Area Forecast Discussion
National Weather Service Burlington VT
1025 AM EDT Sat Jun 15 2024

.SYNOPSIS...
A gorgeous weekend is in store with high temperatures in the 60s and
70s and low humidity. This will be short-lived as a long-duration
heat event moves in next week. Combined with high humidity, it
will cause heat indexes to approach 100 degrees. Warm overnight
lows will prevent any nighttime relief so heat related impacts
will occur.

&&

.NEAR TERM /THROUGH SUNDAY/...
As of 1025 AM EDT Saturday...No changes needed to the forecast
for today. As surface high pressure shifts over the region
abundant sunshine is expected, and even the few-scattered fair
weather cumulus forming this morning over some of the higher
terrain should dissipate this afternoon as 850mb moisture
decreases further. Some decent mixing will be around though,
especially across eastern Vermont where northwesterly winds will
gust through the afternoon upwards of 25 mph. Highs remain on
track to top out about 6-8 degrees below normal in the mid 60s
north to low 70s south.

For tonight into tomorrow, strong radiational cooling will drive
temperatures into the 40s. Parts of the Northeast Kingdom and
Adirondacks are likely to fall down into the 30s. Saranac Lake is
forecast to reach 33 at present, coming close to a daily record of
32 early Sunday morning. Some patchy frost has been applied, mostly
in the northern Adirondacks. Sunday should be very pleasant with dry
weather and light winds. High temperatures will generally be in the
70s.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH MONDAY/...
As of 325 AM EDT Saturday...Dry conditions continue through Sunday
night with heights aloft and cloud cover increasing. A weak trough
will be approaching the North Country, but low level high pressure
will be building northward at the same time. The result will be much
warmer overnight temperatures with lows in the upper 50s to around
60 degrees for most spots. As the trough passes north in Canada
Monday, a few showers will be possible, but 1000-500mb thickness
will also be increasing. While we can`t rule a very rare rumble of
thunder in the early afternoon, the most notable conditions Monday
will be surging high temperatures from around 80 degrees into the
mid 80s. Warming temperatures aloft will likely cap convection late
in the afternoon/evening.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
As of 325 AM EDT Saturday...Models continue to favor an anomalously
strong ridge to build over the region Tuesday through Thursday with
high temperatures above 90 degrees. If the ECMWF has its way,
temperatures could eclipse 100 degrees Wednesday. However, the
consensus is marginally "cooler" in the mid/upper 90s. Coupled with
dew points in the mid/upper 60s to almost 70 degrees, and WBGT will
climb and conditions will "feel" around 100 degrees. This is notable
for the region with Heat Risk in the Major/Extreme categories for
most locations. Plan on dangerous heat next week. Some ways to
mitigate these hazardous conditions include limiting outdoor
activities, knowing where your local cooling centers will be -
especially if you have no AC at home - and staying hydrated.
Overnight temperatures will not provide much relief for most
locations with lows ranging in the upper 60s to around 70 degrees.
Given the heat and higher dew points, showers and a few
thunderstorms may occur. Relief from 90+ temperatures may come by
the weekend, but temperatures will still be running warmer than
seasonal averages.

.AVIATION /15Z SATURDAY THROUGH WEDNESDAY/...
Through 12Z Sunday...Mainly VFR the next 24 hours. Skies
trending clear over the next 3 to 6 hours. North to northwest
