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 Tulsa, OK wrote its last area forecast discussion before this severe thunderstorm warning went out at May 29, 9:45 PM CDT, 1 hour 7 minutes earlier.

Area forecast discussion, May 29, 9:45 PM CDT, 1 hour 7 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
945 PM CDT TUE MAY 29 2012

.DISCUSSION...
STORM EVOLUTION INTO A SOUTHEAST MOVING COMPLEX IS WELL UNDERWAY
WITH A TRANSITION AWAY FROM A HAIL THREAT AND TOWARDS A DAMAGING
WIND THREAT. THE GREATEST INSTABILITY IS ACROSS SOUTH CENTRAL
OKLAHOMA SO THE WORST OF THE STORMS WILL LIKELY REMAIN CONFINED TO
THE SOUTHWEST PART OF OUR FORECAST AREA FROM HERE ON
OUT...ALTHOUGH ISOLATED WIND GUSTS NEAR 60 MILES AN HOUR WILL BE
POSSIBLE JUST ABOUT ANYWHERE ALONG THE LEADING EDGE OF THE LINE.

HAVE ADJUSTED POPS AND SKY COVER OVERNIGHT TO FIT CURRENT AND
EXPECTED TRENDS WITH THE REST OF THE FORECAST LEFT AS IS FOR NOW.
WE WILL LIKELY BEGIN CANCELLING COUNTIES FROM THE SEVERE
THUNDERSTORM WATCH SHORTLY.

UPDATE ON THE WAY.

ACTIVITY...THOUGH A LIMITED TORNADO THREAT IS POSSIBLE ACROSS
NORTHEAST OKLAHOMA DURING THE EVENING HOURS. THESE THUNDERSTORMS
ARE EXPECTED TO FORM INTO A COMPLEX OF THUNDERSTORMS OVERNIGHT
WITH MORE OF A DAMAGING WIND THREAT ACROSS SOUTHEAST OKLAHOMA AND
NORTHWEST ARKANSAS.

TUESDAY NIGHT THUNDERSTORM ACTIVITY LOOKS TO BE MOVING OUT OF THE
REGION WEDNESDAY MORNING. HOWEVER...WITH THE SURFACE BOUNDARY
REMAINING OVER THE REGION...ADDITIONAL THUNDERSTORMS WITH A SEVERE
WEATHER POTENTIAL WILL BE POSSIBLE AGAIN WEDNESDAY AFTERNOON AND
NIGHT. ALL MODES OF SEVERE WEATHER COULD BE POSSIBLE WITH THIS
ACTIVITY AS THUNDERSTORMS MOVE INTO THE REGION WEDNESDAY
AFTERNOON AND FORM INTO A COMPLEX OF THUNDERSTORMS WEDNESDAY
NIGHT.

THUNDERSTORM POTENTIAL CONTINUES INTO THURSDAY AS THE SURFACE
BOUNDARY PUSHES THROUGH THE REGION AS A COLD FRONT. BEHIND THE
FRONT...COOLER AND DRIER AIR LOOKS TO MOVE INTO THE REGION FOR THE
UPCOMING WEEKEND.
