.DISCUSSION...
KEY MESSAGE 1...
The "heat dome" or upper level ridge of high pressure that has
brought so much heat and humidity this past week is almost done
impacting our weather across the region. We will still have some
lingering heat and humidity to contend with today with highs in
the upper 80s to lower 90s. Our heat index values will be around
100 degrees, especially across northern Ohio. We have extended
heat headlines with a Heat Advisory for today into this
evening for all of northern Ohio. High temperatures will be
closer to seasonable warm levels for early July starting Sunday
through early next week in the lower to middle 80s. High
temperatures may creep back up into the middle to upper 80s
later next week. Overnight low temperatures will be slightly
more comfortable next week in the lower to middle 60s away from
the immediate lakeshore.

KEY MESSAGE 2...
The active storm track has shifted southward back into the
lower Great Lakes and Upper Ohio Valley region thanks to the
"heat dome" sliding away from our area. This means that we will
see several days of unsettled and stormy weather this weekend
into early next week. There is a weak mid level disturbance
riding over the top of the ridge into northwest Ohio this
morning with some scattered convection. The expectation is for
this area of general convection to move eastward through the
morning hours and weaken. It will leave out some outflow
boundaries which new convection will develop around this
afternoon and evening. Given the deep layer shear and some
healthy downward CAPE values, there is a marginal risk for a few
strong to severe storms with damaging wind gusts later today.

A weak mid level short wave trough will approach the area from
the west Sunday and Monday. This trough will keep a higher chance
for scattered showers and thunderstorms in the forecast through
Monday. Given the very moist airmass in place with PWATs of 1.5
to 2 inches any thunderstorm that does develop will be capable
of producing locally heavy rainfall. There is a Marginal Risk
(Level 1 of 4) for Excessive rainfall both today and Sunday.

High pressure will build into the Ohio Valley and lower Great
Lakes region Tuesday and Wednesday with lower rain chances. A
broad upper level trough pattern may develop towards the end of
next week over the Great Lakes region with a weak cold front
moving through late Thursday. Some higher POPs will return back
in the forecast by then.

.AVIATION /12Z Saturday THROUGH Wednesday/...
The main aviation concern remains potential for convection.
Overnight convection has largely dissipated, leaving a clean
slate to start the day. There is increasing confidence in
scattered to numerous thunderstorms firing from interior eastern
OH into interior northwestern PA after 19 or 20z this
afternoon, with impacts most likely at CAK and YNG (included
TEMPO groups for TSRA) and possible at MFD (PROB30) before
storms drift east out of the area this evening. More isolated
activity is possible farther west this afternoon and evening,
but confidence is lower so maintained a PROB30 group for TOL and
FDY. Potential for TS impacts to CLE and ERI is non-zero this
afternoon but is below 30%, precluding a TAF mention at this
time. Did include VCSH at CLE to hedge a bit, as it`s possible
any afternoon thunderstorm development isn`t too far south/east
of the field. Additional showers and perhaps some thunder will
try spreading in from the west overnight...for now, have a
rather benign -SHRA mention at TOL, FDY, MFD and CLE late
tonight into early Sunday. Some non-VFR mist may develop late
tonight, but confidence in a period of clearer/calmer conditions
is currently too low to include in TAFs outside of YNG and CAK.

Winds will start south-southwest today, but will shift more
westerly through the afternoon and even gain a northerly
component closer to Lake Erie. Winds will increase to 6-12kt
during the day. Some stronger thunderstorms can produce brief
and sporadic wind gusts over 40kt this afternoon and evening.

Outlook...Weak low pressure and a cold front move across the
region Sunday and Monday, bringing occasional showers and
thunderstorms. Non-VFR ceilings and visibility also possible
Sunday night into Monday.

&&

.MARINE...
West-southwest winds of 5-10kt this morning shift a bit more
west-northwest this afternoon and evening as a weak cold front
crosses the lake. Winds gradually turn east-northeast tonight
into Sunday, and increase to around 15kt Sunday afternoon and
evening as weak low pressure approaches from the west. Winds
then persist out of the northeast early this week as low
pressure slowly tracks through the upper Ohio Valley. High
pressure builds in towards midweek. The current forecast keeps
winds in the 10-15kt range and waves in the 1-3 foot range
Sunday night through Monday night. Some guidance suggests a
period of winds to around 20kt is possible Sunday night into
Monday as low pressure makes its closest pass. If these trends
continue we will need to nudge the wind and wave forecast up,
and may get close to needing Small Craft/Beach Hazards headlines
between the Islands and Willowick for a period of time. Any
thunderstorms over the lake over the next few days can bring
briefly higher winds and waves.
