NWS Storm Prediction Center Norman OK
0651 PM CDT Sun May 02 2021
Areas affected...Central Mississippi
Concerning...Tornado Watch 125...
Valid 022351Z - 030045Z
The severe weather threat for Tornado Watch 125 continues.
SUMMARY...Supercells with a history of tornadoes will likely persist
through early evening where a corridor of greater tornado risk
appears likely this evening.
DISCUSSION...Several small supercells along and west of I-55 have
produced confirmed tornadoes over the last 90 minutes. KDGX analysis
shows several low-level mesocyclones with VROTs of 40-50 kts and a
considerable TDS near Yazoo City, MS. SPC mesoanalysis and regional
VWPS show strong veering wind profiles with 200-300 m2/s2 ESRH ahead
of the ongoing storms to near the warm front across north-central
Mississippi. A corridor of greater tornado potential is likely
evolving. The potential exists for several additional tornadoes,
(possibly significant) to develop and track northeastward to the
warm front over the next 1 to 3 hours.
