AREAS AFFECTED...PARTS OF SOUTH-CENTRAL LOUISIANA INTO FAR SOUTHWEST
MISSISSIPPI
CONCERNING...TORNADO WATCH 632...
VALID 260637Z - 260800Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 632 CONTINUES.
SUMMARY...THE RISK OF A COUPLE TORNADOES AND LOCALLY DAMAGING GUSTS
WILL CONTINUE SPREADING EASTWARD ACROSS SOUTHERN LOUISIANA AND FAR
SOUTHERN MISSISSIPPI EARLY THIS MORNING -- WITHIN TORNADO WATCH 632.
DISCUSSION...AN EARLIER BAND OF CONVECTION HAS LARGELY DEVOLVED INTO
DISORGANIZED SEMI-DISCRETE ELEMENTS WHILE TRACKING SLOWLY EASTWARD
ACROSS SOUTHERN LA THIS MORNING. AHEAD OF THIS ACTIVITY, THE HDC VWP
IS SAMPLING 40-KT FLOW BETWEEN 0.5 AND 1 KM. THIS FLOW FIELD IS
COINCIDENT WITH AROUND 2-MB SURFACE PRESSURE FALLS AND RESULTING IN
INCREASED LOW-LEVEL HODOGRAPH CURVATURE COMPARED TO THE EARLIER
PRE-CONVECTIVE ENVIRONMENT FARTHER WEST. WHILE THE CONTINUED MESSY
STORM MODE AND ONLY MODEST LOW-LEVEL MASS RESPONSE CONTINUE TO CAST
UNCERTAINTY ON THE OVERALL SEVERE RISK, THE IMPLIED LOW-LEVEL
STREAMWISE VORTICITY AND MOIST BOUNDARY LAYER (LOWER 70S DEWPOINTS)
WILL CONTINUE TO SUPPORT A RISK OF A COUPLE TORNADOES WITH EASTWARD
EXTENT.
