Severe Thunderstorm Warning 214, NWS Shreveport, LA

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
414 PM CDT MON JUN 29 2015

.DISCUSSION...
A SHORTWAVE TROUGH DIVING SEWD THROUGH NRN AR HAS PROVIDED
SUFFICIENT VERTICAL ASCENT FOR SCATTERED SHWRS/TSTMS ONCE AGAIN
TODAY. THIS ACTIVITY IS GENERALLY BEING FOCUSED ALONG AND SOUTH OF
I-20 ALONG OLD OUTFLOW BOUNDARIES FROM PREVIOUS CONVECTION.
ADDITIONAL SHWRS/TSTMS ARE DEVELOPING FARTHER NORTH ACROSS OK
ALONG A WEAK FRONTAL BOUNDARY. THIS ACTIVITY SHOULD MOVE INTO THE
ARKLATEX MAINLY AFTER MIDNIGHT TONIGHT. CONVECTIVE COVERAGE SHOULD
BE GREATER DURING THE DAY TUESDAY AS THE SHORTWAVE MOVES INTO THE
LOWER MS VALLEY/SERN CONUS. GIVEN THE AMOUNT OF INSTABILITY IN
PLACE...A COUPLE OF SEVERE STORMS POSING A DAMAGING WIND THREAT
CANNOT BE RULED OUT ON TUESDAY. RAIN CHANCES SHOULD DIMINISH LATE
TUESDAY EVENING/TUESDAY NIGHT AS THE SHORTWAVE MOVES AWAY AND
DAYTIME HEATING WANES.

NWLY FLOW ALOFT WILL PERSIST FOR MUCH OF THE FORECAST PERIOD.
ISOLATED TO WIDELY SCATTERED DIURNAL CONVECTION WILL BE POSSIBLE
EACH DAY. A STRONGER UPPER TROUGH SHOULD MOVE INTO THE MIDWEST
WHILE ANOTHER SHORTWAVE TROUGH AND COLD FRONT MOVE INTO THE
SOUTHERN PLAINS. THIS SHOULD PROVIDE BETTER CHANCES FOR ORGANIZED
CONVECTION FRIDAY AND SATURDAY MAINLY NORTH OF I-20. THIS WILL
MAINLY BE IN THE FORM OF SCATTERED TSTMS OR POSSIBLY LINEAR
COMPLEXES THAT FORM ALONG THE FRONT AND THEN MOVE SOUTHEAST
TOWARDS THE AREA FROM OK/AR.

THE WRN CONUS RIDGE IS PROGGED TO FINALLY MOVE EAST AND BUILD OVER
THE PLAINS EARLY NEXT WEEK. THIS SHOULD BRING MOST OF OUR RAIN
CHANCES TO AN END AND FINALLY SET THE STAGE FOR HOT AND DRY
SUMMERTIME CONDITIONS. /09/
