Area Forecast Discussion
National Weather Service Cleveland OH
107 AM EST Tue Jan 19 2021
.SYNOPSIS...
A surface trough over Lake Erie will move northeast tonight. Low
pressure over Lake Superior will move southeast through the
Great Lakes region on Tuesday and extend a cold front across the
area. High pressure will enter from the southwest on Wednesday.
A low pressure system will impact the Great Lakes region for the
end of the week.
&&
.NEAR TERM /THROUGH TODAY/...
The lake effect snow band has been disrupted temporarily as flow
wavers with time across the area. However, expecting lake effect
band to redevelop overnight across northwest Pennsylvania. The
snow will be light through the day Tuesday but increase in
intensity by Tuesday evening. Will need to monitor this area
again for additional headlines. Since the snow band pretty much
dissipated, will go ahead and drop the lake effect snow warning.
Otherwise, some very light snow is being reported in a few
locations in response to positive vorticity advection and
associated moisture moves into the region. Very light
accumulations of snow expected overnight.
Temperatures still hovering in the upper 20s to lower 30s this
evening but should drop into the middle and upper 20s by
morning.
Previous discussion...
Much of the attention for the near term forecast has been for
Northwest PA today. A potent snow band developed over Lake Erie
this morning and brought hours of moderate to heavy snow to Erie
County PA through this afternoon. This band is still bringing
impactful snowfall to portions of Erie County but is pivoting
northward as a slight low-level ridge axis enters the Lake Erie
basin and slightly enhanced southerly flow is allowing for the
band to lift over Lake Erie and into western New York. The
thermodynamic environment is still marginal across the eastern
Lake Erie region, but strong surface convergence seems to be the
main forcing mechanism to keep this band going. With that,
expect the moderate to heavy snow to only last for the next
few hours, mainly in northeast Erie County PA and expect only 1
to 3 more inches with perhaps an isolated 4 near the NY State
Line. Elsewhere, some scattered snow showers remain across the
region as a weak wave of vorticity moves through the area.
Accumulations will be light and less than an inch for most
folks. An inch is possible downwind of Lake Erie in NE
OH/Crawford Co PA where snow may try to persist a bit longer
into the evening. For the overnight, trends are drier generally
speaking. There will be lake effect snow near NW PA but most of
the action should be over the lake but have some likely PoPs
into the Erie area for glancing showers further south. A weak
wave is expected to move through the Ohio Valley, but snow
appears to remain further south where the better jet energy will
stay and have only slight chance PoPs at best. Temperatures
through the overnight will not fall all that much just into the
upper 20s. The forecast area appears to remain between low
pressure systems for Tuesday and will keep the forecast mostly
dry with the exception for some scattered lake effect snow
showers in NW PA. Widespread cloud cover will remain across the
area with good low level moisture remaining in place and
temperatures will only marginally rise into the low 30s.
The next forecast concern for the area will be on Tuesday night.
A low will move southeast through the Great Lakes region on
Tuesday and extend a cold front across the area. This front will
allow for snow to become focused on Ohio and PA once again as
mean flow will shift to the west then northwest. With the front
itself, expect a good push of snow to enter the region with
convergence and low level lift over NE OH and NW PA, all
coinciding with the entrance of a mid-level vorticity max
across the region. Then, with the more favorable flow off Lake
Erie, expect lake effect/enhancement to return as snow persists
later on Tuesday night into Wednesday. The thermodynamic
environment over Lake Erie on Tuesday night seems better than
the environment that brought the snow today into NW PA. 850 mb
temperatures will cool to -10 to -12 degrees Celsius, resulting
in lake sfc-850 delta Ts of 13 to 14 C, which should allow for
some conditional instability across the region and more intense
bands of snow should develop into NE OH and NW PA on Tuesday
night into Wednesday. With increasing confidence in snow with
multiple forcing mechanisms and additional confidence with recent
guidance, have bumped QPF and snow totals for Tuesday night
with a maximum of 4 to 6 inches in Erie County PA and then 2 to
4 inches in NE OH and Crawford County PA. At this point, it
seems likely that another winter weather headline will need to
be issued for portions of PA for Tuesday night and perhaps
additional areas into OH. With ongoing headlines for PA, won't
issue anything with this package and maintain the mention in the
Hazardous Weather Outlook.

.SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/...
The upper-level trough will largely be east of our forecast area
with the western edge of vorticity maxima located over northwest
Pennsylvania and eastern Lake Erie by 12Z Wednesday. While coverage
of snow will be decreasing through the day Wednesday, there could
still be some intense snow bands during the morning hours despite
the loss of upper-level forcing and deeper moisture. This is because
a cold airmass behind the trough will result in conditional
instability and fairly steep low-level lapse rates, especially below
850 mb. This opportunity for localized higher snow rates will mainly
be reserved for the morning hours across parts of northeast Ohio and
northwest Pennsylvania. While transitioning to a more traditional
lake effect snow, coverage and intensity of snow will gradually
diminish due to decreasing inversion heights and warming
temperatures aloft as an upper-level ridge approaches from the west.
The ridge will works its way east across the forecast area Wednesday
afternoon/evening with any lake effect snow out of the area by late
Wednesday evening. Additional snow accumulations during the day
Wednesday are expected to be around an inch or so with locally
higher amounts possible where more intense snow showers/bands linger.
Meanwhile, an upper-level shortwave trough will move from the
Canadian Prairies on Wednesday to eastern Ontario by Thursday. The
associated occluded low will move from Lake Winnipeg on Wednesday to
northeast of Lake Superior by late Thursday, weakening a by around
10 mb from ~985mb to ~995mb. This will result in a weak front, very
quickly followed by a weak cold/occluded front bringing light
rain/snow showers late Wednesday night and during the day Thursday,
mainly for northwest Pennsylvania.
Temperatures on Wednesday will be rather chilly with highs at or
below 30. Temperatures will actually increase Wednesday night with
the aforementioned warm front, allowing temperatures to increase
into the upper 30s to low 40s for much of the area Thursday
afternoon, likely the warmest day of the entire forecast period.
Temperatures decrease back into the 20s Thursday night.
&&
.LONG TERM /FRIDAY THROUGH MONDAY/...
Northwest flow that develops Thursday night is expected to continue
through the long term forecast period, with below normal
temperatures expected. The aforementioned low continues to move
eastward to the New England Coast by Friday. Several upper-level
shortwave troughs will move southeast across the region through the
weekend, bringing cold air aloft across the Great Lakes region. This
will result in an extended period of lake effect snow from through
at least Saturday. However, there is some uncertainty with the
evolution of shortwave troughs and intensity of cold air aloft,
resulting in uncertainty with duration, intensity, and location of
lake effect snow. Most models have at least 12-24 hours of 850mb
temperatures of -14 to -16 C with northwest flow, which could
produce a moderate amount of snowfall for much of the lake effect
belt over the weekend. Details will become clearer in the coming
days. Upper-level ridging and subsequent surface high pressure is
expected to build into the region Saturday night and Sunday.
Uncertainty is high for Monday onward, but many models are hinting
at a deepening low pressure system somewhere in the central CONUS
bringing precipitation to our area.
&&
.AVIATION /06Z Tuesday THROUGH Saturday/...
Generally MVFR stratus continues to linger at the terminals at
the onset of the period. Some improvement expected with VFR
conditions becoming common at terminals after 12Z-15Z. Snow may
impact eastern terminals through the first half of the period,
most likely at KERI where a lake effect snow band may push back
onshore near 12Z. A quick moving trough will approach the area
from the northwest towards the end of the period, bringing MVFR
conditions and more SN at the end to just beyond the forecast
period. Southwest winds will persist through the period, with a
few 20 kt gusts possible this afternoon, and will become more
westerly near the end of the period.
Outlook...Non-VFR possible through Wednesday morning in the
northeast. Non-VFR possible Friday and Friday night and then in
the northeast Saturday.
&&
.MARINE...
Wind speeds on Lake Erie are in a bit of a lull right now but are
expected to increase to near 20 knots later this evening. Southwest
winds of 20 to 25 knots are expected to last through Wednesday. A
Small Craft Advisory in effect for nearshore zones east of Willowick
through 00Z Thursday, with nearshore zones between Vermilion and
Willowick not beginning until Tuesday evening. Winds dip below 20
knots Wednesday evening as they become more northwesterly but that
will be fairly shortlived as they are expected to strengthen again
with southwest winds Wednesday night onward.
