Nor'easter To Impact The Region Sunday Night Into Monday








Champlain Valley Weather Discussion:
         The National Weather Service in Albany, NY has issued a Winter Storm Watch for Bennington, and Windham Counties in Southern, VT for the potential of 7 or more inches of snow, along with the potential for up to a half inch of ice accumulation.

         Champlain Valley Weather has issued a Winter Storm Watch for Bennington, Windham, Windsor, and Western Rutland Counties in Southern Vermont, for the potential of 6-9 inches of Snow, with up to a quarter inch of ice accumulation.

         Currently a 1004mb low North of the Mouth of the Mississippi river continues to push North to North-Northeast. Substantial amounts of moisture accompany this system, as it has originated from the Gulf of Mexico. The low pressure system will continue on a North-Northeast motion up to around the Southern portions of West Virginia, where it will then transfer its energy to a new low pressure center that will form near the Delmarva Peninsula, then move northeast, and by the eastern side of Cape Cod.

         This track will allow precipitation to develop across southern Vermont by late Sunday afternoon, and then slowly intensify into the evening hours. The onset of precipitation may fall in the form of Rain or Freezing Rain, but quickly change to a mix of snow, sleet, and freezing rain, and eventual all snow my the evening hours. Snow could be heavy at times overnight Sunday Night into Monday morning. Precipitation should gradual tapper off by Monday afternoon. Total snowfall accumulations at this point appear to range from 3-6 inches in the Connecticut River Valley in Southern Vermont, and the Northwestern Potions of Rutland County to 6-9 inches across much of Windsor, Windham, Bennington, and Western Rutland Counties, with localized higher amounts in the higher elevations of the Southern Green mountains. For Central Vermont, and portions of Northern New York 1-3 inches can be expected, with only a Trace to 1 inch across the extreme Northern portions of Vermont, and Northern New York.

         I would like to urge that models have been trending further to the Southeast since last night. So it appears the exact track and strength is still not known. Any deviations North or South in the track could have a large impact on how much snow falls, and where. Stay tuned for further updates.
