AREAS AFFECTED...NRN/CNTRL AR...NW MS

CONCERNING...SEVERE THUNDERSTORM WATCH 209...

VALID 291434Z - 291630Z

SEVERE THREAT CONTINUES...WW 209 LIKELY WILL BE REPLACED WITH NEW WW
TO BETTER REFLECT THREAT AREA.

SHORT WAVE PROGRESSING INTO THE OKLAHOMA/TEXAS PANHANDLE REGION IS
BECOMING SHEARED AS IT PROGRESSES INTO CONFLUENCE BETWEEN NORTHERN
AND SOUTHERN BRANCHES OF WESTERLIES.  PRIMARY SOUTHERN BRANCH SHORT
WAVE TROUGH IS STILL WELL UPSTREAM....ACROSS THE SOUTHERN PLATEAU...
AND...IN ADVANCE OF THIS FEATURE...MID-LEVEL WARMING MAY ULTIMATELY
LEAD TO DEMISE OF ONGOING CONVECTIVE CLUSTER ACROSS CENTRAL
ARKANSAS.  HOWEVER...MODELS SUGGEST SOUTHERLY LOW-LEVEL JET WILL
BACK TO A MORE SOUTHERLY COMPONENT THROUGH MID DAY...FROM EASTERN
TEXAS INTO CENTRAL ARKANSAS.  THIS MAY PROVIDE SUFFICIENT FORCING
ABOVE RAIN-COOLED OUTFLOW TO MAINTAIN VIGOROUS CONVECTIVE
DEVELOPMENT AT LEAST ANOTHER FEW HOURS...NORTHWEST THROUGH NORTHEAST
OF LITTLE ROCK.
