Good AFD from BTV…
A cold front will sweep through the area Friday night sharply
lowering temperatures 10 to 15 degrees from Friday evening to
Saturday morning. Temperatures will likely dip below freezing for
most if not all locations across the area with only those near Lake
Champlain and immediately near the St. Lawrence River staying above
freezing. As temperatures fall, snow levels during the day Saturday
will also lower to 500-1000ft agl, with a transition to snow above
1500ft agl, and a rain, wet snow mix, in elevations between 1000-
1500ft agl. A few mixed in flurries cannot be ruled our even in the
Champlain Valley, though temperatures will be marginal in the mid to
upper 30s. Some snowliage appears likely with ensembles denoting
nearly 100% chances for purely snowfall in the Adirondacks and
Northeast Kingdom.
Rain and snow showers will taper off Saturday evening as the system
pulls away to the northeast. 850 mb temperatures Saturday night will
be remarkably cold for this time of year in the -9 to -11C range
Saturday night supporting temperatures in the 20s for most of the
area, including the entire Champlain Valley. Pockets of teens will
be possible in the coldest hollows of the Adirondacks and Northeast
Kingdom as surface temperatures anomalies will be 10 degrees below
normal. Temperatures will slowly moderate back towards seasonable
normals to start next week.
