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.

NWS Tulsa, OK wrote its last area forecast discussion before this severe thunderstorm warning went out at Mar 27, 6:25 PM CDT, 10 minutes earlier.

Area forecast discussion, Mar 27, 6:25 PM CDT, 10 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
625 PM CDT FRI MAR 27 2009

.DISCUSSION...

.AVIATION...
ONGOING CONVECTION IN ADVANCE OF UPPER LOW CENTER WILL CONTINUE TO
ROTATE ACROSS TAF SITES THIS EVENING...WITH IMPACTS BECOMING
FOCUSED ACROSS NORTHERN LOCATIONS ESPECIALLY KTUL/KRVS LATE
TONIGHT. CEILINGS MAY RAISE BRIEFING ACROSS THE FAR SOUTH EARLY
TOMORROW MORNING...BEFORE PRECIP ON BACK SIDE OF UPPER LOW TRACKS
INTO THE AREA. THIS SECOND ROUND OF PRECIP WILL BE THE TRANSITION
TO THE SNOW POTENTIAL...WITH THE MOST SIGNIFICANT SNOW AND LOWEST
FLIGHT CATEGORIES AGAIN FOCUSED TOWARD KTUL/KRVS SITES. CONDITIONS
SHOULD BEGIN TO IMPROVE BY LATE TOMORROW AFTERNOON HOWEVER STRONG
NORTHWESTERLY WINDS WILL CONTINUE.

&&

.PREV DISCUSSION... /ISSUED 350 PM CDT FRI MAR 27 2009/

DISCUSSION...
VERY DIFFICULT FORECAST WITH VERY POWERFUL LATE WINTER SYSTEM.
MODELS HAVE BECOME SIMILAR IN HANDLING THE SYSTEM AS IT MOVES
THROUGH THE AREA BUT TEMPERATURE PARAMETERS SEEM A LITTLE
OFF FROM OBSERVED VALUES AND DUE TO THE SUBTLE DIFFERENCES
THAT ARE ENOUGH TO MAKE BIG DIFFERENCES IN TYPE AND AMOUNTS
MAKES FOR A CONFUSING FORECAST.

UPPER LOW NEAR THE NEW MEXICO/TEXAS BORDER AND WILL MOVE EASTWARD
ALONG THE RED RIVER BEFORE TUNING TOWARDS THE NORTHEAST ACROSS
SOUTHEAST OKLAHOMA AND INTO ARKANSAS AND THEN SOUTHERN MISSOURI BY
LATE SATURDAY.

CURRENTLY SOME MIXTURE OF SNOW...RAIN...SLEET...AND FREEZING
RAIN HAVE BEEN REPORTED IN WESTERN OSAGE COUNTY WITH RAIN
AND HAIL PRODUCING THUNDERSTORMS BEING REPORTED OVER THE
REMAINDER OF THE REGION.

BELIEVE TEMPERATURES WILL REMAIN ABOVE FREEZING FOR
MOST OF THE FORECAST AREA TONIGHT WITH THE EXCEPTION OF
OSAGE...PAWNEE...AND WASHINGTON COUNTIES. EXPECT A CHANGE
TO MAINLY SNOW IN THOSE THREE COUNTIES WILL WIDELY VARYING
AMOUNTS WITH NEARLY 8 INCHES...OR MORE IF CONVECTIVE
CELLS MOVE OVER THE AREA IN THE WEST WITH ONLY 2 TO 4
INCHES IN THE EASTERN MOST SECTIONS OF THESE COUNTIES.

JUST SOUTHEAST OF THE WINTER STORM WARNING...HAVE DECIDED
TO GO WITH WINTER WEATHER ADVISORY FOR A MIXTURE OF
PRECIPITATION TYPES. RAIN TONIGHT WILL CHANGE TO MIXTURE
OF FREEZING RAIN/SLEET AND SNOW MOST LIKELY DURING THE
3 AM TO 6 AM PERIOD AND THEN DURING SATURDAY MORNING
CHANGE TOWARDS MAINLY SNOW. ACCUMULATIONS IN THE NORTHERN
COUNTIES WILL BE IN THE ONE TO 3 INCH RANGE BUT COULD BE
SIGNIFICANTLY MORE IF THE CHANGE OVER TAKES PLACE BEFORE
THAT TIME FRAME.

IF THAT IS NOT ENOUGH...SHEAR AND INSTABILITY ADDS A
TORNADO THREAT TO FAR SOUTHEAST OKLAHOMA THROUGH
THE EVENING HOURS.

THE FORECAST ALSO INCLUDES A RAPID RETURN TO WARMING
TEMPERATURES ON SUNDAY AND MOST OR ALL OF THE FROZEN
PRECIPITATION IN EASTERN OKLAHOMA IS EXPECTED TO BE
GONE BY MONDAY.

SOME FREEZING RAIN IS EXPECTED IN THE MIXTURE BUT AMOUNTS
SHOULD BE LOW ENOUGH FOR THAT PARAMETER TO ONLY CAUSE
MINOR PROBLEMS.

AFTER SATURDAY...HAVE USED A BLEND OF MODEL DATA FOR
NEXT WEEK WITH A RETURN TO MORE NORMAL LATE MARCH/EARLY
APRIL CONDITIONS.
