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 May 24, 9:58 PM CDT, 1 hour 49 minutes earlier.
Area forecast discussion, May 24, 9:58 PM CDT, 1 hour 49 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 958 PM CDT FRI MAY 24 2002 RECENT UPPER AIR ANALYSIS INDICATES SHORT WAVE TROUGH OF SIGNIFICANT AMPLITUDE MOVING THROUGH THE CENTRAL PLAINS. NEAR PROXIMITY OF ANOTHER SHORTWAVE TROUGH OVER THE WESTERN GULF/SE TEXAS HAS ENHANCED DEFORMATION/ASCENT OVER THE SOUTHERN HALF OF THE AREA. RESULT EARLIER WAS ABUNDANT SEVERE TSRA THAT HAS EVOLVED RECENTLY INTO A SLIGHTLY ORGANIZED AREA OF LINEAR CONVECTION EXTENDING FROM NEAR TULSA SOUTHWESTWARD TO KNOX CITY IN TEXAS. COLD FRONT MARKS THE WESTERN EDGE OF EXISTING CONVECTION WITH TEMPERATURES IN NORTHWEST OKLAHOMA IN THE UPPER 40S. DESPITE THE COLD TEMPERATURES SURFACE PRESSURES AND PRESSURE RISES BEHIND THE FRONT ARE NOT IMPRESSIVE ENOUGH TO ALLOW THE FRONT TO MOVE RAPIDLY SOUTHWARD OVERNIGHT. WITH ASSISTANCE OF ABOVE MENTIONED UPPER LEVEL FEATURES...BELIEVE CURRENT TSRA WILL MOVE SOUTHEASTWARD OVERNIGHT AFFECTING SOUTH CENTRAL AND SOUTHEAST OKLAHOMA. THE POSSIBILITY OF ADDITIONAL SEVERE TSRA OVERNIGHT WILL REMAIN LOW...AND MAINLY OVER A FEW OF OUR WEST TEXAS COUNTIES JUST SOUTH OF THE FRONT WHERE AIR IS STILL MODERATELY UNSTABLE AND 0-6 KM SHEAR REMAINS NEAR 50 KNOTS. AIRMASS AND VERTICAL WIND SHEAR OVER SOUTHEAST OKLAHOMA APPEAR LESS FAVORABLE FOR SEVERE THUNDERSTORMS OVERNIGHT. JAMES ----------- AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 245 PM CDT FRI MAY 24 2002 VERY BUSY EVENING ON TAP AS ONE SEVERE THUNDERSTORM HAD ALREADY DEVELOPED ACROSS NORTHERN OKLAHOMA AND THIS WILL BE THE BEGINNING OF A TREND THAT WILL CONT THROUGH MUCH OF THE UPCOMING EVENING AND NIGHT. STORMS ARE EXPECTED TO DEVELOP ALONG COLD FRONT...WHICH IS SLOWLY PUSHING SOUTH INTO WESTERN AND NORTHWESTERN OKLAHOMA. INITIALLY...THESE STORMS SHOULD REMAIN MORE SCATTERED/DISCREET IN NATURE ACROSS WRN/SWRN OK AND N TX...WHICH WILL KEEP TORNADO PROB HIGHER THIS EVENING. AS EVENING WEARS ON SHOULD DEVELOP A LARGE COMPLEX OF STORMS WHICH WILL MARCH SLOWLY SOUTH AND EAST ACROSS MUCH OF THE AREA. AS EVENING WEARS ON FOCUS SHIFTS TO MORE STRONG WINDS AND HEAVY RAIN THREATS. ALTHOUGH COULD SEE SOME ISOLATED FLASH FLOODING...WITH ANTECEDENT CONDITIONS WHAT THEY ARE AND THAT SYSTEM SHOULD BE PROGRESSIVE ENOUGH...DO NOT THINK IT WARRANTS FLASH FLOOD WATCH. MUCH OF THIS ACTIVITY SHOULD BE EXITING SE OKLAHOMA SAT MORNING AND MUCH OF THE DAY LOOKS DRY...ESPECIALLY ACROSS NW TWO-THIRDS OF AREA. WOULD LIKE TO BE ABLE TO FORECAST MORE SUNSHINE...BUT MOSTLY CLOUDY LOOKS TO BE THE WAY TO GO THROUGH MUCH OF THIS PACKAGE. WILL ALSO TRY TO REMOVE SOME POPS FOR PORTIONS OF THE AREA THIS WEEKEND...BUT THIS LOOKS TO BE SHORT-LIVED AS MOISTURE IS NOT GOING ANYWHERE THIS TIME AROUND AND MRF ADVERTISES CONT CHANCES THROUGH NEXT WEEK. WILL BUY OFF ON THE MRF DEVELOPING UPPER RIDGE BY LATE IN THE WEEK AND WILL KEEP FRI DRY FOR NOW.
