Anyone can if they want. We really need the eps on board though. Link to comment Share on other sites More sharing options...
eduggs Posted January 23, 2021 Share Posted January 23, 2021 Model soundings show dry about 700mb. Upper level divergence and lift are weak. Vorticity is weakening. There's just not a lot of modeled support for precipitation generating mechanisms east of CPA. Maybe things moisten up in the short term. Or maybe a few areas get lucky with isolated banding. Otherwise I think we are looking at a minor event. Link to comment Share on other sites More sharing options...

SnowGoose69 Posted January 23, 2021 Share Posted January 23, 2021 The main system isn’t gonna do it. It’s that 2nd surface reflection that goes up into the Great Lakes and cuts ESE after 84 hours that will do it here. The problem is that might go far enough north that the metro gets rain. It all depends how the block and confluence work. At this stage I think we can say the main event before that doesn’t get much above PHL, if that. 2 Link to comment Share on other sites More sharing options...

All the models seem to be on the train of that weak surface low cutting across and bringing snow. Fine details will take awhile to hammer out. I don’t think it’ll be to get anywhere near as far north as the ICON has it. The more south it goes the more chance we have too that it could pull in some Atlantic moisture to throw more confusion into things Link to comment Share on other sites More sharing options...

Probably the first time a -1 or lower PNA trough out West went against a 5 SD 500 mb west based block this time of year. So details with this one may come down to the wire. isnt that sort of an omega block? Link to comment Share on other sites More sharing options...
HeadInTheClouds Posted January 23, 2021 Share Posted January 23, 2021 12Z runs have been better than 00z. I still think 1-3/2-4 type event. Lets see what Ukie and Euro say. Link to comment Share on other sites More sharing options...

SnowGoose69 Posted January 23, 2021 Share Posted January 23, 2021 The UKMET flopping continues. It’s 12Z run now looks closer to the Icon for Monday and Tuesday than the NAM like it’s 00Z run did lol Link to comment Share on other sites More sharing options...

lee59 Posted January 23, 2021 Share Posted January 23, 2021 To me the storm to watch is not the weak one early in the week, but the potential real powerhouse later in the week, that may pass to our south. Link to comment Share on other sites More sharing options...

No precipitation maps after 72 but I think the UKMET from 84-102 would probably be rainy for the metro like the icon with most of the snow up in the Hudson valley and north Link to comment Share on other sites More sharing options...

I just don’t think it’ll end up that far north. I would think just north of NYC is probably the place to be with that. That event has potential to surprise but we won’t have any details til inside 48. 1 Link to comment Share on other sites More sharing options...
