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 Sep 17, 3:53 PM CDT, 57 minutes earlier.

Area forecast discussion, Sep 17, 3:53 PM CDT, 57 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
353 PM CDT WED SEP 17 2014

.DISCUSSION...
SCATTERED ONGOING CONVECTION ACROSS NW AR IS LIKELY TO SPREAD
SOUTH AND SLIGHTLY WESTWARD THROUGH THE EARLY EVENING AS WEAK
SYNOPTIC LIFT AND AN UNSTABLE AIRMASS INTERACT. A FEW SEVERE
STORMS WILL BE POSSIBLE BEFORE INHIBITION SUFFICIENTLY
STRENGTHENS. A SIMILAR SCENARIO IS POSSIBLE TONIGHT INTO TOMORROW
AS A WAVE CURRENTLY NOTED IN VAPOR IMAGERY OVER NORTHERN MONTANA
DROPS SOUTHEASTWARD AND INTERACTS WITH THE BAROCLINIC ZONE.
RESULTANT FORECAST WILL TREND HIGHER THAN GUIDANCE FOR PRECIP
CHANCES TOMORROW ESPECIALLY ACROSS FAR EASTERN OK / WESTERN AR.

A BRIEF LULL IN ACTIVITY IS EXPECTED FRIDAY BEFORE PRECIP CHANCES
AGAIN INCREASE LATE SATURDAY THROUGH AT LEAST SUNDAY. THE REMNANT
IMPULSE FROM ODILE WILL PUSH INTO THE HIGH PLAINS FRIDAY EVENING
AND INTERACT W/ A SLOW MOVING FRONTAL BOUNDARY SATURDAY AND
SATURDAY NIGHT. THE EXTREMELY MOIST AIRMASS CURRENTLY RESIDING
OVER SOUTHERN TX WILL ALSO BE DRAWN NORTH AND EASTWARD ALONG THE
BOUNDARY. THE EXACT INTERACTION W/ THESE FEATURES HAS YET TO BE
DETERMINED...HOWEVER THERE HAS BEEN A TREND THAT THE REMNANT
CIRCULATION STALLS TO OUR WEST AND THUS THE HEAVIER PRECIP AXIS.
WHILE PRECIP CHANCES WILL REMAIN RATHER GOOD FOR MUCH OF THE
REGION GIVEN THE DEEP MOISTURE AND FRONTAL BOUNDARY...THE LOCATION
OF THE HEAVIEST RAINS HAS YET TO BE EXACTLY DETERMINED.

ONCE THE WEEKEND FRONTAL BOUNDARY PASSES A PERIOD OF SEASONABLY
COOL AND DRY CONDITIONS LOOK LIKELY FOR THE FIRST PART OF NEXT
WEEK.

ARKANSAS DURING THE WEEKEND. THUNDERSTORM CHANCES INCREASE DURING
THE DAY SATURDAY AND CONTINUE INTO SUNDAY EVENING BEFORE THE COLD
FRONT EXITS THE REGION. TROPICAL MOISTURE FROM THE REMNANTS OF
HURRICANE ODILE IS EXPECTED TO LIFT INTO THE PLAINS AND MERGE WITH
THE APPROACHING COLD FRONT...CREATING THE POTENTIAL FOR HEAVY
RAINFALL OVER EASTERN OKLAHOMA AND NORTHWEST ARKANSAS SATURDAY
INTO SUNDAY.
