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 Jul 9, 6:11 PM CDT, 54 minutes earlier.

Area forecast discussion, Jul 9, 6:11 PM CDT, 54 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FORT WORTH TX
611 PM CDT MON JUL 9 2012

.AVIATION...
CONVECTION IS FOCUSING ACROSS BOTH THE SOUTHERN HALF OF NORTH
TEXAS WHERE MULTIPLE OUTFLOW BOUNDARIES ARE INTERACTING...AS WELL
AS NEAR THE RED RIVER IN THE VICINITY OF A WEAK FRONT. ACTIVITY
OVER SOUTHERN COUNTIES WILL AFFECT THE WACO TERMINAL FOR A FEW
MORE HOURS BEFORE DIMINISHING AFTER SUNSET...AND WILL STICK WITH
TS IN THE KACT TAF THROUGH 02Z.

STORMS NEAR THE RED RIVER ARE MOVING SOUTH IN EXCESS OF 20 KTS
BUT DECREASE RAPIDLY IN COVERAGE WEST OF FANNIN COUNTY. THERE
APPEARS TO BE AN AREA OF SUBSIDENCE ON THE BACK EDGE EDGE OF A
PERSISTENT WEAK UPPER TROUGH EXTENDING FROM THE MID MS VALLEY INTO
SOUTHEAST TX. MAY STILL INCLUDE CB WITH VCSH FOR A FEW MORE HOURS
IN THE METROPLEX DUE TO THE PRESENCE OF MESOSCALE BOUNDARIES AND
TEMPS IN THE 90S. THE 18Z RUN OF THE GFS WANTS TO DEVELOP A
NARROW BAND OF CONVECTION AFTER MIDNIGHT ALONG THE FRONT ROUGHLY
ALONG THE I 20 CORRIDOR. NOT READY BUY INTO THIS AT THIS TIME WITH
THE THOUGHT THAT STORMS WILL BE MORE LIKELY TO REDEVELOP
TOMORROW...AS THE SURFACE HEATS UP AND THE FRONT SERVES AS A
SURFACE FOCUS.

.PREV DISCUSSION... /ISSUED 253 PM CDT MON JUL 9 2012/
VERY FEW CHANGES TO THIS PACKAGE. NORTH CENTRAL AND NORTHEAST
ZONES WERE COOLED A BIT BY THIS MORNING/S CONVECTION AND
CURRENTLY SIT IN A STORM FREE AREA SURROUNDED BY DEVELOPING
SHOWERS AND THUNDERSTORMS. HOWEVER...WITH ELEVATED INSTABILITY
CONTINUING AFTER MAX HEATING I CANNOT RULE OUT ANY AREAS FOR
POSSIBLE CONVECTION THIS EVENING AND OVERNIGHT. STORM CHANCES
APPEAR SLIGHTLY LOWER TOMORROW...BUT BY WEDNESDAY/THURSDAY DRIER
AIR MOVES INTO NORTHERN AREAS AND AND CONVECTION SHOULD BE
CONFINED MOSTLY TO AREAS SOUTH OF INTERSTATES 20/30.

GFS CONTINUES WET TREND INTO FRIDAY ACROSS THE AREA...BUT IT
SEEMS TO BE THE WET OUTLIER WITH NAM/EURO PREDICTING DRIER
CONDITIONS. WILL LEAVE LOW POPS CONFINED TO SOUTHEAST ZONES WHERE
COASTAL CONVECTION MAY APPROACH BY LATE AFTERNOON.

WITH DRIER CONDITIONS...A SLOW WARM UP BEGINS DURING THE WEEKEND
AND HIGHS SHOULD REACH MID 90S BY MONDAY.
