AREA FORECAST DISCUSSION
National Weather Service Albany NY
237 PM EDT Thu Jul 2 2020

.SYNOPSIS...
A weak cold front will move across the area tonight and tomorrow
with isolated to scattered thundertorms into this evening, then
another round of scattered showers and thunderstorms on Friday.
Mainly dry and warm weather can then be expected for the holiday
weekend.

&&

.NEAR TERM /THROUGH TONIGHT/...
Scattered thunderstorms are developing over the Adirondacks this
afternoon south of a weak backdoor cold front that is dropping
south toward the area from Quebec. The atmosphere is moderately
unstable this afternoon into this evening with MLCAPE values
ranging mostly from 1000 to 2000 J/kg. One or two storms could
become strong or even marginally severe as deep layer shear
values around 30 kts will be enough for some storms to organize
into small convective clusters. In addition, steep low- level
lapse rates with DCAPE values from 1000 to 1200 J/kg could
result in some sneaky wet microbursts with localized damaging
wind gusts possible. The best chance for storms will be over
higher terrain where differential heating can result in some
small-scale enhanced lift. Otherwise, little-to-no large-scale
forcing today should keep storm coverage low with pops of 20 to
40 percent adequate for our area into this evening.  Scattered
storms will end across the area by mid- evening with mainly
clear skies developing overnight although some clouds may
increase from the north later tonight with the approach of the
cold front.

&&

.SHORT TERM /FRIDAY THROUGH SUNDAY/...
Weak frontal boundary will slide across the area on Friday
while a mid-level short wave digs southeast from Quebec in
northwest flow aloft. This forcing should result in another
round of showers and thunderstorms firing during the afternoon.
This will be a rather weak and subtle frontal boundary, and
determining the exact location of storms Friday afternoon at
this point is not easy, although the latest round of operational
modelling seems to be targetting the southern half of our area.
Forcing aloft should be sufficient for high chc pops for the
entire area Friday afternoon, while the highest pops will be
over terrain in the south closer the surface front including the
Catskills and Litchfield Hills. Conditions will once again be
rather warm and muggy with high temperatures in the 80s and dew
points in the mid to upper 60s.

Saturday through Sunday appears to be mainly dry and quite warm
as our area will be near the northeast edge of a large upper
level ridge covering the central CONUS. The best chance for a
thunderstorm during this period will be Sunday afternoon as a
short wave rotates southeast around the northeast rim of the
ridge. Otherwise temperatures will be a bit above normal through
this period with highs mainly 85 to 90 and lows mostly in the
60s.

&&

.LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/...
During the extended period, our region will be situated along the
northern periphery of strong upper level ridging that extends across
much of the central and eastern CONUS.

While there may be a slight to low chance each day of a diurnally-
driven shower or thunderstorm, coverage of storms is expected to be
rather low due to limited forcing.  The best chance may be towards
later in the week (Wednesday, Thursday or Friday), as some upper
level disturbances rotating through the zonal flow aloft will move
across the area and provide more lift and coverage of storms.  The
timing of these subtle feature is still rather uncertain, so which
day will be most active is still unknown at this time. Showers and
storms should diminish after the evening hours, so most overnight
hours look to be dry through the week.

Temperatures are expected to be above normal through the week.  850
hpa temps will rise from around 15 to 17 C on Monday to 18 to 20 C
for the rest of the week.  This should allow temps to reach into the
upper 80s to low 90s for highs in valley areas.  Overnight lows will
remain muggy in the 60s to low 70s.  With dewpoints in the 60s
through the week, it will feel rather muggy and sticky each day.
Will need to watch for heat index values getting close to the mid
90s by the middle to latter portion of the week and heat advisory
statements could be needed at some point.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
VFR conditions ongoing this afternoon with a backdoor cold front
pushing southward towards to the Canadian/NY border. As a
result, scattered showers and thunderstorms are possible this
afternoon which is why we have included VCSH starting around
20UTC at GFL, ALB and PSF. Given how far north the front is
located, we chose not to include the chances for showers at POU.
In addition, since thunderstorms activity should be isolated to
scattered, we did not include VCTS at this time. However, we
will amend the latest TAFs based on radar trends and coverage.

As the backdoor cold front sinks southward into New York State
tonight, chances for isolated showers linger so continued the
VCSH mention through most of the night. Once the front reaches
the TAF terminals from north to south by 09 - 11 UTC, ceilings
will likely become MVFR at GFL, PSF and ALB. The lowest ceilings
are expected at PSF and GFL and we showed the potential for
near IFR ceilings with a mention of SCT010. We did not have
enough confidence for MVFR ceilings at POU so we only show
SCT025.

MVFR ceilings should improve to VFR by late morning tomorrow but
showers and thunderstorms will once again have the potential to
develop towards the end of the TAF period. Current confidence
for the showers and storms to be tied to the terrain initially
which is why we only showed a PROB30 for -TSRA at PSF.

Winds will be north-northwest today near or less than 5kts through
today (higher in any thunderstorms) before becoming near calm
tonight. Winds should become north-northeast late tonight into
early tomorrow morning once the backdoor cold front pushes
through the region and be sustained near or less than 5kts.

Outlook...

Friday Night: Moderate Operational Impact. Scattered SHRA...TSRA.
Independence Day: Low Operational Impact. NO SIG WX.
Saturday Night: No Operational Impact. NO SIG WX.
Sunday: Low Operational Impact. Slight Chance of SHRA...TSRA.
Sunday Night: No Operational Impact. NO SIG WX.
Monday: Low Operational Impact. Slight Chance of SHRA...TSRA.
Monday Night: No Operational Impact. NO SIG WX.
Tuesday: Moderate Operational Impact. Chance of SHRA...TSRA.

&&

.FIRE WEATHER...
A cold front in Canada will drop south today through Friday.
Above normal temperatures and isolated thunderstorms are
expected today. Temperatures near normal Friday with scattered
thunderstorms as the cold front tracks through our region.
Mainly dry weather and slightly above normal temperatures are
expected for the holiday weekend.

The RH values will be 40 to 55 percent this afternoon, and then
increase to 80 to 100 percent Friday morning. RH values will
drop to 55 to 70 percent Friday afternoon with scattered
thunderstorms.

The winds will be north to northwest at 15 mph today before
become light tonight. Winds become northeast to east Friday at
15 mph or less.

&&

.HYDROLOGY...
Widespread hydrological issues are not expected on the main
stem rivers the next several days for the ALY Hydrological
Service Area.

Much of the HSA remains in either Abnormally Dry or Moderate
Drought category per the latest US Drought Monitor issued last
Thursday. Most rivers remain below the 25th percentile of 7-day
average streamflow.

Very warm and mainly dry weather is expected today, isolated
showers and thunderstorms cannot be ruled out especially over
the higher terrain. Additional rainfall is expected on late
Thursday night into Friday with a back door cold front.

Some locally heavy rainfall is possible from any thunderstorms
on Friday. Basin average rainfall my range from a few tenths to
up to an inch. Drier weather is expected on the holiday weekend.

observed and forecast river stages and lake elevations, please
