Synopsis
A cold front will cross the area this evening. A series of
troughs will cross the eastern great lakes and upper ohio
valley through the weekend and into Monday. High pressure will
then move overhead for the remainder of the work week with one
cold front sagging southward nearing lake erie Thursday into
Friday.

Near term until 6 am Saturday morning
The widespread heavy rain threat has pushed south of the area,
with light to moderate rain remaining across the southern half
of our county warning area to start the evening. But the cold
front remains across far southeast mi northwest oh and with
soupy airmass, localized heavy rain still a threat this evening.

Just enough instability for a few thunderstorms as northwest oh
has been able to warm the best this afternoon. All precip
should be east of the area by about 3am. Cooler tonight with
upper 50s across the west and inland NW pa and lower 60s
elsewhere.

Short term 6 am Saturday morning through Monday night
A broad upper level trough will encompass the great lakes and
ohio valley region for this weekend bringing temperatures down 5
to 10 degrees below normal. A series of surface troughs will
pass, each brining somewhat cooler air to the area each time.

Monday will be the coolest with h8 temperatures around 5c or 6c.

Will have a number of locations which will remain in the 60s
Monday. Lows each night will dip into the 50s. As far as
precipitation goes, one trough crosses Saturday. There likely
will not be enough moisture with it and will keep the mention of
precip out of the forecast. A more pronounced trough crosses
Sunday and we should have a daytime peak in instability showers
as lapse rates steepen. Same GOES for Monday. Will have best
chances each time across northeast oh NW pa.

Long term Tuesday through Friday
Not many changes to the long term today. The period will start out
unseasonably cool with highs Tuesday at least 10 degrees below
normal. There could be some instability showers in the morning in
the east but drier air should win out by afternoon. The high
responsible for the drying will move off to the east on Wednesday.

This will allow another strong storm system to drop over the
northern lakes. This low will pass well to the north on Thursday
with a trailing front pushing south over the area. This will result
in scattered showers and thunderstorm chances beginning Thursday.

The front will stall over the area by Friday resulting in continuing
precip chances. Overall... The models are in fair agreement with
this scenario. Temperatures will be back to near normal by Thursday
and Friday.

Aviation 18z Friday through Wednesday
A band of rain with embedded thunder continues across the area
this afternoon. Do not think the main band will come north from
it's current location which means places like tol will see
little if any additional rain. A cold front just north of the
area will push south across the area by late evening. It will
take the remaining precip with it. A period of MVFR CIGS is
expected behind the frontal passage with skies clearing
overnight and Saturday morning. Till then little change in vsbys
and CIGS is expected with widespread MVFR and pockets of ifr in
the south where the heavier rain falls. MainlyVFR weather is
expected further north.

Outlook... Chance of brief MVFR in showers Sunday into Monday
with a cold front and trough aloft.

Marine
A cold front will sag south across the lake this evening causing the
flow to become west to northwest. This sort of flow regime will
continue most of the weekend. It looks like speeds will increase a
little late tomorrow. Do not think we will need any small craft
headlines but this is something that will need to be watched.

Westerly flow is also expected Monday. Another cold front will
cross the lake by daybreak Tuesday with a return to northwest to
north flow. A ridge will follow Tuesday night with the flow finally
returning to a southerly direction for Wednesday.

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.
