GFS runs with significant SE coastal wintry precip within 1/21-2:

Jan 11 6Z and 12Z

Jan 12 6Z and 18Z

Jan 13 0Z, 6Z, 12Z, 18Z

Jan 14 0Z, 6Z, 12Z

So, 11 of last 14 and 8 in a row!

 The 12Z CMC has ZR later, on 1/23-4, with it still falling some areas especially just inland at the end (fortunately only light along coast SAV northeastward):

 The 6Z GFS was the 1st run since way back at the Jan 12 12Z run with no significant SE coastal wintry precip. during 1/21-2. So, there had been 10 GFS runs in a row like that just prior to today’s 6Z. And not only that but there’s no precip of any kind in any of the SE US 1/21-2! Interesting!

Jan 15 0Z but not on 6Z (1st since 12Z Jan 12)

 A delay of anything in the SE til after 1/22 means a higher risk of not having enough cold air for a storm to intermingle with for widespread SE wintry precip since 1/20-2 is when the coldest of the air has been plunging down and fresh enough for a winter storm. Near perfect timing is crucial for the SE as we know!

WRAL already saying next Wednesday is looking interesting is a higher level of confidence 7 days out than I'm used to

My iPhone apple weather app says snow next Tues.  That's all the confidence I need.

ICON is suppressed, much like its earlier runs. Coastal areas in GA, SC and the FL panhandle get snow. 


 The 12Z Icon gives SAV area 6-8” of snow (7.9” at further inland airport and 6.3” at Hunter near the city). This looks like legit snow on the clown map since 850s are near or just below 0C and 2m temps are in upper 20s and then fall to mid 20s during it. Adjusting down for what Kuchera may have had, it would likely be closer to 5-7”. Whereas that would be amazing and I’d obviously love to see it, SAV hasn’t received that much snow since way back on March 3, 1837! So, SAV getting anywhere near this much snow is, needless to say, extremely unlikely especially since this is still 6.5 days away.

I know that the standard NW trend will probably happen, but if the Florida panhandle gets more snow than RDU, I’m going to think that we’re all cursed for some reason when it comes to snow. Come on winter weather!!!
