The severe weather threat for Severe Thunderstorm Watch 298
SUMMARY...The severe weather threat continues across much of WW 298,
with damaging winds being the primary risk as storms develop and
spread from west to east. The counties across the western extent of
this watch can be canceled, as the air mass has stabilized in the
wake of the ongoing cluster of storms.
DISCUSSION...At 2045Z, mosaic radar imagery indicated the main
cluster of storms that had moved from AL into GA was now located
from Cherokee, Cobb, and Fulton counties southward to Monroe County
GA, while additional storms had developed farther to the south and
east. A midlevel impulse, likely attendant to the main cluster of
storms, will move across the remainder of WW 298 late this afternoon
into the early evening, with sufficient instability and strong bulk
shear favoring additional strong to severe storms.
Meanwhile, objective analyses indicated convective overturning has
stabilized the air mass in the wake of the ongoing cluster of storms
in central/northern GA, suggesting counties in the wake of this main
cluster should be able to be canceled early.
