I hope you get something this time.  You just never know with these things.  

Thanks man. I’m just too far south to expect much. Lots of jokes from Rockingham people how we are chamber of commerce weather.  Either too far south and East most of the time. Then a good ole southern slider comes and too far north and west. Good luck to you

RAH talking about soil temp issues in January but also mention the fast storm motion and non ideal parent high position:

Today`s probabilistic guidance from the GEFS has increased storm
total snowfall accumulations quite a bit but EC ENS is a bit more
reserved and more realistic looking. There`s a handful of factors
that would lend themselves toward lower snow totals. The lack of a
strong surface ridge over eastern Canada is concerning and while
there is cold air upstream, we`d be much more confident in
significant snow totals if the ridge was parked over Ontario vs
Manitoba. Secondly, the surface wave rapidly moves out of the area
and offshore, really only giving us a good 6 hours of snow potential
vs a slower moving system. Surface soil temperatures aren`t overly
cold either (40s) but that could be overcome with intense snow
rates. Overall given the variety of solutions out there, erring on
the lower end of the distribution seems to be prudent at this time.

that euro run is one of the most ludicrous model runs i've ever seen in my 11 years of following these things. holy hell

The word impressive doesn’t do it justice. Secondary just more or less rots to its demise. It would snow for hours upon hours up this way.

I think for me the biggest takeaway from today comparing GFS vs Euro is both get the low to central Missouri or so but the confluence and HP is very differently modeled. GFS has a 1032 and Euro has a 1035. That is making all the difference with the cold press. Both also have the meso high that @BullCityWx alluded to earlier that really helps enforce things right before game time. This IMO is our best shot at succeeding with something this winter season thus far.

Eric Webb:  

Nice discussion from NWS RAH earlier today. Agree for most part except regarding the apparent unfavorable sfc high position in the upper midwest. What's being forecast is a typical sfc location for a Miller type A (coastal low) winter storm in NC.

There's been a misconception floating around in the Carolinas for a long time that for Miller A winter storms, a parent sfc in the midwest is less favorable than one in Ontario/Quebec. When you actually look at these cases, this isn't true. Mar 1927 is yet another classic example
