Area Forecast Discussion
National Weather Service Buffalo NY
730 PM EDT Wed Aug 31 2022
.SYNOPSIS...
A secondary cold front will cross the area through this evening,
producing a few scattered showers and possibly a thunderstorm
east of Lake Ontario. A few more lake effect rain showers will
then develop tonight east and southeast of the lakes before high
pressure brings a return to dry, cooler, and less humid weather
Thursday. A warming trend is then expected Friday and Saturday
leading into the Labor Day weekend.
&&
.NEAR TERM /THROUGH THURSDAY/...
Winds will quickly drop off this evening. Sharp secondary cold
front now pushing south across Lake Ontario will move south
across Western New York this evening. With the loss of daytime
heating surface based instability will diminish with showers and
embedded thunderstorms weakening through the evening hours.
There's a small chance that the upper level trough and steep
lapse rates will support a few gusty thunderstorms east of Lake
Ontario into this evening.
Colder air aloft spreads in behind the frontal passage tonight,
creating favorable conditions for some lake effect showers. The best
coverage of showers will be east/southeast of Lake Ontario where
better synoptic moisture and forcing will be found. Expect a band of
lake effect showers to reach peak organization over Oswego County
and the southern Tug Hill by late this evening, then break apart
into scattered showers that drift south to areas southeast of the
lake overnight as boundary layer flow veers northwest. Off Lake
Erie, less available moisture and forcing will likely limit the
lake response, with scattered showers across the higher terrain
east of the lake peaking in coverage mid to late evening before
ending overnight.
Thursday, any remaining isolated showers southeast of Lake Ontario
will end in the morning. Lake effect clouds southeast of the lakes
will initially transition into a diurnal cumulus field by late
morning before scattering out and giving way to more sunshine in the
afternoon as the remaining shallow moisture mixes out and high
pressure builds into the eastern Great Lakes.
&&
.SHORT TERM /THURSDAY NIGHT THROUGH SUNDAY/...
High pressure will cross our region Thursday night, with fair
weather across the region. Light winds associated with the surface
high and longer September nights will be favorable for some valley
fog in the Southern Tier and Black River Valley.
Southerly flow behind this surface high will advect a milder airmass
into our region...one that will progressively become more humid also
by Saturday. Highs Saturday will be 8 to 10F degrees above early
September normals.
An upper level trough will pass by just to our north Saturday night
and Sunday...while a shortwave slowly advances northward up the Ohio
Valley. This upper level trough will push a cold front across our
region late Saturday Night and Sunday, that combined with additional
lift from the Ohio Valley shortwave will bring scattered showers and
possibly a thunderstorm.
A touch of mugginess late Saturday Night and Sunday will slowly be
replaced by a drier and more comfortable airmass from north to south
through the afternoon hours as precipitation slides off to the
southeast.
&&
.LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/...
A few scattered showers may linger Sunday night in the wake of the
cold front that moved through on Sunday owed to its' anafrontal
characteristics, especially south.
Heading into the start of the new work week, there will be a small
chance for a few showers Monday afternoon as a weak upper level
shortwave moves through during peak heating. That said, latest model
trends have shifted this shortwave a bit further to the northeast,
which could possibly mitigate any shower chances. For now will keep
SChc to low Chc PoPs in the forecast until there is better run to
run consistency with this feature. Otherwise, strong Canadian
sourced high pressure will keep the boundary that passed through on
Sunday stalled somewhere near the Mason-Dixon Line through mid week,
while a weak upper level low circulation tries to close off over the
mid Mississippi/Ohio Valleys under a building eastern CONUS ridge.
All in all still appears there could be a few scattered showers on
any given afternoon across southern NY through mid week with the
eastern periphery of the weakness in the upper levels residing just
southwest of the area. Otherwise, mainly dry conditions expected.
Temperatures will remain a bit above average for the first part of
September with highs generally ranging through the 70s areawide
through the period.
&&
.AVIATION /00Z THURSDAY THROUGH MONDAY/...
Scattered showers and a few thunderstorms are possible as a
cold front pushes south across the area through this evening.
These are not likely to impact any of our terminals with most of
these east of Lake Ontario but south of KART.
Lake effect showers will then develop again tonight southeast
of the lakes behind the cold front, with the best coverage east
and southeast of Lake Ontario. VFR will continue to prevail,
with any MVFR limited to in and near lake effect showers.
High pressure will build in Thursday with widespread VFR flight
conditions developing by mid-day. A chance of lake effect rain
showers southeast of Lake Ontario during the morning.
Outlook...
Thursday night through Saturday...VFR.
Sunday...VFR/MVFR with a chance of showers.
Monday...VFR.
&&
.MARINE...
Cold advection and a decent pressure gradient will continue to
support strong westerlies into this evening with sustained winds
20-30 knots and gusts to near 35 knots. A secondary cold front
will pass south of the lower Great Lakes this evening.
Winds will become northwest tonight behind the cold front, then
gradually diminish by Thursday morning. Issued a Small Craft
advisory for the Lower Niagara River due to the increasing
northwest winds. Otherwise, Small Craft headlines and Beach
Hazards Statements will be maintained for our nearshore waters
and lakeshore beaches with timing as outlined below.
A much cooler airmass will remain over the lower Great Lakes through
Thursday. This will lead to an environment supportive of a chance of
waterspouts through Thursday morning. The best chance of waterspouts
will be in and near bands of lake effect clouds and showers where
convergent low level boundaries produce locally enhanced low level
vorticity, which can then be tilted and stretched by lake effect
updrafts.
