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 Apr 13, 10:44 AM EDT, 4 hours 20 minutes earlier.
Area forecast discussion, Apr 13, 10:44 AM EDT, 4 hours 20 minutes before
Area Forecast Discussion
National Weather Service Buffalo NY
1044 AM EDT Fri Apr 13 2018
.SYNOPSIS...
A warm front will lift north into the Southern Tier this afternoon
with scattered showers falling to the north of the boundary. South
of the warm front, temperatures will soar to around 70 this
afternoon, with some breaks of sunshine. This frontal boundary
will stall across the region through the weekend, with several
periods of moderate to heavy rain and also areas of freezing
rain north of the boundary. One last area of heavy rain and
possible thunderstorms will cross the region Sunday night and
Monday, which may result in flooding.
&&
.NEAR TERM /THROUGH TONIGHT/...
A warm frontal boundary near the Pennsylvania state line late this
morning will push north into the Southern Tier. The front will then
stall across the Boston Hills, and the hills of Wyoming county and
southern Livingston County by late this afternoon. South of the
boundary temperatures will soar into the 60s (and near 70F right
near the Pennsylvania state line, with some breaks of sunshine.
To the north of the front, a much different outcome for this
afternoon with cloudy skies, scattered light showers and
temperatures ranging from around 40F on a northeast wind along
the southern Lake Ontario shoreline, to the lower 50s near the
NYS Thruway. East of Lake Ontario and away from the lake
influences, temperatures will peak in the mid to upper 40s.
A tightening thermal gradient to the north of the warm front
will serve as a boundary for rain to increase through the
evening and overnight hours. This boundary will set up over Lake
Ontario, and points eastward. Overall rainfall tonight will
range up to a half an inch east of Lake Ontario. As a very
strong surface high nears western Ontario late tonight, a
southern push of shallow subfreezing Canadian air will filter
across the Saint Lawrence Valley. This will lead to a threat of
freezing rain in the predawn hours to northern Jefferson County.
A winter weather advisory, including freezing rain, will start
at 6 am for the North Country.
A northeast flow tonight will also promote a deck of low stratus
clouds and fog along the southern shoreline of Lake Ontario,
with patchy fog extending southward towards Erie, Genesee and
northern Livingston Counties.
South of the stalled frontal boundary aloft precipitation chances
will quickly lower, with just a 10% chance for rain tonight near the
NYS line.
Low temperatures tonight will dip to the freezing mark east of Lake
Ontario, with upper 30s and lower 40s across the Niagara Frontier
and Finger Lakes region...to mid to upper 40s across the So. Tier.
&&
.SHORT TERM /SATURDAY THROUGH MONDAY/...
There is a significant risk of a wintry mix of sleet and freezing
rain this weekend. It's location will depend on the location of
sharp frontal boundary which push south of Lake Ontario Saturday and
Saturday night before lifting back northward as a warm front on
Sunday. During this time, there will a brisk northeasterly winds
gusting to 40 mph south of Lake Ontario which may result in downed
tree limbs if there is ice accumulation on vegetation. This will
then be followed by moderate to heavy rainfall Sunday night into
Monday which will pose the risk for flooding early next week.
Freezing rain is unusual in April, but model guidance consistently
shows a nearly ideal set up for a wintry mix for roughly the
northern two-thirds of our cwa. It is tempting to discount model
guidance because of the date, however unusual late (and early)
season events can and do occur. Strong high pressure is forecast to
track from Ontario to Quebec this weekend, which will provide a
steady supply of cold air and sharpen a strong surface front.
Meanwhile, mid-level warm air advection will result in a classic
freezing rain sounding with a layer of +4 to +8 C over top of sub-
freezing air. Just north of this, it will be colder aloft (but
still above freezing) with significant sleet accumulation
possible. 00Z model consensus has trended a bit south/colder
with the front and now shows a risk of significant icing
extending well south of Lake Ontario. Both ice and sleet is a
risk in the North Country where surface temperatures will remain
below freezing for most of the weekend. Based on this, we will
issue a winter weather advisory for all areas expect the
Southern Tier. Depending on the position of the front, this may
have to be added. There also is a risk the North Country may
approach warning criteria.
Temperatures will cool during the day Saturday as the front pushes
southward. This will result in freezing rain or sleet across the
North Country with areas of freezing rain developing south of Lake
Ontario. Ice accumulation will probably be limited to vegetation due
to warm soil temperatures. The front is expected to stall near the
NY/PA border Saturday night before lifting rapidly northward Sunday
as the surface low gets closer and provides a push. The greatest
risk for icing is Saturday night when strong April diurnal
influences will not be in play. During this time, northeast winds
will gust to 30 to 40 mph south of Lake Ontario which may result in
downed tree limbs in locations where there is icing. Temperatures
will warm from south to north quickly on Sunday, with sub-freezing
temperatures lingering the longest in the Saint Lawrence Valley.
Our concerns shift considerably after this as stacked low pressure
is expected to slowly move across the region. The sharp trough with
this system will tap into Gulf of Mexico moisture, with a period of
moderate to heavy rainfall expected Sunday night into Monday. Even
some thunderstorms are possible with 1-2 inches of rain likely. This
may cause flooding, which will be discussed in more detail in the
hydrology section. Precipitation will taper to showers from west to
east during the day Monday. Temperatures will continue to warm east
of Rochester Sunday night, into the upper 40s to lower 50s by
daybreak Monday. Then it will cool into the lower 40s behind the
system Monday afternoon.
&&
.LONG TERM /MONDAY NIGHT THROUGH THURSDAY/...
Monday night through Tuesday night the large far-reaching storm
system will pivot north and east into Quebec or across the Canadian
Maritimes. Strong cold air advection behind the system will hold
temps 10-15 degrees below normal. Overnight temps will dip down to
or below freezing Monday night then only recover into mid to upper
30s Tuesday before dipping back down to around freezing again
Tuesday night. Expect wrap around moisture behind the low to
continue to generate widespread chance probabilities for rain and
snow showers through Tuesday night. The airmass may grow just cold
enough (-8C to -10C at 850mb Monday night and Tuesday morning for
some enhancement from the lakes where likely probabilities have
been included.
By Wednesday, the spring storm should be well removed from western
and central NY where many locations will see some dry time before a
fast moving shortwave trough shifting from the Pacific NW looks to
then reach the eastern Great Lakes by later Wednesday passing across
our region through Thursday. Chance probabilities for showers have
been included. The Pacific nature of this wave should mean milder
air will arrive but highs at this point on Wednesday and Thursday
are still forecast about 5-10 degrees below normal.
&&
.AVIATION /15Z FRIDAY THROUGH TUESDAY/...
A warm frontal boundary across northern Pennsylvania will push north
into the Southern Tier of New York this afternoon. Scattered light
showers will pass across areas to the north of the front. For the
most part, VFR cigs and vsbys will persist. The exception will
be at KIAG and KROC where a developing northeast wind flow will
bring a deck of MVFR/IFR stratus off Lake Ontario, reaching
KBUF tonight.
All TAF sites will deteriorate to IFR tonight as rain increases
over the area along and north of the front. The front will
likely be north of KJHW, with VFR cigs expected there.
Outlook...
Saturday through early Sunday morning...MVFR/IFR with rain across
the Southern Tier, and freezing rain possible farther north. Some
sleet possible across the North Country.
Later Sunday through Tuesday...MVFR/IFR with periods of rain.
&&
.MARINE...
Winds and waves will remain below SCA thresholds this afternoon and
into much of tonight.
An area of low pressure will deepen and move closer to the eastern
Great Lakes from the Plains tonight. This will freshen northeast
winds which will build waves to SCA levels. Winds will continue
to increase with possible Gales on the western waters of Lake
Ontario Saturday and into Sunday morning. Elsewhere an extended
period of SCA is likely on the lakes, and also the Niagara
River.
&&
.HYDROLOGY...
There is a risk for flooding in the Sunday night through Tuesday
timeframe. Total rainfall amounts of 2 to 4 inches are likely, with
model consensus showing the greatest amounts are likely to be along
or north of the I-90 corridor. Some of this, may fall as frozen
precipitation but warmer temperatures Sunday into Monday are likely
to melt this and possibly some of the existing snow pack in the
Black River basin. MMEFS ensembles suggest that there is a
significant risk for flooding for many of our rivers and creeks. A
Flood Watch may be needed for all or part of the area if model
guidance continues to show this much rainfall.
&&
.TIDES/COASTAL FLOODING...
Northeasterly winds will result in significant wave action
which may result in lakeshore flooding and erosion along the
southwestern shores of Lake Ontario. A lakeshore flood watch was
issued for Niagara, Orleans, and Monroe counties.
