...THERE IS A SLGT RISK OF SVR TSTMS FROM ERN OK...ACROSS SRN MO
INTO CENTRAL AR...

...AR/ERN OK/SRN MO...

BOUNDARY LAYER HAS BEEN SLOW TO MOISTEN ACROSS THE WARM SECTOR FROM
THE ARKLATEX INTO NRN AR AHEAD OF SFC WIND SHIFT.  RESULTANT
THERMODYNAMIC PROFILES CURRENTLY EXHIBIT WEAKLY CAPPED...YET ONLY
MARGINALLY UNSTABLE PARCELS...THOUGH LAPSE RATES ARE QUITE STEEP. 
LATEST VIS IMAGERY SUGGESTS SHALLOW CONVECTION IS SLOWLY DEEPENING
ACROSS WRN-NRN AR...MOST LIKELY STUNTED BY WEAK LOW LEVEL
CONVERGENCE.  IT APPEARS DEEP CONVECTION WILL BECOME MORE LIKELY AS
LARGE SCALE ASCENT AND BACKING LLJ INCREASE ACROSS ERN OK INTO WRN
AR LATER TONIGHT.  IN THE SHORT TERM...ISOLATED THUNDERSTORMS MAY
EVOLVE ACROSS NRN AR BEFORE SPREADING EWD INTO WRN TN. ELEVATED
INSTABILITY WILL GRADUALLY INCREASE AFTER MIDNIGHT AND SECONDARY
DEVELOPMENT IS LIKELY IN RESPONSE TO HEIGHT FALLS ACROSS WRN
PORTIONS OF THE SLIGHT RISK AREA.  LARGE HAIL SHOULD BE THE PRIMARY
SEVERE THREAT.
