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 Buffalo, NY wrote its last area forecast discussion before this river flood warning went out at Apr 20, 10:47 PM EDT, 1 hour 4 minutes earlier.

Area forecast discussion, Apr 20, 10:47 PM EDT, 1 hour 4 minutes before

Area Forecast Discussion
National Weather Service Buffalo NY
1047 PM EDT Thu Apr 20 2017

.SYNOPSIS...
Showers and thunderstorms will taper off overnight with the
passage of a cold front. Behind this cold front, mainly dry
conditions will persist across the Eastern Great Lakes into the
beginning of next week.

&&

.NEAR TERM /THROUGH FRIDAY/...
A complex area of low pressure loosely centered across Southern
Ontario province will track eastward overnight. A warm front
associated with this is across the Western Southern Tier late
this evening, with its cold front still to our west across Ohio.
The severe weather threat is pretty much over, with radar
showing storms weakening across our area as the atmosphere
becomes more stable.

There still remains a risk for flooding overnight, though this
is mostly due to previous rainfall. Moderate to heavy rain will
continue to move eastward into an area which has not gotten as
much rain from the first round. There still will be some
thunderstorms embedded in this.

Otherwise, precipitation will taper to showers later tonight,
with patchy fog likely to develop along the rather ill-defined
cold front.

For Friday a few rain showers will start the day across the Eastern
Lake Ontario region. This activity will end through the day as
colder and drier air pushes eastward behind the cold front. Clouds
will likely remain tough across the region, though some breaks of
sunshine will be possible. The clouds and cooler air aloft will only
yield highs in the 50s tomorrow, though some early morning lower
60s are possible across the northern Finger Lakes.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/...
Low pressure over Quebec will lift northeast with limited low level
moisture lingering across the north country. High pressure centered
over the Upper Mississippi Valley Friday night will begin to
build across western New York.

While a mid level trough within the northern branch of the split
flow will sweep across our forecast area on Saturday...surface high
pressure and relatively dry air in the mid and upper levels will
continue to promote dry uneventful weather. Model guidance continues
to hold precipitation associated with a low over the Southeast/mid-
Atlantic to our south across central Pennsylvania on Saturday and
Saturday night.

Temperature-wise look for a cool start to the period. Lows Friday
night within a few degrees of 40 with the interior southern tier and
north country seeing lows into the mid 30s. Cloud cover should
preclude any frost issues. Highs on Saturday will struggle to reach
the 50 degree mark.

High pressure will still dominate on Sunday/Sunday night with some
milder air beginning to overspread the region. Highs Sunday return
to more normal readings around the 60 degree mark. Temperatures
Sunday night fall back into the 30s. With clearing skies...patchy
frost could be possible across the interior sections of the western
southern tier.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
Medium range models continuing to advertise a progressive zonal flow
pattern during this period. Surface ridging will continue the dry
but cool weather pattern as we start out Monday and Monday night.
After highs only in the 50s Monday, another cool night is expected
for the interior southern tier and north country Monday night with
lows in the 30s and possible frost issues.

The progressive pattern will send an initial wave over top the
southern ridge by Tuesday which looks to minor out and should
have little impact on our weather. A more vigorous system looks
to develop later in the period which will bring chances for
showers and possible storms back into the forecast for Wednesday
and Thursday. Substantial temperature moderation will bring
temperatures well above normal during the mid week period.

&&

.AVIATION /02Z FRIDAY THROUGH TUESDAY/...
At 02Z...heavier showers and thunderstorms have exited east of
Rochester, with diminishing chances for convection at
BUF/IAG/ROC/JHW for the remainder of the night. However, there
still will be plenty of low moisture, with this likely to
remain trapped overnight.

Conditions will vary, but there generally should be a lowering
of CIGs, especially along a cold front which is forecast to move
across the area late tonight. This will also result in patchy
fog, with fairly widespread IFR conditions expected to develop
late tonight.

Conditions will improve gradually on Friday as slightly drier
air builds in. Expect mainly MVFR conditions with some VFR
conditions during the afternoon.

Outlook...

Friday night...mainly VFR, some patchy fog/IFR across the So. Tier.
Saturday...VFR.
Sunday through Tuesday...Mainly VFR.

&&

.MARINE...
Easterly winds will maintain waves 3 to 5 feet on the western half
of Lake Ontario, with small craft advisories through the early
morning hours. These winds will diminish overnight, with
improving conditions.

On Friday westerly winds will then flow across the eastern Great
Lakes. This will bring winds to 15 to 20 knots, with waves building
towards SCA levels.

&&

.HYDROLOGY...
This system will bring a total of 1-2 inches to most locations.
Radar estimates and observations show the highest rainfall
amounts are across southern portions of Erie and Genesee
counties where an Areal Flood Warning is in place. This area
averaged around 2 inches. There have been several reports of
road closures in this area, due to both ponding of water and
rises on creeks and streams. These should crest rather quickly,
with improving conditions expected late tonight.

This also will result in rises on several forecast point. Of
greatest concern is the Buffalo Creeks basin, where several
forecast points are likely to reach action stage. Cazenovia,
Cayuga, and Ellicott Creeks all bear close attention with crests
expected to be near flood stage. There will also be rises on the
slower responding Rochester Creeks, with Oatka creek also likely
to crest pretty close to warning stage.
