Snow To Last A Bit Longer Across Portions Of Vermont; Winter Storm Warnings Remain In Effect Until 3AM Now

Local Update...
   JRWeather Winter Storm Warning In Effect Until 3AM Thursday...


JRWeather WINTER STORM WARNING
     JRWeather Continues The Winter Storm Warning for Orleans, Essex, Lamoille, Washington, Orange, Caledonia, Eastern Franklin, and Eastern Chittenden Counties In Vermont Until 3AM Thursday.

     JRWeather has extended the Winter Storm Warning for a few more hours across the Western Slopes of the Green Mountains, and portions of Central, and Northeastern Vermont. The Winter Storm Warning is no longer in effect for the Champlain Valley, Northern New York, or Southern Vermont.

     An area of convergence, and upslope enhanced snow continues across the Western slopes of the Green Mountains in Eastern Franklin, and Eastern Chittenden Counties, radar indicates that some of this could be falling moderately. This area of snow should continue to move east. An additional 1-3 inches of snow with locally higher amounts will fall across the Warning area by 3AM. The highest additional accumulations will likely be across Lamoille, Washington, Eastern Franklin, and Eastern Chittenden Counties. Total snow accumulations in the Warning area will range from 10-14 inches, with locally higher amounts of up to 18 inches possible, especially along the spine of the Green Mountains in Northern Vermont.

     Of additional concern is the fact that winds have increased into the 10-15MPH range with gusts in the 25-30MPH range. Sustained wind speeds should remain where there are but isolated gusts of up to 40MPH is possible, especially along the western slopes of the Green Mountains, and higher elevations. This will cause areas of blowing and drifting snow, resulting in visibilities to a quarter mile or perhaps less at times. The winds should diminish by mid-morning.

     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 better by the morning commute Thursday, although roads will still be very slick, so use caution while driving.


DISCUSSION
     Well a little bit of a surprise you could say. Although with a Northwest wind and a departing storm, I guess I should have seen it coming. Snow looks to last a bit longer along the Western Slopes of the Green Mountain of Northern Vermont, and all across much of Northeastern Vermont. Northwest winds have increased aiding in a moist flow into the Western Slopes of the Green Mountains, this has resulted in continued snow, even moderate at times. This should diminish though as moisture thins out. Snow should have come to an end by 3AM. The most concentrated area of snow is across Lamoille, Washington, Eastern Franklin, and Eastern Chittenden Counties. Snow will continue to move east across Northeastern Vermont, with additional totals of 1-3 inches, with locally higher amounts especially along the Western Slopes of the Northern Green Mountains. Storm totals across the Western Slopes look to range from 10-14 inches. I raised the bottom number a tad, but they still fit in the 8-14 which is widespread for the entire region, so the maps wont show an area of 10-14 inches. I also wouldn't be surprised to see some isolated accumulations of up around 18 inches. But with big storms like this, that's not really uncommon. Winds have also increased area wide resulting in some blowing and drifting snow. So if you have to travel anytime between now, and mid-morning use extreme caution, as roads will be snow covered, and visibilities will be reduced in areas of blowing, and drifting snow.
