Winter Storm Winding Down; Warning Remains In Effect For Portions Of The Area

Local Update...
   Snow Winding Down; JRWeather Winter Storm Warning In Effect Until 12AM Thursday For Portions Of Vermont & New York...


JRWeather WINTER STORM WARNING
     JRWeather Continues The Winter Storm Warning for Grand Isle, Franklin, Orleans, Essex, Chittenden, Lamoille, Caledonia, Addison, Washington, Orange, Windsor, and Eastern Rutland Counties in Vermont and Eastern Clinton County In New York Until 12AM Thursday.

     Snow will continue to lighten up across the region, and become more showery in nature, before diminishing shortly after midnight. Across the western slopes of the Green Mountains, the light snow showers may continue into mid Thursday morning. An additional 1-3 inches of snow with locally higher amounts will fall across the Warning area by 12AM. Total snow accumulations in the Warning area will range from 8-14 inches, with locally higher amounts along the spine of the Green Mountains in Vermont by 12AM Thursday.

     A Winter Storm Warning is issued when severe winter weather is likely. In this case the Winter Storm Warning is for heavy amounts of snow. Travel will continue to be hazardous into the early morning hours, as roads are snow packed, and snow covered. Travel should become increasingly better by the morning commute Thursday, although roads will still be slick, so use caution while driving.


DISCUSSION
     Snow is winding down late this evening. I have decided to cancel some of the Warning, after the National Weather Service did. Additional Snow accumulations across Northern New York, and Southern Vermont should be a Dusting-2 inches, nothing very significant. Across Extreme Northeastern New York, and Northern, and Central Vermont, an additional 1-3 inches with locally higher amounts is likely. With the higher amounts across Northern areas, and the lower amounts across Southern Areas. Some convergence is ongoing over the Champlain Valley, and Western Slopes. You can see this on radar as light moisture moves towards the Champlain valley and erupts into widespread light to occasionally moderate snow while over the valley. There is currently one of these deformation/ convergence bands over the Northern, and Central Champlain Valley, and it appears that one or two more of these bands will occur as there is a line of Moisture moving East from the Northern Adirondack Mountains, and another area of moisture moving east from St. Lawrence County, NY. Each round should bring about a half to one inch of snow. Once the moisture hits the Western Slopes of the Green Mountains, it will wring the moisture out pretty good. This is where some isolated higher amounts are possible. Overall total snow accumulations should be 8-14 inches with locally higher amounts along the spine of the Green Mountains. I have had to cut back snow totals for eastern Vermont as mesoscale banding did not occur quite as expected. Still definitely a significant snowfall anyway you cut it. Updated maps below. Stay tuned for any further updates!
