The radar

The Wichita radar (KICT), 9 km from the middle of the area, began a volume at 10:06 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

Lamont, OK (KLMN), launched 00:00Z, 10.1 hours before the alert went out and 124 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.

Skew-T log-p

Temperature in red, dew point in green, the mixed-layer parcel dashed.

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 12, 4:05 AM CDT, 1 hour 1 minute earlier.

Area forecast discussion, Jun 12, 4:05 AM CDT, 1 hour 1 minute before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
405 AM CDT WED JUN 12 2002

THE MAIN CONCERN WITH THIS FORECAST WILL BE THE TIMING AND LOCATION
FOR CONVECTION THROUGH THURSDAY MORNING.

THE FIRST BATCH OF CONVECTION HAS PUSHED DOWN INTO SOUTHERN KANSAS.
THIS TEMPORARILY SWITCHED THE WINDS TO A NORTHERLY DIRECTION WITH
THE THUNDERSTORM OUTFLOW.  HOWEVER...WINDS HAVE QUICKLY TURNED BACK
TO THE SOUTH OVER MUCH OF OUR CWA.  THE LOW LEVEL JET HAS CAUSED
THUNDERSTORMS TO REDEVELOP ACROSS WESTERN OKLAHOMA.  THIS ACTIVITY
MAY EVOLVE INTO A COMPLEX AND TRACK ACROSS PORTIONS OF OUR CWA EARLY
THIS MORNING.  FURTHER THUNDERSTORM DEVELOPMENT MAY TAKE PLACE JUST
ABOUT ANYWHERE THIS AFTERNOON.  LOCATION OF THIS WILL DEPEND ON
WHERE THE MANY DIFFERENT OUTFLOW BOUNDARIES SETUP.  THEREFORE...WILL
JUST BROADBRUSH THE AREA WITH LIKELY POPS.  WILL ALSO EXTEND THE
FLOOD WATCH FOR THE SAME AREAS THROUGH THIS AFTERNOON.

BESIDES ANY CONVECTION THAT FORMS ON REMNANT OUTFLOW BOUNDARIES IN
OUR AREA.  A COMPLEX OF THUNDERSTORMS WILL DEVELOP AS UPSLOPE FLOW
WILL INDUCE MORE CONVECTION IN SOUTHEAST COLORADO AND SOUTHWEST
KANSAS.  THIS WILL DEVELOP INTO AN MCS WHICH WILL TRACK
SOUTHEASTWARD.  IT IS TOO HARD TO TELL WHETHER OR NOT THIS COMPLEX
WILL MOVE INTO OKLAHOMA AND MISS MUCH OF OUR CWA...OR BRING
STRONG DAMAGING WINDS...AND MORE FLOODING ESPECIALLY ALONG THE
OKLAHOMA BORDER.  WITH SUCH UNCERTAINTY WILL CONTINUE CURRENT
FORECAST WITH LOW CHANCE POPS NORTH...AND HIGH CHANCE POPS SOUTH.
HOPEFULLY...MODELS WILL COME INTO BETTER AGREEMENT SO THE NEXT SHIFT
WILL BE ABLE TO PINPOINT THE TRACK OF THE NEXT MCS.

EITHER WAY...THE PRECIPITATION SHOULD COME TO AN END SOMETIME
THURSDAY MORNING.  TEMPERATURES WILL ALSO BE NOTICEABLY COOLER.

SATURDAY THROUGH MONDAY LOOKS LIKE ANOTHER ACTIVE WEATHER PATTERN
FOR KANSAS.  NORTHWEST FLOW ALOFT WILL SEND DOWN THUNDERSTORM
COMPLEXES ESPECIALLY AT NIGHT.  THIS SHOULD HELP TO KEEP
TEMPERATURES SLIGHTLY BELOW NORMAL.  WILL GO CHANCE POPS THROUGH THE
PERIOD.
