Area Forecast Discussion
National Weather Service Cleveland OH
340 PM EDT Tue Sep 19 2017

A weak upper level trough will slowly dissipate through
Wednesday. High pressure will then build over the area then
dominate the weather the rest of the week.


Showers/thunderstorms have increased across NW Ohio this
afternoon near a 7H trough/low that will only slowly dissipate
into Wednesday. So expect to see isolated to scattered
showers/thunderstorms through the evening across northern Ohio.
However the best coverage will be across NW Ohio this evening.
This weak upper level ripple will drift a bit further east
tonight into Wednesday with isolated/scattered thunderstorms
once again anticipated.

Fog may become an issue where it rained today. Some locally
dense fog is likely across NW Ohio. A dense fog advisory may be
needed later tonight.

Lows tonight and Wednesday night will remain above seasonal
averages with upper 50s to mid 60s common. Highs on Wednesday
should range from the upper 70s to mid 80s.


An upper level ridge will be in place across the region Thursday
through Saturday. Above normal temperatures with dry conditions can
be expected throughout the short term. Winds will be light.


A highly amplified upper level pattern across the CONUS will leave
the eastern CONUS under a strong ridge through the long term period.
This will provide dry conditions and above normal temperatures to
the local area. Highs in the low to mid 80s are expected during the


.AVIATION /18Z Tuesday THROUGH Sunday/...
Showers/thunderstorms have decreased in coverage and intensity
through the morning. Still may see an isolated stronger
thunderstorm but for the most part the western half of the
region will only see some light mid level showers. Still seeing
some IFR ceilings across the west where the rainfall occurred.
These should gradually lift as breaks in the cloud cover

The coverage of the MVFR/IFR stratus and fog later tonight into
Wednesday morning are uncertain but believe some will develop.
Locations that had rainfall will have the best chances of seeing
the non-VFR conditions.

Weak 7H trough/low will remain over the region into Wednesday.
That slightly cooler air aloft will likely keep
isolated/scattered showers and a few thunderstorms around into
Wednesday. Some patchy non-VFR ceilings will be possible in the

Winds will remain light.

OUTLOOK...Non-VFR possible in fog Thursday through Saturday


Scattered light showers will continue across the western half of the
lake this afternoon. Expect another shot at some scattered showers
Wednesday morning and afternoon. Beyond Wednesday, high pressure
will dominate with dry conditions and light winds.
