The NW trend of the main surface low track
on the NAM continues. It is now getting uncomfortably close to the coast and is turning more of the coastal snow into ZR and delaying the change to snow. Might Delta score a win with his bold call of a low near or not far from Jacksonville, FL? If this trend continues, rain may soon enter into the equation.
I'm pretty confident that the last 2 NAM runs are being affected by its too high qpf bias to some extent.
Does anyone know why the NAM has no sleet in the transition zone between snow and ZR?
