INCREASED POPS TO ACCOUNT FOR CURRENT TREND. A DECENT BAND OF
THUNDERSTORMS HAS DEVELOPED ALONG A NARROW BOUNDARY OF LL
CONVERGENCE... WHICH APPEARS TO BE DRIVEN BY THE SOUTHWARD
ADVANCEMENT OF THE SFC HIGH OFF THE EAST CENTRAL PLAINS AND THE
SFC TROUGH EXTENDING EASTWARD FROM WEST TEXAS. LITTLE SUPPORT FROM

THESE STORMS BECOMING SEVERE. WILL NEED TO WATCH FOR POTENTIAL
HYDRO ISSUES... BUT THE LINE APPEARS TO BE MOVING AT A DECENT S/SE
CLIP... BRINING A DECENT AND BENEFICIAL RAIN TO TEXOMA.
