The Topeka radar (KTWX), 59 km from the middle of the area, began a volume at 23:03 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.

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 Topeka, KS wrote its last area forecast discussion before this severe thunderstorm warning went out at Apr 14, 3:45 PM CDT, 2 hours 18 minutes earlier.

Area forecast discussion, Apr 14, 3:45 PM CDT, 2 hours 18 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TOPEKA KS
345 PM CDT THU APR 14 2011

...MESOSCALE CONVECTIVE DISCUSSION...
2020Z VISIBLE SATELLITE IS NOW SHOWING CU FIELD ALONG THE
DRYLINE IN SOUTH CENTRAL KS BEGINNING TO BECOME MORE AGITATED
WITH UPDRAFTS FORMING. MOST MODEL GUIDANCE INCLUDING THE
EXPERIMENTAL HRRR SHOWS THE DRYLINE BECOMING MORE ACTIVE OVER THE
NEXT HOUR. CLOSER TO OUR AREA...THE RUC AND NAM SHOW THE STRONGEST
INSTABILITY DEVELOPING ALONG A NARROW AXIS JUST AHEAD OF THE
ADVANCING DRYLINE/COLD FRONT NEAR NEWTON KS TO NEAR SALINA KS. ALL
THE LATEST OBJECTIVE GUIDANCE SUGGESTS THE CAP IN THIS AREA IS ALL
BUT GONE AND STORM INITIATION SHOULD OCCUR FROM CENTRAL KS SOUTH
ALONG THE DRYLINE WITHIN THE NEXT HOUR OR SO. THERE IS A REAL
TORNADO CONCERN FOR STORMS THAT DEVELOP ALONG THE OCCLUDED
BOUNDARY NORTH OF THE SURFACE LOW WHERE THE NAM IS PROGGING 0-3KM
CAPE BETWEEN 100 AND 200 J/KM AND 0-1KM HELICITY AROUND 200. WITH
THE UPPER LOW CLOSING OFF OVER CENTRAL KS...THERE COULD BE SOME
LOW TOPPED SUPERCELLS WITH BRIEF TORNADOS ACROSS NORTH CENTRAL KS.
FURTHER SOUTH ALONG THE DRYLINE...MORE CONVENTIONAL SUPERCELLS
WITH A TORNADO THREAT ARE ANTICIPATED. AREAS FROM ABILENE TO
GARNETT WHERE THE INSTABILITY WILL BE GREATEST. FURTHER TO THE
NORTH OF THIS INSTABILITY AXIS...THERE WILL ALSO BE A CHANCE FOR
TORNADOS DUE TO THE BACKED SURFACE WINDS AND STRONG LOW LEVEL
SHEAR EXPECTED TO MOVE ACROSS THE AREA. HOWEVER THE QUALITY OF
MOISTURE AND RESULTING INSTABILITY SUGGESTS IT SHOULD BE MUCH MORE
DIFFICULT FOR TORNADOS TO DEVELOP ACROSS NORTHEAST KS. THE LARGE
DEWPOINT DEPRETIONS ACROSS NORTHEAST KS SUGGESTS STORMS WOULD BE
HIGHER BASED. PERHAPS THE MOST LIKELY SCENARIO WOULD BE FOR A
TORNADIC SUPERCELL TO COME OFF THE DRY LINE AND MOVE
NORTH...WHICH BUNKERS SHOWS A NORTH MOVEMENT AT ABOUT 30KTS FOR A
RIGHT MOVING STORM. NEVERTHELESS THERE WILL REMAIN A LARGE HAIL
AND DAMAGING WIND THREAT NORTH OF THE INSTABILITY AXIS. SEVERE
WEATHER IS EXPECTED TO BE ON THE DECLINE BETWEEN 10 PM AND
MIDNIGHT AS THE FRONT PUSHES EAST AND REMAINING STORMS
INCREASINGLY BECOME MORE ELEVATED WITHIN THE COOL SECTOR ON THE
NORTHER SIDE OF THE STORM SYSTEM.

WOLTERS

&&

.SHORT TERM (TODAY THROUGH TOMORROW MORNING)...POTENT STORM
SYSTEM WILL IMPACT THE AREA THURSDAY AFTERNOON AND EVENING WITH AN
UNSETTLED WEATHER PATTERN EXPECTED THROUGH WEDNESDAY.

CURRENT SURFACE ANALYSIS SHOWS AN IMPRESSIVE 999MB CLOSED LOW
CENTERED OVER SOUTH CENTRAL KANSAS WHILE WATER VAPOR IMAGERY
SHOWS AN AMPLIFIED UPPER LEVEL TROUGH ENTERING WESTERN KANSAS AND
THE OKLAHOMA PANHANDLE. VISIBLE IMAGERY SHOWS AGITATED CUMULUS
DEVELOPING OVER CENTRAL KANSAS WHICH WILL LIKELY BE THE
INITIATING LOCATION FOR STRONG TO SEVERE SHOWERS AND
THUNDERSTORMS TO DEVELOP ALONG AND AHEAD OF THE DRY LINE AND COLD
FRONT. CURRENT MODEL RUNS ARE ON TRACK WITH THIS SYSTEM SHOWING
INITIATION TIME AFTER 2 PM FOR THE FAR WESTERN AND SOUTHWESTERN
COUNTIES OF THE COUNTY WARNING AREA. FOR FURTHER DETAILS ON
TIMING...DURATION AND PARAMETERS IN PLACE...PLEASE REFER TO THE
PREVIOUSLY SENT MESOSCALE DISCUSSION.

WINDS ON THURSDAY WILL BE STEADILY STRONG FROM THE SOUTHEAST AT
15 TO 25 MPH...BACKING TO THE EAST AS THE CLOSED LOW MOVES
FURTHER NORTH AND EAST. AS A RESULT...THE MOISTURE PLUME WILL
CONTINUE NORTHWARD BEHIND THE WARM FRONT WITH DEWPOINTS PEAKING
IN THE MID 50S AS THE WARMER AIR RAISES TEMPERATURES A FEW
DEGREES WARMER IN THE UPPER 70S AND LOWER 80S. AS THE SYSTEM
MOVES THROUGH....EXPECT LIGHT TO MODERATE RAINFALL TO CONTINUE
THROUGH THE EVENING HOURS. ON THE BACKSIDE OF THE
LOW...WIDESPREAD SHOWERS WITH EMBEDDED THUNDER ARE POSSIBLE WITH
THE CHANCES FOR SEVERE WEATHER DECREASING THROUGH THE NIGHT TIME
PERIOD FROM WEST TO EAST. LOW TEMPS WILL QUICKLY FALL TO THE
UPPER 40S AND LOWER 50S. COLD FRONTAL PASSAGE WILL PROGRESS
THROUGH ON FRIDAY MORNING SWITCHING WINDS TO THE NORTH AND
NORTHEAST THROUGHOUT MUCH OF THE DAY.

BOWEN

&&

.LONG TERM (FRIDAY THROUGH THURSDAY)...STRONG ISENTROPIC UPGLIDE
ON THE BACKSIDE OF THE UPPER LOW WILL KEEP PRECIPITATION CHANCES
THROUGHOUT THE DAY ON FRIDAY. TEMPERATURES ON FRIDAY WILL BE MUCH
COOLER WITH STRONG COLD AIR ADVECTION BEHIND THE UPPER LEVEL LOW.
THIS COLD AIR ADVECTION WILL USHER IN TEMPERATURES NEAR FREEZING
ON SATURDAY MORNING ESPECIALLY OVER NORTHWESTERN PORTIONS OF THE
CWA. HOWEVER...ISENTROPIC UPGLIDE WILL KEEP CLOUD COVER IN THE
AREA UNTIL EARLY SATURDAY MORNING AND MIXING BEHIND THE UPPER LOW
WILL KEEP WINDS AROUND 15 TO 20 MPH OVERNIGHT. THESE TWO FACTORS
MAY KEEP TEMPS FROM FALLING BELOW FREEZING. ON SATURDAY THE
SURFACE RIDGE WILL MOVE ACROSS NORTHEAST KANSAS. ON SATURDAY SKIES
WILL CLEAR AND TEMPERATURES WILL BE AROUND SEASONAL AVERAGES. AS
THE RIDGE AXIS MOVES THROUGH SOUTHERLY FLOW RETURNS TO THE AREA
SATURDAY NIGHT AND SUNDAY. ON SUNDAY MODELS INDICATE ISENTROPIC
UPGLIDE AS WELL AS LEE CYCLOGENESIS. THIS COMBINATION OF WARM AIR
ADVECTION AND ISENTROPIC UPGLIDE WILL BRING THE CHANCE OF RAIN
INTO THE CWA ON SUNDAY PERSISTING INTO MONDAY.

NEXT WEEK A SERIES OF UPPER LEVEL WAVES WILL MOVE THROUGH THE CWA
KEEPING THE WEATHER FAIRLY ACTIVE. THE GFS INDICATES THE SURFACE
COLD FRONT WILL MOVE THROUGH THE CWA OVERNIGHT MONDAY. ISENTROPIC
ANALYSIS SHOWS STRONG ISENTROPIC UPGLIDE MONDAY NIGHT INTO TUESDAY
FOR OVERRUNNING PRECIPITATION. GFS SHOWS THE SURFACE BOUNDARY
MOVING SLOWLY KEEP OVERRUNNING PRECIPITATION IN THE CWA UNTIL
WEDNESDAY MORNING. SIMILAR SOLUTION IS INDICATED ON THE EUROPEAN
WITH STRONG ISENTROPIC UPGLIDE MONDAY NIGHT INTO TUESDAY. SURFACE
RIDGE QUICKLY MOVES THROUGH ON WEDNESDAY BEFORE ANOTHER UPPER
LEVEL WAVE BRINGS PRECIP CHANCES TO THE AREA ON THURSDAY.

&&

.AVIATION...
A STRONG UPPER LEVEL SYSTEM WILL TRANSLATE ACROSS THE AREA
THURSDAY AFTERNOON/EVENING WITH ISOLATED TSRA EXPECTED AT ALL
TERMINALS. STRONG SOUTHEAST WINDS WILL CONTINUE THROUGH THE
AFTERNOON...BECOMING GUSTY UP TO 30 KTS WITH VRB WIND DIRECTION AS
STRONG TO SEVERE TSRA PASSES OVERHEAD BETWEEN 22Z AND 05Z
RESPECTIVELY. AFTER 05Z RAIN WITH EMBEDDED THUNDER WILL CONTINUE
OVERNIGHT AS CIGS/VIS FALL NEAR 1000 FT AGL. MVFR CONDITIONS AND
REDUCED VIS WILL CONTINUE THROUGH FRIDAY MORNING AS A COLD FRONT
MOVES THROUGH...CALMING AND BACKING WINDS TO THE NORTHEAST AT OR
BELOW 10 KTS.
