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 Tulsa, OK wrote its last area forecast discussion before this severe thunderstorm warning went out at Feb 27, 11:27 PM CST, 1 minute earlier.

Area forecast discussion, Feb 27, 11:27 PM CST, 1 minute before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
1127 PM CST SUN FEB 27 2011

.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM.
FOR THE 6Z TAFS... A COLD FRONT WITH ASSOCIATED THUNDERSTORMS IS
CURRENTLY MOVING SOUTHEASTWARD THROUGH THE REGION. THE FRONT HAS
ALREADY PASSED OKLAHOMA TAF SITES AND WILL MOVE ACROSS ARKANSAS
TAF SITES OVER THE NEXT COUPLE OF HOURS. BEHIND THE FRONT...
MVFR CEILINGS WILL PERSIST UNTIL ABOUT MID DAY MONDAY.
NORTHERLY WINDS WILL REMAIN GUSTY THROUGH THE DAY MONDAY... BEFORE
EASING AROUND SUNSET.

&&

.PREV DISCUSSION... /ISSUED 922 PM CST SUN FEB 27 2011/

DISCUSSION...
HAVE EXTENDED THE TORNADO WATCH UNTIL 11 PM AND INCLUDED ALL THE
KANSAS BORDER COUNTIES OVER TO THE MISSOURI BORDER. THE WORST OF
THE STORMS THUS FAR HAVE REMAINED JUST NORTH OF OUR FORECAST
AREA BUT MAY STILL SEE SOME INCREASE IN THE STORMS THAT HAVE
BACKBUILT INTO NORTHEAST OKLAHOMA. THUS FELT IT PRUDENT TO EXTEND
THE WATCH A COUPLE HOURS.

HAVE ALSO SEEN CONVECTION FIRE DURING THE PAST HOUR ALONG THE
DRYLINE THAT HAS BEGUN AN EASTERN PUSH TOWARDS SOUTHEAST OKLAHOMA.
THESE STORMS HAVE REMAINED TAME THUS FAR BUT MAY INCREASE IN
INTENSITY AT ANY TIME AND IF THEY DO...A NEW WATCH WILL LIKELY BE
NEEDED PER COORDINATION WITH THE STORM PREDICTION CENTER.

THERE REMAINS CONSIDERABLE UNCERTAINTY AS TO WHETHER CONVECTION
WILL EVER FILL IN BETWEEN THESE TWO AREAS. THE HRRR KEEPS THE TWO
AREAS SEPARATE BUT DOES SHOW A BIT OF AN INCREASE IN CONVECTIVE
COVERAGE IN NORTHWEST ARKANSAS BY AROUND MIDNIGHT. THE DRYLINE AND
COLD FRONT WILL CONTINUE TO ACCELERATE QUICKLY ACROSS THE AREA AND
ANY SEVERE WEATHER THREAT SHOULD COME TO AN END IN OUR FORECAST
AREA BY 1-2 AM.

HAVE MADE SOME ADJUSTMENTS TO POPS TONIGHT TO FIT CURRENT TRENDS
AND HAVE ALSO LOWERED MINIMUMS A FEW DEGREES BASED ON UPSTREAM
READINGS AND SUPPORT FROM THE NEW 00Z NAM.

UPDATE ON THE WAY.
