From BTV:
The low level jet will peak during the
morning hours, most likely between 4 AM and 9 AM, which will likely
be so strong that it will break through the mountain barrier
regardless of stability. As a result, dangerous wind gusts will
occur well away from the higher terrain. Looking at model data
reveals very strong 925 east-southeast winds increasing into the 70
to perhaps 90 knot range along the corridor from Essex Junction to
Middlebury, supporting peak winds in excess of 65 MPH. Multiple long-
time forecasters have not seen winds at this pressure level at this
magnitude in our region.
