.SYNOPSIS...
High pressure will build east across the region today. Low pressure
originating near the Gulf Coast will extend a surface trough into
the Ohio Valley Monday night into early Tuesday, before tracking
northeast off the Mid-Atlantic Coast. High pressure will build east
across the region Tuesday night and Wednesday ahead of a cold front
that will push south across the area early Thursday.

&&

.NEAR TERM /THROUGH TUESDAY/...
Satellite imagery shows one remaining band of clouds extending from
Lake Huron with clearing skies across much of Lake Erie. Snow
showers are showing a downward trend in intensity across Erie
County, PA and the Winter Weather Advisory looks on track to expire
on schedule at 7 AM. The weather today will be quiet with high cloud
overspreading the area while stratocu remains across NE Ohio and NW
Pennsylvania.

Attention then turns to the trough swinging east across the Plains
today before lifting across Northeast Ohio tonight. At the surface
low pressure will originate along the Gulf coast and track northeast
towards the Mid-Atlantic through Tuesday. Before that occurs,
most models show an inverted trough extending north into eastern
Ohio and some high resolution models even depict a weak
secondary low tracking across West Virginia on Tuesday morning.
A considerable layer of dry air between 850-700mb spreads north
across the area this afternoon and will need to be overcome
before any precipitation reaches the ground tonight. Favorable
isentropic ascent spreads west to east across the area from
02-06Z with light snow developing. Snow is forecast to increase
in intensity towards 06Z as the shortwave trough approaches from
the Mid-Mississippi Valley and frontogenesis ramps up in the
850-700mb layer. Snowfall rates of a half to three quarters of
an inch spread northeast across the area generally between
midnight and 9 AM producing a few quick inches of snow. There
looks to be a banded component to this system which means a
swath of 3-6 inches is possible while areas outside this heavier
band could be a little lower than forecast in the 1-3" range.
Best guess at this point is for the heavier band to be in the
vicinity of Mount Vernon to Akron to Meadville, but this could
vary northwest or southeast by a couple tiers of counties and
have gone with a more broad brushed snowfall forecast. The
timing of the snow is more problematic from north central Ohio
to Northwest Pennsylvania as it will be falling late tonight and
into the morning commute on Tuesday. Intensity of snow will
drop off quickly from west to east on Tuesday morning as a dry
slot wraps into the system in the 700-500mb layer. Sometimes
these dry-slots are faster than expected as a 150 knot upper
level jet streak slides east of the area by 12Z and that will be
something to monitor. Liquid qpf is forecast to range from
around 2 tenths towards Toledo to 4 tenths across the snowbelt
region which is why portions of NW Ohio are not included in the
Advisory. Snow ratios of 10-14:1 will result in a widespread
2-5" of snow. Both the 00Z GFS and ECMWF are a little lower on
qpf while several of the high resolution models are hinting at
the banded precipitation developing and will favor some of those
solutions.

Deeper moisture pulls away on Tuesday morning which leaves some
question regarding lake effect snow potential in the northwesterly
flow continuing through the afternoon. Lift looks to be
shallow(below 5K feet) but models sounding off Lake Erie suggest
equilibrium levels of 7-8K over the lake which would have sufficient
depth for ice nuclei. Will keep 50-70 percent pops going across the
snowbelt Tuesday afternoon with additional minor accumulations of 1-
2" possible where bands set up. This was the reason for keeping the
Winter Weather Advisory in effect through 7 PM across the snowbelt
although the heaviest snow is expected during the early morning
hours.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/...
Flow backs on Tuesday night and any lingering snow showers should
diminish as moisture depth continues to dwindle. High pressure will
build east across the Ohio Valley Wednesday with partly cloudy
skies, southwesterly flow, and warm advection. Another upper level
trough will traverse the Great Lakes Region Wednesday night, pushing
a cold front south across the area. As moisture overspread Lake Erie
ahead of this system, lake effect snow showers will develop, then
push inland Wednesday night into Thursday AM. Snowfall amounts look
to be a half inch or less along the cold front except as high as 1-2
inches in the snowbelt south of Lake Erie. High temperatures on
Thursday will occur during the morning and fall during the
afternoon. With a brisk northwest wind, wind chills on Thursday will
be in the teens. Winds drop off Thursday night as high pressure
quickly builds in but allows for the coldest night of the year with
lows of 5-10 degrees except in the teens near Lake Erie.

&&

.LONG TERM /FRIDAY THROUGH SUNDAY/...
A cool pattern with below normal temperatures looks to continue
through the weekend. A broad longwave trough is in place from the
northern Plains to New England with poor model agreement with
regards to shortwave energy moving through the flow aloft. It looks
as if the storm track starts off south of the region and pops have
trended lower to start the long term. We will need to monitor trends
over the coming days for the potential for additional snow showers
in this cooler pattern.

&&

.AVIATION /12Z Monday THROUGH Friday/...
Mainly VFR across the TAF sites this morning with widespread
deterioration to IFR later this evening and overnight as snow
moves from west to east through the area. Confidence is highest
in vsbys falling between 1 to 2sm areawide, with a narrow
corridor of vsbys potentially falling as low as 1/2sm early
Tuesday morning.

Winds are generally light and variable this morning, less than 5
knots. Winds will gradually favor an easterly direction later
this morning and afternoon, 5 to 7 knots.

Outlook...Non-VFR likely in lingering low ceilings and/or lake
effect snow Tuesday night into Wednesday morning. Non-VFR likely
again Wednesday evening and overnight in snow along a cold
front. Non-VFR possible in scattered snow showers on Friday.

&&

.MARINE...
Quiet marine conditions are expected for the first half of this week
as weak high pressure and/or weak troughing persists over the
Lower Great Lakes region with winds less than 15 knots expected.
Small Craft Advisories will be needed across Lake Erie Wednesday
through Thursday as southwest winds of 25 to 30 knots arrive ahead
of a cold front on Wednesday, shifting towards the west to
northwest, 20 to 25 knots, behind the front on Thursday. Winds will
favor a southwest direction by the end of the week, 15 to 20
knots.
