.SYNOPSIS...
Lake effect snow showers will mainly be focused over north
central New York today, though a few stray snow showers may
reach northeastern Pennsylvania. A strong clipper system will
bring increasing chances for accumulating snow Wednesday
afternoon and Thursday, with colder air, gusty winds, and more lake
effect snow developing in its wake.
&&
.NEAR TERM /THROUGH WEDNESDAY/...
915 AM Update...
Current lake effect snow across Central NY still disorganized,
we extended chances for snow showers south more into the Finger
Lakes region. A more organized band is expected to form within
the next couple hours over Cayuga-Onondaga counties, bringing an
additional 1 to up to 3 inches through this afternoon.
425 AM Update:
Disorganized lake effect flurries and snow showers continue to
stretch from the southern Finger Lakes into NEPA. Radar
indicates Lake Ontario is starting to reawaken again ahead of a
surface trough stretched across the Ontario peninsula. Lake
effect snow bands over the past couple of days have not been
terribly well organized or well-behaved, and today is likely to
be similar. The main focus for light accumulation still looks to
be across north-central NY, including Cayuga, Onondaga, and
Madison Counties, with models favoring the southern half of the
counties through this morning, with snow showers ramping up
after sunrise. Considering trends, especially yesterday, we kept
the chance for brief snow showers over a broader area this
morning. With a shortwave trough approaching late this
afternoon and early evening, and enhanced upper level
diffluence in the left-front quad of a 110+ knot jet streak, we
also kept slight chance PoPs in place across much of south-
central NY and parts of the Northern Tier of PA despite most
models keeping things precip-free. Don`t be surprised if a few
renegade snow showers from Lake Erie work their way in before
low level winds shift to the WSW and SW later tonight.
We`ll keep the Advisory going through this morning, though
additional snowfall amounts look to be in the 1-3 inch range
where lake effect bands are most persistent.
Remaining LES bands will shift north of the area after midnight
as our approaching clipper system dives into NW Ontario.
Low level warm advection and a few weak shortwaves embedded in
increasing upper level westerlies will help kick off more snow
showers Wednesday afternoon, mainly over Central NY, with the
higher elevations of the Allegheny Plateau and northern Oneida
County most favored due to orographic effects in increasing
southerly flow. Despite the wind direction, 850 temps will
remain around -8 to-10C even in the afternoon. Surface
temperatures will rise into the middle-30s in the lower
elevations, with higher elevations (most prone to orographic
snow) staying near or below freezing. Either way precip type
looks to be mostly snow even in the valleys. Accumulations Wed
afternoon through early evening will generally be up to 1 inch
across the Allegheny Plateau (north of the Susquehanna and
south of the Thruway/Lake Plain) and up to 2 inches in northern
Oneida County.
&&
.SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/...
455 AM Update...
A potent clipper system will move across the northern Great
Lakes Wednesday night and push east Thursday with the low track
passing by just north of the CWA before reaching New England by
Thursday afternoon. This system is expected to lead to
widespread light to moderate snow showers Wednesday night into
early Thursday then once a strong cold front associated with
this system pushes through Thursday morning, there will be a
transition to lake effect snow showers Thursday afternoon into
Thursday night. With the low deepening as it moves east and the
pressure gradient tightening over the area, strong winds are
expected to develop Thursday into Thursday night with gusts of
35 to 45 mph possible during the day Thursday with potentially
locally higher gusts. Along with the strong synoptic winds, as
the strong front goes through early Thursday morning, steep low
level lapse rates are expected to be in place and even some
modest amounts of instability, so there is the potential for
some snow squalls. Overnight lows Wednesday will be in the 20s.
High Temperatures Thursday were lowered a bit from the NBM by
blending in the NBM50th percentile with the strong cold air
advection behind the front leading to highs in the upper 20s and
low 30s. Lows Thursday night drop back into the teens and low
20s with continued lake effect snow showers, mainly over CNY.
Factoring in the gusty breeze, "feels like" temperatures can
fall into the single digits and lows teens before daybreak
Friday morning.
With regards to headlines, a Winter Storm Watch has been issued
for Northern Oneida County beginning Wednesday afternoon with
the onset of warm advection snow and enhancement due to
orographic lift with southerly flow initially in place, and
lasts into later Thursday night with the transition to lake
effect snow. Confidence is highest here at this time for 7
inches or more of snowfall during this period. Areas farther
south through the higher terrain of CNY will continue to be
monitored closely for the potential of additional headlines
especially as confidence increases with regards to lake effect
snow placement. Across NE PA, snow amounts Wednesday afternoon
through Thursday night look to generally be less than 2 inches.
&&
.LONG TERM /FRIDAY THROUGH MONDAY/...
1200 PM Update:
With a northwesterly flow and 850mb temperatures around -14C,
lake effect snow showers are expected on Friday, particularly
across Central NY. Then as the wind direction shifts to more of
a westerly direction, these lake effect snow showers are
expected to be more concentrated towards areas along and north
of the NY Thruway corridor by Friday night into Saturday. A weak
clipper system may bring some additional snow showers to the
area on Saturday, but it is possible that this could end up
being mainly north of our area.
Then weak ridging may finally bring mainly dry conditions to
the area on Sunday, along with warmer temperatures. An area of
low pressure passing by to our west then may bring some
additional precipitation by the Monday/Tuesday timeframe. At
this time, temperatures appear to be warm enough for the form of
precipitation to be mainly rain from this early week system.
Temperature-wise, continued below normal temperatures are
expected for Friday and Saturday (highs mainly in the mid 20s to
lower 30s), before a warm-up occurs starting on Sunday.
Temperatures on Sunday are expected to be near-normal (highs in
the mid 30s to lower 40s), before above normal temperatures are
anticipated for Monday and Tuesday with highs mainly in the 40s
and perhaps near 50 degrees in some of the valleys on Tuesday.
&&
.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
Lake effect snow is increasing downwind of Lake Ontario and will
continue to spread across north-central NY through the next few
hours. Conditions will deteriorate at SYR between 12Z and 13Z
with prevailing fuel alt and TEMPO IFR. The focus for steadier
snow is expected to drift south of the terminal later this
morning, with conditions improving to MVFR by midday, though off
and on snow showers can`t be completely ruled out.
Otherwise, expect a mix of MVFR to fuel ceilings with scattered
flurries and disorganized snow showers through the morning
across CNY. Brief IFR is possible in heavier showers but
probabilities outside of SYR and RME were too low to carry. ITH
and BGM have a slight edge over ELM.
Will need to keep an eye out for any renegade Lake Erie showers
making a run for AVP this afternoon, especially as an upper
level trough passes through. For now, this appears to be a low
probability event.
VFR will prevail overnight as lake effect snow shifts north as
southwest winds develop.
Outlook...
Wednesday...Between systems with predominant VFR conditions.
Light snow may try to redevelop by afternoon at SYR and/or RME.
Wednesday Night...Snow showers possible in Central NY ahead of a
clipper system, mainly focused on north-central NY. Restrictions
likely, southwest wind gusts approaching 20 knots.
Thursday...A low pressure system moving through Southern Canada
may bring scattered snow showers with lake enhancement, mostly
focused on central NY. Windy, westerly gusts 25-35 knots,
potentially even higher at times.
Friday...Lake effect on back side of low with restrictions
possible at CNY terminals, but improving by evening. Northwest
wind gusts approaching 20 knots.
Saturday... Some additional snow showers possible with
restrictions.
