Areas affected...northern South Carolina

Concerning...Tornado Watch 129...

Valid 031842Z - 031945Z

The severe weather threat for Tornado Watch 129 continues.

SUMMARY...Greatest short-term threat for tornadoes is expected to
remain across northern South Carolina through.

DISCUSSION...A couple of supercells with persistent strong low-level
mesocyclones and history of tornadoes have crossed into western
South Carolina. These storms are moving east near 30 kt along a
stalled boundary. Effective bulk shear around 45 kt remains
favorable for supercells. Tendency has been for near surface winds
to veer to southwesterly with time which has reduced the size of 0-2
km hodographs in the moist warm sector. This suggests greatest
near-term tornado threat will probably remain with storms moving
east and interacting with the boundary where augmented low-level
shear/vorticity resides.
