Area forecast discussion, Jun 12, 5:05 AM CDT, 8 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
505 AM CDT TUE JUN 12 2012

.DISCUSSION...
DERECHO POSSIBLY HELD OFF BY MULTIPLE CLUSTERS BEING ABSORBED AND
TREMENDOUS COVERAGE DEVELOPMENT IN THE LAST FEW HOURS...BUT MANY
REPORTS OF TREES DOWN WITH DAMAGING WINDS. SO CLOSE TO WIDESPREAD
ALREADY AND WITH DAYLIGHT COMING...WIDESPREAD MAY TURN OUT TO BE
TRUE. ONLY ONE CLUSTER AHEAD OF THE MAIN PUSH CONTAINED HAIL FOR
BOWIE COUNTY AT 715Z. BY FAR WIND IS THE BIG CONCERN WITH POWER
LINES GOING DOWN AMONGST THE TREES. THIS LOOKS VERY MUCH LIKE
EARLY JUNE OF 2004 EVENT. AND THERE WERE A COUPLE OF NOCTURNAL
EVENTS BACK THEN AND MAY BE MORE COMING FOR US TONIGHT. MODELS DO
STILL BACK OFF OF THE QPF BY LATE WEEK. FOR NOW WILL CONTINUE WITH
CHANCE EXPECTATIONS AND GO LIKELY WHEN IN PROGRESS OR
EMINENT...LIKE THIS MORNING.

THE COLD FRONT IS STILL DRAPED DOWN OVER NW AR AND INTO CENTRAL OK
AND WAVES TO THE SOUTHWEST. GOOD CONDITIONS FOR MORE ACTIVITY OF
THIS SORT TONIGHT. MEANWHILE...WITH ABUNDANT MOISTURE AND WARM
TEMPERATURES...DAYTIME HEATING WILL HAVE A CHANCE FOR DEVELOPMENT
TOO IN THE WAKE OF THIS MORNING/S PUSH FOLLOWING A PERIOD OF
RECOVERY. MAV/MEX GENERALLY ACCEPTABLE AND BLENDED INTO THE
FORECAST. UPDATES TO FOLLOW WITH WATCH EXPIRATION'S AND OR CO/PA
CANCELLATIONS. SEVERE 378 VALID UNTIL 6AM AND 379 UNTIL 11AM LST
RESPECTFULLY. /24/

&&

.AVIATION...
A LARGE AREA OF SHOWERS AND THUNDERSTORMS CONTINUED TO MOVE TO THE
EAST AND SOUTHEAST AROUND 20 KNOTS ACROSS SOUTH CENTRAL ARKANSAS AND
NORTHWEST AND NORTH CENTRAL LOUISIANA...AND EAST AND NORTHEAST TEXAS
NEAR A NASHVILLE TO HOPE...AND CANFIELD ARKANSAS AND SHREVEPORT
/BOSSIER CITY LOUISIANA...AND MARSHALL...TATUM...AND BECKVILLE TEXAS
LINE. TO THE WEST OF THIS LINE WIDESPREAD SHOWERS WITH VERY ISOLATED
THUNDERSTORMS WERE ONGOING. WILL PREVAIL MVFR/IFR FLIGHT CATEGORIES
WITH CEILINGS AND VISIBILITY RESTRICTIONS FOR THE INTERSTATE 30
CORRIDOR OVER ARKANSAS AND TO NEAR AND SOUTH OF THE INTERSTATE 20
CORRIDOR TERMINAL FORECAST SITES OF EAST TEXAS AND NORTH LOUISIANA.
FOR KLFK MVFR CEILINGS AND VISIBILITY RESTRICTIONS WITH LOWER CHANCE
OF SHOWERS AND THUNDERSTORMS. MOST TERMINALS WILL BECOME VFR BETWEEN
12/15 UTC TO 12/19 UTC TODAY...AND MAY SEE SOME ADDITIONAL CEILINGS
AND DEVELOPMENT FOR SHOWERS AND THUNDERSTORMS IN THE AFTERNOON
ACROSS EAST TEXAS INTO NORTHWEST AND NORTH CENTRAL LOUISIANA.
WHERE THE RAINS FALL TODAY THERE WILL BE POSSIBLE PATCHY MIST/BR
BETWEEN 13/08 UTC TO 13/13 UTC. SURFACE WINDS WILL BE STRONG AND
GUSTY WITH THE SHOWERS AND THUNDERSTORMS AND VARIABLE BETWEEN 20 TO
35 KNOTS DROPPING OFF TO 7 TO 12 KNOTS WITH NORTHEAST TO EAST WINDS
NORTH OF INTERSTATE 20 AND SOUTH TO SOUTHEAST SOUTH OF INTERSTATE
