Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Lake Charles Mun, LA (KLCH), launched 12:00Z, 9.7 hours before the alert went out and 66 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

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 Lake Charles, LA wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 2, 3:43 PM CDT, 57 minutes earlier.
Area forecast discussion, Jun 2, 3:43 PM CDT, 57 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAKE CHARLES LA 343 PM CDT WED JUN 2 2010 .DISCUSSION... SCATTERED SHOWERS AND THUNDERSTORMS DOT THE RADAR SCOPE ACROSS C AND SC LA...WITH ISOLATED OVER SE TX. A FEW OF THESE ARE PROVING ON THE STRONG TO SEVERE SIDE...WITH HAIL OF 3/4 TO 1 INCH...AND DOWN BURST WINDS OF 40 TO 60 MPH THE PRIMARY THREAT. AS BEEN THE CASE EVERY AFTERNOON/EVENING FOR THE LAST WEEK...AFTERNOON HEATING AND INSTABILITY ALOFT TRIGGERS THE INITIAL STORMS...WITH COLLIDING OUTFLOW BOUNDARIES FORMING THE REST. THESE STORMS SHOULD BEGIN TO TAPER OFF BY SUNSET...BEING COMPLETELY GONE BY 10 PM. THE HIGHER THAN NORMAL RAIN CHANGES OVER LA IS ATTRIBUTED TO A SW TO NE ORIENTED TROF ALOFT INCREASING INSTABILITY DURING THE MAX HEATING OF THE DAY. THIS TROF IS EXPECTED TO RETROGRADE W AND ACTUALLY CUT OFF INTO A MID/UPPER LOW SOMEWHERE ALONG THE TX COAST. THE NAM IS FURTHER SW...STILL LEAVING THE TROF AXIS OVER OUR REGION...WHILE THE GFS CUTS OFF THE LOW ACROSS THE UPPER TX COAST. ANY WAY...THE INSTABILITY WILL BE SOMEWHAT INCREASED AND FURTHER W ON THU & FRI...YIELDING A BETTER THAN AVERAGE (40-50%) CHANCE OF SHRA/TSRA. BY SAT...WE ARE HOPING FOR EXCELLENT WEATHER FOR THE NWS LAKE CHARLES PUBLIC OPEN HOUSE FROM 10 AM TO 2 PM. HOWEVER...WE WILL LIKELY BE ON THE EDGE OF THE EXPECTED LIFTING MID/UPPER LOW/TROF OVER THE COASTAL WATERS INTO SC LA...AND THE BUILDING MID/UPPER RIDGE FROM TX. THUS...WENT HIGHER FOR POPS FOR C AND SC LA...(40%) BUT SHOULD BE ENDING EARLIER IN THE AFTERNOON AS THE RIDGE BUILDS SE. FOR W LA AND SE TX...COULD SEE 20-30% COVERAGE...BUT STILL OPEN FOR DEBATE. NOW FOR INLAND SE TX...WILL BE LUCKY TO SEE A FEW SHOWERS...BUT TEMPS SOARING INTO THE UPPER 90S. FOR MON & TUE...THE EASTERN SIDE OF THE MID/UPPER RIDGE WILL BE ON TOP OF THE REGION...WITH LIMITED RAIN CHANCES (LESS THAN 10%)...AND MID/UPPER 90S ALONG THE I-10 CORRIDOR...AND LIKELY 100 NORTH OF US-190. LOWS WILL BE IN THE MID/UPPER 70S...WITH LOWER 80S ALONG THE IMMEDIATE COAST. BY WED...THE GFS ADVERTISES A BROAD TROF ERODING THE MID/UPPER HIGH A BIT TO ACTUALLY DRAG A FRONT SOUTHWARD...STALLING JUST NORTH OF THE REGION. THIS MAY GIVE US A SLIGHT CHANCE OF SHRA/TSRA FOR WED AFTERNOON. HOWEVER...THE ECMWF SHOWS A MUCH WEAKER TROF OVER THE MIDWEST...WITH OUR AREA REMAINING UNDER THE UPPER HIGH.
