Synopsis
Low pressure over northwest missouri will move to the central
great lakes by this evening. This will allow a warm front to
lift northward across the region this morning. A cold front will
sweep eastward across northern ohio and northwestern
pennsylvania this evening into the overnight. High pressure will
briefly build across that area Thursday night into Friday. A
much stronger storm system will move into the central great
lakes over the weekend.

Near term through Thursday
System largely evolving as expected. Area holding on to snow a
bit longer, but with higher level moisture exiting, could see
some light freezing rain freezing drizzle until temperatures
warm enough. Another surge of rain showers moves in later this
afternoon. No significant changes were made. Previous discussion
follows.

Continue to watch the area of snow slowly move northward with
it now moving into NE ohio. Latest snow reports we have seen
are 1 to locally 3 inches across the southern cwa. Highest
amounts likely across morrow and know counties where several 3
inch reports are expected. Seems we will see a surge of warmer
air around mid morning move into the southern portion of the
area. So a brief transition of sleet to freezing rain is
anticipated. Still believe the greatest chance for icing will be
across interior NW pa but all locations could see some ice on
elevated untreated surfaces.

Previous discussion...

warm front is moving toward the region this morning. Seeing
light snow starting to move into the southern county warning
area (cwa). The heaviest swath of snow still looks like it will
be across the southern CWA near and south of us 30. A couple
inches of snow will be possible in this area before it changes
over to freezing rain. Further north it appears that the snow
will be lighter but the potential for freezing rain during the
morning commute remains possible. A light glaze is possible
through the morning hours but then transition to all rain by mid
afternoon. The corners of the cwa, NW oh and NW pa, will see
the freezing rain potential linger the longest. Since there is a
light glaze of ice possible across the area we will leave the
winter weather advisory in its current configuration.

A cold front will sweep across the area this evening into the
overnight hours. The warmest temperatures of the day will occur
just ahead of the cold front this evening. So the highs for the
day, in the 40s, will be after dark for a large portion of the
region. The remaining rain will transition to a few snow showers
late tonight into Thursday morning. High pressure should be
ridging into the region by Thursday afternoon. Some sunshine
will be possible Thursday afternoon which may help to nudge
highs close to 40 degrees.

Short term Thursday night through Saturday
Dry conditions expected Thursday night through Friday as high
pressure builds east across the region. Min temperatures on
Thursday night will be a little tricky based on the degree of
clearing of the low cloud and the influence of cirrus and high
cloud aloft, dropping into the lower to mid 20s most areas.

Expecting temperatures to recover fairly well with filtered sun
on Friday with highs near 40.

Moisture surges back north Friday night into Saturday with deep
southwest flow ahead of a system moving out of the plains. The
northward extent of the precipitation late Friday night is a little
uncertain given the dry low level easterly flow. If precipitation
arrives in areas before temperatures have a chance to warm above
freezing then could see a quick shot of light freezing rain but
chances look low. Best chance would be towards the toledo area but
would be short lived even there as temperatures climb on Saturday.

Scattered showers expected Saturday with winds veering to the south
as a warm front lifts north into the area. Late day highs in the 50s
are expected.

Long term Saturday night through Tuesday
Highly dynamic system lifts out of the plains across the central
great lakes Saturday night through Sunday. A strong low level jet
wrapping north across the area Saturday night will bring showers
with a chance of thunderstorms as the warm sector moves north to
near lake erie. Warming temperatures can be expected Saturday night
with much of the area in the 50s. The system undergoes impressive
deepening both at the surface and aloft as it wraps the cold front
in from the southwest on Sunday morning. Strong winds are expected
with gusts of at least 40-50 mph if the current track holds. Will
need to monitor the track and evolution of this system with the
potential for even stronger wind gusts if the track holds.

Cold advection behind the front will bring falling temperatures
through the day on Sunday with 850mb temperatures falling by nearly
25c in 24 hours. Lingering showers will transition back to snow on
Sunday night before drying out on Monday morning. Temperatures will
back to near normal by Monday.

Aviation 12z Wednesday through Sunday
The area of snow with MVFR ifr conditions continues to move
northeastward across the area. All TAF sites in ohio either are
or will shortly have MVFR ifr conditions. The snow will
transition to a wintry mix through mid morning, lingering
longest across NW oh and NW pa. All locations should transition
to rain through mid afternoon.

Southeast winds will increase through the morning. Most
locations will be around 12 knots but a few gusts may reach 20
knots. Southerly winds this afternoon will shift to the
southwest and west this evening into the overnight. Gusts may
reach 20 to 25 knots with the southwest to west winds.

Outlook... Non-vfr Thursday. NonVFR possible again Saturday Sunday.

Marine
The lake remains mostly ice covered. Easterly flow of 15-20 knots
this morning will veer to the south today as a warm front approaches
from the south. A cold front will quickly follow this evening with
southwest winds increasing to 15-25 knots with locally up to 30
knots on the far east end into Thursday. High pressure will build
east across the region Thursday night through Friday night.

A rapidly deepening low pressure system will track out of the plains
on Saturday, moving northeast across the central great lakes
Saturday night into Sunday and bring strong winds to the region. If
the current track holds, gales are likely on lake erie as the cold
front is wrapped east across the lake. Increased winds accordingly
in the forecast but they may need to be raised even more. Winds will
veer to the northwest on Sunday night and decrease through the day
on Monday.
