Area Forecast Discussion
National Weather Service Burlington VT
746 PM EDT Wed May 29 2024

.SYNOPSIS...
A dry weather pattern is becoming established over Vermont and
northern New York. After some cooler conditions tonight through
Friday morning, a steady warming trend will begin. Fantastic weekend
weather is expected. Localized to isolated showers activity will
return with the work week as temperatures climb into the 80s during
the afternoon.

.NEAR TERM /THROUGH THURSDAY NIGHT/...
-- Changed Discussion --
As of 726 PM EDT Wednesday...No big changes for the evening
update. Have updated forecast to reflect current satellite
trends. No precipitation is expected. Previous discussion
follows.

Dry air is slowly winning out. Some stratocumulus remains, and
these should dissipate with the loss of daytime heating.
Although there will be a few mid to high clouds streaming in
from a vort northeast from the Ohio River Valley. This poses two
questions for tonight. How low can we go in radiational cooling
limbo, and can we get some fog? The proverbial bar is set at
300-500 ft above the ground where 10 to 15 knot winds should
promote some level of mixing. Based on how cool this airmass is
following the warm, damp air mass and calm winds, decided to
lean on the colder side and add fog in the favorable river
valleys. It will be cold enough in the hollows of the
Adirondacks that some patchy frost could develop, but it appears
quite localized. Probabilistic data suggests there is a low
chance this could impact the Northeast Kingdom as well if they
radiate out better than currently forecast. We`ll see if SLK can
hit 32, but currently have 33 at the Adirondack Airport.

Elsewhere, mainly 40s are expected, followed by warming into the mid
60s to lower 70s once again. It should be another gorgeous day with
a steady north wind around 10 mph on Thursday. Thursday night looks
like a repeat performance with 10 to 15 knot winds at 300-500 ft
above the ground. So we`ll see how well our weather stations do in
their game of radiational cooling limbo tonight as a persistence
forecast will likely work best. Though it may be a degree or
two warmer. So once again, some patchy frost will be possible in
cold hollows of the Adirondacks along with river valley fog as
the sun rises Friday.

.SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/...
As of 313 PM EDT Wednesday...Friday is shaping up to be a beautiful
day as upper level ridging and surface high pressure build over the
region, with some sunshine and dry weather expected to round out the
month of May. Daytime highs will be pleasant, with temperatures in
the upper 60s into the lower 70s and dewpoints maxing out in the
40s. Heading into the overnight hours, low temperatures will drop
into 40s and low 50s, which is near climatological normals for this
time of year.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
As of 313 PM EDT Wednesday...Upper level ridging and surface high
pressure will remain across the region heading into the weekend,
with quiet stretch of weather to start off June. The ridge will
begin to break down towards the middle of next week, with increasing
chances for showers by Tuesday with a warm front lifting through the
region. Temperatures will gradually warm into early next week, with
high temperatures climbing into the upper 70s to mid 80s by Tuesday.
Overnight lows will also see a warming trend, with temperatures in
the 40s/50s over the weekend climbing into the 60s by midweek.

.AVIATION /00Z THURSDAY THROUGH MONDAY/...
-- Changed Discussion --
Through 00Z Friday...Skies will become mostly clear overnight.
Light to terrain driven flow is expected tonight. Some fog may
develop in river valleys, but 10-15 knot winds at 300-500 ft agl
may prevent formation, and for now have just noted some BR at
EFK which I believe has the best chance of any fog development.
North to northwest winds increase to 6 to 10 knots beyond 13z
with mid clouds around 7000-12000 ft agl, mainly in southern
Vermont.

Outlook...

Thursday Night: VFR. NO SIG WX.
Friday: VFR. NO SIG WX.
Friday Night: VFR. NO SIG WX.
Saturday: VFR. NO SIG WX.
Saturday Night: VFR. NO SIG WX.
Sunday: VFR. NO SIG WX.
Sunday Night: VFR. NO SIG WX.
Monday: VFR. NO SIG WX.
