...FLOOD WATCH IN EFFECT FROM THURSDAY MORNING THROUGH FRIDAY
MORNING...

The National Weather Service in Buffalo has issued a

* Flood Watch for a portion of western New York...including the 
  following county...Northern Erie. 

* From Thursday morning through Friday morning.

* Ice jams will again become a concern as river ice starts to 
  break up with warmer temperatures arriving Thursday and Thursday
  night along with runoff from melting ice and rainfall.

* The most susceptible areas for potential ice jams are the
  Buffalo area creeks, including the Cazenovia Creek, Ellicott 
  Creek, Buffalo Creek, and Cayuga Creek.

* Much colder temperatures arrive during the day Friday, which
  should again freeze river ice into place and halt runoff.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flood Watch means there is a potential for flooding based on
current forecasts. You should monitor later forecasts and be
alert for possible flood warnings. Those living in areas prone to
flooding should be prepared to take action should flooding
develop. Stay tuned to weather radio or other radio and tv
stations for further details or updates.

What forecasters said that day

The local office's own words before this flood watch 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 flood watch went out at Feb 6, 8:29 AM EST, 3 hours 54 minutes earlier.

Area forecast discussion, Feb 6, 8:29 AM EST, 3 hours 54 minutes before
Area Forecast Discussion
National Weather Service Buffalo NY
829 AM EST Wed Feb 6 2019

.SYNOPSIS...
An area of low pressure will bring a period of freezing rain to the
region today and tonight, with a change to plain rain across much of
Western New York this afternoon and evening as milder air bulges
northward. On Thursday another surface low will track to our west
and north, bringing milder and wet conditions during the day
followed by windy and colder conditions Thursday night and Friday.
Cold air flowing across Lake Ontario Friday night and Saturday will
bring accumulating lake effect snow to areas east and southeast of
the Lake.

&&

.NEAR TERM /THROUGH TONIGHT/...
Amorphous inverted surface troughing can be noted extending up
into western New York in the surface observations this morning.
The axis of this aligns fairly well with the surface freezing
line which currently extends through central Chautauqua County,
through far southern Erie County, Wyoming County, and into
Livingston County. As we go through the day, hi-res model
solutions favor closing off the troughing into a closed surface
low and tracking said low down the then location of the surface
trough axis. The exact corridor of this track isn't particularly
well agreed upon even at this close juncture, however the mere
presence of the closed surface circulation suggest a stronger
possibility of sub-freezing temperatures lingering to the north
of its track through the day than an open solution would. That
said, northeasterly flow to the north of the track will
continually feed colder air toward the western Lake Ontario
shoreline through the day. This will lead to the strongest ice
accumulations north of the Niagara Escarpment, where a third of
an inch still seems likely. These numbers will taper off to the
south toward Buffalo and Rochester, both of which have several
hours of freezing rain likely. However, in both of these places,
freezing rain should eventually yield to plain rain because of
how close the surface low will track to them.

Farther south, across the Souther Tier, many places will begin
as plain old rain this morning. Wet bulb effects being nearly
nil, and surface dewpoint depressions likewise being nearly nil,
won't allow for temperatures to remain suppressed below freezing
with modest warm advection ongoing. That said, a few of the
lower spots in Chautauqua, Cattaraugus, and Allegany counties
may experience brief icing, so the winter weather advisories
will be kept for a few hours.

Behind the passing surface wave later today, large scale forcing
for ascent should start to wane. This will allow for steady
precipitation to end around the evening rush hour in Buffalo
and shortly thereafter in Rochester, while lingering in the
North Country through the evening. However, almost no advection
is present in the wake of this wave today. As a result, abundant
low level moisture will likely result in widespread
drizzle/freezing drizzle (dependent upon the surface
temperatures) and fog right into Thursday morning.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
A developing low pressure center will rapidly deepen through the
course of the day Thursday as it tracks to the west of New York
State. In the warm sector, temperatures will have the potential
to spike into the lower to mid 50s in areas south of the
Thruway as 850 mb temperatures surge toward +10C.

A soaking rain will arrive by afternoon, if not a bit sooner,
then spread quickly east across the remainder of the area
through Thursday night. There will be enough forcing into the
area to support a period of possible thunderstorms Thursday
night, and perhaps heavy rain. The rainfall associated with
this system will need to be monitored very closely as this
could be a significant rainfall event with amounts potentially
nearing an inch. Rainfall amounts of this magnitude could
certainly bring renewed hydrologic concerns, especially
considering the several ice jams which are currently in place
on some of the Buffalo area creeks.

The system dry slot will punch through the region late Thursday
night into Friday, as the low pressure center continues to
deepen as it lifts through Ontario into Quebec, forcing a
powerful cold front through the area. This will bring a quick
end to the precipitation as the cold front swings through. Cold
air will rapidly rush into the area in wake of the front, with
temperatures dropping into the 20s through the day Friday. There
will be the potential for a flash freeze given wet surfaces
from all the preceding rain.

In addition, an increasing pressure gradient coupled with drier air
and cold air advection into the region will likely result in a
period of strong gusty winds. The potential for the strongest
wind gusts look to be in the typically favored west-southwest
flow areas northeast of Lake Erie and Ontario, including the
Buffalo/Niagara Falls area over to Rochester. Momentum transfer
profiles suggesting these areas will likely see gusts of 50 to
55 mph, perhaps even higher. Wind headlines will need to be
considered as the event nears.

The incoming colder air will allow for a brief lake response later
Friday into Friday night, this will especially be the case east
and southeast of a fully open Lake Ontario. A few inches of
snowfall is not out of the question.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
On Saturday a cold...but increasingly dry west-northwesterly flow
will be in place across our region...in between departing low
pressure over Labrador and high pressure building across the Central
Great Lakes. This should result in scattered lake effect snow
showers gradually diminishing downwind of Lake Ontario...with mainly
dry conditions the rule elsewhere. With 850 mb temps in the lower
half of the negative teens...highs will struggle to get out of the
lower to mid 20s in most locations...with portions of the North
Country not making it out of the upper teens.

Saturday night and Sunday the aforementioned surface ridge will
settle southeastward and off the mid-Atlantic coastline...with
its axis drifting across our region and eventually into central
and eastern New York. This will provide our area with mainly dry
and quiet weather...with just an outside chance of some light snow
attendant to a developing weak baroclinic zone aloft/passing upper
level jet streak possibly reaching the Southern Tier later Sunday
afternoon. Otherwise temperatures will continue to run a bit below
average...with lows in the 5 to 15 above range Saturday night
followed by highs in the mid 20s to lower 30s on Sunday.

Sunday night and Monday the above mentioned weak baroclinic zone and
passing upper level jet will bring a general chance of some light
snow areawide...with the bulk of this likely to come Sunday night.
Following the passage of these features...Canadian high pressure
will then build across our region and bring a return to mainly dry
weather during Monday. As for temperatures...lows Sunday night
should range from the teens across the North Country/interior
portions of the Southern Tier to the lower 20s south of Lake
Ontario...with highs on Monday then climbing back into the upper
20s to mid 30s.

As we move on into the last 24 hours of this period...another system
of southern stream origins then looks to advance into the region
during the Monday night-Tuesday time frame. Given the distant time
frame and with model guidance not surprisingly all over the place on
its  strength...track...and timing...for now have just introduced
some broadbrush chance PoPs for rain and snow...with temperatures
nudging back up to a little above normal.

&&

.AVIATION /13Z WEDNESDAY THROUGH SUNDAY/...
For the 12Z TAFS a northeast wind will maintain a wealth of low
level moisture south of Lake Ontario, with IFR to lower
elevation MVFR ceilings.

An area of mixed precipitation is advancing up Lake Erie this
early morning and will reach the TAF sites by 13Z. A prolonged
period of freezing rain is likely as surface high pressure over
Quebec, and an inverted surface trough extending northeastward
from the Ohio Valley set the stage. The surface high will
provide low level cold air on a northeast wind, while aloft the
surface trough will bring milder and moist air
northward...producing a stout low level inversion. As the warm
air from south expands, it will likely change the freezing rain
over to plain rain for much of Western New York outside of the
southern Lake Ontario shoreline.

Ceilings will remain poor, with IFR ceilings likely expanding across
KBUF, KIAG and KROC within copious low level moisture. Visibilities
will largely fall within the MVFR range within the falling freezing
rain/plain rain...though heavier bouts of precipitation could yield
IFR visibilities.

Tonight the inverted surface trough will push eastward, with
convergence and lift sliding eastward. This will end the bulk of
precipitation through the night, though a chance of freezing
drizzle, plain drizzle will remain through 12Z with a wealth of low
level moisture lingering.

Outlook...

Thursday...IFR/MVFR with rain and possibly a thunderstorm.
Friday...IFR/MVFR windy with rain to snow. Saturday..VFR/MVFR with a
chance of snow showers. Sunday...VFR.

&&

.MARINE...
An inverted trough will pass across the Eastern Great Lakes region
today and tonight, with an easterly flow across Lake Ontario.
Freshening winds will increase to around 20 knots on the western
waters of Lake Ontario, with small craft advisories continuing. As
this surface feature advances eastward winds will slacken, with
conditions falling below small craft thresholds early Thursday
morning.

Another surface low will pass by to our west and north Thursday
night and Friday. This track, and deepening to the surface low will
bring much stronger winds...possibly to gale force on the Great
Lakes. This potential will be added to the HWO product.

&&

.HYDROLOGY...
Temperatures have been below freezing for several hours and
this has greatly slowed and will continue to diminish the
runoff, and eventually allow ice jams to lock in place. Because
of this, the Flood Watch is no longer in effect as NO NEW
flooding is expected through tonight. Some lingering flooding
remains, therefore please refer to any existing flood warnings
for more specific information.

Another system is expected to track to our west on Thursday,
with another period of warmer temperatures and rain expected.
This system has the potential to produce more substantial
rainfall from Thursday afternoon into Thursday night. This has
the potential to cause additional flooding in some areas due to
rainfall and run-off, depending on how much rainfall and how
warm it gets.

IMPORTANT NOTE: Users should be wary of unrepresentative gauge
readings with ice as hydro gauges are designed to measure for
ice free conditions. High levels seen on many of the Buffalo
Area Creek gauges are not representative of the true flow of
water. Ice buildup around the gauge can result in much higher
readings than are actually occuring on the river as a whole. For
these reasons, gauge readings due to ice jams are not counted
as records.
