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 Fort Worth, TX wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 12, 3:20 PM CDT, 21 minutes earlier.

Area forecast discussion, Jun 12, 3:20 PM CDT, 21 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FORT WORTH TX
320 PM CDT TUE JUN 12 2012

.DISCUSSION...

WILL BE REMOVING THE NORTHWEST AND NORTHERN COUNTIES OUT OF THE
WATCH.

SEVERE THUNDERSTORM POTENTIAL WILL CONTINUE OVER THE SOUTHERN
HALF OF THE CWA THE REST OF THE AFTERNOON AND INTO THE EARLY
EVENING HOURS AS CONVECTION MOVES THROUGH AIR RICH IN CAPE AND
INSTABILITY. LARGE HAIL AND DAMAGING WINDS REMAIN THE MOST LIKELY
SEVERE WEATHER THREAT.

FOR TONIGHT...NEW CONVECTION FIRING UPSTREAM IN THE NEW
MEXICO/COLORADO ROCKIES IS EXPECTED TO MOVE SOUTHEAST INTO THE
PANHANDLE THIS EVENING AND DEVELOP INTO AN MCS. THIS WILL EVENTUALLY
WORK INTO THE WESTERN CWA NEAR DAYBREAK AND ACROSS THE REMAINING
CWA WEDNESDAY MORNING THROUGH MIDDAY OR EARLY AFTERNOON. ONCE
AGAIN...DEPENDING ON HOW MUCH THE AIR GETS WORKED OVER...ENOUGH
INSTABILITY MAY REMAIN FOR A FEW STRONG TO SEVERE THUNDERSTORMS.
WE WILL LINGER LOW POPS ACROSS THE CWA WEDNESDAY AFTERNOON AS
OUTFLOW BOUNDARIES MAY BE PRESENT AND BECOME THE FOCUS FOR LOW
LEVEL CONVERGENCE AND STORM DEVELOPMENT.

SOME MODEL SOLUTIONS LINGER SOME STORM POTENTIAL INTO
THURSDAY...BUT HAVE LOW CONFIDENCE THAT MUCH IF ANY WILL OCCUR AS
THE STORM TRACK AND SURFACE BOUNDARIES MOVE NORTH OF THE REGION.

AS FOR TEMPERATURES...CONVECTION AND OUTFLOW WILL MAKE IT
DIFFICULT TO SELECT ACCURATE LOWS OVER THE SOUTHERN TONIGHT...AND
CIRRUS SHIELD WILL AFFECT HOSE IN THE NORTH. LOWER TO MID 70S IS
THE BEST GUESS...HOWEVER A FEW LOCATIONS MAY SEE UPPER 60S. DECIDE TO
HOLD MAX TEMPS NEAR NORMAL AND MIN TEMPS SLIGHTLY ABOVE NORMAL
INTO THE WEEKEND THEN INCHING UP A FEW DEGREES EARLY NEXT WEEK.
