this morning will change to snow as cold air moves in across the
region. Lake effect snow along with blowing snow will cause travel
issues in some areas today. High pressure moves in for Friday before
the next area of low pressure causes a mixture of snow, sleet and
rain over the weekend. Cooling temperatures from Sunday through the
middle of next week will bring daytime highs below normal.
&&
.NEAR TERM /THROUGH TONIGHT/...
Rain showers are currently falling across WNY and the Northern
Finger Lakes with some snow mixing in, especially the northern areas
where cold air has filtered south into those locations. Temperatures
are currently in the mid to upper 30s across the area, but are
slowly cooling as cold air advection begins. Temps in the North
Country are in the low 30s, but most of the precip with the main
area of low pressure over WNY is south of the I90/I81 area. Some
precip is across the far northern portion of the North Country and
anything that is reaching the ground is in the form of light snow.
This area of snow is associated with a shortwave trough crossing the
area from the northern Great Lakes.
The area of low pressure over WNY will continue to track east to New
England and the Gulf of Maine through the morning, before tracking
out to sea through the remainder of today, strengthening as it
tracks east. North of this area of low pressure, and just north of
Lake Ontario this morning a weak cold front/ mid level trough that
will drop south across the area later this morning. Weak cold air
advection behind the passing low pressure will slowly cool
temperatures and change rain to a mix of rain and snow and then snow
from the higher elevations to the lower elevations through daybreak.
As the front/trough crosses the area increasing cold air advection
will continue to see temperatures drop today. Most locations across
the area should see all precipitation change over to snow by the
morning commute.
With the passing trough widespread snow showers will develop across
the area from just before daybreak through the mid morning time. A
tightening pressure gradient behind the passing low and an
approaching area of high pressure from the west will cause winds to
increase this morning and afternoon. Combined with falling snow,
winds will cause areas of blowing snow and drifting of snow through
the day as snow falls and temperatures cool. Snowfall for areas with
general widespread snow and then some lake enhancement should
generally be around 1 to 4 inches with most of this snow falling
through the late morning. As temperatures cool, a lake response will
develop off of both Lake Erie and Lake Ontario. 850H temps will cool
from around -6C early this morning to -10C this afternoon and to
around -15C by the evening. As the 850H temps cool precip will
transition from synoptic to lake and orographic enhanced to lake
effect through the day.
Off of Lake Erie, the northwest flow combined with lingering
synoptic moisture will create a Lake Huron to Lake Erie connection
with a multi band setup initially along with orographic lift across
the Western Southern Tier and Wyoming and Southern Erie counties. As
synoptic moisture decreases later in the afternoon and into the
evening, some of the weaker bands will dissipate and a singular band
should develop downstream of the best convergence over Lake Huron
extending across Lake Erie. The lake response will weaken through
the evening into tonight off of Lake Erie as increased ridging from
an approaching area of high pressure lowers equilibrium heights in
addition to decreasing synoptic moisture from the departing trough.
Southeast of Lake Erie, snowfall amounts of 4 to 8 inches can be
expected with the best snow amounts across the higher terrain and
where the lake snow band sets up for the longest.
Off of Lake Ontario, lake enhancement through the early afternoon
will transition to purely lake effect southeast of the lake as the
northwest flow brings a Georgian Bay connection across the lake and
onshore. Areas from eastern Wayne to western Oswego counties should
see the greatest focus of the lake band as the ~310 degree flow
concentrates the band in this area. Equilibrium heights southeast of
Lake Ontario will also drop off through the evening into the
overnight tonight as ridging increases and the synoptic moisture
decreases. Snowfall amounts under the most persistent snows will be
around 4 to 8 inches southeast of Lake Ontario. The Tug Hill can
also expect around 4 to 8 inches due to earlier terrain enhancement
with the synoptic snow and lake enhanced snow after. Lake effect
snow will linger through the night along the south shore of the lake
where the lake may provide just enough moisture through the night to
continue light snow.
Temperatures today will have an early day high in the upper 20s to
low 30s and drop to the upper teens to mid 20s by the late
afternoon.
Tonight, outside of the linger light lake effect snow, some snow
showers will be possible across the area with only a few tenths of
an inch of snow expected. Temperatures tonight will be in the single
digits below zero east of Lake Ontario and in the upper single
digits to low teens south of Lake Ontario. Winds tonight will weaken
through the night as the area of high pressure approaches from the
west and the tight pressure gradient relaxes.
&&
.SHORT TERM /FRIDAY THROUGH SUNDAY/...
Weak northerly flow persisting just ahead of the approaching
surface and 850 mb ridges should maintain at least some weak
lake effect/upslope snows into Friday. The activity should be at
a minimum by midday, but probably not completely done until
mid/late afternoon. Additional snowfall amounts will be minimal
and likely under an inch. Much colder air will continue to
spread into the region, with temperatures barely getting out of
the teens and probably remaining in the single digits east of
Lake Ontario, making Friday the coldest day in nearly a month.
Wind chills below zero during the morning only improving into
the single digits by afternoon.
Friday night, all models are dry with the ridge axis sliding
into the area leading into the weekend system. It should be
even colder than Thursday night as winds drop off as surface
high shifts just past the region. The coldest readings will be
east of Lake Ontario possibly as cold as 10 to 15 below,
increasing clouds farther west will keep readings up a bit.
Attention then turns to the next system moving in on Saturday.
The surface low is expected to track through the Midwest into
the Great Lakes on Saturday with 00z guidance fairly consistent
in a track through northern/central Lower Michigan into Ontario.
A southwesterly low level jet of nearly 50 knots will transport
abundant moisture into the area. With a cold layer in place,
snow will quickly ramp up Saturday morning. Steady snow will
likely remain through the day for eastern areas, with even a
period of heavier snow, when strong lift intersects with the
optimal snow growth producing possible snowfall rates up to at
least an inch per hour for a time. Several inches of snowfall
should accumulate by evening.
Farther west, an elevated warm layer will push in with a period of
mixed precipitation developing, with areas closer to the Lake
Erie shore including Buffalo likely transitioning over to all
rain for a time as surface temperatures go well above freezing.
This transition will greatly limit snowfall amounts.
As the trailing cold front pushes across the area Saturday
evening and night, cold air will come rushing in, and soundings
will quickly become drastically unstable in the lower levels. A
nice push of differential PVA works with these lapse rates to
probably yield a quick push of snow along and just behind the
front for everyone before moisture peels off and lake effect
becomes the predominant issue. As this occurs, and concurrent
with the cold frontal passage, wind off the deck starts to ramp
up toward 50 kts, and given unstable low level lapse rates, this
will yield a wind post-frontal period across the area. However,
given the exceedingly wet snow ahead of the front, it probably
will take a bit before blowing snow would become a concern, and
most areas other than the inland North Country will not have
seen enough snow to make blowing snow an issue until late into
Saturday night.
As lake effect ramps up in cold advection overnight Saturday
night into Sunday, the Lake Erie band will start near Buffalo
then wander southward as the boundary layer cools. Quick wet
accumulations may be possible in Buffalo before the much more
efficient snows drift with the band toward the Boston Hills and
points southward. SLRs rapidly ramp up toward 20:1 as this
occurs, as well. Similarly, the same thing happens east of Lake
Ontario on Sunday, with a dominant band likely east of Lake
Ontario to dump high ratio lake snows on and near the Tug Hill.
Headlines in both locations will be likely.
&&
.LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/...
Lake effect snows will continue east of the lakes for much of
the early portion of next week as cold continues to reside and
pinwheel across the Great Lakes. What's interesting about this
pattern is while the ensembles all yield a few days of cold air,
the formation of a coherent Hudson Bay low is utterly lacking,
thus while the long term portion of the 7 day remains cold, it
would seem difficult for it to be entrenched much beyond that as
there is no large scale forcing for longitudinal transport of
cold air into the eastern CONUS.
&&
.AVIATION /10Z THURSDAY THROUGH MONDAY/...
Weak low pressure currently crossing the area with an area of
rain, mixing with snow from KROC to KART, with cigs IFR/MVFR.
The rain or rain/snow mix will change to widespread snow with
areas of blowing snow this morning with prevailing IFR to MVFR
cigs and vsby. Brief LIFR vsby could occur during heavier snow
showers. In the wake of the low pressure system, strengthening
winds from the northwest are also expected with gusts over 25
knots common at the TAF sites mid morning onward.
The snow will diminish to scattered lake effect snow showers late
this afternoon into tonight with mainly MVFR cigs and visibility,
though brief IFR visibility will occur in heavier lake effect snow
showers southeast of the lakes.
Outlook...
Friday...A chance of snow showers early with local MVFR/IFR,
otherwise VFR.
Saturday...MVFR/IFR with snow, possibly changing to a wintry mix
across Western NY.
Sunday and Monday...MVFR/IFR due to lake effect snows and blowing
snow east of the lakes.
&&
.MARINE...
Low pressure over the area this morning will track toward New
England and the Gulf of Maine through the morning, strengthening in
the process. West to northwest winds will rapidly increase in the
wake of this system this morning, with Small Craft Advisory
conditions on both Lakes Erie and Ontario. The winds will slowly
diminish from west to east tonight, then become light on Friday as
high pressure builds over the eastern Great Lakes.
