I was just doing the same thing on TT (at least between GFS / NAM). Agreed, it looks to my weenie eyes that the NAM has a slightly sharper ss s/w and a touch more phasing.
It’s freaking wild outside. Temp dropping like a rock (7 degrees in last 15 minutes). Heavy rain with gusts into the 30s already. Ice pellets mixing in so the flip to snow is close.
Just got here. 45 and winds are still out of the SE but look to flip out of the NW soon.
Viz was less than 10 feet on some parts of 68 due to the fog. Despite the temp here, the hill up to our house was really icy.
