Synopsis
A cold front will move across the forecast
area overnight. High pressure will build over the
region on Thursday and remain through the weekend.

Near term through Thursday night
A cold front will move across the area overnight
through Thursday morning. This is a fairly significant front and
will bring much cooler air to the region over the next several days.

The 12z run of the models show scattered showers and thunderstorms
overnight. Both GFS and NAM show the development of a surface wave
on the front overnight. The GFS is more aggressive with the surface
low and the pcpn with the model is likely high. I will trend toward
the nam. The surface low will likely slow the movement of the front
between 06z-12z. The front will then push south of the forecast area
Thursday afternoon. The surface wave will keep scattered showers and
thunderstorms in the forecast area overnight through Thursday
afternoon particularly over the southern areas. Dry and fair
conditions with cooler air will filter over the region Thursday
evening into Friday.

Short term Friday through Saturday night
The short term begins Friday with models are showing building high
pressure across the great lakes. A frontal boundary will be stalled
across the tennessee valley with moisture lingering into the lower
ohio valley. Aloft, an upper low will be over quebec with a trough
extending southwest across the eastern and central lakes. While the
airmass will be generally dry, the main concern will be how much
instability with be created by the cool air aloft and leftover low
level moisture. For now, will keep Friday dry albeit with a healthy
crop of afternoon cu. Friday night through Sunday, the high will
dominate the region as it passes across ontario into quebec. With
the high to our north however, winds will be from the northeast and
east on lake erie creating a favorable setup for marginally high
water on the west end. The most likely timing with be Saturday into
Saturday night with winds from the east at 15 to 20 knots. Will need
to monitor this situation in future model runs. Friday and Saturday
look for highs in the low to mid 70s. Sunday highs will reach the
upper 70s.

Long term Sunday through Wednesday
Sunday night and Monday, models take the high east across quebec
with southerly return flow setting up across the ohio valley. Models
show moisture returning but differ on timing. Will lean closer to
the slower ECMWF and bring chance pops back to the southwestern
counties Monday morning and then everywhere across northern ohio in
the afternoon. Moisture will continue to pool into the region Monday
night in advance of an approaching cold front. Models differ on
frontal timing with the GFS showing to just to our west Tuesday
afternoon while the ECMWF hold it off for Wednesday. At this point
will not get too fancy and just have a chance of showers and
thunderstorms Tuesday into Wednesday and await better model
resolution. Highs around 80 Monday and in the lower 80s Tuesday and
Wednesday.

Aviation 18z Wednesday through Monday
Still hanging on to some low clouds early this afternoon, but a
decrease in cloud coverage and higher ceilings are the trend
for cle, fdy, tol, and eri. Cloud coverage becomes more
widespread to the southeast at mfd, cak, and yng, as well as
the chance for vicinity showers that have begun to pop up across
the area. Thinking most of this activity will be low-topped and
have a difficult chance at creating thunder. Some areas of
patchy fog may be possible tonight across the southern tier
(yng, cak) which could lead to some MVFR or even ifr conditions,
but have not included due to low confidence. Attention then
turns to tomorrow morning where a complex of showers will make
their way east across northern oh, leading to lowered ceilings
and MVFR conditions at all TAF sites. Westerly winds under 10kts
will turn northwesterly northerly by tomorrow morning across
the area.

Outlook... Intervals of non-vfr possible primarily with
scattered showers on Thursday.

Marine
Winds on lake erie were from the southwest this afternoon from 10 to
15 knots ahead of a approaching cold front in the central lakes.

This cold front will drop across the lake this evening and early
tonight turning winds out of the northwest. While current
expectations are that on balance, waves will remain below 4 feet,
there could be a window where they will be close central and east
thirds this evening and early tonight. Will need to monitor for
possible small craft advisory if conditions look to be sustained.

The front will remain to our south into the weekend as high pressure
moves across across ontario and quebec. Winds at first, Thursday,
will be light from the northeast. The northeast flow will remain
generally 10 knots or less Thursday night through early Friday night.

After midnight however northeast flow will increase to 10 to 15
knots, increasing to 15 knots Saturday afternoon. Again, waves are
not expected to get to 4 feet but it could be close, especially from
the islands to the central basin. Sunday night into Monday expect 15
to 20 knots from the east to southeast Sunday night, turning out of
the south to southeast on Monday as the high reaches eastern
quebec and the maritimes.

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.
