CONCERNING...TORNADO WATCH 598...
VALID 310205Z - 310300Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 598 CONTINUES.
SUMMARY...THE TORNADO THREAT ACROSS MS WILL LIKELY CONTINUE LATE
THIS EVENING LASTING INTO THE OVERNIGHT PERIOD. A NEW TORNADO WATCH
WILL NEED TO BE ISSUED PRIOR TO 03Z ACROSS PARTS OF MS.
DISCUSSION...THE CENTER OF TROPICAL DEPRESSION ISAAC IS LOCATED IN
SRN AR WITH SEVERAL DISTINCT BUT VERY NARROW RAINBANDS EXTENDING SWD
ACROSS MS. MESOANALYSIS SUGGESTS THE STRONGEST LOW-LEVEL FLOW IS
PRESENT FROM ABOUT 100 STATUTE MILES NORTH OF ISAACS CENTER WRAPPING
SEWD INTO NRN AND WRN MS ON THE NE QUADRANT OF ISAAC. REGIONAL
WSR-88D VWPS ALONG WITH THE JACKSON 00Z SOUNDING SHOW 50 TO 55 KT OF
FLOW IN THE 1 TO 3 KM LAYER WITH SOME BACKING NEAR THE SFC. THIS
WIND PROFILE ALONG WITH SFC DEWPOINTS IN THE LOWER TO MID 70S F AND
LCL HEIGHTS AROUND 500 METERS SHOULD BE FAVORABLE FOR LOW-CLOUD BASE
ROTATION WITH POTENTIAL TO PRODUCE TORNADOES. THE TORNADO THREAT IS
EXPECTED TO CONTINUE THROUGH THE OVERNIGHT PERIOD AND MAY GRADUALLY
SHIFT NWD WITH TIME.
