The National Weather Service in Burlington continues pretty much all the same alerts as the previous post, except they have dropped the Winter Storm Warning across Vermont, down to a Winter Weather Advisory. I have also changed the alerts some, and cancelled the Blizzard Waring for some areas. I have also decreased accumulations across some areas.
Previous post below...
Alert Details:
The National Weather Service in Burlington, VT has issued a Winter Storm Warning for the higher elevations of South Central, Vermont, and The eastern slopes of the Northern Adirondack Mountains for the potential of 6-8 inches of snow. A Winter Weather Advisory is in effect for North Central, and Central Vermont, as Well as the St. Lawrence Valley for the potential of 4-6 inches of snow. A High Wind Warning is in effect for the Western Slopes of the Green mountains, The Southern Champlain Valley, and Eastern Vermont for strong to damaging winds of 25-35MPH with gusts 55-65MPH. A Wind Advisory is in effect for the Northern Adirondacks, and the St. Lawrence Valley for sustained winds of 20-30MPH with gusts up to 50MPH.
The National Weather Service in Albany, NY has issued a Winter Storm Warning for Bennington, and Western Windham County for the potential of 6-16 inches of snow across the higher elevations. A High Wind Warning is in effect for all of Bennington, and Windham Counties for sustained winds of 30-40MPH with gusts 60-75MPH.
Champlain Valley Weather has issued a Blizzard Warning for much of Northern New York, and portions of Central, and Southern Vermont for the potential of 6-12 inches of snow across the higher elevations, with sustained winds in the 25-40MPH range with gusts in the 60-70MPH range, locally higher gusts could occur on east facing slopes, and in mountain gaps. A High Wind Warning is in effect for North Central, Central, and Northeastern Vermont for sustained winds of 25-40MPH with gusts in the 60-70MPH range, locally higher gusts could occur across east facing slopes and in mountains gaps. A Wind Advisory is in effect for the Champlain Valley, for sustained winds of 15-25MPH with gusts in the 45-50MPH range.
Champlain Valley Weather Discussion:
A complex storm system is evolving across the area. Mainly light precipitation has been falling across the area, with mainly snow across Northern New York, and mainly rain across Vermont, with some isolated pockets of snow in the highest of elevations. After looking at new model data, and seeing this storm come together, I had to cancel the Blizzard Warning for much of Northern Vermont, and I have Canceled the Blizzard Watch for the Champlain Valley, and Southern Connecticut River Valley, these areas will see primarily rain, and/ or low precipitation amounts.
For the areas under a Blizzard Warning, you can expect to see rain change over to snow, and be heavy at times over night. Winds will increase and be at there strongest during the overnight. By Friday evening snow will have accumulated 6-12 inches across elevations primarily above 1000 feet, the only exception to the elevation is the St. Lawrence Valley where just enough cold air should hold on and produce all snow. Across the Champlain Valley, and Areas no longer under a Winter alert can expect primarily light to occasionally moderate rain, there is a slight change of a heavier burst of rain, but that's not expected to be widespread. Precipitation amounts across these areas will likely be light due to shaddowing from the mountains. Snow accumulations will range from a Trace to 2 inches in the Valley's to up to 3 or 4 inches across the higher terrain, of North Central, and Northeast Vermont.
Once again the winds will be the strongest during the overnight. I am very concerned for eastern facing slopes, and mountain gap locations. Low pressure already down to 987mb will continue to strengthen rapidly, and down into the 970-975mb range. Some models show this getting down to around 968mb. With a low that strong, I wouldn't be surprised if some wind gusts were well in excess of 70MPH, especially in favored gap locations, and eastern facing slopes. Heavy wet snow combined with winds this strong, spells major trouble. There still remains over 9,000 people without power across Vermont, from yesterdays storm. It would be strongly recommended to prepare for power outages, and wind damage if you live in an area under a High Wind Warning or a Blizzard Warning. Stay tuned for further updates on this dangerous developing weather situation.
