.PREV DISCUSSION... /ISSUED 1115 AM CDT THU MAR 17 2016/

DISCUSSION...
ONGOING CONVECTION MAINLY ALONG THE I-30 CORRIDOR HAS PRODUCED
A FEW STRONG TO SEVERE STORMS...MAINLY WITH LARGE HAIL AS STEEP
MID LEVEL LAPSE RATES HAVE RESULTED IN VERY COLD TEMPERATURES
ALOFT. FORCING MECHANISM IS HARD TO PIN DOWN BUT IT APPEARS THERE
MAY BE SOME EMBEDDED UPPER LEVEL ENERGY WHICH IS CONTRIBUTING TO
THESE ENHANCED TSTMS. FARTHER SOUTH...A STATIONARY BNDRY REMAINS
ANCHORED ACROSS PARTS OF DEEP E TX AND INTO ADJACENT W CNTRL LA.
EXPECT ADDITIONAL SHWRS AND TSTMS TO GET GOING LATER TODAY AS
HEATING ERODES THE LOW LEVEL INVERSION NEAR AND ALONG THE BNDRY
WITH INSTABILITY INCREASING STEADILY THROUGHOUT THE AFTERNOON.
A MARGINAL TO SLIGHT RISK SEVERE POTENTIAL COVERS MUCH OF THE
REGION AND LARGE HAIL WILL CONTINUE TO BE THE PRIMARY THREAT BUT
WE CANNOT COMPLETELY RULE OUT THE DAMAGING WIND AND ISOLATED
TORNADO THREAT. FOR THE UPDATE THIS MORNING...HAVE INCLUDED SEVERE
WORDING ACROSS THE BOARD FOR ALL AREAS BUT MAINLY FOCUSING SOUTH
OF THE I-30 CORRIDOR FOR THE REMAINDER OF TODAY. HAVE MAINTAINED
PREVIOUS HIGH TEMPERATURES BUT SOME AREAS MAY STRUGGLE TO REACH
FORECAST HIGHS IF CLOUD COVER DOES NOT AT LEAST PARTIALLY BREAK.
THE REMAINDER OF THE FORECAST WAS ALSO LET INTACT. UPDATED TEXT
PRODUCTS HAVE ALREADY BEEN SENT. /19/

PREV DISCUSSION... /ISSUED 659 AM CDT THU MAR 17 2016/

AVIATION...
A WEAK SFC FRONT EXTENDS FROM CNTRL TX ESE INTO DEEP E TX AND
CNTRL LA THIS MORNING...WITH THE BNDRY EXPECTED TO REMAIN NEARLY
STATIONARY OR DRIFT SLIGHTLY N TODAY TO NEAR/JUST S OF THE I-20
CORRIDOR. MVFR CIGS HAVE DEVELOPED OVER N AND ECNTRL TX NEAR THIS
FRONT THIS MORNING...AND WILL AFFECT THE TYR/GGG TERMINALS THIS
MORNING BUT MAY SCATTER OUT/LIFT BY LATE MORNING. AREAS OF VLIFR
CIGS/FG HAVE DEVELOPED OVER SE TX/SRN AND CNTRL LA...INCLUDING THE
LFK TERMINAL CLOSER TO THE FRONT...AND COULD LINGER THROUGH MUCH
OF THE MORNING BEFORE LIFTING. SHOULD SEE SCT CONVECTION
DEVELOP/SPREAD E FROM N TX ALONG/N OF THE FRONT TODAY...AFFECTING
THE AREA TERMINALS LATER THIS MORNING THROUGH MUCH OF THE
AFTERNOON. GIVEN THE LOW CONFIDENCE OF COVERAGE/TIMING...HAVE
PREVAILED MENTION OF VCTS FOR THE AFFECTED TERMINALS...WITH THE
CONVECTION EXPECTED TO DIMINISH FROM W TO E LATER THIS
AFTERNOON/EVENING. ADDITIONAL REDEVELOPMENT WILL BE POSSIBLE NEAR
THE FRONT OVERNIGHT...AS THE FRONT LIFTS SLOWLY N TO THE I-20
CORRIDOR. CIGS SHOULD BECOME LOW MVFR/IFR NEAR/S OF THE FRONT

DISCUSSION...
A WEAK SURFACE BOUNDARY EXTENDING ACROSS DEEP EAST TEXAS TOWARD
MONROE WILL BE THE FOCUS FOR CONVECTION LATER TODAY. DESPITE
MAINLY ZONAL FLOW ACROSS THE REGION...AN UPPER-LEVEL DISTURBANCE
MOVING ACROSS THE REGION IN THE VICINITY OF THE NEARLY STATIONARY
FRONTAL BOUNDARY WILL GENERATE SUFFICIENT LIFT TO ALLOW FOR
SHOWERS AND THUNDERSTORMS. INSTABILITY WILL BE ENHANCED BY
SUFFICIENT MOISTURE SOUTH OF THE FRONTAL BOUNDARY. THE MAIN
THREAT WILL BE HAIL...WITH DAMAGING WINDS A SECONDARY THREAT. THE
STRONGEST CONVECTION WILL LIKELY OCCUR DURING THE AFTERNOON HOURS
AS THE BOUNDARY LAYER DESTABILIZES.

RAINFALL TOTALS WILL AVERAGE AN INCH OR LESS TODAY MAINLY ALONG
AND SOUTH OF INTERSTATE 20. HOWEVER...ISOLATED AMOUNTS OF AS HIGH
AS 2 INCHES MAY BE POSSIBLE IN THE STRONGER CONVECTION ACROSS
PORTIONS OF NORTH-CENTRAL AND NORTHEAST LOUISIANA.

SCATTERED SHOWERS AND THUNDERSTORMS REMAIN POSSIBLE THROUGH THE
REMAINDER OF THE WORK WEEK INTO THE EARLY PART OF THE WEEKEND DUE
TO THE LINGERING FRONTAL BOUNDARY PARKED ALONG AND SOUTH OF
INTERSTATE 20. NORTHWEST FLOW BEHIND A LONGWAVE TROUGH TO BUILD
ACROSS THE REGION ON SATURDAY ALLOWING FOR IMPROVING CONDITIONS.

MUCH COOLER TEMPERATURES EXPECTED LATE IN THE WEEKEND THROUGH THE
EARLY PART OF THE WORK WEEK WITH HIGHS IN THE 50S AND 60S AND LOWS
IN THE 30S AND 40S. OTHERWISE...A GRADUAL WARMING TREND EXPECTED
THROUGH THE MIDDLE OF THE WORK WEEK. /05/
