Synopsis
Broad area of low pressure will move through the central great lakes
through Sunday. A cold front will move south across the area late
Sunday ahead of a trough deepening aloft. High pressure will build
southeast out of canada across the great lakes during the first
half of the week.

Near term through today
Convection has mostly diminished except for showers on lake
erie. The warm water has maintained some instability over the
water with sunset. These showers will continue to move to the se
into northeast ohio. Elsewhere... A muggy night with slowly
falling temperatures is expected with varying amounts of high
clouds. Patchy fog may form in low lying areas. Will continue
with a chance to slight chance of showers and thunderstorms and
taper those pops lower through the night.

Scattered showers and thunderstorms expected to re-develop on
Sunday with diurnal heating ahead of a trough dropping down from
the north. Best coverage is expected in NE oh NW pa where the
better moisture and low level convergence will be located during
the afternoon. The storm prediction center does have the area
in a slight risk for severe thunderstorms, mainly during the
late afternoon and early evening. Coverage will likely be less
than today.

Short term tonight through Tuesday night
A trough will be exiting the region off to the east on Monday.

There could still be a few lingering showers around Monday
morning, mainly across far northeast ohio into northwest
pennsylvania. These should move off to the east by the mid-
afternoon hours. High pressure will start to build in by Monday
night and will be the dominate feature through Wednesday with
dry conditions.

Temperatures Monday and Tuesday will be a bit below normal as
northerly winds continue across the area. Look for temperatures to
rebound back to slightly above normal by Wednesday as winds veer
back to a southwesterly direction.

Long term Wednesday through Saturday
Low pressure will move east across the great lakes forcing a
cold front southeast across the area. The front will become
nearly stationary across the area while weak waves of low
pressure move east along the boundary. Limited moisture
associated with the cold front will slide southeast into the
local area with the front Wednesday night into Thursday. A
vigorous upper level positive vorticity maximum will slide
southeast in an upper level trough. This feature will help to
enhance further development of the low pressure system across
the ohio river valley by Friday morning. The bulk of the
moisture should be southeast of the area and only limited threat
for showers expected going into the end of the week and first
part of the weekend. Warm air advection will take place ahead of
the cold front Wednesday night into Thursday. As the surface
low pressure slides east of the area Friday night, some weak
cold air advection will take place Friday night into Saturday.

Aviation 06z Sunday through Thursday
Most of the terminals will fill in with a mix of MVFR ifr cigs
and vsbys for the remainder of the overnight before beginning to
mix and lift out Sunday morning into a healthy cumulus field.

Scattered thunderstorms to develop across the area focused on
peak heating. Cak yng still have the weak front as a source of
lift and then late in the afternoon upper support arrives from
the central great lakes.

Outlook... Non-vfr in early morning fog mist may continue during
the first half of the week.

Marine
Winds will generally be light and variable through tonight on lake
erie. Winds will turn to the northwest Sunday around 10 knots and
increase to around 15 knots Monday out of the north. Winds will then
slowly veer around from the north to the northeast by Tuesday,
remaining around 10 knots or so. Winds will veer back to the
southwest by Wednesday at less than 10 knots.

Cle watches warnings advisories
Oh... None.

Pa... None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
