Synopsis
Low pressure north of the great lakes will move east and drag a
cold front across the local area this evening. High pressure
will take control of the region on Wednesday and persist into
Thursday night.

Near term through Wednesday night
Cold front is now just west of the area and will move east
across the CWA late this afternoon and this evening. Expecting
light rain to move in from the west with and behind the front
with an eventual change to snow before ending outside of any
lake effect region. Not expecting much accum as most of the
precip should occur as rain or a mix. For the snow belt, bufkit
shows a fairly low inversion with this system and no good
sustained period of time when dendrites are favored so not
expecting much lake effect snow as well although given the cold
air over the lake would expect some post front enhancement. Will
have chance pops west and south and likely to categorical across
the snowbelt. Cold air moves in quickly as does the dry air so
am expecting most of the precip to be done by morning. Will
carry a chance pop in the morning and taper to a slight chance
for the afternoon. Will likely hold onto clouds much of the day
through however outside of the lake influence should be more
sun. Will continue dry and partly cloudy for Wednesday night as
high pressure weakens slightly over the region.

Short term Thursday through Saturday the passage of an
upper trough early Thursday will have enough moisture with it to
bring a decent amount of mid and high clouds across the area.

If it can generate precip it may brush the lake and possibly
northwest pa, but it looks unlikely. So, thanksgiving will
largely be benign with southwest winds and temperatures reaching
into the upper 30s lower 40s. High pressure builds across the
ohio valley for Friday clearing the clouds during the day time.

The next system is timed for the weekend. A decent push of warm
air on Friday will boost temperatures into the upper 40s a few
50s and it remain dry until evening. Cold frontal timing looks
to be between late Friday night or early Saturday. Precipitation
coverage is still in question and have continued with a similar
forecast focusing the best chances across the lake and into
northeast oh NW pa going into and through Saturday morning.

Precip type through mid afternoon Saturday will be rain.

Temperatures will struggle Saturday with the cold air advection
underway.

Long term Saturday night through Tuesday
High pressure pushing up the ohio valley Sat night into sun
night will cause lake effect snow showers to gradually taper off
from west to east so expect only some lingering flurries in nw
pa by Mon morning. Dry conditions should prevail for a brief
period then another approaching cold front will produce
increasing clouds Tue with a small chc for shra in the west by
the end of the day.

Temps will be below normal thru Mon then moderate closer to normal
by tue.

Aviation 18z Tuesday through Sunday
Cold front to our west will move through during the late
afternoon and early evening. Expect it into the ktol area around
21-22z time frame, kcle and kmfd around 00z and keri 01z-02z.

ExpectVFR ahead of the front with CIGS dropping to MVFR briefly
in its wake. Southeast of the lake however expect enhancement as
the colder air fills in post front which will keep MVFR
conditions through the balance of the night and possibly into
Wednesday morning before lifting as drier air moves in.

Outlook... Non-vfr conditions possible across extreme NE oh nw
pa into Wednesday evening. The next chance for non-vfr
conditions will come Saturday as another cold front moves
through.

Marine
Current small craft advisory will hold as is. Western basin is set
to expire at 10p. That may be cutting it close for the area just
east of the islands to vermilion. Otherwise the rest of the lake
goes until Wednesday afternoon. A cold front is set to cross the
lake this evening bringing the winds around to the northwest. High
pressure builds over the lake Wednesday. A weak front crosses
Thursday night, but with just enough wind, waves may reach 4 feet
across the east half of the nearshore waters. For the weekend a cold
front is expected to cross the lake sometime late Friday night or
Saturday with increasing southwest flow ahead of it and a shift to
west-southwest behind it. Another trough Saturday night will bring
the winds around to the northwest with cold air advection. Small
craft advisories will likely be needed.

Cle watches warnings advisories
Oh... None.

Pa... None.

Marine... Small craft advisory until 3 pm est Wednesday for lez145>149.

Small craft advisory until 10 pm est this evening for

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
