So are we gonna have a nor Easter this weekend or is it going to be beautiful? Models have flipped and flopped (besides GFS which has held firm with no storm)

 Or it could be both depending on one’s location, of course. The NC Outer Banks could have large effects with most of the rest of the SE being beautiful.

 No CMC has had any storm close enough to the E coast to have much, if any, effect on the E coast. The Euro has had 2 with it (12Z yest and 0Z today) with interestingly all of the shorter runs in between (6Z/18Z), which go out far enough to tell, having no E coast storm. OTOH, the UKMET’s last 3 full runs have had it and the newest (6Z) suggests it would also have it based on the last map (hour 66). The first Icon with it any effect was yesterday’s 12Z with the 18Z at least a close call. The 0Z was by far the most ominous with it coming back W at the end. It also had it but then the 6Z had it further offshore though it’s hard to tell if it would have come back close enough to have much effect in the NE. I’m guessing no. It appears based on hour 162 that the 12Z Icon won’t have much effect on even the OB. Edit: confirmed

Full rundown of 12Z main global non-AI for the possible E coast storm next week excluding the not yet released Euro:

The 12Z UKMET, after 3 full runs in a row with an E coast “tropical cyclone”, has no TC and not even an E coast storm as the non-tropical low forms well offshore (300 miles) and then moves out NE from there to just NW of Bermuda.

12z Icon is much further offshore than its 0Z with little E coast effect.

12Z GFS is a bit closer (similar to the 0Z) but like for the 0Z the low still is far enough out to have little effect on the E coast as it then moves out.

OTOH, the 12Z CMC is its first run with effects on the E coast with it getting caught 300 miles SE of the Carolinas and then then coming back WSW to Jacksonville on 10/23. That’s now an extreme outlier pending that the 12Z Euro shows.

 The 12Z Euro still has the E coast storm next week. So, currently the 12Z run non-AI main global models with it are the CMC (its first time) and the Euro (3rd time in a row at 0Z/12Z as 6Z/18Z have yet to have it, which I could tell because 144 hours was far out enough to tell).

 Also, the 12Z Euro AIFS still has it.

Windshield wiper. GFS finally onboard with it too, tho weak and offshore

 The 18Z GFS came well W and is thus the most threatening GFS run yet by far to the E coast with it only 200 miles ESE of Hatteras as its closest! Also, the 18Z Icon has come back W a bit from the 12Z, which itself was less threatening than its 0Z that was coming into the SE.

 Back to 12Z, the JMA has it for its first time and hits much of the SE solidly with this with much of the Carolinas and S VA getting a very beneficial 2”+ of rain the next 8 days:

18Z UKMET is even further away from the E coast than the 12Z! So, as of now, the UKMET is by a good margin the least threatening for a close pass of the E coast!

The level of anxiety this forum would have if this system was in January would be through the roof
