.WHAT HAS CHANGED...
A Heat Advisory has been issued for parts of Northwest Ohio for
Wednesday. Hot and humid conditions continue on Thursday, and
additional advisories may be needed for part of the area.

&&

.KEY MESSAGES...
1) Occasional chances for showers and thunderstorms continue
ahead of a cold front that crosses on Friday. Risks for locally
heavy rain and severe weather exist, but overall confidence in
organized severe weather or heavy rain is currently low.

2) Hot and humid conditions continue ahead of a cold front that
crosses on Friday, with limited overnight relief. Heat index
values will peak in the 90s to around 100 across much of the
area Wednesday and Thursday, with slightly cooler values closer
to the lakeshore in far Northeast OH and Northwest PA.

3) Generally low impact weather is expected this weekend into
early next week, with a few low rain chances in the forecast.

.DISCUSSION...
KEY MESSAGE 1...

A typical setup for this time of year with occasional chances
for convection until a cold front crosses on Friday, but with
plenty of dry windows and rather low confidence in when/where
the most organized rain/storm chances play out.

For this evening and tonight, weak low pressure currently over
northern lower Michigan will continue to drift east into
Ontario. The warm front has cleared the area, though another
surface trough currently extends across western Ohio and will
work east across the area through early Wednesday. Aloft, a very
weak shortwave trough currently moving east out of the upper
Mississippi Valley will move across the region overnight tonight
into early Wednesday. Will monitor the surface trough moving
east across the area along with the modest upper support that
will move through later tonight for increased shower and thunder
potential. There may also be a few isolated pop-up showers and
storms elsewhere this evening given uncapped instability.
Certainly not looking at a steady/widespread rain this evening
or tonight, but given the humid airmass, instability, and
various weak sources for lift suspect a good number of areas
will get a shower/storm at some point. This activity may linger
into the first part of Wednesday across far Northeast OH and
Northwest PA before continuing to exit east.

The main concern tonight with any convection will be locally
heavy rain, given near record high precipitable water values for
early June, weak flow, and skinny instability profiles. However,
the disorganized nature of any convection should be a limiting
factor for heavy rain/flash flooding potential. Strong low-level
instability and turning along the surface trough axis has led to
some rotating storms in eastern Michigan this afternoon...shear
and forcing are a bit weaker with southward extent into Ohio,
meaning the severe weather threat should be rather minimal.

Wednesday should be a largely dry dry with minimal forcing as a
narrow ridge axis builds in. Lingering northwest flow aloft
across Northeast OH and Northwest PA and potential for an
outflow boundary to linger in that vicinity does offer means for
isolated to widely scattered storms to fire Wednesday
afternoon/evening given moderate to strong instability. However,
with the weak forcing activity should be limited and POPs are
generally in the 20-40% range, briefly a bit higher in parts of
Northeast OH and Northwest PA in the evening. Strong and deep
instability profiles coupled with marginal deep-layer shear can
support a severe risk in the form of damaging winds and perhaps
hail if storms do develop across parts of the area, though
again this is of lower confidence.

A number of models suggest potential for an organized MCS to
develop upstream of our area Wednesday evening and turn
southeast into the deeper instability and towards our area
overnight Wednesday night. A modest west-southwest low-level jet
could help maintain convection into our area if it`s able to
organize upstream. Activity would be on a weakening trend if it
is able to enter our area, though given the humid and unstable
airmass that will persist even overnight can not rule out a severe
weather threat in the form of damaging winds if a robust MCS
can develop upstream and move in. The SPC Day 2 outlook does
include a Slight Risk (level 2 of 5) for Toledo for this
potential, with a Marginal Risk (level 1 of 5) elsewhere.

A similar setup on Thursday, with the ridge axis essentially
overhead but potential for activity from Wednesday night to
linger into Thursday across southern/eastern portions of our
area. Outside of that, there should be plenty of dry time on
Thursday. Will again need to monitor for isolated to scattered
convection Thursday afternoon and evening given the hot, humid,
and very unstable airmass, potential lingering outflow
boundaries or a lake breeze, and modest northwest flow aloft
over the eastern portions of the area. While there`s again low
confidence in widespread/organized convection Thursday afternoon
or evening, there`s some severe weather potential with very
impressive instability profiles. Weaker shear and the discussed
lack of forcing are potential negating factors.

The greatest confidence in organized convection is likely late
Thursday night into Friday along and just ahead of a strong cold
front that will cross on Friday. The front is currently favored
to move across our area Friday morning and early afternoon. If
that works out the greatest severe potential would be to our
west Thursday night and then ramp back up to our east Friday
afternoon. Will continue to pin down the timing of the front,
as even a modest slower trend would increase potential for
severe weather in at least our eastern counties on Friday.

The airmass remains very soupy ahead of the front so locally
heavy rain will remain a concern with any convection until it
clears. The thinking is convection should remain disorganized
or sporadic enough to continue limiting the potential for truly
excessive rain amounts or flash flooding, though if any
training or repeated storms occur it would become an issue.

KEY MESSAGE 2...

Dew points will remain in the upper 60s and lower 70s until the
front clears on Friday, with very warm afternoon highs and mild
overnight lows offering little relief. Lows through Thursday
night will struggle to dip below the upper 60s and lower 70s.
Highs on Wednesday will generally reach the upper 80s and lower
90s, though more clouds and some component of flow off the lake
will keep extreme Northeast Ohio and Northwest PA several
degrees cooler. Thursday`s highs should be rather close to
Wednesday`s, perhaps a degree or two warmer in spots assuming
there isn`t more convection than expected on Thursday. Highs
will begin getting knocked back on Friday as the front crosses.

Have issued a Heat Advisory for much of Northwest Ohio for
Wednesday afternoon. Heat index values should top out in the
upper 90s and lower 100s in the advisory counties. We may need
additional advisories on Thursday for portions of the area,
possibly as far east as Cleveland, though will give another day
of model runs to better evaluate any convective or cloud cover
wrinkles to that forecast. More clouds and a bit more marine
influence in far Northeast OH and Northwest PA will keep peak
heat index values in the upper 80s/lower 90s there both days.
Elsewhere, peak heat index values should get well into the 90s
outside of the heat advisory. Given the early season nature of
the heat and lacking overnight relief, those who are without
proper air conditioning, work outside, or are otherwise
sensitive to the heat will want to take precautions.

KEY MESSAGE 3...

Temperatures will still be summer-like but closer to normal this
weekend, with a re-enforcing shot of cooler air expected to
bring below average temperatures early next week behind a Sunday
cold front. Mainly dry weather is favored this weekend into
early next week, but will need to monitor the expected cold
front on Sunday for shower and storm chances.

.AVIATION /18Z Tuesday THROUGH Sunday/...
Mixed-bag of VFR and MVFR across the TAF sites this afternoon,
associated with pockets of lower ceilings. Highest confidence
for non-VFR vsbys over the next several hours is at TOL/FDY/ERI
as there remain two areas of concern for shower and
thunderstorm development. Anticipate vsbys to briefly fall to
IFR with the passing showers and thunderstorms, and have these
reflected as tempos in the latest update. Another wave of energy
will move east through the area later this evening and
overnight, though confidence in direct TAF impacts remains low.
An area of low ceilings may also develop late overnight into
Wednesday morning, particularly along and east of the I-71
corridor. Although MVFR ceilings are reflected in the latest
update, it is possible for ceilings to trend lower towards IFR
in future packages.

Winds are generally out of the south this afternoon, 10 to 15
knots with periodic gusts of 20 to 25 knots. Winds will
gradually shift towards the southwest overnight, then favor a
west to southwest direction by early Wednesday afternoon, around
10 knots.

Outlook...Periods of non-VFR likely in occasional showers and
thunderstorms through Friday. Another period of non-VFR
conditions is possible in showers and thunderstorms Sunday
afternoon.

&&

.MARINE...
Apart from the threat of thunderstorms into Friday, and potentially
again on Sunday, mainly quiet marine conditions are expected across
Lake Erie through the weekend with no headlines anticipated and flow
generally offshore, south to southwest, 10 to 15 knots. Main period
of concern for any stronger thunderstorms appears to be Wednesday
night into Thursday as guidance is hinting at a line of convection
moving west to east across the Lower Great Lakes.
