Area Forecast Discussion
National Weather Service Albany NY
805 PM EDT Sat Jul 1 2017

.SYNOPSIS...
A frontal boundary will move across the region tonight
with still warm but a bit less humid conditions on Sunday. An
isolated thunderstorm will be possible on Sunday mainly west and
north of Albany. Another cold front passes on Monday, bringing a
chance of showers and thunderstorms to southern portions of the
forecast area. Dry and seasonable weather remains in the forecast
for Independence Day.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
Severe thunderstorm watch canceled.

Convection continues to slowly diminish with the loss of early
July sunshine as instability is waning. Seems the flood threat
was more an issue today as mid level lapse rates were less than
ideal but warm cloud depth was quite deep which resulted in
more efficient precipitation producers. As PWATs were quite high
in excess of 1.75", which is 2-3 standard deviations above
normal, along with low level jet magnitudes of 30-40kts along
with antecedent wet conditions were enough for more flood
reports than severe reports. So with this update, canceled the
Severe Thunderstorm Watch, reduced PoPs/Wx per trends and
tweaked hourly values per observations and trends.

Prev Disc...
Scattered to broken line of convection continues to
impact and cross over the region through the balance of the
afternoon and evening hours. Mesoscale window and our special
balloon sounding suggests mid-level lapse rates were less than
ideal for deeper/vigorous updrafts. However, a few convective
cells able to act upon stronger insolation and along the
differential heating boundary near I 90 and north of the Capital
Region are where some wind reports were received. The other
hazard has been flooding as warm cloud depth has been quite high
and efficient precipitation processes. As seen in the H2O vapor
loop, synoptic flow aloft remains southwest and was nearly
parallel to the surface features. So training echoes along with
PWATs close to 2 inches has resulted in heavy rainfall. Toward
late this afternoon and evening, the upstream trough axis
approaches which will act to enhance and wind magnitudes and
slowly back the flow to allow for further forward momentum and
reduce time of falling rainfall over one location. So after
close coordination, no flash flood watch at this time. The loss
of daytime heating should also reduce convective trends along
both the pre-frontal trough and cold front upstream (approaching
Buffalo area at this time). So we will reduce PoPs/Wx through
the evening hours. Overnight, could be some patchy fog where
winds are able to decouple and moist ground. Lows will remain
rather mild for the beginning of July with mainly 60s expected.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/...
A drier airmass will be in place on Sunday, though dewpoints are
still forecast to be in the low to mid-60s for the valleys. High
temps will still be on the warm side with H850 temps still in
the mid-teens, so upper 70s to upper 80s for much of the
forecast area. Midlevel flow still remains broadly cyclonic, so
an afternoon shower or storm cannot be ruled out, mainly over
the higher terrain and mainly to the north and west of Albany.
Hires NAM3km suggests a narrow line of convection along the
leading edge of the height fall along with lake breeze
convergence may be enough for the chance of convection.

Sunday night, another shortwave trough is forecast to approach
the area from the northern Great Lakes. Some upstream activity
tied to the diurnal cycle along the attendant cold front may
work its way into the Southern Adirondacks before diminishing
Sunday evening. So we will taper back PoPs/Wx through the early
evening hours and a mainly dry for the overnight period. Under a
partly cloudy to mostly clear sky, and lower dewpoints into the
50s, overnight lows should drop back to 60-65F for valley
locations and 50s elsewhere.

&&

.LONG TERM /MONDAY THROUGH SATURDAY/...
The start of the work week begins with a boundary stalled in our far
southeastern CWA and a trough swinging through NY and western New
England. The upper levels winds within this trough are rather strong
with the base of the trough featuring 40 - 50 knots at 500mb. The
base actually looks to set up through the central portion of our
region which could act as the best chance for showers to develop
during the afternoon. Depending on just where the front stalls will
determine if any thunderstorms could develop in our CWA. Current
guidance continues to suggest that portions of Ulster/Dutchess and
Litchfield counties could have some instability (less than 500 J/kg)
so have included chance thunder in those areas. Temperatures will be
seasonable in the upper 70s/lows 80s with dew points still a bit
high in the low 60s due to continued westerly flow.

Good news for those interested in being outdoors for the Fourth of
July holiday. Winds shift northwest Monday night as a secondary cold
front ushers in Canadian high pressure for Tuesday. Expect mostly
sunny skies and comfortable temperatures in the 70s/near 80 with
lower dew points in the 50s. Great weather for fireworks and
enjoying the outdoors in eastern NY and western New England.

The region should remain dry Wednesday as the 1020-1025mb high
shifts east into New England. Winds become southerly and should lead
to WAA and increasing cloud coverage through the day ahead of the
next disturbance. A shortwave in the Midwest looks to move into the
mid - Atlantic (potentially riding along the front from Monday
night) and by Thursday bring us the next threat for rain. Current
guidance still shows discrepancies on rain arrival time with the EC
the earliest and the Canadian the latest. Have gone with the GFS/EC
blend and gave high chance POPs for the Wed night, Thursday and
Thursday night periods. For now, split chance and slight chance POPs
for Friday as the system exits. Given the strength of the WAA
and PWATs potentially increasing to well over 1 inch, rain could
be widespread throughout the CWA with periods of
steady/moderate rain possible.

A potentially impressive longwave trough from Canada dips into the
Northeast heading into next weekend keeping us unsettled with
multiple threats for precipitation. Most should be diurnally driven
so put slight chance POPs for now. Low confidence on which exactly
locations will see precipitation given this is the Day 6 - 8 period
so put the threat in all zones for now.

&&

.AVIATION /00Z SUNDAY THROUGH THURSDAY/...
Still a few showers possible this evening at the TAF sites, but
the strongest storms have moved east or dissipated. Expect
gradual clearing skies tonight with fog formation expected at
all the TAF sites. IFR fog and some lower ceilings expected at
KGFL and KPSF. At KALB, MVFR expected with IFR possible. Mainly
MVFR conditions expected at KPOU. Fog and low ceilings should
lift tomorrow morning by 13Z all TAF sites. VFR conditions
expected.

Winds tonight will generally be light and westerly. Westerly
winds at 10 to 15kts forecast on Sunday.

Outlook...

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

&&

.FIRE WEATHER...
A warm and very moist airmass is in place with showers and
thunderstorms expected through this evening. Sunday will
feature slightly drier conditions with RH values falling into
the 40s and 50s, along with westerly winds of 5 to 10 mph
gusting to 20 mph at times. A cold front works through Monday,
with a chance of showers and thunderstorms mainly south of the
Capital District. Drier air will filter in in the wake of the
front, but temperatures will still be on the warm side for
southern portions of the forecast area.

&&

.HYDROLOGY...
Training storms have resulted in some flooding in the Glens
Falls area (over 2 inches of rain thus far) and western Mohawk
Valley. A warm and very moist airmass is in place through this
evening so some more pockets of heavy rainfall are
expected. Basin averages of 1 - 2 inches or greater are
possible in thunderstorms. River rises along the western Mohawk
and upper Hudson are being observed with minor flooding at Kast
Bridge.

A drier trend takes shape for Sunday and Monday, though a few
showers and storms cannot be ruled out either day. These storms
will carry less of a heavy rain threat, however.

and forecast river stages and lake elevations, please visit the

.CLIMATE...
Glens Falls Airport has seen over 3 inches of rain thus far.

transmit a record report.
