.DISCUSSION...
.UPDATE...Noticed based on latest obs that temperatures were
several degrees off the NBM. Therefore, made updates to the
hourly temperatures, dewpoints, and minimum temperature forecast
for tonight. Given the favored radiational cooling set up for
tonight with high pressure moving overhead; little wind; much
lower dewpoints; and anticipation for current clear skies to
persist, lows should be able to radiate down to the mid/;upper
40s across high terrain and low to mid 50s in the valleys. All
else remains on track with additional details below.

.PREVIOUS DISCUSSION...
Surface high pressure overhead continues through Saturday night
bringing dry conditions to eastern New York and western New
England. Temperatures remain seasonal and comfortable as highs
tomorrow range in the 60s for higher terrain locations to the
mid 80s in valleys. Low temperatures tonight into tomorrow
morning are going to be cool with lows ranging in the 40s across
higher terrain locations and in the 50s elsewhere.

By Saturday night, surface high pressure heads east and high
resolution forecast model guidance is supporting rain showers
and a few thunderstorms to move through associated with a low
pressure system moving through the Great Lakes region during the
very early morning hours Sunday. There is some shifting of the
low pressure system with latest forecast model guidance having
it head further north for Saturday night, so dry conditions are
favored to continue through at least midnight for eastern New
York and western New England. For locations north and west of
Albany, rain showers have the greatest chances (greater than 50
percent) of occurring with a few rumbles of thunder between
midnight and 6 AM at this forecast time. Chances for
precipitation (40-60%) increase Sunday afternoon ahead of a cold
front across eastern New York and western New England. Precipitation
amounts are forecasted by latest National Blend of Model data
to range between 0.1 inches and 0.25 inches, but could be higher
with heavier downpours from thunderstorms. Primary concerns
with any developed thunderstorm Sunday is lightning, heavy
downpours, and gusty winds. By Sunday night, dry and breezy
conditions return behind the cold front. Surface high pressure
continues overhead through Tuesday bringing dry conditions.

Seasonal temperatures continue through the weekend into the
beginning of next week with highs ranging in the 70s and low to mid
80s. Low chances of precipitation (less than 30%) for beyond
Wednesday as ensemble forecast models and National Blend of Models
probabilistic guidance supports a variety of weather conditions as
we could see either dry conditions or afternoon rain shower activity
due to upper level troughing. Low temperatures overnight into the
morning hours range in the 50s and 60s. Locations in the Adirondacks
could range in the 40s for Monday morning. Towards midweek into the
end of next week, hot afternoon temperatures and humid conditions
could return with temperatures ranging in the 80s and low 90s.
Latest National Blend of Models 4.3 data suggests high temperatures
for Thursday greater than 90 degrees across valley locations between
50 and 65 percent.

.AVIATION /05Z SATURDAY THROUGH WEDNESDAY/...
VFR conditions are expected to prevail at area TAF sites
throughout the forecast period. The main exception will be GFL
which will have TEMPO IFR visibility restrictions due to patchy
fog through the early morning hours Saturday. Lower ceilings are
forecast to build into the area late Saturday evening, but
MVFR/IFR restrictions look most likely to occur after 06Z
Sunday.

Winds will remain light out of the south to southwest with
sustained speeds under 10 kt.
