AREA FORECAST DISCUSSION
National Weather Service Albany NY
302 PM EDT Sun Jul 19 2020

.SYNOPSIS...
Today will be very hot and humid with record challenging
temperatures. A few showers and thunderstorms are possible this
afternoon into tonight, mainly north and west of the Capital
District. A cold front will move across the region on Monday
with only isolated shower and thunderstorm potential. Dry and
slightly cooler weather is expected on Tuesday. The next chance
for showers and thunderstorms is on Wednesday.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
A Heat Advisory in in effect from 11 AM today to 8 PM EDT
Monday.

As of 248 PM EDT...Hot day continues. Dew points mainly in the
upper 60s with a few low 70s here and there. Valley heat indices
have risen to between 93 and 98 degrees. The main relief this
afternoon is the south to southwesterly breeze with occasional
gusts to 25 mph. A few isolated showers have developed over the
southwestern Adirondacks, Catskills and mid Hudson Valley.
However, main feature is long lived squall line now just
over western New York. Latest CAMs indicate this could reach
northern Herkimer and Hamilton Counties between 4 and 5 PM
bringing a chance for some severe weather there. Showers are
forecast to weaken as they approach the Capital District around
7 PM, but there is still some question on how much weakening
actually occurs.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY/...
The focus for this evening will be the advancement of showers
and thunderstorms and how intense they will be upon arrival.
Guidance continues to show a weakening trend as they move
eastward, mainly due to the loss of daytime heating and weak
upper-level forcing and shear over the area. Should storms
maintain themselves long enough, some gusty winds and heavy
rainfall will be possible to just west and north of Albany.
The Storm Prediction Center continues a Marginal Risk for
severe thunderstorms for this area with a Slight Risk clipping
far northwestern Herkimer County. Outside of this area, slight
chance to chance pops are maintained for showers. However,
850mb theta-e values remain very high overnight and PWATs rise
to 1.5 to 2 inches across the area so an isolated robust
thunderstorm with a heavy downpour is not out of the question.
With an increase in cloud cover and the continued southerly
flow, it will be a warm and muggy night with lows ranging from
the upper 60s in the higher terrain to the low to mid-70s in the
valleys.

Monday, a cold front will push eastward across the region
during the day. Latest guidance has the front clear Litchfield
County in the far southeast around 2 PM. Isolated
showers/thunderstorms are anticipated with the better chances
south and east of the Capital District (where the front will be
crossing during the late morning/early afternoon). High
temperatures will range from the upper 70s to lower 80s across
the higher terrain to the upper 80s and lower 90s in the valleys
(with the highest values in the mid-Hudson Valley). Heat Index
values between 95 and 103 are still possible from the Capital
Region and points south and east; therefore the Heat Advisory
will continue in these areas.

High pressure will then build eastward across the region with
dry weather Monday night through Tuesday. The air mass will be
a bit more comfortable than the previous days. Lows Monday night
will range from the upper 50s in the higher terrain to the low
to mid-60s. Highs Tuesday will range from the 70s in the higher
terrain to the 80s in the valleys.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
The long term period will look fairly summer-like with afternoon
highs each day in the 80s and a few chances for afternoon
thunderstorms.

To start the period, a low pressure system will track across the
Great Lakes and into New England. This will allow for a warm front
to lift north through the region Wednesday, bringing increased
humidity levels and chances for showers/storms. The low tracks
further east into western Maine Thursday-Thursday night, sending its
surface cold front through the region. This will lead to the threat
for showers and thunderstorms throughout the day Thursday with highs
reaching the upper 80s in the valleys (low 80s elsewhere). Depending
on the timing of the frontal passage, could see some of the storms
getting strong to potentially severe with ample surface based
instability and lift with the front.

High pressure builds in behind the front, bringing a reprieve to
humidity levels and above normal heat. Friday and Saturday look dry
with mostly sunny skies and highs in the upper 70s to mid 80s.

&&

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
The main forecast concern for the terminals is the potential for an
isolated shower/thundershower this afternoon into this evening ahead
of the potential for a heavier, more widespread rain/thunder threat
later this evening/tonight.

As of 1pm EDT, WSR-88D doppler radar depicted isolated
shower/thundershower development to our west-southwest across south-
central New York, southern New York (southwest of Ulster County)
into northeastern Pennsylvania. This development is ahead of a long
lasting MCS that has been tracking across the Upper Midwest/Great
Lakes region overnight and through this morning. Regarding the
isolated development this afternoon, have opted to keep the
terminals dry given its low coverage and weak nature.

With regards to the MCS to our west currently over Lake Erie
and Lake Ontario, we continue to keep close watch on its
evolution. Hi-res guidance is split on what happens with
regards to the MCS with the 3km NAM breaking the line up as it
tracks east closer to our FA and the latest HRRR run keeping the
line intact though in a weaker state as it approaches our FA
from the west. We do have an EML/cap around 615mb. Should this
line hold, it will arrive between 22z-23z this evening with the
potential for additional development after 04z. For now, have
included Prob30 -SHRA for KGFL between 06z-07z with the rest of
the terminals remaining dry with just increased cloud coverage.
Will make the necessary AMDs if need be. Any residual shower or
thunderstorm activity should come to an end between 06z- 07z.

Winds will be mainly out of the southwest 10-15 kts through this
afternoon/evening with gusts between 20-25 kts. Tonight, winds will
subside 5-10 kts.

Outlook...

Monday Night: No Operational Impact. NO SIG WX.
Tuesday: No Operational Impact. NO SIG WX.
Tuesday Night: No Operational Impact. NO SIG WX.
Wednesday: Moderate Operational Impact. Likely SHRA...TSRA.
Wednesday Night: Moderate Operational Impact. Chance of SHRA...TSRA.
Thursday: Moderate Operational Impact. Chance of SHRA...TSRA.
Thursday Night: No Operational Impact. NO SIG WX.
Friday: Low Operational Impact. NO SIG WX.

&&

.FIRE WEATHER...
Humidity will increase to between 80 and 95 percent tonight
along with the chance for showers and thunderstorms, mainly
north and west of the Capital District. Minimum RH values Monday
afternoon will be 40 to 50 percent. RH values are forecast to
recover Monday night back to 85 to 100 percent.

&&

.HYDROLOGY...
No problems are expected on the main stem rivers in the ALY
Hydro Service Area over the next week. Forecast rainfall during
this period ranges from 0.75 to 2 inches. Isolated to scattered
showers and thunderstorms are expected tonight into Monday,
mainly north and west of the Capital District with some locally
heavy downpours possible, but not over a wide enough area to
have big impact on main stem rivers. The next chance of
precipitation will be on Wednesday. Much of the area remains in
abnormally dry to moderate drought conditions per the latest US
Drought Monitor, with streamflows well below normal.

and forecast river stages and lake elevations, please visit the
Advanced Hydrologic Prediction Service /AHPS/ graphs on our
website.
