Areas affected...North Georgia

Concerning...Severe potential...Watch unlikely

Valid 222008Z - 222145Z

Probability of Watch Issuance...20 percent

SUMMARY...Mini-supercells with a threat of a brief tornado or two
will continue this afternoon. Limited coverage and magnitude of the
threat makes watch issuance unlikely.

DISCUSSION...Mini-supercell development has recently taken place
across north Georgia, just to the northwest of Atlanta. While
low-level flow is not quite as strong as areas further west, a very
moist boundary layer, modest instability, and favorably veering
low-level wind profiles will continue to support the development of
small rotating cells through the afternoon. The greatest threat will
likely be near and just north of a diffuse surface boundary across
north Georgia, where surface winds are backed to more of an
east-southeasterly direction. A tornado or two will be possible as
these small cells interact with the surface boundary.
