Champlain Valley Weather Discussion:

OVERVIEW
         A strong low pressure center continues to slow move to the Northeast and will eventually end up in the Canadian Maritimes later today. A Tight pressure gradient, is resulting in blowing and drifting of snow, and cold wind chills.

WIND & WINDCHILL
         The biggest concern left with this storm is the strong winds, and the associated wind chills. Winds will continue to be sustained in the 10-20MPH range with isolated gusts up to 30MPH area wide today into tomorrow. This will result in Wind chills today in the 5 above zero to 10 below zero range today, area wide. The warmer readings if you want to call it that, will be in the Champlain Valley, and the colder readings in the higher elevations. Tonight the Winter Weather Advisory will likely be cancelled and a Wind Chill Advisories/ Warnings will likely be put in place for much of the area. Wind chills tonight will be in the 10 below zero to 20 below zero range for the Champlain Valley, and for the higher elevations wind chill values will be in the 15 below zero to 30 below zero range. Make sure if you venture out today, and especially tonight, you bundle up and stay very warm, as it wont take long for frostbite to occur with wind chills this low.

SNOWFALL & BLOWING SNOW
       &nbsb Snowfall for today has pretty much ended, except some light to occasionaly moderate snow showers across the Northern Half of Vermont, and far Northeastern New York. Additional snowfall accumulations today should be a Trace to 1 inch in the immediate Champlain Valley, to as much as 1-3 inches in the more persistent and heavier snow showers towards the Western slopes of the Green mountains.

         The next concern, especially for today is the blowing and drifting of the snow. Strong winds mentioned above in the Wind chill section, will also produce some areas of blowing and drifting snow. The blowing and drifting should slowly become less intense as the snow that's being blown around begins to settle due to not much additional fresh snow. The Winter Weather Advisory is in effect to highlight all the aspects ongoing right now, from the Blowing and drifting of the snow, to the cold wind chills, and the light additional snow accumulations. Travel will be rather difficult today and this evening, so use extreme caution. The Advisory will likely be dropped later tonight and a Wind Chill Advisory/ Warning will likely take over at that time. Stay tuned for further updates.
