6z is mainly rain from Triad East. low is further west than 0z

These storms usually get the job done for the coastal areas at it pulls away. My guess would be the GFS starts moving further south each run and the Euro meets in the middle. So this could be a run that might pan out. This is THE look you want for everyone in the state. Lots of other states get in on the action as well.

Correct me if I'm wrong, but the blue circle I drew around the dark pink snow...is that thundersnow? 

 

 

With this setup you'd see thundersnow across much of the state. Again grain of salt all that but if this is a solution then a large swath of the state would be under heavy snow and blizzard warnings. Given the cold air in place and the placement of that low RDU west would be getting some big ol heavy flakes. If only I didn't have a business to run and had an extra 3k in the bank for an emergency flight :P

GSP's long term discussion from this morning.
.LONG TERM /FRIDAY THROUGH MONDAY/...As of 300 am EST Tuesday: Friday will provide a brief lull betweensystems as a shallow ridge sets up between a departing shortwavetrough and the next major system amplifying over the northernPlains. We are trying to keep our excitement in check for theweekend system given the spread evident in the operational modelsand ensembles. Uncertainty remains high, but there are trends towardgreater confidence in at least some wintry weather affecting much ofour region over the weekend.The setup will include a zonally-oriented 850 mb baroclinic zoneatop our region just north of the old frontal zone Friday night.This could well provide a focus for moist upglide redevelopingquickly across the area Friday night into Saturday. Subfreezing 850mb temps would permit wintry ptypes at onset in most areas, withmainly snow in the northern tier and possibly a light wintry mixfarther south as profiles wet bulb down. Meanwhile, the deepeningupstream system will dive southeast through the central CONUS thefirst half of the weekend and amplify west of the Appalachians. Run-to-run and model-to-model consistency issues abound, with theoperational GFS now much deeper with an H5 low tracking across theDeep South Saturday night. The ECMWF and Canadian camps depict moreof a positively-tilted open wave crossing the forecast area. Thecommon factors include fairly cold profiles already in place anddecent potential for moisture return ahead of the amplifying system.The main difference is that the ECMWF/CMC solutions would be aquicker hit/shorter duration, which would limit wintry accumulationsa bit more.The GFS, on the other hand, exhibits a far more dynamic southernclosed low position, bringing the heart of its moisture and forcingover the cold air in place Saturday night through Sunday. In fact,the 850 mb low center track on the GFS is perfect for record settingsnowfalls across our region. This solution has the surface lowtracking through southern AL/GA along the frontal zone Saturdaynight and deepening over the SC coastal waters on Sunday. Inaddition, frontogenesis would be robust atop our area in this case,and a lobe of negative EPV crossing the region would even suggestsome potential for thundersnow. However, it`s important to note therecent consistency issues with the GFS runs, and the fact that theGEFS plumes have plenty of spread. Still, the prudent course is toto start featuring the system in the HWO given the potential foraccumulating snowfall.The upper system will depart late Sunday, but with lingeringnorthwest flow snowfall quite possible along the spine of thesouthern Appalachians. Additional height falls may occur back to thewest over the Ohio River Valley on Monday. This early week systemappears a bit more moisture starved, and it seems the betterdynamics will pass north of our forecast area. However, additionalscattered snow showers will be possible in the mountains followingthe wave passage late Monday given the northwest flow upslopemoisture in the residual cold air.

 

Yup!!

Also this is just pure speculation but I've found with these big wound up storms you tend to get a low tracking behind it as nice little bonus a day later. So we could see two rounds. Something to look for a day or two before the storm. 

For those that are robbed by the warm nose during "main" event... the upper level low the next day becomes the main event very often.

Can't afford to see much more amplification than what the GFS depicts. Which is why the Euro is good news. The only other model in the GFS camp is the icon, so I think the full range of outcomes is still on the table

Agree. GFS overamping and Euro pushing south right now means a solution in the middle will be good for everyone.

@burgertimebeen following the Icon on this. It’s the model that digs the least just fyi. 0z Canadian made a huge jump toward the GFS. Curious to see what the 6z did but I don’t have access to that. I can’t remember the last time a Manitoba mauler did this. Been a long time 

Here it does extremely well in the 84 - 100  hour range but is a bit useless beyond that. 6z looked to me like it's starting to cave to the GFS too just doesn't know it yet lol.
