Strong Winds For Friday

Local Update...
   Strong Wind Gusts Of Up To 50MPH Expected Friday...

JRWeather WIND ADVISORY
     JRWeather Has Issued A Wind Advisory For Grand Isle, Franklin, Chittenden, Addison, Rutland, and Bennington Counties in Vermont and All of Northern Northern New York From 5AM Friday Morning Until 5PM Friday Evening.

     A low pressure system moving through the great lakes region, and its associated cold front, will be responsible for bringing strong winds to the region Friday. Winds will increase from the South-Southwest during the early morning hours. Sustained winds will be in the 15-30MPH range with gusts up to 50MPH, throughout the day. Winds will begin diminishing as precipitation begins falling, due to the cold front. Winds may once again pick up briefly, when the front pushes through later Friday Night.

     A Wind Advisory is issued when sustained winds of 30-39MPH or gusts up to 54MPH are expected. Stay tuned for further updates.


DISCUSSION
     Looks like it will be a windy day tomorrow. A low pressure system will be moving East-Northeast from the Great Lakes region, with a tight pressure gradient, and associated cold front, helping to mix down the winds. The strongest winds should be during the afternoon hours, before the rain falls. The winds will be out of the South-Southwest. These Southerly winds usual have a significant impact on the Champlain Valley, as the Southerly winds like to funnel up the North-South oriented Valley. The St. Lawrence Valley is another Valley that will likely see strong winds as they get downsloped by the Adirondack mountains, and with the winds being somewhat Southwest, they like to funnel up the Southwest to Northeast Oriented Valley. These areas will likely see the strongest wind gusts, along with any Southwest facing slopes in the Northern Adirondacks, and the Green Mountains. Eastern Vermont, will likely see gusts up to 40MPH at times, but that's not enough to Warrant an Advisory. Stay tuned!
