SUMMARY...THE POTENTIAL FOR TORNADOES WILL CONTINUE TO FOCUS
PRIMARILY ACROSS SOUTHEAST LOUISIANA NEAR/TO THE SOUTH OF I-12/I-10
OVER THE NEXT SEVERAL HOURS (PREDAWN).

WSR-88D DATA INDICATE A CONTINUED STRENGTHENING OF
SOUTH-SOUTHWESTERLY WINDS (30-40 KT) IN THE LOWEST 1-2 KM AGL ACROSS
SOUTHERN PORTIONS OF LOUISIANA AND MISSISSIPPI. THIS SAME TREND IS

STRENGTHENING AND GRADUAL EAST-NORTHEASTWARD EXPANSION OF THE
STRONGER LOW-LEVEL WIND FIELD. THE MOST BUOYANT LOW-LEVEL AIR MASS
