Pattern Fail or Fab February 2023 Pattern Thread

Can we get a NW trend???

From RAH:

Wed-Fri: The surface high to our N is expected to track offshore
early Wed, however any WAA on the back side of the departing high
could be hampered by another weak low that models suggest may form
along the surface front near the Carolina coast. Circulation around
this low could keep cooler air pooling in central NC longer Wed,
leading to cooler temps esp N. With this old frontal zone still
sitting just to our S, eyes then turn to an Arctic cold front
approaching from the NW Wed night with a frigid polar stream surface
high behind it, driven by mid level troughing from central and E
Canada down to TX. Again, predictability is very low at this range
with flow this strong and dynamic, but the pattern overall favors
wetter conditions with periodic rounds of precip, focused on, but
not limited to, Wed night through Thu night. As the Arctic surface
high moves across the Great Lakes and deposits cold air E of the
Appalachians, it`s not out of the question that we could tap into
sufficiently cold air to combine with the in situ moisture and shots
of forcing for ascent to generate a little wintry precip on the NW
side of the precip shield, primarily over N sections as the precip
exits.
Will include a chance of rain areawide and add in a slight
chance of snow mixing in across the N Thu night into early Fri. This
situation is certain to evolve with new model runs and new data
getting into the models with time, so stay tuned.
Temps should trend
down below normal, with highs in the upper 40s to upper 50s Wed but
mostly in the 40s Thu/Fri. -GIH
 
So we some models (euro and cmc)with it too far north and now the gfs with a too far south weak system?
 
Still several GEFS members with wintry precip for this system. Meaning there’s still room for more data to refine models another way. It’s a delicate system and while I’d lean heavily towards nothing happening… I agree with NWS that very minor tweaks could turn nothing into something so it still warrants watching imo but the favored solution is little to nothing along the NW edge of the precip shield.
 
We went from hoping for a SSW to seeing a disgusting SPV rooted to 500mb pattern. Absolutely disgusting and terrible. This is a classsic wound up strat PV pattern, fast flow is gonna continue 5D7FB8FF-5DE4-4D58-9287-C4C3752A03D9.pngD05F3FA6-68E0-4C6A-83C8-0C007EA0ED83.png3EAF19F0-8C3A-4353-8EB5-D5D28BBEDBF6.png
