Synopsis
A ridge of high pressure will build northeast over the eastern
united states and linger through tonight. A cold front will
move south across the area Sunday. High pressure will build east
out of the middle mississippi valley region Tuesday to the ohio
valley by Wednesday with below average temperatures.

Near term through Sunday
The upper level ridge continues to be firm in control over the
lower ohio river valley this morning. Around the fringes of the
upper level ridge, we are seeing couple clusters of convection.

Some of that convection has been strong and producing localized
heavy rainfall. The main question for today is how much of the
debris high cloudiness we will see over northern ohio and how
will that affect the afternoon high temperatures. The other
question is how much convection will develop on the out skirts
of the dome of high pressure and where that will bring some
relief from that hot temperatures. The hi-res models and short
guidance have been struggling to capture these impulses of
convection.

We will continue with the forecast of afternoon high
temperatures in the lower to middle 90s and afternoon heat
indices reaching 100 to 109 degrees. The best potential for
scattered convection or a cluster of convection developing again
this afternoon and evening will be near the lakeshore as well as
far northeastern ohio into northwest pennsylvania. There will
be the threat for isolated damaging wind gusts and locally heavy
rainfall. The upper level ridge finally starts to break down
tonight and a frontal boundary drifts southward from the upper
great lakes region. There will be more cloud cover around on
Sunday as well as a better chance for widespread scattered
showers and storms by midday and the afternoon across the
region. High temperatures will reach the middle to upper 80s on
Sunday. We will also see the threat for a few isolated strong
to severe storms with damaging wind gusts and locally heavy
rainfall on Sunday.

Short term Sunday night through Tuesday night
Sunday night begins with a cold front near a day to yng line with
convection likely occurring along the boundary. Will have likely
pops along and south of a marion to meadville line with chance pops
elsewhere. Monday an upper trough digging in to the upper midwest
will help to develop low pressure that moves along the boundary. The
low will likely shift the front back north a bit so have increased
pops to categorical south and southeast with likely across much of
the remainder of the area. The low will pull east Monday night and
high pressure will begin building in from the west. However with the
upper trough axis still west of the area and deep moisture east will
need to continue chance pops east. Tuesday and Tuesday night mainly
dry although there is an outside chance of a lake effect shower se
of the lake as 850mb temps drop under 10c. Monday and Tuesday highs
in the 70s.

Long term Wednesday through Saturday
High pressure will remain in control across the region through
much of the period. Saturday into Sunday a cold front will
approach from the northwest and will likely be accompanied by
showers and thunderstorms so will need to monitor for timing.

For now will have increasing clouds and pops mainly Saturday
night. High temps upper 70s to near 80 Wednesday. Thursday
through Saturday highs roughly 80 to 85.

Aviation 06z Saturday through Wednesday
MainlyVFR is expected for TAF sites across northern ohio into
northwest pennsylvania. In the very near term, scattered
convection may impact eri and yng from 06z to 08z and have
mentioned a tempo group for this potential. Otherwise
occasional high clouds will filter through today. There may be
additional scattered convection develop near the lakeshore late
this afternoon and evening but exact location and timing is too
uncertain to mention in tafs at this time. Southwest winds 5 to
10 knots will continue with gusts returning late morning through
the afternoon up to 20 knots.

Outlook... Non-vfr possible in showers and thunderstorms Saturday
night through Monday.

Marine
No headlines are expected through the period although north winds
will bring conditions near small craft advisory levels across the
central basin Monday evening as high pressure begins building in
from the west. For today, expect widely scattered thunderstorms on
the lake as a cold front approaches from the northwest. A better
chance comes tonight and Sunday as the front passes across the lake.

Thunderstorm chances continue however through Monday as the front
moves slowly, south of the lake. Tuesday through Wednesday, high
pressure will build in from the west.
