Area forecast discussion, Sep 25, 1:17 PM EDT, 1 hour 19 minutes before
Area Forecast Discussion
National Weather Service Buffalo NY
117 PM EDT Sun Sep 25 2022

.SYNOPSIS...
A very wet pattern will continue through midweek as low pressure
lingers for several days across southern Ontario and Quebec. This
will bring periods of showers areawide and heavy lake effect rain at
times east of Lake Erie and Lake Ontario with localized flooding
possible. High pressure will finally build into the Great Lakes
Thursday with a return to dry weather for late week.

&&

.NEAR TERM /THROUGH MONDAY/...
...SIGNIFICANT LAKE EFFECT RAIN WITH LOCALIZED FLOODING POSSIBLE
EAST OF LAKE ERIE AND LAKE ONTARIO...

A deep longwave trough will become established across the Great
Lakes tonight through Monday, with a mid level closed low developing
near Georgian Bay. An east-west elongated surface low will
consolidate near Georgian Bay tonight, then drift east across
southern Ontario on Monday. 850MB temps will gradually drop to +5C
by Monday, and a pool of cool 700MB temperatures and deep moisture
will combine with warm lake temperatures to produce strong and deep
lake induced instability, with lake induced equilibrium levels
around 30K feet through the period. The heaviest rain amounts in
these strongly unstable early season lake effect rain events tend to
be right along the lakeshore as opposed to extending well inland.

From a synoptic standpoint, the first area of rain associated with
warm advection and moisture transport ahead of the system will
continue to cross the eastern Lake Ontario region this afternoon and
exit the area this evening. Tonight through Monday, DPVA and height
falls ahead of the digging longwave trough will support occasional
showers at times. The main story will be lake effect potential, as
outlined below...

Off Lake Erie...

The area of organized lake effect rain over and east of the lake
early this afternoon will likely move east/inland and weaken through
the rest of the afternoon as subsidence and shear temporarily
increase behind a departing shortwave. Diurnal influences will also
tend to break apart banding structure during the afternoon hours.

Tonight through Monday a series of low amplitude shortwaves will
move through the longwave trough. Each of these will enhance the
Lake Erie lake effect, but also modulate intensity and location,
making the fine details of the forecast difficult. The very strong
and deep instability over the lake combined with passing shortwaves
may keep the lake effect showers more convective and cellular in
nature, but nonetheless capable of producing locally heavy rainfall.

Expect lake effect rain to become better organized again later this
evening, initially east of the lake across Chautauqua and southern
Erie counties. An approaching shortwave will then back the boundary
layer flow to the southwest by early Monday morning, with lake
effect rain centering on the Buffalo Metro area. From late morning
through Monday evening expect most of the heavier lake effect
showers to hug the Lake Erie shore from Chautauqua County northeast
to near Buffalo. Passing shortwaves will continue to modulate flow
and convective depth, so expect lake effect rain organization and
intensity to wax and wane numerous times through the period.

Rain amounts will reach 1-2" with locally higher amounts near Lake
Erie tonight through Monday evening, with additional rainfall after
that as outlined in the short term section below. The risk for
flooding will increase with each successive wave of rain as the
ground saturates.

Off Lake Ontario...

The position of the mid level low is not as favorable for a robust
lake response through Monday evening. There will be some lake
enhancement east and northeast of the lake from later this afternoon
through tonight, centering on the Tug Hill initially this evening
and then drifting north into Jefferson County overnight.

On Monday a digging shortwave upstream will back the boundary layer
flow to SW or even SSW, shortening the effective fetch over the lake
and pushing any lake effect rain north to the Saint Lawrence or even
into Canada at times. The shortened fetch and less favorable
climatological position of the mid level low will reduce the chance
of heavy lake effect rain through Monday evening east of Lake
Ontario. This will change by Tuesday, more on that in the short
term section below.

&&

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/...
Monday night and Tuesday, the stacked low heads northeast into
southern Quebec. More of a lake component to the overall
precipitation pattern (although there still will be showers
inland) should be realized during this period, as better over-
lake instability develops given the continued cooling aloft
being sent down on the backside of the low. A general west-
southwest flow Monday night will eventually veer more westerly
Tuesday sending the focus for heavier rain (along with
thunder/lightning) to east of the lakes. This will especially be
the case east of Lake Ontario where significant rain rates
could occur. Total rainfall amounts during this period could be
as heavy as 1.5-2.5". If these amounts are realized localized
flooding would certainly be a possibility and will need to be
monitored.

Secondary cold front crosses the region first half of Tuesday night.
This will likely take the ongoing lake bands and push them onshore
south of both lakes just ahead of it. There will be a brief lull
behind the boundary before lake effect activity then gets going
again overnight, this time to the south and southeast of both lakes
on a NNW/NW flow. This will lead to a multi-band setup with more of
a "spray" of lake effect rain showers. However, if and where a Lake
Huron/Georgian Bay connection can become established, expect some
better focused lake effect rains. Expect enhanced upslope flow along
N and NW slopes as well.

&&

.LONG TERM /THURSDAY THROUGH SATURDAY/...
Thursday we will still be under cool cyclonic flow as the upper
level trough exits out over Atlantic Canada. Meanwhile in the lower
levels surface high pressure will be building in from the west. We
could still see lake clouds...and an isolated rain shower south of
Lake Ontario early Thursday before drier air from the west wins out
and skies begin to clear. Clear skies Thursday night will allow for
another cool night with overnight lows in the mid 30s...to lower 40s
near the lakes. Inland frost is quite the possibility with light
winds.

This surface high will bring fair weather Friday...and possibly into
the start of next weekend. The forecast for next weekend will
heavily depend upon the track and timing of tropical system
Ian...which will move into an area of weak riding aloft over the
Northeast. Thus still a bit of uncertainty to any direct impacts to
our region.

&&

.AVIATION /17Z SUNDAY THROUGH THURSDAY/...
Low pressure will move very slowly east across southern Ontario and
Quebec through the first part of the week. This will bring an
extended period of unsettled weather and flight restrictions to the
eastern Great Lakes. The low and associated mid level trough will
produce occasional showers across the region. Cool air aloft will
support areas of lake effect rain over and east of Lake Erie and
Lake Ontario at times through Monday and beyond.

Widespread stratus and stratocumulus will produce areas of MVFR CIGS
at lower elevations and IFR higher terrain this afternoon through
Monday morning. CIGS will improve somewhat Monday afternoon with
mainly VFR lower elevations and MVFR higher terrain and in bands of
lake effect rain. Heavier showers in lake effect areas will bring
MVFR/IFR VSBY at times.

Outlook...

Monday night through Tuesday night...Areas of MVFR with local IFR.
Occasional showers and lake effect rain.
Wednesday...Areas of MVFR with scattered showers and lake effect
showers.
Thursday and Friday...Mainly VFR.

&&

.MARINE...
Increasing southwest winds will bring very choppy conditions to Lake
Erie this afternoon and evening. Low pressure will move slowly east
across southern Ontario and Quebec tonight through Tuesday, setting
the stage for an extended period of Small Craft Advisory conditions
on Lake Erie and Lake Ontario tonight through at least Tuesday
night with WSW winds in the 15-25 knot range, with higher gusts.

Cool air aloft and favorable conditions for lake effect rain will
continue to produce a chance of waterspouts through Wednesday.

&&

NY...None.
