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 Feb 24, 7:55 PM CST, 3 hours 5 minutes earlier.

Area forecast discussion, Feb 24, 7:55 PM CST, 3 hours 5 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
755 PM CST THU FEB 24 2000

NOT MUCH TIME FOR DISC THIS EVENING WITH SVR WX ERUPTING NEAR THE
WRN BORDER COUNTIES.  ALREADY UPDATED ZONES A CUPLE HRS AGO TO
REMOVE /TOWARD MORNING/ WORDING FOR ERN ZONES.  WEAK IMPULSE BEING
RAPIDLY EJECTED NEWD IN ADVANCE OF MAIN UPR TROF WILL CONTINUE TO
PRODUCE SCATTERED TSRA ACROSS MUCH OF SOUTHERN OK THRU THE EVENING.

THE BIG SHOW IS NOW JUST TAKING SHAPE ALONG THE DRYLINE FROM JUST
EAST OF LBB TO FAR NERN TX PANHANDLE.  LATEST IMAGES FROM KFDR RADAR
INDICATE SOME DEVELOPMENT NOW OCCURRING EAST OF THE MAIN SQUALL
LINE..SUGGESTING THAT THE POTENTIAL FOR ISOLATED TORNADIC SUPERCELLS
MAY BE INCREASING ACROSS WRN OK.  HOWEVER..THERE WILL CONTINUE TO BE
THE POTENTIAL FOR SUPERCELLS EMBEDDED WITHIN THE SQUALL LINE AS IT
MOVES EWD FOR A GOOD PART OF THE NITE /AS EVIDENCED BY LATEST KLBB
RADAR IMAGES/. CURRENT TIMING LOOKS GOOD AS PACIFIC FRONT CATCHES
THE DRYLINE LATER THIS EVENING AND WILL SURGE EWD OVERNITE.

GOING FORECAST REFLECTS MOST OF THIS THINKING. PERIODIC UPDATES WILL
BE ISSUED AS NECESSARY TO ACCOUNT FOR EVOLVING SITUATION OVERNIGHT.
