THE SEVERE WEATHER THREAT FOR TORNADO WATCH 303 CONTINUES.
SUMMARY...SEVERAL ONGOING SEVERE STORMS ARE MOVING INTO AN
INCREASINGLY FAVORABLE ENVIRONMENT FOR TORNADOES ACROSS NORTHERN
MISSISSIPPI.
DISCUSSION...A COUPLE SEMI-DISCRETE SUPERCELLS ARE TRACKING EASTWARD
ACROSS PARTS OF NORTHWEST/WEST-CENTRAL MS. AHEAD OF THESE STORMS, A
35-KT LOW-LEVEL JET (SAMPLED BY AREA VWPS) IS CONTRIBUTING TO AMPLE
LOW-LEVEL CLOCKWISE HODOGRAPH CURVATURE WITH AROUND 200 M2/S2
EFFECTIVE SRH. GIVEN WARM/MOIST SURFACE-BASED INFLOW AND THIS

HAIL AND LOCALLY DAMAGING WINDS WILL ALSO BE A CONCERN.
