What forecasters said that day

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

NWS Wilmington, OH wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 3, 4:07 PM EDT, 50 minutes earlier.

Area forecast discussion, Jul 3, 4:07 PM EDT, 50 minutes before

Area Forecast Discussion
National Weather Service Wilmington OH
407 PM EDT Tue Jul 3 2018

.SYNOPSIS...
A ridge of high pressure will allow for very hot and humid conditions
for Wednesday. An approaching cold front will lead to an
increase in showers and thunderstorms Thursday afternoon into
Thursday night. Cooler and drier conditions are expected for the
weekend.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
Showers and thunderstorms have developed across southwestern
portions of the region. Expect coverage to increase through the
early evening hours especially across western and northwestern
portions of the forecast area, generally northwest of Interstate
71, in response to an upper level disturbance and decent
instability. An isolated strong to severe storms will be
possible in addition to pockets of heavy rain. Widespread severe
weather is not expected. Showers and thunderstorms will taper
off tonight.

Temperatures are somewhat variable with some cloud cover around
the region and thunderstorms. The combination of heat and
humidity today has led to another day with heat index values
near 100. Continued with the special weather statement for this
afternoon for heat mention. A warm night is expected overnight
with lows in the lower 70s. Some river valley fog will be
possible overnight.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/...
Expect Wednesday to be the warmest day with less thunderstorms
expected. Some afternoon thunderstorms across the north will
keep temperatures a few degrees cooler. Have heat advisory and
excessive heat warning in effect for Wednesday with heat index
values in excess of 100 expected across the entire region and
locations in the excessive heat warning in excess of 105.

&&

.LONG TERM /THURSDAY THROUGH TUESDAY/...
With the frontal boundary and associated convection sinking south
into the region Thursday into Thursday night, this will begin a
change in airmass. Both GFS and ECMWF coming in slightly quicker and
a little sharper with the frontal boundary passage. However, will
still be enough warm air dominance to yield Heat Index values near
100 to 103 for areas generally along and south of I-71 and into
portions of the Miami Valley. That being said, with consecutive days
of greater than 100 Heat Index per coordination with Hamilton and
Montgomery counties - cities of Cincinnati and Dayton, this will
mean excessive heat warning for these 2 urban counties continuing
through Thursday. With more widespread convection on Thursday
beginning a little earlier in the north, criteria will not be met
for Northern Miami valley and east Central Indiana.

Through the day Thursday, southern area will be dominated by the
increasingly suppressed ridging. Thursday afternoon and evening the
disturbance to the north will increase convection in an increasingly
unstable environment. Thursday afternoon and evening has the
greatest potential for more organized storms, with some severe
storms possible in SB Cape values near/approaching 4000 J/Kg. Not
much upper level support/shear, so main threat will be potential for
damaging winds. With the boundary very slow moving and continued
ample moisture and anomalously high PWATS, also some threat for
nuisance flooding, with even the potential for flash flooding.

With the front continuing to sag southward Thursday night,
thunderstorm potential continues into early Friday morning before
eventually dropping south of the area. Through the day Friday, drier
conditions and clearing skies under northerly flow as high pressure
again takes over. This high will slowly flatten out and drift toward
the east coast into early next week, with southerly flow on the
backside of the high bringing slowly increasing temperatures and
chances for storms especially in the southwest by early next week,
with storm chances again increasing through the entire area by mid
week.

&&

.AVIATION /20Z TUESDAY THROUGH SUNDAY/...
Showers and thunderstorms will continue to develop and be near
the TAF sites today before decreasing in coverage later this
evening. Some fog will be possible during the overnight hours.
Cannot rule out an isolated thunderstorm on Wednesday, however
coverage will be a lot less and therefore decided to leave out
of the TAFs at this time.

OUTLOOK...Thunderstorms possible Thursday into Friday.
