Wintry January 3rd-6th, 2018 Winter Storm The ARCC/Xtreme Weather Special

ya the chaser is slower this run a bit, lets see if it can catch up....lead wave is slower as well
 
The s/w over the Hudson Bay digging more is one reason why our trailer looks slower & weaker, the more it digs, the more the heights to its west rise, which slows down and weakens the trailer a tad. That trend needs to come to a halt
 
This run, likely a no go. Too slow with the secondary wave.

The trailer is starting to catch up at hr 60. its not that far off from the 18z run. it has DEF been slower this run, but it appears to be catching up

I know that's a positive tilt trough, but what do you call that type of orientation? Shouldn't the wave be more in a upright "U" shape for a storm system to form?
 
The overall longwave looks more positively tilted this run, we need that northern stream trailer to dig deeper into the side of the ridge over the west coast... The SLP developing closer to FL has more to do w/ the GFS's convective feedback issues rather than synoptic-scale flow changes
