Synopsis
A weak cold front will push east across the area tonight. High
pressure will briefly build into the region Tuesday before a
weak trough of low pressure swings through the southern great
lakes Tuesday night into Wednesday. A large area of high
pressure will drift east across the great lakes and ohio valley
Wednesday through Thursday night.

Near term through Tuesday night
Watching two areas of showers with isolated thunder. The first
was across northwest ohio ahead of the cold front. Made the
showers "scattered" versus "chance" for northwest ohio this
evening. The other area of showers was across extreme northeast
oh and northwest pa. These showers should shift east and
diminish by 8 pm or so. Made a few other minor adjustments to
the pop tonight based on the latest meso models to keep a
chance slight chance of showers a little longer across north
central ohio tonight. No other changes for the evening update.

Original "tonight" discussion...

isolated showers beginning to develop mainly east of the i-71
corridor this afternoon. Went ahead and upped pops to mid chance
for a few hours late this afternoon. A few rumbles of thunder
are possible, with around 500 j kg of SBCAPE across the area. A
cold front will push east across the area tonight. Hi- res
guidance continues to indicate widely scattered precip ahead of
the front, spreading east across the area through the night,
with slight chance to low chance pops in general. Some thunder
is possible through the evening but any thunder chances should
diminish overnight as the atmosphere stabilizes. Mainly dry
conditions are expected on Tuesday as high pressure briefly
builds through the area. Another weak trough passage through the
area Tuesday night prompts some slight chance pops across the
area. No major changes to temperatures from previous forecast.

Short term Wednesday through Thursday night
Upper level trough axis should be moving across the region on
Wednesday with scattered showers thunderstorms anticipated. High
pressure then builds into the area Wednesday night with drier
conditions returning. The high will move east of the region by
Thursday night with increasing chances of showers as the next
wave approaches in the NW flow.

Wednesday will see temperatures slightly below seasonal averages
but all locations return to average levels for Thursday.

Long term Friday through Monday
Scattered showers and thunderstorms will remain in the forecast
on Friday as yet another wave moves through the upper level
trough. These storms could be a bit stronger but that is
something to watch over the next few days. Cold front should be
moving into central ohio on Saturday with any
showers thunderstorms moving south of the region by Saturday
afternoon. Models differ on the timing of this system across the
area so changes may occur over the next few shifts. High
pressure should build back into the region Sunday into Monday
with drier conditions anticipated.

Temperatures will run within a few degrees of seasonal averages.

Aviation 18z Monday through Saturday
Cold front just NW of tol will push across the forecast area
tonight. Currently scattered showers with isolated tsra ahead of
the front. The tsra will diminish after sunset. Mfvr conditions
in the heavier rain showers.

Outlook... Non-vfr at times Wednesday into Wednesday night.

Marine
Winds and waves should decrease overnight with waves running in
the 1 to 3 foot range. Southwesterly winds will increase Tuesday
night into Wednesday but we should not have any larger waves on
the south shore of the lake. As a weak trough front crosses the
lake on Wednesday allowing winds to shift more to the west. This
may build waves to near small craft advisory levels Wednesday
into Wednesday evening. Winds decrease for Thursday as high
pressure moves across southern ohio.

Cle watches warnings advisories
Oh... None.

Pa... None.

Marine... None.

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.
