Are these MDs the SPC have been doing on individual super cells relatively new? I feel like I’ve only seen them in the past year or two.
SUMMARY...Based on recent radar and environmental data, a strong to
potentially intense tornado with potential peak winds of 110 to 155
mph (EF1-EF3) is likely ongoing and tracking towards Alexandria, LA.
DISCUSSION...Recent radar signatures from KPOE as of 1832z reveal a
long track tornadic supercell characterized by a 0.5 degree
rotational velocity between 61 and 70 kt. A tornadic debris
signature has also been noted on recent radar scans. These
signatures are occurring in an environment characterized by STP
between 4 and 5. Previous signatures within similar environments
produced tornado-damage-estimated wind speeds from 110 to 155 mph
and confidence is high for likely strong to potentially intense
tornado. A tornado is ongoing and may continue based on the
rotational velocity continuity and the storm moving within a
favorable downstream environment.
