Mesoscale Discussion 0221
NWS Storm Prediction Center Norman OK
0430 AM CDT Sun Mar 16 2025
Areas affected...Southeast Georgia to south central North Carolina
Concerning...Severe potential...Watch likely
Valid 160930Z - 161030Z
Probability of Watch Issuance...80 percent
SUMMARY...The potential for occasional wind damage and a couple of
tornadoes with embedded circulations will spread east of the current
watches. A new tornado watch will likely be needed by 10z from
southeast Georgia across South Carolina into south central North
Carolina.
DISCUSSION...A persistent QLCS continues to move eastward toward
east central GA and will reach the edge of tornado watch #50 close
to 10z. Echo depth and flash rates have decreased some over the
past hour, which could be a reflection of the storms getting too far
ahead of the destabilization, and weakening forcing for ascent with
time. Still, a 70 kt low-level jet and surface temperatures near 70
with low-mid 60s dewpoints suggest that some rejuvenation of the
convection will be possible. Given the strong vertical shear
profiles, any persistent storms would pose some threat for damaging
winds and a couple of tornadoes. The MD area is being considered
for a new tornado watch by about 10z.
