Stretch of wintry weather continues with more potential snowfall early next week

Though we could not quite replicate late November 2018, the coverage and depth of snow across the high country is really fantastic and I got a first hand experience in it Tuesday ! The Sunday night snow event was terrific, delivering over a foot of snow and much of it coming within a few hours.  We managed to dodge a lot of the heaviest snow squalls Tuesday, but we remain in the midst of a nice stretch of sub-freezing temperatures that should persist through Thursday. 

There are some milder days mixed into the outlook over the next two weeks but excessive torching does not look like a concern. Just as temperatures make a push toward the 40-degree mark on Friday, colder air will make a southward, reinforcing push accompanied by clouds and possibly an additional round of wet snowfall. Clouds are expected for much of the remainder of the weekend and more snow or a snow/sleet conglomeration is expected by as early as late in the day Sunday. 

There's been some excitement surrounding the event for early next week with a few of the model runs showing a healthy, consolidated storm along the southern New England coastline. Another more commonly indicated scenario is for a more disorganized storm and lighter snowfall amounts. Either way, I am pretty convinced this will be a mostly frozen event with the worst case scenario involving a compressing period of sleet. The Greenland blocking is just beast-mode this weekend and although this feature is expected to weaken next week, it will have the impact of keeping the Monday 12/4 event, safely to our south. Conditions could dry out next week if the storminess shifts southeast as some models indicate or we could see some limited instability get put to use in the form of snow showers. Temperatures will sneak above the freezing mark across valley locations but the outlook for the high country looks very sub-freezing next week and that's fantastic with MRG announcing a Saturday 12/9 opening day! 

Speaking of Saturday 12/9, early indications are for more sunshine than clouds with moderating but not especially mild temperatures. Some hints that another weather system could approach for Sunday and this would obviously bring more clouds for the 2nd half of the weekend. The most threatening part of the outlook for the next two weeks is the chance that we manufacture some sort of warmer precipitation event around  the time frame of 12/11. The Euro ensembles are hinting at this, but they are off in their own little corner as other models aren't handling that situation the same way. More generally, the pattern looks decent, powered by the Greenland block/negative NAO situation through the weekend and though we lose most of that by late next week, I am very, very encouraged that the Pacific appears cooperative as we move toward the middle of the month. There are no indications of any type of angry mood with the jet in the Pacific jet this will allow cold continue to build across Canada and stay involved in the day to day weather situation in Vermont.
