.DISCUSSION...
As of 218 PM EDT Tuesday...
KEY MESSAGE 1: Period of dry weather continues for the north
country as large ridge of surface high pressure nudges into our
area out of Canada. Lots of dry air remains in place, and winds
are out of the north following the passage of a weak surface
boundary this morning. After afternoon ranging highs ranging
through the 50s today, minimum temperatures overnight will dip
into the mid 20s to mid 30s, warmest along Lake Champlain where
the temperatures will be closer to 40. Ideal radiational cooling
conditions, will also lead to some patchy fog developing in the
typically fog prone spots. Surface high will retreat to the
north and east of our area tomorrow as a Nor`easter meanders off
the east coast. Wednesday night a weak cold front will cross
our area, bringing colder conditions for Thursday and Friday to
close out the work week, with another surface ridge of high
pressure building into our area from the northwest. Maximum
temperatures on Friday will struggle to get out of the 40s.
Winds will also be brisk out of the north, especially on
Thursday.
KEY MESSAGE 2: A classic stretch of fall weather will continue
this weekend and into the beginning of next week. Surface high
pressure will be centered almost directly overhead over the
weekend, leading to clear skies, light winds and highs in the
50s. Most mornings will be frosty with lows in the 20s and 30s.
A moisture starved cold front moves through Monday and Monday
night and while a brief sprinkle or mountain flurry is possible
during its passage, it will be pretty much completely dry.
Temperatures rise to around 60 Monday, before highs drop back
into the 50s and potentially upper 40s for Tuesday.

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
Through 18Z Wednesday...VFR conditions will mostly prevail for
the next 24 hours. The one exception would be late tonight when
some patchy fog will develop. A brief period of IFR visibility
is possible at MPV, SLK and EFK, with a probability of
occurrence probably around 40 percent. Winds will generally be
northerly today, with gusts between 5-15 KT. Winds will go
light/variable/terrain driven tonight and remain that way
through tomorrow.
