SATELLITE AND RADAR IMAGERY INDICATES A SUBSTANTIAL
AREA OF SHOWERS AND THUNDERSTORMS HAS DEVELOPED OVER THE GULF AND
IT APPEARS A WEAK SURFACE LOW MAY HAVE DEVELOPED AND IS RIDING
TOWARDS THE AREA CURRENTLY.
It's probably no more than a weak low along a surface boundary, but the radar presentation has really blown up throughout the day.
