Special Weather Statement, NWS Albany, NY

AREA FORECAST DISCUSSION
National Weather Service Albany NY
424 PM EDT Wed Aug 11 2021

.SYNOPSIS...
Dangerous heat conditions will continue through Friday with
heat index values exceeding 100 in many valley locations.
Isolated to scattered showers and thunderstorms will occur each
day with the most widespread chances in the afternoon into early
evening hours. A more seasonable airmass will be ushered in
over the weekend after the passage of a cold front.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
Hot and humid with dangerous heat conditions occurring with
heat advisory remaining in effect into early this evening (8 pm)
for most of the forecast area. Milder and muggier tonight with
lows only dropping into the lower to mid 70s with upper 60s
occurring above mainly 1500 feet.

Isolated to scattered convection developed across the local
area as another short wave approaches during peak heating. Have
plenty of instability, however forcing is rather weak. There is
the threat for isolated severe into the evening. With coverage
have chance pops well into the evening. With the passage of the
short wave and loss of heating threat for storms will diminish.
Lots of activity upstream. Guidance indicates it should stay to
the west of our area.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/...
Extreme heat and humidity will significantly increase the
potential for heat related illnesses Thursday.

Excessive Heat Warning has been posted for up the Hudson River
from the Poughkeepsie area northward up to the Saratoga area
with heat advisory in effect for the rest of the local area
excluding the northern Herkimer and Hamilton counties. The
warning and advisory are in effect from 10 am to 8 pm Thursday.
Looking highs in the lower to mid 90s below mainly 1000 feet
with dew points in the lower to mid 70s resulting in heat index
values up to around 105. Above 1000 feet highs in the 80s with
dew points in the upper 60s to lower 70s resulting in heat index
values up to around 100.

Convection is expected to develop across the area during the
afternoon with peaking heating as yet another short wave
approaches. Mid-level flow and shear are expected to be limited,
however instability will be greater and so will be mid-level
lapse rates so coverage of the storms is expected to be greater
than the past couple days with storms being able to organize.

Another day with dangerous heat conditions Friday; not quite as
warm as Thursday but with similar dew points. The Excessive
Heat Watch remains in effect for the mid-Hudson Valley. It may
need to be upgraded to a warning. A heat advisory will be needed
for much of the local area again.

More convection Friday as the cold front moves closer and we
see some height falls later in the day into the night as a short
wave rotates about the upper level low over Hudson Bay.

All storms will be capable of producing heavy rainfall with some
minor flooding of urban, poor drainage and low lying areas and
isolated flash flooding possible.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
The last stage of the passing of the cold front occurs on Saturday
with isolated to scattered showers and storms from the Capital
Region and points north and west and slightly better coverage east
and south of the Capital Region. Highs Saturday in the lower to mid
80s with 70s in higher terrain.

Slow and gradual ridging building into the region Sunday through
Wednesday with some questions on whether northern stream upper
energy drops south out of SE Canada brushing through New England
around the Tuesday afternoon through Wednesday time frame. That will
depend on how far east the upper ridging builds toward our region.
There are some considerable differences in sources of guidance, so
just including isolated to widely scattered showers and storms for
Tuesday afternoon through Wednesday.

Highs Sunday through Tuesday in the upper 70s to lower 80s with
cooler in higher terrain. Highs Wednesday around 80 to mid 80s with
70s higher terrain.

&&

.AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
VFR conditions exist at the terminals this afternoon with some
diurnal cu and high cirrus around. Low confidence with respect to
convective potential at this time. Most probable time frame is
21Z.11 through 03Z.12 for scattered showers and thunderstorms to
develop, but whether anything develops is unclear at this time, and
even if there is development, coverage is not expected to be
widespread. Used VCSH wording due to low confidence, but an isolated
TS cannot be ruled out.

Overnight, VFR conditions continue. One or more convective complexes
will be approaching from the west, but current thinking is that they
will dissipate before reaching the local area. Some fog cannot be
ruled out at KGFL/KPSF overnight due to the humid airmass. VFR
conditions continue into early Thursday afternoon, with any
convective development not likely until after the end of the 18Z TAF
cycle.

Winds will generally be from the south to southwest at 5 to 10 kt
for the rest of the day, becoming 5 kt or less tonight.

Outlook...

Thursday Night: Moderate Operational Impact. Chance of SHRA...TSRA.
Friday: Moderate Operational Impact. Chance of SHRA...TSRA.

.FIRE WEATHER...
Hot and humid conditions will continue through Friday. Isolated
to scattered showers and thunderstorms will occur each day with
the most widespread chances in the afternoon into early
evening hours. A more seasonable airmass will be ushered in
over the weekend after the passage of a cold front.

&&

.HYDROLOGY...
Hot and humid conditions through Friday. Isolated to scattered
showers and thunderstorms will occur each day with the most
widespread chances in the afternoon into early evening hours.
Storms will be capable of producing heavy rainfall. With the
expected coverage of storms widespread hydro issues are not
expected, however some minor flooding of urban, poor drainage
and low lying areas and isolated flash flooding possible.
