What forecasters said that day

The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Cleveland, OH wrote its last area forecast discussion before this special weather statement went out at Jul 13, 7:15 PM EDT, 38 minutes earlier.

Area forecast discussion, Jul 13, 7:15 PM EDT, 38 minutes before
Area Forecast Discussion
National Weather Service Cleveland OH
715 PM EDT WED JUL 13 2016

.SYNOPSIS...
High pressure over the central and southern Appalachians will
drift south and weaken. Meanwhile...cold front will move
southeast toward the area Thursday. A trough of low pressure will
move southeast across the area Friday. High pressure will then
build east across the area over the weekend.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
Convection has developed upstream as expected this evening with
some warnings to our west. The best instability over the local
area will occur over the next few hours, as will our best chance
for severe storms. The bulk shear remains under 20kt, and though
this will increase overnight the instability will inversely
decline. A short wave, responsible for the convection over MO
today, will drift over the region tonight. With some elevated
instability there will be enough support for scattered showers and
thunderstorms overnight and into morning. A few storms will have
brief heavy rain (PW>1.6") and the potential for strong gusty
winds (high DCAPE). Looking at a muggy night as dew points linger
in the upper 60s to lower 70s.

Prev Discussion...
Have made minor changes for the overnight forecast and will keep
the trend of increasing pops into the early evening mainly in the
west with an expectation that scattered convection over Illinois
and Indiana will become more numerous as it spreads into Ohio.
This agrees with the reasoning from SPC. The wind shear is rather
weak(less than 30 knots) but there is enough CAPE and DCAPE to
support downburst formation in some of the stronger cells. Humid
conditions will persist with dewpoints in the upper 60s to lower
70s.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY NIGHT/...
a cold front is expected to sag into the region during the
afternoon and make rather slow progress to the southeast. Drying
aloft is also expected to move into the region and this will allow
some instability to form along with scattered convection. The
timing and location is rather uncertain. The NAM appears to be
suffering from rather intense convective feedback again and has
been discounted. In any event...we expect scattered convection
mainly during max diurnal heating time with just a lingering
chance Thursday evening in the eastern counties.

Drier and cool air will filter in later Thursday night and Friday.
A surface trough will cross the area on Friday and then high
pressure will build over the region on Saturday. 850 mb
temperatures will cool to near 12C and produce seasonal
temperatures on Saturday and Saturday night.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
Relatively zonal and quick flow will bring system across the Great
Lakes Sunday night into Monday. Trailing cold front looks to impact
the local area on Monday with scattered showers/thunderstorms.
Beyond Monday the ridge strengthens to our west and by mid week we
may be on the eastern fringes of the the heat again. Will go with
seasonal temps Monday and Tuesday and begin to bring them up for
Wednesday.

&&

.AVIATION /00Z Thursday THROUGH Monday/...
Scattered TSRA across NW OH will gradually diminish this evening
with the loss of daytime heating and moving into a less sheared
environment. Storms moving across Illinois should also slowly
diminish. Expect scattered showers with isolated TSRA into NW OH
toward midnight local...then will move across forecast area
overnight. Will continue to diminish as they move east so doubts
as to how far east actually make it.

More scattered TSRA tomorrow afternoon ahead of cold front that
will move across the forecast area tomorrow. Location will depend
on the timing of the front. For now just went VCTS across the
southern taf sites tomorrow afternoon.

Outlook...Areas of non-VFR possible Thursday in showers and
thunderstorms. Non-VFR possible across ne OH/nw PA Friday.

&&

.MARINE...
A few rounds of showers/thunderstorms possible between this evening
through Friday as system up across the midwest does not cross the
lake until Friday. The south-southwest flow between 10 and 20 knots
will make the waters just offshore choppy. The east end may be
getting close to marginal small craft advisory conditions
Thursday/Thursday night. A better chance may come on Friday as the
winds shift more westerly for areas east of Cleveland. High pressure
builds across the lake for Saturday and Sunday. The next front will
be crossing the Great Lakes on Monday.

&&

.CLE WATCHES/WARNINGS/ADVISORIES...
OH...None.
PA...None.
MARINE...None.
