LP08 Posted December 31, 2024 Share Posted December 31, 2024 Just now, SnowenOutThere said: Adding onto @LP08 post about the confluence over the northeast, but when messaging @brooklynwx99 about why the GFS sheared out the storm on previous runs they mentioned how it was running into a wall of confluence, so naturally it would have a hard time holding itself together. I think our biggest concern as of now is actually getting less confluence over the northeast so it's able to have precip get to us, right now the concern is more suppression/shearing than cutting. So when watching future model runs I think one of the most important pieces to look at will be where the wall of confluence sets up over the northeast. Here are the runs of the GFS and EURO to make that point Also take a look at the Height lines off the coast. Bob chill always famously said they are like train tracks. You are not going to come north with the GFS look. 3 Link to comment Share on other sites More sharing options...

LP08 Posted December 31, 2024 Share Posted December 31, 2024 CMC has more NS influence that kind of disrupts the main SW with a phase attempt. At least that what it looks like to my weenie eyes. Link to comment Share on other sites More sharing options...

It's not a juice problem as I see it - it has the juice til it hits our doorstep. It's the 1-3/4 wave running interference. ICON/EURO have better spacing... though honestly my one issue with the 06z EURO that I didn't bring up was a negative trend in that direction. 1 Link to comment Share on other sites More sharing options...

rjvanals Posted December 31, 2024 Share Posted December 31, 2024 Looking at the 500 charts the Friday system organizes closer to shore on both the CMC/GFS compared to the EURO/ICON which then helps push the confluence further south on Monday screwing it up 2 Link to comment Share on other sites More sharing options...

87storms Posted December 31, 2024 Share Posted December 31, 2024 The argument could be made that this is the perfect spot to be in. You do not want to be in the bullseye at this range...it almost never works out. Late trends north are still a thing as is over-fitting of cold air/suppression (or so it seems). 2 Link to comment Share on other sites More sharing options...
Terpeast Posted December 31, 2024 Share Posted December 31, 2024 I wouldn't react negatively to more confluence pushing this storm south. I would always leave the door open for a last minute north trend, so we're sitting right where we want to be sitting imho. There's always a chance that the first system off the coast is going to be overdone, and with an active NS, the 50/50 low might get pushed a bit to the east. It's trending stronger, sure, but I think there will be more progressiveness to it than what the models are depicting 6-7 days out. 5 1 Link to comment Share on other sites More sharing options...
NorthArlington101 Posted December 31, 2024 Share Posted December 31, 2024 As @Bob Chillsaid earlier - the WAA should at least be good for someone. Another tricky feature to place but someone from Raleigh-NYC should get 3-6" from that alone. 7 Link to comment Share on other sites More sharing options...

We're not going to have a good handle of next week until we see what happens with the Friday system. I'd like to see that form way offshore and then take my chances with next week Link to comment Share on other sites More sharing options...

WEATHER53 Posted December 31, 2024 Share Posted December 31, 2024 I expect suppression to be indicated repeatedly as this is extreme cold . However we can have 30.55 extreme cold which is suppressive or 30.25-35 which is not. That gets revealed 12-18 hours in advance. Location of the high vital also. On or <100 miles south SSW of tip of Hudson /James bay is ideal. The further east and south it centers itself not as good. Pittsburgh colder than Boston shows we have very good cold air support west of DC Link to comment Share on other sites More sharing options...
stormy Posted December 31, 2024 Share Posted December 31, 2024 The GFS was suppressed south which is no big deal at this point. The GEM is also suppressed south which brings it right into my backyard. 1 Link to comment Share on other sites More sharing options...

WxUSAF Posted December 31, 2024 Share Posted December 31, 2024 For the period around the 10-11th, you can cycle through the 500mb vorticity panels of the last several runs and see what we need quite clearly. When our 50/50 low is sitting over Vermont, there’s no storm. 6 Link to comment Share on other sites More sharing options...
