Wintry Dec 8-10th Winter Storm

A lot happens in between those two frames, can't tell if it's good or not. Does it stay on the coast or go inland? Does the high hang in there? How cold? Initial location of everything looks good though.
Yea, weathermodels.com has the 6 hourly frames in between 120-144, just hasn't updated yet. Looking through the 24 it looks better than 0z.
 
Here is the single most important trend we need to watch.

Notice the energy in Montana. That northern energy is key to the outcome of the low track. Also notice the SE trend with our southern energy.

This has increased the gap between the northern and southern pieces of energy and has allowed our LP to make it further SE before getting caught up as the northern piece phases into the southern.

this is 5 days out so this trend is likely a legit semi-permanent trend.

FV3 went gangbusters but our low went boom. We are flirting with disaster (rain) if this happens
 
An absolute drubbing on the FV3! Again! I can't wait for the rest of the panels to load.

It's been fairly consistent, in contrast to the old GFS. I just hope it's not consistently wrong though...
 
Upstate just got raked. Snow maps will look like the 12z Euro at the yesterday. Wowzer. Amplification is starting to scare me though
 
Central/Northern AR and Northwest TN getting hammered this run on the FV3. Would like to see those amounts trending a little further south.
 
BOOM!!!!!

FV3 brings the LP north at 132 then back south at 138. Not sure I buys that, Actually brings it into SW GA at 132. Have not seen a LP track like that before.
