The radar

The Indianapolis radar (KIND), 93 km from the middle of the area, began a volume at 23:17 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Cncnati-Daytn, OH (KILN), launched 12:00Z, 11.2 hours before the alert went out and 198 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area forecast discussion, Jun 13, 4:50 PM EDT, 2 hours 23 minutes before

Area Forecast Discussion
National Weather Service Indianapolis IN
450 PM EDT Wed Jun 13 2018

.UPDATE...
The AVIATION Section has been updated below.

&&

.SYNOPSIS...
Issued at 357 PM EDT Wed Jun 13 2018

A frontal system will move out of the area at the beginning of the period
and a high pressure system will move in behind it. The high pressure
will bring dry and hot conditions for the weekend. Chance of
storms are possible again early next week as the ridge weakens.

&&

.NEAR TERM /Rest of Today and Tonight/...

Issued at 357 PM EDT Wed Jun 13 2018

The frontal system tracking towards the SE brings with it a line
of rain showers, isolated lightning, and gusty winds, as well as
slightly cooler temperatures in its wake. It is expected to move
out of central Indiana by this evening. Tonight, temperatures are
expected to dip down near 60.

&&

.SHORT TERM /Thursday through Friday night/...

Issued at 357 PM EDT Wed Jun 13 2018

The high pressure ridge over the area will influence above normal
high temps and mostly dry conditions heading towards the weekend.
Overnight temps are expected to be in the mid to upper 60s. There
is a slight chance of PoPs on Friday near the Illinois boarder
but confidence is still low at this point on whether it will
reach far enough east to affect our region.

&&

.LONG TERM /Saturday through Wednesday/...

Issued at 214 PM EDT Wed Jun 13 2018

The main focus early in this period will be how warm it is going
to be this weekend.

Mid/upper level ridge over the central Plains/MO Valley region
will spread into Indiana and the Lower Ohio Valley which will
bring dry weather and very warm temperatures. Given the rainfall
many areas received within the last week, have kept with the low
90s rather than venture any higher compared to the Memorial Day
weekend when we were relatively dry and made mid 90s. Mid to high
confidence for dry, hot weather this weekend.

It will be around Sunday/Monday time frame that a shortwave trough
will track from an upper low over the Intermountain region
through the northern Plains and Upper Great Lakes that will
flatten out the ridge and introduce the threat rain/thunderstorms
into the forecast late in the forecast period. Will carry a low
confidence late in the period at this time.

&&

.AVIATION /Discussion for the 13/21Z TAF Update/...

Issued at 448 PM EDT Wed Jun 13 2018

Update...
Shifted winds from northwest to west/northwest. No flight category
changes.

Previous Discussion...
Latest satellite and radar imagery shows line of -TSRA along an
advancing cold front between KLAF and KHUF/KIND. This line of
activity will be moving through central Indiana during the next
few hours (by 21Z - 23Z). Looks like there could be some brief
MVFR/IFR near the -TSRA, but would expect VFR conditions
otherwise, and most likely after the passage of the frontal
boundary. VFR expected into tonight and Thursday as high pressure
moves into the area.
