A moist and unstable airmass developed during the late afternoon and evening hours of July 14th across Northeast Texas. The combination of a weak upper level disturbance and a remnant outflow boundary from earlier convection in Southwest Arkansas and Northern Louisiana helped to spark widely scattered showers and thunderstorms across Northeast Texas.

The episode as NWS SHV wrote it up.
A moist and unstable airmass developed during the late afternoon and evening hours of July 14th across Northeast Texas. The combination of a weak upper level disturbance and a remnant outflow boundary from earlier convection in Southwest Arkansas and Northern Louisiana helped to spark widely scattered showers and thunderstorms across Northeast Texas. One of these storms was strong enough to down a tree in Smith County.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Shreveport, LA wrote its last area forecast discussion before the first event at Jul 14, 2:12 PM CST, 2 hours 38 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
ISSUED BY NATIONAL WEATHER SERVICE FORT WORTH TX
312 PM CDT THU JUL 14 2011
.DISCUSSION...
THIS MORNINGS SHOWERS AND THUNDERSTORMS LEFT MOSTLY CLOUDY SKIES
FOR ALL BUT THE TEXAS COUNTIES. THIS KEPT HIGH TEMPERATURES DOWN
AND PREVENTED THIS AREA FROM REACHING HEAT ADVISORY CRITERIA.
CURRENT VISIBLE SATELLITE IMAGERY SHOWS AN AGITATED CU FIELD IN
EAST TEXAS...WHERE THE SKIES REMAINED MOSTLY CLEAR THIS MORNING AND
HAVE NOW BECOME PARTLY CLOUDY. CURRENT THUNDERSTORM ACTIVITY ALONG
A CLARKSVILLE TO VIVIAN LINE WILL LIKELY CONTINUE ITS SLOW SOUTHERN
PROGRESSION UNTIL JUST AFTER SUNSET. BRIEF HEAVY RAIN AND A FEW
LIGHTNING STRIKES ARE EXPECTED WITH THESE STORMS.
INCREASED COVERAGE OF SHOWERS AND THUNDERSTORMS IS EXPECTED
TOMORROW AS THE UPPER LEVEL RIDGE SHIFTS SLIGHTLY NORTHWARD AND A
WEAK DISTURBANCE MOVES SOUTHWESTWARD AROUND ITS PERIPHERY. THIS
DISTURBANCE...COMBINED WITH PWATS AOA 2.25 INCHES AND WEAK
SURFACE CONVERGENCE...SHOULD ALLOW CONVECTIVE INITIATION BY EARLY
AFTERNOON. WENT WITH LIKELY POPS IN THE CENTRAL LOUISIANA AND
SOUTHEAST TEXAS ZONES...WHICH GRADUALLY TRANSITION TO A SLIGHT
CHANCE IN NORTHEAST TEXAS AND SOUTHEASTERN OKLAHOMA. HIGHS WILL BE
MID TO UPPER 90S WITH DEWPOINT VALUES IN THE MID 70S. THIS WILL
RESULT IN HEAT INDEX VALUES CLOSE TO 105. HOWEVER...A FEW DEGREES
DIFFERENCE IN THE TEMPS OR DEWPOINTS COULD KEEP HEAT INDEX VALUES
BELOW THE ADVISORY CRITERIA OF 105. AS A RESULT...DID NOT ISSUE
A HEAT ADVISORY AND WILL ALLOW MIDNIGHT SHIFT TO MAKE THE FINAL
DECISION.
MOISTURE PROGS ARE NOT AS ROBUST SATURDAY AND THE LACK OF UPPER
SUPPORT SUGGESTS LESS THUNDERSTORM COVERAGE THAN FRIDAY.
HOWEVER...CONDITIONS ARE FAVORABLE FOR FURTHER NORTHWARD
PROGRESSION OF THE SEA BREEZE. THIS WARRANTS CHANCE POPS SOUTH OF A
LUFKIN TO VIVIAN LINE AND SLIGHT CHANCE POPS ELSEWHERE.
THE UPPER LEVEL RIDGE IS EXPECTED TO REMAIN OVER THE CENTRAL
PLAINS UNTIL AT THE MIDDLE OF NEXT WEEK. THIS WILL RESULT IN A
CHANCE OF DIURNAL THUNDERSTORMS EVERYDAY THROUGH WEDNESDAY. HIGHS
WILL CONTINUE TO BE IN THE MID TO UPPER 90S WITH LOWS IN THE MID
70S.

.AVIATION...
CONCERNS...AFTERNOON/EVENING CONVECTION. ALSO...EARLY MORNING
REDUCTIONS IN VSBY.

WHERE TEMPS HAVE REACHED 100. MAY NEED TO ENHANCE CONVECTION IN EAST
TEXAS AND SHREVEPORT TAFS.
LOW CLOUDS WILL EVACUATE THIS EVENING. WITH LIGHT WINDS AND DEW
POINTS IN THE 70S...SOME REDUCTION IN VSBY WILL OCCUR DURING THE
EARLY MORNING HOURS...PARTICULARLY WHERE RAIN FELL TODAY.
