Mesoscale Discussion 0413

0742 PM CDT Sun Apr 19 2020

Areas affected...Portions of Southern Mississippi

Concerning...Tornado Watch 123...

Valid 200042Z - 200115Z

The severe weather threat for Tornado Watch 123 continues.

SUMMARY...Based on recent radar and environmental data, a strong to
potentially violent tornado with potential peak winds of 120 to 170
mph EF3+ is likely ongoing.

DISCUSSION...Recent radar signatures from KLIX as of 838 PM EDT
reveal an intense supercell characterized by a 0.5 degree rotational
velocity between 60 and 69 kt. A tornadic debris signature has also
been noted on recent radar scans. These signatures are occurring in
an environment characterized by STP between 3 and 4. Previous
signatures within similar environments produced
tornado-damage-estimated wind speeds from 120 to 170 mph and
confidence is high for a strong to potentially violent tornado. A
potential long-track tornado is ongoing and may continue based on
the rotational velocity duration and the storm moving within a
favorable downstream environment.
