Synopsis
High pressure centered over the upper ohio valley will move off
the east coast later today. An area of low pressure will slowly
move from the mississippi valley across the great lakes
Wednesday and Thursday. High pressure will briefly build over
the region Friday into Saturday but another frontal system is
expected over the weekend.

Near term /until 6 pm this evening/
Weak high pressure remains in control this morning. Satellite
showing lot's of high clouds over the area so any sunshine
today will be filtered. Southerly flow will return to the entire
area today which will push temperatures a little warmer than
they were on Monday even with the thicker clouds. Given the
weak pressure gradient a lake breeze is likely this afternoon
and locations along the immediate lakeshore could be chilly. As
it stands have again used a blend of guidance temps.

Short term /6 pm this evening through Friday night/
Have continued the recent trend of slowing the onset of precip
down. We should be able to squeak out a dry night and most of
the area will remain dry into Wednesday afternoon. Some question
as to whether NW pa will see any showers before early evening.

The models continue to have some differences handling the track
and movement of the low set to move into the region on
Wednesday. These differences should have little impact on the
practical weather as widespread precip is expected by tomorrow
evening. Forecast soundings show some instablilty and cape
tomorrow morning but once the steadier rain starts things should
stabilize. The previous forecast already had thunder mentioned
for Wednesday so will leave it in the forecast although I have
trimmed it back some. Showery weather will continue Wednesday
night and again Thursday. The low itself should finally move
off to the east Thursday night. Drier air will work into the
western end of the area Thursday night behind the low.

But... Locations downwind of the lake could see some instability
showers into Friday evening.

Temps for the most part will be seasonable. Highs Wednesday will
be warmest in the east since it will take longer for the precip
to arrive. Thursday will be a gray day with temps a tad below
normal but seasonable readings are again expected by Friday.

Have used a blend of guidance temps.

Long term /Saturday through Monday/
Little change to the long term forecast with active pattern bringing
periodic precip chances through the holiday weekend. Model
differences lend to lower confidence during this period, with low
pressure tracking somewhere through the region Saturday night
through Sunday. Then, a series of shortwaves are expected to rotate
through the great lakes Sunday night through Monday as upper low
settles southeast into the northern lakes. Will hold with generally
slight chance/chance pops through much of the period, with likely
pops Sunday as models somewhat agree on decent rain chances that
day. Temperatures will be seasonable to slightly above normal during
this period, with cooler temps possible just after this period
toward the middle of the week.

Aviation /06z Tuesday through Saturday/
Quiet TAF period withVFR conditions expected as high pressure
pushes east of the region. Scattered to broken cirrus will
overspread terminals through the day, with some mid level
ceilings pushing in after 00z. Light gradient will allow for
lake breeze to push into kcle and keri this afternoon with winds
flipping out of the north, otherwise winds will remain light and
predominantly south-southeasterly through the period.

Outlook... Non-vfr likely Wednesday and Thursday in showers and
tsra.

Marine
Quiet conditions expected on lake erie as surface ridge axis slowly
pushes east of the area today. Southerly flow will decrease through
the morning becoming light and variable, then increasing out of the
east 5 to 10 knots this evening. East northeast flow will increase
to 10 to 20 knots Wednesday as low pressure deepens and tracks
northeast towards the lake. The flow will gradually veer southerly
by Thursday morning and westerly by Thursday evening as the low
lifts north of the lake. Flow will remain westerly through Friday in
the 10 to 15 knot range.

Cle watches/warnings/advisories
Oh... None.

Pa... None.

Marine... None.

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.
