The radar

The Wichita radar (KICT), 53 km from the middle of the area, began a volume at 21:56 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 severe thunderstorm 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

Topeka, KS (KFOE), launched 12:00Z, 9.9 hours before the alert went out and 216 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.

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 Wichita, KS wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 30, 3:35 PM CDT, 1 hour 18 minutes earlier.

Area forecast discussion, Jun 30, 3:35 PM CDT, 1 hour 18 minutes before

Area Forecast Discussion
National Weather Service Wichita KS
335 PM CDT THU JUN 30 2016

.SHORT TERM...(This evening through Sunday night)
Issued at 327 PM CDT Thu Jun 30 2016

Tonight-Friday:
Convective trends will be the big issue. Barely capped, decently
unstable and weakly forced atmosphere will result in isolated to
scattered thunderstorms through sunset across southern half of
forecast area. A few strong-marginally severe storms are possible.
With loss of heating, expect storms to wane quickly at sunset.
Storms will increase late tonight as 850MB flow increases, along
with increasing 850MB-700MB frontogenesis and convergence. Expect
fairly widespread rain spreading across the area towards
daybreak as Western KS storms move/develop eastward. Good chance
that rain/storms will linger well into the afternoon in the east.
Temperatures rather tricky tomorrow with much depending on how
quickly rain/clouds exit.

Friday night-Sunday:
Considerable uncertainty throughout this period, with model
verification of MCS tracks poor over the past week or so, and not
optimistic that today's runs are any better. That said, will
likely be a baroclinic zone somewhere across KS with potential for
multiple rounds of strong storms producing copious rainfall
somewhere in the state. By the weekend precipitable water over 2
inch is forecast by both NAM/GFS. Given uncertainty of timing/
location of heavy rain, will not hoist flood watch at this time
but will mention heavy rain in hazardous weather outlook.
Temperatures also a big unknown, with temperatures likely only in
the 70s in areas where clouds/rain persist throughout the day.
Southern sections may see fair amount of Sunday and hedged
temperatures warmer there. One significant caveat, if storms/
rain shield is large/robust, effective front could push closer to
the OK border, resulting in heavy rain shifting further south
than currently anticipated. Best chance of precipitation appears
late Saturday into Sunday as shortwave moves across the area. -Howerton

.LONG TERM...(Monday through Thursday)
Issued at 327 PM CDT Thu Jun 30 2016

Little changes made to initialization grids. Initial zonal flow
transitions to more ridging by end of period. This will result in
warming temperatures and decreasing chances for precipitation.
-Howerton

&&

.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 1242 PM CDT Thu Jun 30 2016

Cannot rule out a few isolated thunderstorms mid/late this
afternoon and evening over southern KS along a stalling frontal
zone. Suspect activity will be fairly isolated given marginal
convergence and little upper support. Given this fact, left
mention out of Wichita and Chanute TAFs. Better chances for
showers and thunderstorms arrive late tonight and especially
Friday, as the stalled frontal zone sharpens across the region
and shortwave energy begins to approach from the west. Given
uncertainty on timing and location of precipitation, only inserted
VCSH instead of VCTS at all sites for now.
