Go wonder - there's also less common species mixed in that were actually more stubborn than the oaks, that were adding still green and those are flushing over brown/orange quickly.

I'm half snarking for fun - I agree with your sentiments. Even a decent pack of 12” loses its “White Christmas” luster if it’s 44F, raining with 1/4 mile thick fog and blackened snowbanks. Sure it’s a “White Christmas” but despite a foot on the ground, there are soggy water runnels and pea soup views outside… whereas even a fresh 2-4” on grass and on every twig and branch probably achieves a better festive atmosphere with 70% less snowpack.

On the flip side, there were some places (mostly S of pike) that did not get a white Xmas in 2002 because they had bare ground and the snow didn't start accumulating until about 8-9am in spots. So that was deceptive too. I think some spots in far SE MA had this happen in 2017 too...the rain flipped to snow there around 7am but they didn't have an inch yet...so it officially goes down as a brown Xmas even though they prob were snowing 2" per hour between 7-9am. 1 Link to comment Share on other sites More sharing options...

DavisStraight Posted November 9, 2021 Share Posted November 9, 2021 I would rather have an inch or two of crust Christmas Eve and Christmas day than a foot a powder get melted by heavy rain on the 24 th, which has happened. Link to comment Share on other sites More sharing options...
ORH_wxman Posted November 9, 2021 Share Posted November 9, 2021 Getting back to the "threat" next week....as Tip said, this wave is probably going to cause some model waffling. It comes in screaming on kind of a "flat" flow. You can see it here at 90 hours on the Euro And even now the 84 hour NAM at 18z "sees" the wave as well. This is the one to watch....you have the lead deep trough out ahead of it and that wave will try to amplify into the back side of that large trough. That's kind of what you are looking for this early in the season because you typically want some fresh CAA to put a decent antecedent airmas in place. It's not the greatest airmass, but might be enough for interior and esp elevations. Something to watch at least....we'll see if it is still there in another 48 hours.

I’d have to check but ALB in 2002 I think we woke up to bare ground on Xmas day… that huge storm started at like 9-10am IIRC. Then we had 18” by the time I was driving my grandmother home that evening and finished with 22” at my childhood house. Snowing 3”/hr during Christmas Dinner was awesome. But despite like 18” at ALB on the 25th, that 12z morning ob might have been grass. Link to comment Share on other sites More sharing options...

By the time I left my brothers house shortly after xmas dinner, the snowpack had been vaporized. temp of 57, DP of 56 nuked that pack in a hurry.

I may have officially still had an inch or two of slush at 7am last year....but it was so disgusting I'm not even counting that as a white Xmas. It was funny because Xmas eve was amazing....like 50-55 but still a foot of snow OTG and filtered sun. My boys were outside most of the day playing in it and we had a fire going in the fire pit outside. It was quite festive....almost a Reggae-fest atmosphere you see at ski areas in late March on those warmish days. If it weren't for the horrific rainstorm that started later that night, it probably would have just been a typical warm day that melts 3 inches of pack but not much else.

I really don't trust either model Euro or GFS. In our state and Connecticut 1 meteorologist from a certain Network loves the Euro, where another meteorologist from a different network loves the GFS. It all comes down to as we get closer to the storm and as the models converge. It happens every year and probably what makes each other crazy. That's what makes it fun LOL Link to comment Share on other sites More sharing options...
