I've never seen SPC do a mesoscale discussion like this:
Mesoscale Discussion 0150
NWS Storm Prediction Center Norman OK
0251 PM CST Sun Mar 03 2019
Areas affected...central GA
Concerning...Tornado Watch 8...
Valid 032051Z - 032115Z
The severe weather threat for Tornado Watch 8 continues.
SUMMARY...Tornadic storms with potential tornadic wind speeds
100-140mph are possible with the Twiggs County supercell.
DISCUSSION...KFFC radar imagery indicates rotational velocity values
between 45-60 kt with an environment supportive of tornadic
supercells. Experimental tornado damage intensity guidance is
suggestive of wind speeds between 100-140mph. Downstream of this
storm, expecting little to no storm-scale interference in the near
term in a strong low-level shear environment. As other storms over
south-central GA move north into the warm frontal zone over central
GA, the tornado potential will probably increase.
