409 am EDT sun Sep 15 2019
high pressure is beginning to build into the north country.
Mostly dry conditions will prevail for the next several days.
Highs will be near seasonal norms and then gradually become
above normal towards the end of the week.
Near term /through Monday/...
as of 404 am EDT Sunday...conditions are quiet with mostly clear
skies and some fog across the Connecticut River valley and far
southern Champlain Valley. Pockets of low stratus can be seen
blossoming towards Saranac Lake as well. Temperatures have fallen
into the 50s this evening, and should fall at least a couple more
degrees before sunrise.
A compact upper shortwave advects into the north country on
Sunday, but better dynamics and moisture remains south of the
area. Some virga will be possible as the the shortwave pushes
east. Otherwise, we will be partly to mostly cloudy with highs
near in the mid 60s to lower 70s. Overnight lows should cool
into the mid 40s to lower 50s.
Another upper shortwave pushes south into our area Monday
morning. Similar to Sunday, lack of moisture and dynamical
support, along with strengthening surface high pressure should
keep precipitation to a minimum. Best chances for very light
showers will be across the Adirondacks and southern Vermont.
Otherwise, another dry day with highs in the 60s.
Short term /Monday night through Tuesday/...
as of 404 am EDT Sunday...a northerly low-level flow sets up Monday
night into Tuesday with cold advection allowing 850 temps to fall to
3-5c early Tuesday before moderating back to 5-7c especially west of
The Greens Tuesday afternoon. With the cold pocket at 850 and north
to northwest orographic lift expecting a decent amount of fair
weather stratocu in the short term, gradually lessening except a bit
more persistent in the nek and eastern Vermont as the cold pocket
gradually moves east and high pressure drifts southward through the
region. All in all there should less clouds west and more east and
temperatures will follow suit with lows mainly in the 40s and highs
in the 60s.
Long term /Tuesday night through Saturday/...
as of 404 am EDT Sunday...the long term period looks mostly sunny and
dry with temperatures warming above normal by Wed through Sat.
Our weather pattern will be dominated by an amplifying upper level
ridge aloft to our west with a mainly dry northwest flow over our
region. High pressure at the surface Tue slowly drifts over our
region then off to our south and east by Thu and Fri allowing
temperatures to moderate right into Saturday. 850 temps climb from
about 7c on Wed to 10c on Thu to 13c on Fri/Sat.
Normal high temps will be in the upper 60s next week so we'll be
looking for daytime highs in the lower 70s Wed, mid 70s Thu, and
upper 70s to near 80 by Fri/Sat. Lows will be coolish with lots of
40s and a few 30s Wed morning but climbing a few degrees each
morning to be in the 50s area wide by Sat.
