What forecasters said that day

The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Albany, NY wrote its last area forecast discussion before this river flood warning went out at Oct 31, 7:54 PM EDT, 1 hour 1 minute earlier.

Area forecast discussion, Oct 31, 7:54 PM EDT, 1 hour 1 minute before
AREA FORECAST DISCUSSION
National Weather Service Albany NY
754 PM EDT Thu Oct 31 2019

.SYNOPSIS...
Periods of light rain will transition towards periods of
moderate to heavy rainfall through tonight across the region as
a potent storm approaches. Occasional gusty winds will accompany
this storm system. As strong cold front will cross and exit the
region Friday with windy conditions expected. Cooler and mainly
tranquil weather for most of the region this weekend, however,
some lake effect activity may impact portions of the western
Adirondacks.

&&

.NEAR TERM /UNTIL 3 AM FRIDAY MORNING/...
     Wind advisory in effect...
     Flood watch issued for areas along the Interstate 90
corridor to southern VT and points northward...
     Severe Thunderstorm Watch until 2 AM...

As of 630 PM EDT...Convective line has increase in coverage and
intensity, without lightning at this time, across the I 81
corridor. While downstream activity remains rather light with
showers and periods of drizzle, low level jet magnitudes are
increasing per the VWP with magnitudes over 60kts just above
50kts. Expectations are for the line upstream to increase with
intensity as low level convergence and upper diffluence from
approaching negatively tilted trough to enhance wind dynamics
with this line the next few hours. Dewpoints at most locations
are well into the 60s and temps generally between 65-72F. So
surface based instability is rather low but kinematics are quite
high.

Prev Disc...
Not much changes from previous forecast discussions. Potent
upper wave across the western Great Lakes and mid-Mississippi
was evolving toward a negative tilted nature as 140kt+ jet was
advancing northward into the heart of the Great Lakes. Deep
moisture transport and high anomalous PWATs and moisture flux
was advancing northward along the eastern seaboard. Bands of
rainfall was just west of our CWA, however, low level jet streak
and theta-e advection will quickly overspread the region early
this evening and continue into the early overnight period.

As this upstream storm deepens and becomes negative tilted and
near vertically stacked, strengthening cold frontal zone will
ignite a line of broken convection. Shear parameters are quite
high along with those higher moisture profiles where SPC has
upgraded our region into a slight risk category for severe
thunderstorms overnight. Per the hi-res reflectivity guidance,
seems the line of convection will approach our western zone
close to 04Z, then quickly sweep across the region and east by
no later than 09z. Rainfall rates up to or over 1 inch within an
hour is possible, especially into the higher terrain of the
Dacks and southern Greens.

&&

.SHORT TERM /3 AM FRIDAY MORNING THROUGH SATURDAY/...
High Wind Warning from 5 AM to 6 PM Friday...
     Flood Watch remains until Friday Evening...

Potent storm wraps up to the north of St Lawrence Valley.
Combination of large isallobaric rises and deep mixing layer
heights and tight pressure gradient will result in high momentum
transfer of wind magnitudes. 925MB/850MB anomalies of 3-4
standard deviations above normal from the west per the SREF/GEFS
also support an upgrade to the warning area. Elsewhere, we will
continue with the wind advisory at this time. Under strong cold
advection, temperatures likely will not climb too much from the
overnight lows in the morning. There will be increasing amounts
of sunshine, especially south of Albany through the day as
downsloping from the mountains will aid with drying things out.

Friday evening into Saturday, high pressure with relaxing
gradient and clearing skies will result in tranquil weather.
Issue will be the chilly temperatures Friday night as most of
the region will be at or freezing. Highs Saturday back mainly
into the 40s with around 50F for the valley locations.

&&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
The main story for the long term period will be a period of below
normal temperatures arriving during the second half of next week and
given we have a few chances for precipitation, it is possible that
some areas of eastern NY and western New england may see the first
snow flakes of the season. Read on for details.

We begin the long term Saturday night with a potent trough axis
moving through the Northeast with good consensus among the latest
model guidance that it will become negatively tilted. While
moisture along the associated surface cold front is rather
lackluster as per the latest 700mb RH guidance, there is a good shot
of cold air arriving in the wake of the frontal passage towards 12z
Sunday. With 850mb isotherms between -6C and -8C moving over the
warm Lake Ontario waters, the critical 13C threshold for lake effect
showers should be surpassed. The guidance continues to show strong
enough westerly flow that lake effect showers should extend into the
southern Adirondacks. Temperatures Saturday night are expected to
fall into the upper 20s by 12z Sunday in the Adirondacks which means
that while initial showers may be rain or rain/snow mix but should
become lake effect snow showers. Snow accumulations are possible in
the higher terrain of the southern Adirondacks. Elsewhere in eastern
NY and western New England should remain mainly dry but temperatures
will turn chilly with A.M lows expected to reach into the low to mid
30s. Winds should also turn breezy which should make it feel even
cooler.

Cold air advection continues into Sunday with breezy conditions
still in place as high pressure from the mid-Atlantic noses
northeastward into the Northeast. Boundary layer mixing under the
cold air advection regime should deepen which should prevent
temperatures from rising too much during the day. ECMWF and GFS MOS
probabilistic guidance for many of our sites still show the 10P and
50P percentiles for high temperatures on Sunday below 50F. Thus, we
show highs on Sunday only reaching into the mid - upper 40s for most
areas with the eastern Catskills, southern Adirondacks and southern
Greens remaining below 40F. Lake effect snow showers in the Dacks
from the overnight should mix with and turn to mainly rain by the
afternoon.

As high pressure takes control Sunday night, winds should decrease
and the increased subsidence should shut off the lake effect
showers. Skies should clear overnight and provide a good radiational
cooling set-up. In fact, lows should drop below freezing throughout
eastern NY and western New England for the first time this season.
This could be the first freeze for Albany which would be the latest
first freeze since 1931.

After a cool start to our Monday, high pressure in place should give
us a dry day with seasonable temperatures reaching into the upper
40s to low 50s. As our high shifts into New England on Tuesday,
southwesterly flow should usher in milder temperatures with our next
potent cold front and upper level shortwave moving through the Great
Lakes. The latest GEFS show 850mb isotherm anomalies upstream behind
the front ranging 2-3 standard deviations below normal. Thus,
confidence is increasing that the Northeast could experience yet
another period of below normal temperatures heading into the end of
the work week. The initial cold front looks to move through our
region Tuesday night with the chillier air mass arriving with a
secondary boundary arriving either Thursday night or Friday.

Guidance shows an active 500mb pattern for the second half of the
week with multiple shortwaves rotating around the base of the main
longwave trough positioned over southern Canada. With cold air
advection ushering in 850mb isotherms down to potentially 1-2
standard deviations below normal per the GEFS, it's possible that
some areas even outside of the higher terrain could see their first
flakes of the season towards the end of the work week. Still too
early for specifics but the upcoming pattern is favoring a more
winter feel.

&&

.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
A cold front will move across the region tonight accompanied by
moderate to heavy rainfall with MVFR-IFR conditions. There is a
very strong southerly low level jet ahead of the front. The
00Z/ALY sounding measured 50 knots of wind at 1500 feet. Hence
have low level wind shear in TAFs and have strong wind gusty
associated with the line of showers as they move through this
evening into the overnight just head of the boundary. Also the
gradient wind flow strong and gusty. Winds will shift to the
west with the passage of the cold front and rain will linger for
a few hours. Conditions are expected to improve to VFR after
sunrise with cloud cover eventually decreasing by late in the
day Friday as the storm moves away and some ridging builds in.

Strong and gusty south-southwest winds 15 to 25 mph ahead of
the front gusting up to 30 to 35 knots. Winds will increase
after sunrise in strong cold air advection with sustained winds
20 to 30 knots with gusts up to 45 knots. Winds will begin to
weaken by early evening.

Outlook...

Friday Night: No Operational Impact. NO SIG WX.
Saturday: No Operational Impact. NO SIG WX.
Saturday Night: No Operational Impact. NO SIG WX.
Sunday: No Operational Impact. NO SIG WX.
Sunday Night: No Operational Impact. NO SIG WX.
Monday: No Operational Impact. NO SIG WX.
Monday Night: No Operational Impact. NO SIG WX.
Tuesday: Moderate Operational Impact. Chance of SHRA.

&&

.FIRE WEATHER...
Periods of rain, heavy at times, will impact the region through
tonight. This will result with minimal to no fire weather
related impacts during this time period. Drier weather returns
later Friday and into most of the upcoming weekend, with the
exception of the Adirondack region where some lake effect
activity with showers and clouds may linger.

&&

.HYDROLOGY...
Flood Watch extended into Friday evening...

Latest rainfall forecast totals and river forecast guidance from
the River Forecast Center point toward 1 to 3 inches of rain for
portions of the Adirondacks and southern Greens with 1 to 2
inches elsewhere. Given our recent wet pattern and elevated
river levels, points along the Mohawk, upper Hudson, Adirondack
head waters, Walloomsac and Hoosic may approach or exceed minor
or moderate flood stage. Furthermore, where poor drainage due
to blocked storm drains from fallen leaves may lead toward minor
flooding as well. The bulk of the heaviest QPF is expected to
fall tonight where rainfall rates up to one inch within an hour
is possible.

Drier weather returns Friday and into most of the area into the
weekend.

observed and forecast river stages and lake elevations, please

.CLIMATE...
If the temperature falls to 32 degrees or less at Albany
International Airport Saturday morning, it will be the latest
first freeze of the season since 1931, when the first freeze was
November 6. The latest first freeze is November 12, 1883.
