Wintry 1/20 - 1/23 Winter Storm

Finally someone with some prestige said it. The term "nw trend" is so over used but rarely explained. More times than not it's only the precip field has expanded nw not the Low itself, although that does happen. Robert did a real good job explaining this back in the day when he hung out in these lowly forums before going big time. Thanks Burrel!
People sometimes confuse the accumulated precipitation output with comparing what is being seen on radar as well I think. A lot of times what is being shown on radar isn’t reaching the ground, and/or not heavy enough to reach the .10 inch threshold to show accumulation on the output. comparing simulated reflectivity with the real time radar would be closer to reality. That’s not to say the precip shield doesn’t verify farther north because it usually does. Just not to the extent that it sometimes seems
 
usually that warm nose is a little further east isnt it ?
Yes, it usually is. I live in the normal warm bubble. In this depiction, the wedge is building in stronger and faster than usual. That warm spot would fill in the next frame surely all else being equal.

EDIT: It also is downsloping given the modeled wind direction. By this frame, the surface flow has turned due north rather than the typical ene wind from CAD.

Where is Webb getting a Miller B from? Isn’t this just a hung up front with a low that develops and ride up the coast?
TW
Yeah, the NAM is Miller A. You can still get a lot of mixed precip types in a Miller A with CAD, depending on the setup. Miller B is a surface low tracking into N Bama / E TN (or NW of there), then reforming along the coast. Miller A / Miller B is very surface low track centric
