Winter Storm Continues To Impact The Region

Local Update...
   JRWeather Winter Storm Warning In Effect From Until 11PM Tonight; JRWeather Winter Weather Advisory In Effect 8PM Tonight...

JRWeather WINTER STORM WARNING
     JRWeather Has Continued The Winter Storm Warning for Lamoille, Orleans, Washington, Eastern Franklin, Eastern Chittenden, and Eastern Addison Counties In Vermont Until 11PM Tonight.

     Snow will continue, heavy at times today, especially across the Western Slopes of the Green Mountains. Total snow accumulations by late tonight will range from 6-9 inches with locally higher amounts. Along with significant snow, winds will be gusting up to 35MPH during the day today. This will cause significant blowing and drifting of the snow. Hazardous travel conditions are likely for this evenings commute.

     A Winter Storm Warning is issued when severe winter weather is likely. In this case the Winter Storm Warning is for moderate to heavy amounts of snow, and blowing snow. Stay tuned for further updates.


JRWeather WINTER WEATHER ADVISORY
     JRWeather has continued the Winter Weather Advisory For Western Franklin, Western Chittenden, Western Addison, and Western Rutland Counties in Vermont, and Clinton, and Essex Counties In New York Until 8PM Tonight.

     Snow will continue to day and be occasionally heavy at times. Total snow accumulations by tonight will range from 3-6 inches. Along with these snow accumulations, winds will be gusting up to 30MPH during the day today. This will cause blowing and drifting of the snow. Travel will likely be hazardous for the evening commute.

     A Winter Weather Advisory is issued when there is a strong likelihood of significant but not severe winter weather. In this case the Winter Weather Advisory is in effect for light to moderate amounts of snow, and blowing snow. Stay tuned for further updates.


DISCUSSION
     Yes I had to change things once again. Instead of waiting it out, to see what the precipitation shield would do, I cancelled the Advisory off the untrusted models. Now that the snow has overspread the region, I have had to re-issue the Advisory for Grand Isle County Vermont, and Clinton, and Essex Counties in New York. Infact some of the moderate snow has made it into Southern Franklin County NY as well. With light snow all the way into St. Lawrence County. The Warnings I did have to change, as the heavy snow was not as widespread as thought, due to the dry slot, and the surface low pulling away from the upper level low faster then expected. The only place with a warning left in place by JRWeather is the Western Slopes of the Green Mountains. The National Weather Service in Burlington has already done the same thing, but the National Weather Service in Albany still feels Warning criteria snow will fall across Bennington, and Windham Counties in Southern Vermont, so they remain under a Warning by the NWS. I don't see Warning criteria snow being widespread enough down there to warrant a warning. So I am still calling for 6-9 inches in the Warning area, and 3-6 inches in the Advisory area. Make sure to view the maps below, to see what County/ portion of a county you fall under.
    Radar is currently showing moderate snow heavy at times across the region. The southern edge of the snow was near the Southern portions of the NJ/PA border, however over the past hour or so, some more precipitation has developed down near Washington DC, this precipitation has grown in areal coverage and intensity, and appears to be moving to the North-Northeast. This will have to be watched, as this could prolong the snowfall for our region, depending on whether or not it will stay intact or not. Eitherway this storm is one that will continue to be watched for any further changes. Stay tuned!
