What was reported inside it

Time	Report	Where	Remark
Mar 8, 8:15 AM CST	HAIL 0.5	1 N Elmore City, OK

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

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

Norman, OK (KOUN), launched 12:00Z, 1.9 hours before the alert went out and 70 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.

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 Norman, OK wrote its last area forecast discussion before this severe thunderstorm warning went out at Mar 8, 5:42 AM CST, 2 hours 10 minutes earlier.

Area forecast discussion, Mar 8, 5:42 AM CST, 2 hours 10 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
542 AM CST THU MAR 8 2012

.AVIATION...
LOW CLOUDS...TSRA...AND STRONG N WINDS WILL COVER OK AND N TX IN
THE WAKE OF A STRONG COLD FRONT THAT NOW EXTENDS FROM KADH TO
KSPS. CONDITIONS WILL IMPROVE THIS AFTERNOON...ESPECIALLY IN THE N
AND NW...BUT MAY WELL REMAIN MVFR THROUGH THE ENTIRE PERIOD. RAIN
COVERAGE SHOULD DECREASE THIS AFTERNOON/EVENING...BUT CHANCES OF
RA/TSRA WILL CONTINUE INTO TOMORROW AT ALL STIES. WINDS WILL
DECREASE TO LESS THAN 20 KT LATE THIS AFTERNOON IN THE N...AND
THIS EVENING IN THE S. LITTLE CHANGE IS EXPECTED OVERNIGHT.

&&

.PREV DISCUSSION... /ISSUED 509 AM CST THU MAR 8 2012/

DISCUSSION...
WINDS HAVE INCREASED SUBSTANTIALLY OVER THE PAST HOUR OR SO ACROSS
THE SOUTHWEST QUADRANT OF OKLAHOMA. MODEL GUIDANCE SUGGESTS THAT
THESE WINDS MAY CONTINUE WELL INTO THE AFTERNOON...AND EXPAND
SOMEWHAT TO THE SOUTH AND EAST. AS A RESULT...WE HAVE ISSUED A
WIND ADVISORY FOR APPROXIMATELY THE SOUTHWEST HALF OF OUR FORECAST
AREA.

PREV DISCUSSION... /ISSUED 422 AM CST THU MAR 8 2012/

DISCUSSION...
THE COLD FRONT CURRENTLY EXTENDS FROM NEAR SEMINOLE...TO
LAWTON...TO NEAR VERNON...AND ON SOUTHWEST INTO WEST TEXAS. THERE
IS A SHARP TEMPERATURE GRADIENT BEHIND THE FRONT...ALONG WITH
STRONGER WINDS. WE EXPECT WINDS TO NUDGE UP AGAINST WIND ADVISORY
LEVELS OVER WESTERN OKLAHOMA THIS MORNING...BUT SHOULD SUBSIDE
SOMEWHAT TOWARD NOON. WIDESPREAD RAIN...PLUS A FEW
THUNDERSTORMS...WILL CONTINUE ACROSS MOST OF OUR FORECAST AREA
TODAY.

THE UPPER-LEVEL LOW THAT IS ASSOCIATED WITH THIS STORM SYSTEM IS
FORECAST TO CUT OFF FROM THE MAIN FLOW...AND REMAIN OVER THE
SOUTHWESTERN U.S. UNTIL THIS WEEKEND. THIS WILL MAINTAIN A MOIST
FLOW ACROSS THE SOUTHERN PLAINS...KEEPING THE RAIN CHANCES GOING
UNTIL AT LEAST SUNDAY...WHEN THE SYSTEM IS FINALLY FORECAST TO
MOVE OUT TO THE EAST. ANOTHER SYSTEM MAY BRING SOME RAIN NEXT
WEEK...BUT A LACK OF MODEL CONSISTENCY LEAVES NEXT WEEK AS A VERY
LOW CONFIDENCE FORECAST...AND NO SIGNIFICANT RAIN CHANCES ARE
INCLUDED AT THIS POINT.

SOME OF THE PRECIPITATION MAY FALL AS SNOW OR SLEET IN PARTS OF
FAR WESTERN OKLAHOMA TONIGHT AND TOMORROW NIGHT. ALTHOUGH
SOME LIGHT ACCUMULATION IS NOT OUT OF THE QUESTION...IT IS
CURRENTLY TOO UNLIKELY TO MENTION IN THE FORECAST.
