AREA FORECAST DISCUSSION
National Weather Service Albany NY
925 AM EDT Fri May 31 2024

.SYNOPSIS...
Clear skies and light winds will yield seasonably cool
temperatures across the region this morning, before moderating
through the day. Nearby surface high pressure will see gusty
west to northwest winds this afternoon, with otherwise continued
fair weather into the weekend. Temperatures will trend above
normal into early next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
.UPDATE...As of 920 AM EDT, patchy high clouds continue to
stream southward into the SW Adirondacks and Mohawk Valley, and
expect a general uptick in high clouds through the morning
elsewhere, especially for areas near and east of the Hudson
River. Otherwise, forecast remains on track with afternoon
temperatures warming into the lower/mid 70s for most valley
areas, and 65-70 across higher terrain areas. Northwest winds
will increase this afternoon as deeper mixing develops, with
some gusts up to 20-25 mph possible. Previous discussion
below...

.PREV DISCUSSION [0345 AM EDT]...Upper ridging and surface
high pressure approaching from the west will bring continued
fair weather through tonight. With light winds beneath clearing
skies, much of the region is in for a cool morning, with areas
above 1500 ft elevation starting the day in the upper 30s, while
lower elevation locales begin in the low to mid 40s. Steep low-
level lapse rates up to 800-850 hPa developing by this afternoon
will allow for some stronger west to northwest winds to mix
down to the surface, potentially gusting as high as 20-25 mph
along the Mohawk Valley, across the Capital District, and in the
higher terrain of the eastern Catskills and Berkshires. Some
higher clouds may pass over the region through the afternoon,
with otherwise mostly sunny skies and temperatures moderating to
near normal values, reaching afternoon highs in the 60s in
higher terrain and low to mid 70s at lower elevations. Another
night of largely clear skies and light winds will again see
efficient radiative cooling, resulting in overnight lows in the
40s for most of the region.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
Pleasant weather continued into the weekend as upper ridging
approaches from the west on Saturday and passes overhead on
Saturday night. Temperatures reach a few degrees above normal
beneath mostly sunny skies through the afternoon, reaching highs
in the upper 60s to mid 70s in high terrain and upper 70s to mid
80s at lower elevations. Mid to high clouds begun to increase
from the west into Saturday evening and night, as temperatures
fall to overnight lows in the upper 40s to mid 50s.

On Sunday, the upper ridge will begin to stretch out as it
becomes squeezed between upper troughing over Hudson Bay to the
west and a deep upper low off the Canadian Maritimes to the
east. An upper shortwave riding up the western flank of the
ridge will weaken somewhat and begin to slow as it approaches,
with scattered rain showers ahead of a surface frontal boundary
reaching into the region Sunday afternoon and evening. Enhanced
cloud cover and spotty showers may knock a few degrees off of
temperatures compared to Saturday, with afternoon highs in the
mid 60s to upper 70s expected. Higher surface dewpoints
additionally limit overnight cooling, with lows Sunday night in
the 50s across the region.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
An upper level shortwave looks to depart the region to the east on
Monday as upper-level ridging attempts to return into midweek. High
pressure will dive southward from Canada and set up along or just
off the New England coast. This high should provide enough
subsidence for mainly dry weather, but some pop up showers and
thunderstorms cannot be ruled out either day, but looks more on the
isolated side. NBM PoPs continue to look a bit too aggressive for
Tuesday and Wednesday, especially compared to the latest
deterministic models which show a drier trend, so trimmed them back
slightly, but maintained some slight chance to low chance for now.
The better, more widespread, rain chances look to be toward the end
of the week as an upper-level trough/low tracks eastward from the
central CONUS, sending a cold front toward our area. Overall
forecaster confidence on the long term period remains low to
moderate as run-to-run model consistency during this period remains
poor.

Highs will be mainly in the 70s/80s each day with lows in the 50s to
lower 60s.

&&

.AVIATION /13Z FRIDAY THROUGH TUESDAY/...
Through 12z/Sat...VFR conditions are expected through the upcoming
TAF period at all sites with just some mid and high clouds at times
as high pressure builds in to our west. The air mass will be dry
enough to prevent any fog formation.

Wind will become northwesterly at 10-15 kt with gusts to around 20
kt today. Wind will decrease to less than 10 kt early this evening,
then calm overnight.

Outlook...

Saturday Night: No Operational Impact. NO SIG WX.
Sunday: Low Operational Impact. Slight Chance of SHRA.
Sunday Night: Low Operational Impact. Slight Chance of SHRA.
Monday: No Operational Impact. NO SIG WX.
Monday Night: No Operational Impact. NO SIG WX.
Tuesday: Low Operational Impact. Slight Chance of SHRA.
Tuesday Night: Low Operational Impact. Slight Chance of SHRA...TSRA.

&&

.FIRE WEATHER...
Today, minimum RH values drop to 30 to 40% in the afternoon
while gusty west-northwest winds may reach 20 mph. Fire weather
concerns nonetheless remain low as substantial rainfall has been
observed across the region within the past 5-7 days.
