The radar

The Wichita radar (KICT), 59 km from the middle of the area, began a volume at 22:49 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, 10.8 hours before the alert went out and 158 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, Aug 28, 2:53 PM CDT, 2 hours 55 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
253 PM CDT FRI AUG 28 2015

.SYNOPSIS...
ISSUED AT 253 PM CDT FRI AUG 28 2015

WATER VAPOR IMAGERY SHOWS A COMPACT SHORTWAVE TRACKING ACROSS
CENTRAL/NORTHERN IA WITH RIDGING OVER THE DESERT SW/SOUTHERN
ROCKIES. AT THE SURFACE...COLD FRONT EXTENDS FROM FAR EASTERN
NEBRASKA INTO SW KS WITH A BROAD AREA OF HIGH PRESSURE OVER THE
EASTERN SEABOARD.

&&

.SHORT TERM...(THIS EVENING THROUGH MONDAY)
ISSUED AT 253 PM CDT FRI AUG 28 2015

STORMS ARE EXPECTED TO DEVELOP ALONG THE COLD FRONT IN THE NEXT
FEW HOURS FIRST OVER NORTHEAST KS WITH THIS ACTIVITY TRYING TO
WORK SOUTHWEST THIS EVENING. THE DEVELOPMENT OF THIS ACTIVITY
SHOULD BE AIDED BY THE MID LEVEL TROUGH THAT STILL HAS TO PASS
ACROSS THE AREA. HOW MUCH OF THIS ACTIVITY MAKES IT INTO THE
FORECAST AREA IS THE MAIN QUESTION AND FOR NOW HAVE THE HIGHEST
CONFIDENCE FOR THE NORTHEAST AND EASTERN PORTIONS OF THE FORECAST
AREA. WITH AROUND 2,000J/KG OF CAPE AND 25-30KTS OF 0-6KM
SHEAR...ANY STORM THAT DEVELOP WILL HAVE THE POTENTIAL TO BE
STRONG/LOW END SEVERE. BY SAT MORNING THE BULK OF THE PRECIP WILL
BE SE OF THE FORECAST AREA. UPPER RIDGING WILL CONTINUE TO BUILD
OVER THE SOUTHERN ROCKIES/DESERT SW AS SOME UPPER ENERGY DIVES OUT
OF THE UPPER MISSISSIPPI VALLEY AND RETROGRADES SLIGHTLY INTO
EASTERN OK. THIS IMPULSE IS EXPECTED TO REMAIN NEARLY STATIONARY
INTO THE START OF THE WORK WEEK WITH ANY RAINFALL ASSOCIATED WITH
THIS FEATURE STAYING SOUTHEAST OF THE AREA.

A WARMING TREND WILL COMMENCE SUNDAY AND WILL CONTINUE THROUGH THE
START OF THE WORK WEEK. 850MB TEMPS SUPPORT HIGHS IN THE MID 90S
AREA WIDE BY MON WITH SOME UPPER 90S EVEN POSSIBLE OVER CENTRAL
KS.

.LONG TERM...(TUESDAY THROUGH FRIDAY)
ISSUED AT 253 PM CDT FRI AUG 28 2015

THE MAIN THEME THROUGH THESE EXTENDED PERIODS WILL BE FOR
ABOVE NORMAL TEMPS AND DRY CONDITIONS.

BY TUE A SLOW MOVING UPPER TROUGH WILL BE COMING ON SHORE OVER THE
PACIFIC NW WITH SURFACE LEE TROUGHING SLOWLY STRENGTHENING. 850MB
TEMPS WOULD CONTINUE TO SUPPORT ABOVE NORMAL TEMPS WITH HIGHS IN
THE MID TO UPPER 90S. GOOD MODEL AGREEMENT WITH THE UPPER TROUGH
REMAINING ANCHORED OVER THE NW FOR MID/LATE WEEK WHICH WILL
CONTINUE TO PROMOTE A WARMING TREND AND WITH WARMING MID LEVEL
TEMPS...PRECIP CHANCES WILL REMAIN LOW.

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SATURDAY AFTERNOON)
ISSUED AT 1221 PM CDT FRI AUG 28 2015

LIGHT SHOWERS CONTINUE TO DISSIPATE AND DRIFT EAST ACROSS
SOUTHEAST KANSAS WHILE A SLOW MOVING COLD FRONT APPROACHES FROM
THE NORTHWEST. WINDS ARE EXPECTED TO VEER AS A SFC TROUGH AXIS
MOVES SLOWLY TOWARD SOUTH CENTRAL KS. THIS BOUNDARY MAY ACTUALLY
STALL BEFORE ARRIVING AT KICT SO CONFIDENCE IN THE WIND DIRECTION
REMAINS FAIRLY LOW. THE BEST CHANCE FOR AFTERNOON AND EVENING
STORMS IS EXPECTED TO REMAIN ALONG AND EAST OF THE KANSAS TURNPIKE
AS A SLOW MOVING COLD FRONT ARRIVES OVERNIGHT. STORMS MAY IMPACT
THE KCNU TERMINAL THROUGH THE EVENING HOURS BEFORE DISSIPATING AND
MOVING SOUTHEAST OF THE AREA.
