JonClaw Posted January 21 Share Posted January 21 I like to call VDay 2007 the "Scilia Gel" storm because that's what it felt like I was walking on. Link to comment Share on other sites More sharing options...

kat5hurricane Posted January 21 Share Posted January 21 39 minutes ago, eduggs said: Yes mixing is clearly a concern now with the upper level support well to our northwest on Sunday. Heights and thickness values are surging during the day on Sunday. The CMC shoots the initial shortwave south of Chicago to near Detroit and Buffalo. Then on Monday the ULL is near Sault Ste. Marie... super amped! The Euro isn't too far off. If that's correct, we'll probably have more mixing issues faster than modeled on Sunday. We may not see it until Fri when the NAM is fully in range. The ski areas of the North Country are starting to look great for a long-duration snow event. That's usually a bad sign. The 500mb chart at 0z Monday would look like a rainstorm if you didn't see the preceding panels. I think we should pump the breaks on the Kuchera and NBM snowfall maps and hope for a flatter trof evolution in subsequent model runs. I don't see any models showing mixing issues until the main show is over so I don't agree that it's a big concern now but we need the primary low to stop trending north now, there's less wiggle room than there was 24 hours ago. Sometimes models (the windshield wiper effect) overcorrect in one direction then move back the other way before the final solution so I wouldn't be surprised if we saw some flatter solutions at 0z. Still a lot of solutions on the table. 2 Link to comment Share on other sites More sharing options...

The soundings I am seeing across the models are incredibly cold If the low is as far north as CMC/Euro show then I think we are very lucky that we never get above freezing. If it's further south like the GFS then it would be colder. Link to comment Share on other sites More sharing options...

Up to a few days prior, I believe we thought we were going to have a pretty decent snowstorm. Not like this, but 6 inches of snow I think? It's been almost 20 years.

Winterweatherlover Posted January 21 Share Posted January 21 44 minutes ago, NEG NAO said: definite timing issues have to be worked out as the Euro brings it in very early Sunday morning and wants to mix it here in the afternoon - while the GFS only starts the snow in the late morning If the the primary is further north then I believe precip would come in faster but also end faster/dry slot. If the primary is further south it's slower and the coastal is the show meaning starts later, longer duration, all snow. Link to comment Share on other sites More sharing options...

Winterweatherlover Posted January 21 Share Posted January 21 Basically worst case scenario is 6-10 inches SWFE type setup, a wall of snow followed by mix/dry slot. Best case scenario it transfers quick to coastal all snow 12-18 inches Either scenario is good! 3 Link to comment Share on other sites More sharing options...

Still a lot of solutions on the table. Mixing signals the end of the main show, because once 700mb - 850mb rises above freezing, the WAA is over... lift has moved to our north. The duration before the main show ends has decreased over the past day or two. Mixing is associated with dryslot and a shorter duration of snow, which is why I'm concerned about it. 3 Link to comment Share on other sites More sharing options...

NYC 18 DC 19 Boston 18 Philly 17 This would require the WAA snows plus snows from coastal. I think 6-12 is the best range area wide and that could skew in the 6-10 direction or 8-12. 1 Link to comment Share on other sites More sharing options...

We can all appreciate your need to stay conservative, but we should also stay reasonable. There are several individual ensembles that show less than 6" including some that show a complete miss. There is also still time for modeling to shift much further north or south. We can all see what model consensus is right now. But that doesn't mean we can guarantee a future outcome. 3 Link to comment Share on other sites More sharing options...
