Meteorological winter it's just a little over 3 weeks away. The pattern is going to give us a taste of winter like temperatures as arctic air drops south and plunges far south as the Gulf of America and into southern Florida.
I've been posting a lot of details over the last several days On this storm it's coming through. Not much has changed and all of that Deal more with who's gonna see the accumulating snow So this post is going to concentrate more on Snowfall and who might see what along with projected possible snow amounts.

We have that Alberta clipper Working its way through A long with blocking sitting up over Greenland. This is gonna force the arctic air behind the clipper to move way to the south.
As I've been saying for the last several days that an Alberta clipper is going to drop out of Canada and Track southeast diving under the Great Lakes. We can see this on the surface and 500MB chart. From here it's going to be heading towards Ontario and Quebec. A head of this We will see rain showers Then as the temperatures drop these rain showers will change over to a mix and then some snow showers especially in the higher elevations. This is going to produce a swath of snow From the Upper Midwest down through the Midwest. The storm is going to be deepening as it slides under the Great Lakes, parts of Michigan into north west Ohio and northern Illinois could see 3-8 " of snow With some areas in Michigan seeing as much as 14" of snow. West Virginia And the high level Of the Appalachians Could pick up over a foot. The Providences of Ontario and Quebec will get walloped with accumulating snow with 8-12 inches (20 - 30 cm) of snow very likely with snow totals of over a foot very likely with localized areas seen as much as 14-16 inches (35-40 cm).
For here in the Northeast, The Adirondacks look to pick up 2-6 inches during Monday and Tuesday. The Whites and Greens Picking up 1 to perhaps 4 inches of snow. The Berkshires Catskills and Poconos will see snow flurries develop with accumulations of a dusting to a couple inches possible. The lower elevations of northern New York State and northern New England could see a dusting or so even in the valleys.
Behind a clipper, Arctic air is gonna move into the region as that upper level low that has been up over Hudson bay drops south with that dip in the jet stream. Those downwind of of the big lakes, especially southeast of the lakes Erie and Ontario will likely pick up 3-8 inches, with a foot to possibly as much as 18 inches in some localized areas.
Behind the clipper for the rest of the week. The Northeast is going to see reinforcing shots of cold as several troughs work their way through the Northeast, Keeping things cool and unsettled.
Things are still evolving so things could change a bit but this is basically how it looks to go at this time
Thanks! Do you think the drought-y conditions are going to impact snowfall potential?
ReplyDeleteNo that shouldn't be a factor. But what will help limit the snow amounts will be the marginal temperatures on the front side of all that Arctic air that's pushing in, that otherwise would have been a big snow event.
DeleteThanks.
ReplyDeleteWelcome
DeleteA couple days ago you mentioned how you liked using the 850mb because the temperature difference was not that great.Reading that made a question that I have wanted to ask pop Back into my head.
ReplyDeleteDuring the winter months especially when it is colder out .I always hear a roaring sound up above the the houses.No matter where I am up higher at 2000 feet or at 2800 feet.When I would be in Vt.in my bunk at camp from( this time until the Sun after Thanksgiving ) and the roar would be there.The question is is this the wind blowing at higher altitudes.I hear it but do not see branches at ground level move.How high up is 850 mb and how high is 500 mb
Generally 850 millibars Is a little over 4,700 feet Where is 500 Millibars Is generally over 18,000 feet. The speed of sound and the distance it moves Is greatly dependent on atmospheric temperature and density . It is possible That what you're hearing Is because of those factors along with a chance for a Temperature inversion over your head Help helping the sounds travel further
