Wintry 1/20 - 1/23 Winter Storm

Well at least it ends as some "light" snow in the cold dark with trees through houses and power pole beaver damns along the highway per 00z Euro!

Maybe we can act like it's thundersnow when we hear the transformers going boom boom
 
Given the big ass mfucken run to run changes we’ve seen from amped to ots to amped, I wouldn’t call this a NW trend or really worry about this look being far NW yet
It's really crazy how similar this was to the UKMET - the northern stream just didn't quite dive in as much and it turned out to be a good deal warmer because the mid-level (H85) cold couldn't penetrate as far southeast. Very subtle changes made a big difference.
 
This run verbatim isn't the final solution; I just hate to see it like this. I've seen hints even on the ensembles bringing that 850 0c further and further inland. :mad: Surface temps definitely don't seem to be a problem this time around.

500mb ain't quite cutting it though with the 558dm benchmark for decent cold still up north a ways.

Does this setup look similar to what happened in the Lowcountry back in Dec. 2018? Or was the 50/50 low different in nature? I recall CHS, etc. got a nice snowfall. Plentiful cold air around too. It just didn't go far enough to the west, to help folks out back this way.
 
Here we go with the amped up warm nose crap again. With that track, at least central NC, North and West should be snow. What happened to the ample supply of cold air at 850?
You want the wave diving down to stay more positive tilt as it dives down to get it colder farther east....this time it got to neutral quicker, so more moisture inland, but warmer along the coast. Fine line

The ensemble means have clearly showed the large scale pattern with good
agreement heading into Friday, with a broad and deep trough sinking
across the eastern CONUS following the front. Extreme uncertainty
arises over if/where/when a diving shortwave will ride down the
backside of this trough. The run to run variance in operational,
blend, and ensembles has been very high so confidence is honestly
decreasing in the overall pattern for next weekend. So all that
needs saying at this time is: the overall synoptic pattern is
somewhat favorable for a Gulf/coastal system to develop and enough
cold air would be present for a possible frozen precip event. The
upstream interaction of the rapidly deepening low from Sunday`s
system needs to be cleared up before a more consistent signal can be
worked out.
