Synopsis
High pressure centered over the western great lakes will move east
to new england through tonight. Low pressure will develop over the
southern plains and track towards the central great lakes, pulling a
warm front north into the area. A weak cold front will quickly
follow as this system continues northeast into quebec on
Thursday.

Near term through today
Only some minor changes were made to the arrival time of the
precipitation into the southern cwa. Still looks like a brief
mix to rain, unfortunately it will occur during the morning
commute.

Previous discussion...

winter weather advisories have been posted for the entire area
although impacts for most will be limited. Snow overspreads the
area at first. With good lift and snow growth will see quick
accumulations over the first few hours of snowfall. As warm air
arrives aloft the transition to freezing rain will take place.

With the strong advancement of warm air, think the duration of
freezing rain will be limited to about three hours with the
exception being the toledo area and northwest pa which may hold
on a bit longer. Surface temperatures will warm above freezing
and rain will be the precip type. Best snowfall accumulations
still look to be south of us 30. Icing will be a few several
hundredths of an inch just about anywhere.

This is all due to low pressure moving out of the central
plains to the central great lakes tonight and tapping into deep
moisture. Rain continues into the early evening Wednesday and
then drying wraps in behind the system diminishing the threat of
rain ending up with some light rain drizzle Wednesday night.

Temperatures will fall back several degrees this evening and
then hold steady in the mid 20s. Will rise into the 40s and hold
there into Wednesday evening. By Thursday morning temperatures
return to the freezing mark.

Short term tonight through Friday night
The short term begins Thursday in the wake of a cold front, the
parent low north of the region in southern ontario. High
pressure will be building into the central plains from montana.

Kept a very low chance of leftover flurry into the morning hours
with flow off the lake and retreating moisture. Otherwise
expect dry conditions as the low continues northeast and the
high builds in. High pressure will dominate Thursday night and
Friday. Friday night the high moves to new england and low
pressure moves into the southern plains. Warm advection will
develop across the ohio valley and with southerly flow out of
the glfmx, moisture will be increasing through the night. Both
the GFS and ECMWF bring deep moisture move into the ohio valley
by 12z Saturday. Will have chance pops reaching our southern
most counties by Saturday morning. Main concern would be for the
potential for freezing rain as temps aloft rise well above
freezing. For now also expect surface flow to be out of the
south and with that, warming temps towards morning so will keep
precip just rain. If sub freezing temps linger in nwrn oh into
the morning however the tol area could see a brief period of
freezing rain before turning to rain Saturday morning. For
Saturday, moisture continues to move into the area as southerly
flow continues and the low reaches northern mo.

Long term Saturday through Tuesday
Saturday night the mo low deepens rapidly as it moves into the
central great lakes. A warm front will proceed the low through
the region followed quickly by a cold front. Will have
categorical pops for rain through the overnight. Saturday night
will be another night with rising temps especially east ahead of
the cold front. Sunday highs will likely be early with
steady falling afternoon temps in the cold advection behind the
cold front. Best chance for precip will be far northeast oh and
nwrn pa although not expecting a washout as most forcing will be
well north and east of the region. A similar setup for Sunday
night. Will have chance pops far northeast for flow off the
lake. Temps at 850mb will drop to -10c by Monday morning
effectively changing any precip from rain to snow through the
overnight. Monday, high pressure builds in from the west. Could
see a leftover snow shower nern pa but dry for the most part.

High pressure will provide a dry Monday night. Tuesday another
low heading for the central great lakes will bring an increasing
threat for rain in the afternoon.

Aviation 06z Wednesday through Sunday
Vfr conditions are present across the region early this morning.

This will rapidly change from south to north through sunrise as
an area of light snow spreads northward. The snow will
transition to a wintry mix through mid morning, lingering
longest across NW oh and NW pa. MVFR ifr conditions will arrive
with the light snow and then likely remain into the afternoon
with the transition to rain.

Light east winds will shift to southeast and 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
Light east flow overnight will turn east southeast at 15 to 20 knots
Wednesday as high pressure over the lake moves to new england and
low pressure moves from the mid mississippi valley to southern
wisconsin. The low will continue northeast Wednesday night and
reach southern quebec early Thursday turning winds southwest at
similar speeds. Thursday afternoon through Friday high pressure will
dominate over the lake allowing winds to diminish by evening
Thursday. The next significant system to affect the lake will move
through the central plains Saturday becoming quite strong as it
moves through the central lakes Sunday. Flow will increase from the
southeast Saturday night to 10 to 20 knots turning southwest Sunday
as speeds increase to possibly near gales by Sunday afternoon. Winds
speeds will slowly diminish through Sunday night as flow turns
northwest.
