Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado 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 tornado warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Norman, OK wrote its last area forecast discussion before this tornado warning went out at Mar 10, 9:23 PM CST, 1 hour 5 minutes earlier.

Area forecast discussion, Mar 10, 9:23 PM CST, 1 hour 5 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
923 PM CST FRI MAR 10 2006

.UPDATE...EVENING SOUNDING FROM FORT WORTH SHOWED MOISTURE HAD
DEEPENED UP CONSIDERABLY SINCE MORNING. THE MOISTURE WEDGED INTO
SOUTHERN OKLAHOMA AHEAD OF THE DRYLINE...AND NEAR A WEAK WARM
FRONT. WATER VAPOR SATELLITE SHOWED A SHORTWAVE TROUGH MOVING FROM
WEST TEXAS INTO FAR SOUTHWEST OKLAHOMA. STRONG LIFT AHEAD OF THIS
FEATURE WAS SUFFICIENT TO INITIATE THE ONGOING SEVERE THUNDERSTORMS
ALONG THE LOW LEVEL MOIST AXIS. REGENERATION OF ACTIVITY HAS BEEN
ANCHORED NEAR MARIETTA...BUT APPEARS TO BE MOVING EAST IN RESPONSE
TO THE SHORTWAVE TROUGH AT UPPER LEVELS. THUNDERSTORMS SHOULD
PROGRESS INTO EASTERN OKLAHOMA NEAR OR JUST AFTER MIDNIGHT.

WOULD NOT BE SURPRISED TO SEE A REPEAT OF THIS EVENT SUNDAY
AFTERNOON...BUT SATURDAY STILL APPEARS DRY...AS THE DRY LINE IS
FORECAST TO MOVE INTO EASTERN OKLAHOMA. MARGINAL RED FLAG FIRE
CONDITIONS FOR TEMPERATURE AND HUMIDITY WILL BE THE MAIN CONCERN
SATURDAY. WILL TAKE A LOOK AT OVERNIGHT TEMPERATURES...AND PERHAPS
STRATUS IN THE AREAS RECEIVING RAIN. OTHERWISE...DO NOT ANTICIPATE
CHANGES EXCEPT TO FOLLOW THE SEVERE WEATHER EAST OUT OF THE
FORECAST AREA. BURKE.

.PREV DISCUSSION... (ISSUED 305 PM CST FRI MAR 10 2006)

DISCUSSION...
LOW LEVEL MOISTURE IS INCREASING ACROSS NORTH CENTRAL TEXAS WITH
UPPER 40S DEWPOINTS REACHING THE METROPLEX AND 60S DEWPOINTS UP TO
COLLEGE STATION AND LUFKIN. THE NORTHERN EDGE OF MOISTURE MAY BE
SHALLOW GIVEN THE LOOKS OF THE CORPUS CHRISTI AND LAKE CHARLES
SOUNDINGS. MOISTURE DEPTH MAY BE IMPROVING ACROSS SOUTHEAST TEXAS
AS MOISTURE HAS NOT MIXED OUT DOWN THERE. SO SOME LOW LEVEL
MOISTURE RETURN INTO SOUTH CENTRAL AND SOUTHEAST OKLAHOMA THIS
EVENING. THUNDERSTORMS ARE NOT OUT OF THE QUESTION IN THE FAR
SOUTHEAST AND AGREE WITH SPC THAT IF THUNDERSTORMS OCCUR... SEVERE
STORMS ARE POSSIBLE. BUT AT THE MOMENT WILL NOT INCLUDE POPS IN
THE FORECAST OVERNIGHT SINCE THERE IS UNCERTAINTY ON THE MOISTURE
DEPTH. 00Z SOUNDINGS MAY SHED SOME MORE LIGHT ON THIS POSSIBILITY.

FIRE WEATHER CONCERNS REMAIN HIGH OVER THE NEXT COUPLE OF DAYS...
ESPECIALLY SUNDAY. WINDS LOOK TO BE A LITTLE STRONGER FOR SATURDAY
THAN PREVIOUSLY FORECAST... BUT STILL MARGINAL OR BELOW RFW
CRITERIA. IT WILL BE WARM AND DRY THOUGH. WILL MAINTAIN THE FIRE
WEATHER WATCH FOR TOMORROW AND LET LATER SHIFTS PIN DOWN AREAS TO
UPGRADE IF NECESSARY. RED FLAG WARNING APPEARS MORE LIKELY ON
SUNDAY... BUT WILL TAKE IT ONE DAY AT A TIME AND NOT ISSUE WATCH
FOR SUNDAY YET. THE SUNDAY POTENTIAL IS HIGHLIGHTED ON OUR WEB
PAGE.

DID NOT CHANGE POP FORECASTS MUCH EXCEPT TO ADD 20S IN THE EXTREME
SOUTHEAST ON SATURDAY AS DRYLINE WILL BE IN THE NEIGHBORHOOD AND
MOISTURE MAY BE DEEPER BY THEN.

THERE ARE VARIED SOLUTIONS ON THE STRENGTH/SPEED OF THE WAVE
MOVING OUT SATURDAY NIGHT AND THE SURFACE RESPONSE. GFS IS A
LITTLE STRONGER/FASTER WITH THE WAVE WHICH INCREASES CYCLOGENESIS
SATURDAY NIGHT AND ALLOW SOUTH WINDS TO RETURN AND INCREASE LOW
LEVEL MOISTURE AGAIN. NAM IS SLOWER WITH THIS WAVE AND KEEPS THE
SURFACE FLOW STRONGLY VEERED OVERNIGHT. THIS WILL HAVE
IMPLICATIONS TO PRECIP POSSIBILITIES SATURDAY NIGHT AND SUNDAY.
RIGHT NOW AM KEEPING SATURDAY NIGHT DRY AND KEEPING THE LOW POPS
IN THE EAST ON SUNDAY AHEAD OF SUNDAY/S DRYLINE... BUT WILL HAVE
TO WATCH TRENDS.

IN THE EXTENDED... MAIN CHANGE WAS TO DELAY MID-WEEK FRONTAL
PASSAGE TO THURSDAY CONSISTENT WITH THE ECMWF. THEREFORE INCREASED
TEMPERATURES ON WEDNESDAY.
