme. They are pretty. And CAD is nice. Better idea is just to make them retractable. Lower them into the ground when a storm is coming. Lift them back up after we get our 3 feet of beautiful powder. LFG team. We can figure out how to do this. It's just basic physics (and perhaps a little geology).
