THE REGION HAS OPENED UP AS GULF MOISTURE SURGES NORTHWARD INTO
NORTH TEXAS AND LOUISIANA THIS MORNING. NWS RADARS INDICATE

SOUTHWEST LOUISIANA UP TO MONROE IN NORTHEAST LOUISIANA. MORNING

COOLER. WINDS WILL INCREASE AS THE PRESSURE GRADIENT TIGHTENS.

ALL OF THIS IS AHEAD OF A STRONG COLD FRONT THAT WILL PUSH THROUGH
THE REGION AROUND DAYBREAK TOMORROW. STRONG MID AND UPPER LEVEL
