Time	Report	Where	Remark

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

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

Shreveport, LA (KBAD), launched 12:00Z, 3.9 hours before the alert went out and 138 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.

Area forecast discussion, Apr 11, 10:29 AM CDT, 22 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
1029 AM CDT MON APR 11 2016

.DISCUSSION...
ONGOING CONVECTION EXPECTED TO CONTINUE AND BECOME MORE WIDESPREAD
ACROSS THE REGION TODAY...AS A SHORTWAVE AND ITS ASSOCIATED SFC
BOUNDARIES MOVE EWD. SEVERE STORMS ARE LIKELY AS THE DAY GOES
ON...AND SPC HAS UPGRADED THE RISK TO ENHANCED FOR OUR ENTIRE CWA.
AS FAR AS THE GRIDS ARE CONCERNED...ONLY A FEW MINOR ADJUSTMENTS
TO POPS FOR THIS AFTERNOON...MAINLY TO RAISE OVER OUR EXTREME NRN
AND SRN AREAS. CONTINUED ONGOING SVR WORDING FOR ALL AREAS.
OTHERWISE...NO OTHER CHANGES APPEAR NECESSARY ATTM. /12/

&&

.PREV DISCUSSION... /ISSUED 702 AM CDT MON APR 11 2016/

AVIATION...
LOW MVFR/IFR CIGS HAVE DEVELOPED ACROSS MUCH OF THE REGION THIS
MORNING...AND WILL PERSIST THROUGH THE MORNING WITH ONLY SLOW
IMPROVEMENT EXPECTED THIS AFTERNOON. SCT -SHRA WITH ISOLATED -TSRA
HAVE ALSO DEVELOPED ACROSS NE TX/EXTREME NRN LA/SW AR/SE OK...AND
SHOULD CONTINUE THROUGH THE AFTERNOON...WITH ADDITIONAL
DEVELOPMENT EXPECTED FARTHER S ACROSS DEEP E TX/NCNTRL LA. AN
OUTFLOW BNDRY FROM AN EARLIER CONVECTIVE COMPLEX HAS BECOME
STATIONARY JUST N OF THE RED RIVER OF SRN OK INTO SE OK/WRN
AR...AND WILL BE THE FOCUS FOR ADDITIONAL SCT CONVECTION LATER
TODAY AHEAD OF A SHORTWAVE THAT WILL APPROACH THESE AREAS FROM
THE W LATER TODAY. HAVE INSERTED VCSH FOR MOST TERMINALS THIS
MORNING TO ACCOUNT FOR THE ONGOING DEVELOPMENT...AND HAVE DELAYED
VCTS MENTION UNTIL MIDDAY/AFTERNOON ONCE BETTER HEATING/DESTABILIZATION
IS REALIZED. HOWEVER...ADDITIONAL AMENDMENTS WILL BE NECESSARY
ONCE CONVECTIVE TRENDS ARE BETTER DETERMINED. WHILE VFR CONDITIONS
MAY RETURN LATER THIS AFTERNOON OVER E TX/N LA...MVFR CIGS SHOULD
RETURN THIS EVENING AS THE CONVECTION ALONG A COLD FRONT BEGINS TO
SHIFT SSE TO THE I-20 CORRIDOR BY 06Z...WITH CIGS BECOMING IFR
WITH THE FROPA. THE CONVECTION SHOULD FINALLY DIMINISH LATE
TONIGHT AS THE SHORTWAVE EXITS THE REGION AND THE AIR MASS
STABILIZES. SHOULD SEE SOME SLOW IMPROVEMENTS TO CIGS FROM N TO S
BY/JUST AFTER 12Z TUESDAY. S WINDS 10-15KTS WITH GUSTS TO 20KTS BY
AFTERNOON OVER E TX/N LA...SHOULD DIMINISH AFTER 00Z AND BECOME
NNE 7-11KTS WITH THE FROPA LATE TONIGHT. /15/

PREV DISCUSSION... /ISSUED 518 AM CDT MON APR 11 2016/

DISCUSSION...
SCATTERED SHOWERS WITH ISOLATED THUNDER IN SE OK NEAR VALIANT
MOVING ENE AROUND 40 MPH AND ON THE LA/AR STATE LINE NEAR
HAYNESVILLE MOVING NE AT 50 MPH. A NICE BOUNDARY IS DRAPED NW OF
THE I-30 CORRIDOR. A NEW CLUSTER OF THUNDERSTORMS IS INCREASING IN
COVERAGE AND INTENSITY OVER N TX S OF WICHITA FALLS AND SHOULD
RIDE ALONG THE OUTFLOW BOUNDARY FROM LAST NIGHT/S CONVECTION. THE
SURFACE COLD FRONT IS PUSHING INTO THE PANHANDLES NOW AND WILL
SLOW MOVE IN OUR DIRECTION. THE WINDS IN THE FORECAST PERHAPS
BETTER DEPICT A BACK DOOR PUSH FOR THE COOLER AIR AS THE CENTER OF
THE HIGH KEEPS TO THE MIDWEST U.S.

THE SPC HAS EXPANDED THE DAY ONE FOR A LARGER AREA OF OUR CWA NOW
INCLUDED IN THE ENHANCED RISK WITH MUCH OF THE MID SOUTH IN A
LARGE SLIGHT RISK AREA THROUGH THIS TIME TOMORROW MORNING. WE WILL
SEE WHAT THE NEXT UPDATE BRINGS AROUND VALID TIME. THE MODELS HAVE
SOME DECENT CAPE WITH STEEP LAPSE RATES THIS AFTERNOON. OUR
FORECAST WET BULB ZEROS HEIGHTS ARE BELOW 10KFT AND VERY LARGE TO
LARGE HAIL WILL BE LIKELY IN THE AFTERNOON PUSH INTO THE EVENING
HOURS. DAMAGING WINDS AND STILL A BRIEF TORNADIC WINDOW STILL ALL
LOOM DEPENDING ON HOW THE EVOLUTION OF TS ACTIVITY DEVELOPS.
SEVERE WORDING HAS BEEN ADDED TO OUR LIKELY/DEFINITE ZONE
GROUPINGS FROM 18-06Z. WE WILL BE DOING AN 18Z SOUNDING LATER
TODAY TO SEE HOW THINGS ARE PANNING OUT WITH HEATING WELL
UNDERWAY. WE ARE ALREADY WARMER THAN GUIDANCE AND NOT WARM ENOUGH
IF WE CAN BREAK OUT WITH SOME PERIODS OF SUN.

THE WPC QPF IS STILL ABOUT THE SAME WITH A HALF TO INCH OF
RAINFALL FOR OUR WEST WITH ONE TO TWO INCH AMOUNTS WIDESPREAD AND
STILL SOME HIGHER TWO INCH AMOUNTS IN SE AR. THE CONVECTIVE
NATURE COULD MAKE FOR FEAST OR FAMINE IN BACKYARD BUCKETS. THE
COLD FRONT WILL SLOWLY FILTER IN SOUTH OF I-20 BY THIS TIME
TUESDAY. THE GFS IS DOING A FAIR JOB SHOWING THE SURFACE LOW
MOVING EAST WITH A TRAILING INVERTED TROUGH LAGGING BEHIND. SO
THE SLOWER MOVEMENT OF THE BOUNDARY WILL HELP TO REFOCUS QPF
DURING THE OVERNIGHT WITH STILL LOTS OF ENERGY ALOFT AND BOUNDARY
INTERACTIONS ADDING TO DEVELOPMENT AS WELL. HOPEFULLY WE CAN SOME
HOW ALL GET A GOOD WASH DOWN NOW THAT THE SPRING POLLEN PUSH IS
WINDING DOWN.

THE REMAINDER OF THE FORECAST IS PRETTY MUCH IN TACK WITH SOME
MIDWEEK QPF AND SLIGHTLY COOLER TEMPERATURES. THE OUTLOOK FOR MUCH
MORE APRIL SHOWERS AND NEEDED RAINFALL IS SHAPING FOR US BY THE
MIDDLE OF NEXT WEEK WITH A MOIST SOUTHWEST FLOW AS A SLOW MOVING
CLOSED LOW DRIFTS ACROSS THE PLAINS. /24/
