Sub-freezing temperatures have been plastered all over our faces by ferocious winds over the past two days and similar to what was mentioned in the last update there's more where that came from thanks to storminess that is caught up near the Labrador Sea coastline. The setup brings some intriguing possibilities next week and it's gotten to the point where I am excited to see how and what transpires.
A disturbance brought some snowfall to the Mid Atlantic states Friday and this helped clear the skies over northern Vermont though it was a very windy bluebird day. Weekend weather also looks windy, but not as much as the past two days. We make up for this with more clouds and colder temperatures with readings that should hover in the low to middle teens on the mountain and closer to 20 in valley areas. Limited moisture and the favorable flow should allow for some snowfall throughout both days and late Saturday into Saturday night appears to be the favored time slot for a 2-5 inch accumulation, mainly across the high country. We should expect some clearing late Sunday though I am not sure it arrives before the end of the ski day.
The storm system on Monday appears to be a well organized system and has some moisture. Unfortunately, in this setup, its doinking off the right upright and out into the ocean, an unusual outcome and one that results from the closed area of storminess downstream that will prevent any northward turn. We will get another dose of sunshine out of the whole deal with good visibility on Monday. We can still expect some wind Monday though the subsequent days will be gustier.
Once the Washignton DC snow producing system departs, the door will come open and I hope the party begins. The storminess is expected to linger in eastern Canada allowing the relative warmth there to linger, clashing with much colder air over the frozen western portion of the Hudson Bay. A disorganized conveyor of moisture and snowfall is predicted to develop from all this and begin to drip into southern Quebec and northern New England as early as Tuesday. We have the perfect flow setup for this with north to northwest winds not only blowing this moisture toward us, but also enhancing the impact because of the Lake Champlain thermals. As we get closer, stability parameters might help us predict how heavy the snowfall could become though its quite possible its just moisture from the stalled out storm and not related to stability. Regardless, continuous snow is possible for Tuesday through Thursday and a period of heavier snow is being hinted at Wednesday night into Thursday. Expect strong winds and temperatures not far from 10 degrees while this is all going on which is less treacherous snow to drive in, but could really hamper visibility as wind blows the cold smoke all over the roads and highways.
The weather map finally evolves enough to offer a respite from the wind by the weekend of the 11th and 12th. We could see some snowfall from a clipper system if it comes at us in the right way. Mostly however, if will feel a lot more comfortable thanks to the lower wind speed and temperatures potentially 10 degrees warmer.
Generally favorable setup remains in place through the start of MLK Day but ensembles on Friday are showing a temporary loss in teleconnection support around Jan 13-15 thanks mostly to a surge in AO values. A supportive NAO is helping to keep the upper air signal cool throughout the period and a nearly neutral EPO is expected to turn negative for MLK weekend. It all adds up to a less cold but continued wintry mid January outlook. The big synoptic storm appears elusive for the next 10 days and after that we could see some snowfall potential begin to emerge along those lines.
