.PREV DISCUSSION... /ISSUED 913 PM CDT SUN MAR 29 2015/

DISCUSSION...
NO CONVECTIVE DEVELOPMENT AS OF 9 PM THIS EVENING. WILL UPDATE
ZONES AND LOWER POPS A LITTLE. BEST CHANCE FOR THE CONVECTION
WILL BE AFTER MIDNIGHT...ACROSS SOUTH CENTRAL ARKANSAS AND POINTS
EAST. THIS DECISION IS BASED ON A STABLE LOWER ATMOSPHERE AND
LACK OF MOISTURE. CURRENT TEMPS AND FORECAST MINS LOOK GOOD. DID
MAKE SOME ADJUSTMENTS ON QFP AMOUNTS...MAINLY FOR THIS EVENING DUE
TO THE LACK OF RAIN.

NO OTHER CHANGES ATTM.

DISCUSSION...
LAKE WIND ADVISORY REMAINS IN EFFECT THROUGH 4 PM. CURRENT WIND
SPEEDS ACROSS THE REGION RANGING FROM 20 MPH ACROSS DEEP EAST
TEXAS TO AROUND 10 MPH ACROSS SOUTHERN ARKANSAS. WINDS TO SETTLE
LATE IN THE AFTERNOON AS PRESSURE GRADIENT RELAXES AND A FRONTAL
BOUNDARY MOVES INTO THE REGION. COLD FRONT EXTENDS FROM A CLOSED
LOW IN NORTH CENTRAL TEXAS TO CENTRAL OKLAHOMA WHILE ANOTHER WEAK
BOUNDARY EXTENDS ACROSS THE RED RIVER OF NORTH TEXAS AND INTO
SOUTHERN ARKANSAS. COULD SEE A MARGINAL SEVERE WEATHER THREAT THIS
EVENING INTO THE OVERNIGHT HOURS ALONG THE SOUTHERN-MOST BOUNDARY
AFFECTING PORTIONS OF SOUTHEAST OKLAHOMA...NORTHEAST TEXAS AND
SOUTHERN ARKANSAS AS AN UPPER-LEVEL DISTURBANCE SLIDES EAST ACROSS
THE REGION. LARGE HAIL TO BE THE LARGEST THREAT. STORMS TO
DISSIPATE LATE TONIGHT WITH LINGERING SHOWERS POSSIBLE BY
DAYBREAK.

NO SIGNIFICANT AIRMASS MODIFICATION THROUGHOUT MUCH OF THE WORK
WEEK. TEMPERATURES TO RANGE FROM HIGHS IN THE 70S AND LOWER 80S TO
LOWS IN THE 60S. HOWEVER...A SERIES OF UPPER-LEVEL DISTURBANCES
INTERACTING WITH STALLED FRONTAL BOUNDARY ACROSS THE REGION TO
ALLOW FOR A CHANCE OF SHOWERS AND THUNDERSTORMS EACH DAY THIS
WEEK. THE MOST SIGNIFICANT CHANCES FOR CONVECTION WILL BE LATE
FRIDAY NIGHT INTO SATURDAY AS A STRONG COLD FRONT WITH ASSOCIATED
UPPER-TROUGH SURGES SOUTH. HIGH PRESSURE REBUILDING BEHIND THE
FRONT TO BRING COOLER TEMPS TO THE REGION WITH HIGHS IN THE 60S
AND 70S AND LOWS IN THE 40S THROUGH THE WEEKEND. /05/
