Severe WX Severe Threat 25 March 2021

Mesoscale Discussion 0268
NWS Storm Prediction Center Norman OK
1026 PM CDT Thu Mar 25 2021

Areas affected...parts of west-central GA

Concerning...Tornado Watch 52...

Valid 260326Z - 260430Z

The severe weather threat for Tornado Watch 52 continues.

SUMMARY...Tornado potential will maximize near the GA/AL border and
eventually spread into the greater Atlanta exurbia through 1230 am
EDT. It is uncertain how far east the higher probabilities for a
tornado will eventually develop due to increasingly marginal
low-level moisture with east extent.

DISCUSSION...Surface analysis indicates mid 60s deg F dewpoints
straddling the GA/AL border in west-central GA to the east of a
supercell with a history of producing tornadoes (likely strong) over
east-central AL. The latest RAP/NAM indicate lowest 100 mb mean
mixing ratios increasing into the 13-14 g/kg range over the next
hour with MLCAPE increasing from 750 J/kg to 1000-1200 J/kg. The
KFFC VAD showed 500 m2/s2 0-1km SRH within the moist/sufficiently
unstable airmass. Current thinking is the increasingly rich
low-level moisture (dewpoints rising from 64-65 to 66) may enable a
greater risk for a tornado over the next hour or so.

Looks like that storm on the state line is going to be one to watch for awhile
 
Storm near Cave Spring that just crossed into GA is rotating too. Could be interesting couple hours.
