JRWeather Winter Weather Advisory In Effect From 10PM Tonight To 10PM Wednesday; JRWeather High Wind Watch In Effect From 7AM Wednesday To 10AM Thursday...
JRWeather WINTER WEATHER ADVISORY
JRWeather has continues the Winter Weather Advisory for Orleans, Caledonia, Essex, Lamoille, Washington, Orange, Eastern Franklin, Easter Chittenden, and Eastern Addison Counties
in Vermont, and St. Lawrence, Franklin, Western Clinton, and Western Essex Counties in New York.
A low pressure system moving Northeast and into the Great Lakes region through Christmas Eve, will bring some wintry precipitation to the area. It should start as all snow for the entire region late tonight, and slowly change over to sleet, and then to freezing rain, and to plain rain in some spots by Wednesday Afternoon. By late Wednesday Night any remaining showery precipitation should change back to a sleet/snow mix and eventually all snow. No to very light additional accumulation is expected after 10PM Wednesday night. Total snow accumulations of 2-5 inches, and total ice accumulations of around a tenth to locally a quarter inch can be expected in the Advisory area. The most significant ice accumulations will occur across the sheltered valley's in Northeastern Vermont, and the St. Lawrence Valley in Northern New York.
A Winter Weather Advisory is issued when significant but not severe winter weather is expected. In this case the winter weather advisory is for light to moderate snow, and ice accumulations. Holiday travel will be impacted by this storm, but not severely. Roads will become snow, and ice covered but not enough to make travel impossible. Drive cautiously, and defensively, and leave extra time to reach your destination.
JRWeather HIGH WIND WATCH
JRWeather has issued a High Wind Watch for Bennington, Lamoille, Washington, Eastern Franlin, Eastern Chittenden, Eastern Addison, Eastern Rutland, and Western Windham Counties in Vermont From 7AM Wednesday to 10AM Thursday.
A strengthening low pressure system over the Midwest region, combined with a high pressure system over the Atlantic will result in a tightening pressure gradient. This will result in the potential of strong to damaging winds for the Western Slopes of the Green Mountain from Northern Vermont, all the way to Southern Vermont. The potential exists for winds of 20-30MPH with gusts in excess of 55MPH. Winds of this magnitude are strong enough to cause small trees, and large limbs to break, resulting in the potential for power outages, of additional concern, since its the holiday season, holiday decorations stand the threat of being damaged, and blown around. It is recommended to secure loose objects, as well as holiday decorations so damage will be minimal if any.
Winds should diminish by Thursday afternoon, ending the high wind threat. A High Wind Watch is issued when there is the potential for damaging sustained winds of 40MPH or greater, and/ or Wind gusts of 55MPH or greater. Stay tuned for further updates.
Discussion
As you can see from above, Winter, and Wind Alerts have been issued for much of the region. Not mentioned above is the National Weather Service has issued a Winter Weather Advisory for the entire area.
It looks like the entire region will see a wintry mix, but the most significant will be across Northern New York, and Northeastern Vermont. I have not included the Champlain Valley of Vermont in the Winter Weather Advisory due to the fact the southerly flow will help temperatures rise rapidly, and exclude any significant freezing rain. Although a couple inches of a snow/ sleet mixture is expected. This same situation applies for Southern Vermont as well. Of another concern is the potential for strong to damaging winds across the entire region. Damaging winds will most likely occur along the Western slopes of the Green mountains, from the Canadian border, south to the Massachusetts border, thus I have issued a High Wind Watch for potential gusts of 55MPH or higher into Thursday afternoon. The rest of the region though will likely see strong winds in the 15-30MPH range with occasional gusts in the 45-50MPH range. I will likely issue a Wind Advisory for the entire region later tonight or tomorrow morning, and possibly upgrade the Watch to a Warning, at the same time. Updated maps are below. Stay tuned!
