AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
605 PM CDT WED APR 10 2013

.DISCUSSION...
AT 2350Z...COLD FRONT WAS LOCATED FROM JUST WEST OF KELD...TO
HOMER...TO MANY. SCATTERED CONVECTION HAS BEGUN TO DEVELOP AHEAD
OF THE FRONT. TEMPS IN THE WARM SECTOR HAVE SOARED INTO THE LOW
80S WHILE DEWPOINTS HAVE RISEN INTO THE UPPER 60S TO NEAR 70
DEGREES F. THUS...CONDITIONS HAVE BECOME MORE CONDUCIVE FOR SEVERE
CONVECTION AHEAD OF THE FRONT. AFTER COORDINATING WITH SPC AND WFO
JAN...A NEW TOR WATCH HAS BEEN ISSUED FOR UNION CO AR AND N CNTRL
LA THRU 06Z.

FARTHER WEST...TORANDO THREAT HAS DIMINISHED AS THE POST-FRONTAL
CONVECTION IS ELEVATED. CANNOT RULE OUT AN ISOLATED DAMAGING WIND
GUST OR SVR HAIL REPORT WITH THIS ACTIVITY. /09/

.PREV DISCUSSION... /ISSUED 305 PM CDT WED APR 10 2013/

DISCUSSION...
THIS AFTERNOONS WATER VAPOR SATELLITE IMAGERY OFFERS A NICE VIEW
OF THE SHARPLY ELONGATED UPPER TROUGH SPINNING ACROSS THE CENTRAL
UNITED STATES. ALSO NOTICEABLE IS AN AREA OF SHOWERS AND THUNDERSTORMS
EXTENDING FROM EASTERN TEXAS THROUGH THE OHIO RIVER VALLEY.

THE SURFACE BASED COLD FRONT THAT HAS BEEN RESPONSIBLE FOR FALLING
TEMPERATURES TO THE WEST HAS SLOWLY BEEN DRIFTING EASTWARD THIS
AFTERNOON. AS OF 19Z...IT WAS ORIENTED ROUGHLY ALONG A LINE FROM
CONROE TO MARSHALL TEXAS...NORTHWARD TO MENA ARKANSAS. FOR
NOW...HAVE TORNADO WATCH NUMBER 89 IN EFFECT FOR SOUTHWEST
ARKANSAS COUNTIES. AS THE COLD FRONT CONTINUES TO DRIFT EASTWARD...EXPECT
ADDITIONAL ACTIVITY TO DEVELOP IN ITS ADVANCE.

NORTHERN LOUISIANA AND SOUTH CENTRAL ARKANSAS SHOULD HAVE A BETTER
ENVIRONMENT FOR SEVERE WEATHER THIS EVENING. WITH NEARLY 2000
J/KG OF MUCAPE AND 30 KTS OF BULK SHEAR IN PLACE ALREADY...ALL THAT THE
ENVIRONMENT NEEDS IS INTERACTION WITH THE FRONT TO BREAK THE
SMALL CAP IN PLACE ACROSS THOSE AREAS. EXPECT SHOWERS AND
THUNDERSTORMS TO CONGEAL AND FORM INTO MORE OF A SUBSTANTIAL LINE
DURING THE EVENING AND OVERNIGHT HOURS...WITH DAMAGING WINDS BEING
THE PRIMARY SEVERE WEATHER THREAT. OTHER THAN ISOLATED TORNADOES
AND HAIL...HEAVY RAINFALL WILL BE A THREAT THIS EVENING...AS THE
UPPER LEVEL FLOW RUNS SOUTH TO NORTH...NOT PROVIDING MUCH OF AN
EASTWARD KICK TO THE SURFACE FRONT. THIS WILL ALLOW FOR QUITE A
BIT OF TRAINING OF STORMS AND LOCALIZED FLASH FLOODING MAY BE A
POSSIBILITY.

LOOKING TO THE WEST...IN THE POST FRONTAL COOLER AIR
MASS...ELEVATED CONVECTION WILL BE ONGOING THIS EVENING AND
OVERNIGHT. SMALL HAIL MAY BE POSSIBLE WITH THESE THUNDERSTORMS.
RAIN CHANCES WILL GRADUALLY COME TO AN END FOR SOUTHEAST OKLAHOMA
AND NORTHEAST TEXAS BY THURSDAY MORNING...WHILE AREAS FARTHER EAST
MAY BE DEALING WITH SHOWER/THUNDERSTORM ACTIVITY THROUGH THE EARLY AFTERNOON.

A FEW DRY DAYS WILL FOLLOW THIS DEPARTING SYSTEM...WITH SLIGHT
RAIN CHANCES RETURNING LATER THIS WEEKEND AS SOUTHWESTERLY FLOW
USHERS IN A FEW DISTURBANCES TOWARD THE AREA. OTHERWISE...WARMER
TEMPERATURES WILL RETURN FRIDAY. /20/

AVIATION...
THE COLD FRONT IS WAY AHEAD OF SCHEDULE...REMAINING VERY SHALLOW.
THE SFC FRONT EXTENDS FROM KTXK...TO NEAR KSHV...TO NEAR KLFK ATTM
WITH NW10G20KTS DISPLACING S/SE10G20KTS. THE WARM AND UNSTABLE DEEP
S/SW FLOW ALOFT WILL REMAIN FOR HRS OVER THE SFC FRONT KEEPING
ELEVATED SCAT/NUMEROUS TSTMS GOING THIS P.M. WITH HAIL UNTIL THE
UPPER LOW LIFTS OUT. ANY SFC BASED DEVELOPMENT AHEAD OF THE FRONT
MAY HOLD OUT FOR LATE DAY SUN OVER TOLEDO BEND COUNTRY UP INTO KELD
AND EAST. THE SFC FRONT SHOULD BE NEAR A KMLU TO KAEX BY 11/06Z WITH
TSTMS ENDING W TO E 03-09Z. EXPECT STRONG WIND AND SEVERE TURBULENCE
WITH SOME HAIL AND IFR CIGS/VSBY WITH THESE STORMS TODAY. AFTER
FROPA...EXPECT MVFR/IFR CIGS/VSBY IN -RA/BR 09-12Z WITH MVFR CIGS
BECMG SKC BY 15-18Z. /24/
