Area Forecast Discussion
National Weather Service Cleveland OH
942 AM EST Sat Dec 14 2019

.SYNOPSIS...
Low pressure over southern West Virginia will move northeast
today and deepen rapidly. High pressure will build southeast
through the central Great Lakes tonight through Sunday. Another
low pressure system will move northeast through the Ohio Valley
late Monday and Monday night and off the New England coast
Tuesday. A ridge of high pressure will build northeast into the
eastern Great Lakes through mid week followed by an Alberta
Clipper Thursday.

&&

.NEAR TERM /THROUGH SUNDAY/...
Rain is beginning to transition to rain/snow and to an all snow
in some areas. The transition to all snow is occurring earlier
than expected, which is due to cooler temperatures than
expected in some areas. The timing of the transition to all snow
will be heavily dependent on hourly surface temperatures today,
which will be a significant challenge given the variance across
the area and small changes having a big impact on the forecast.
Model guidance is too warm in areas like Mansfield, Marion,
Wooster, inland areas of Cuyahoga, Summit Medina, and Geauga
Counties, but are too cold in northwest Ohio and lakeshore
communities. This makes it a challenge because no one model is
performing best, and thus makes it difficult to generate
precipitation type and snowfall forecast. Have increased
snowfall amounts a little bit but if cooling trend continues,
will have to increase snowfall amounts even further. Currently
have widespread accumulations of around half an inch with up to
2 inches in Geauga and Ashtabula Counties in Ohio. In Northwest
Pennsylvania, have up to 7 inches in eastern parts of inland
Erie County and 2 to 4 inches in Crawford County.

Original Discussion...
An upper level trough of low pressure
will move east across the Great Lakes and become negatively
tilted by later this morning. The transition of the upper level
trough will cause low pressure over southern West Virginia to
rapidly intensify later this afternoon. The low will initially
bring abundant moisture to the local area and then as the flow
shifts around to the north, colder air will be forced south and
this should change the precipitation over to all snow from west
to east. Snow could be mixed with the rain over the western half
of the forecast area through the morning hours. This will be a
difficult forecast for northwest Pennsylvania because the
changeover timing is highly dependent on how fast the cold air
descends through the column. Model soundings indicate gradual
cooling aloft and the surface being the last to go below
freezing. Expecting heaviest snow to occur in northwest
Pennsylvania to occur this afternoon and evening and then
transition to lake effect that will affect northeast Ohio as
well. Inversion height will rise to around 7000 feet tonight and
enough synoptic moisture lingers to support snow. There is the
possibility that we could see higher snow accumulations
overnight depending on how organized the lake effect becomes.
Snow threat diminishes Sunday afternoon and evening as inversion
settles down and drier air works into the region. Therefore,
will go ahead and hoist a winter weather advisory for inland
Erie county in Pennsylvania. Snow accumulations of 4 to 6 inches
can be expected in the advisory area. Lesser accumulations
expected along the lakeshore and south of Erie county.

For the rest of the forecast area, expecting the rain/snow mix
in the west at Toledo/Findlay and mainly rain elsewhere. Then as
low pulls out to the east, the threat for precipitation outside
of the snowbelt areas diminishes.

Temperatures will likely max out by mid day across the area
ahead of the cold air advection and will see colder temperatures
tonight. Cold air advection will continue through tomorrow with
highs in the lower 30s.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/...
Snow showers will be ending or diminishing to flurries fairly
quickly Sunday evening. The flow will be backing with a brief stay
of high pressure Sunday evening. The next system originating from
the Texas panhandle will develop and move to the lower Ohio Valley
for Monday night/Tuesday. With cold air initially in place and warm
air advancing aloft, this system is likely to yield a wintry mix,
especially across the southern/southeastern counties. Have freezing
rain chances mentioned, but the track of the low will be critical
and will need to closely monitor. This system may yield a Winter
Weather Advisory for the area Monday into Monday night. Did limit
PoPs some Sunday night/early Monday with an initial weak wave and a
more southern track. Colder air filters in behind this system with a
changeover to all snow Monday night.  Snow departs Tuesday with dry
air and backing flow. Lake effect to take over though late Tuesday
night with another surge of colder air and deeper moisture. After
temperatures staying within an upper 20 to low/mid 30s range from
Sunday night through Tuesday, Tuesday night's lows are expected to
drop into the teens.

&&

.LONG TERM /WEDNESDAY THROUGH FRIDAY/...
With the surge of colder air for Wednesday/Thursday and a continued
west-northwest flow, lake effect snow will be a possibility. Will
need to refine precip chances for the snowbelt with coming days.
There is a lot of variation in the amount of moisture that will be
available. Toward Friday, the upper ridge begins to build/shift
overhead. Therefore for Wed/Thu will have highs in the upper
20s/lower 30s respectively, moderating to the mid/upper 30s for
Friday.

&&

.AVIATION /12Z Saturday THROUGH Wednesday/...
A mix of VFR to LIFR expected across the local area as low
pressure moves northeast along the Appalachian Mountains. This
system will continue to bring rain that will become mixed with
and change over to snow as colder air moves into the area behind
the low. The problem with this forecast is that temperatures are
still tricky in timing the changeover to snow. Plan on best
chance of snow over the eastern portions of the forecast area
this afternoon into tonight. Patchy dense fog is affecting the
portions of the area at this time and will remain through the
morning hours. Improving visibilities will take place in the
fog department after sunrise. Some improvement of conditions
will take place later tonight as low pressure pulls out to the
northeast. There is the possibility for some lake effect snow
developing tonight at Erie.

.OUTLOOK...Non-VFR possible Monday and Tuesday with periods of
rain and/or snow.

&&

.MARINE...
Have made timing and areal adjustments to the upcoming Small Craft
Advisory with the latest wind and wave guidance. Deepening low
pressure moving from the mid-Atlantic to New England today will
increase winds on the lake and bring them around from the north to
the west-northwest. West winds will continue from tonight into
Sunday with a peak a solid 30 knots. Not anticipating any Gale
concerns though with the low center quite removed from the local
area. Wind/waves diminish/subside later Sunday. Winds will back with
a brief stay of high pressure Sunday night, but respond to low
pressure moving from the mid-Mississippi Valley to West Virginia
between Monday and Tuesday. Northeast to northwest winds will make
for a choppy lake early Tuesday. Will likely need a Small Craft
Advisory by Tuesday evening through Wednesday with a stronger west-
northwest flow between an advancing cold front cross the Great
Lakes and a building high across the Ohio Valley.
