PERSISTS ACROSS THE NRN GULF/GULF COAST REGION RESULTING IN
ELY/ENELY LOW-LEVEL FLOW ACROSS THE GULF OF MEXICO.
WHILE THE MARGINAL MOISTURE COMBINED WITH RELATIVELY COLD MID-LEVEL
TEMPERATURES /AROUND -18 C AT H5/ SHOULD YIELD AMPLE AFTERNOON CAPE
FOR THE DEVELOPMENT OF SHOWERS AND THUNDERSTORMS INVOF THE
