Hail & Wind Threat Continues Across Severe Thunderstorm Watch Area in Northeastern Parts of Central Alabama

Here is the text from the latest Mesoscale Discussion:

SUMMARY… Thunderstorms across northeast Alabama and northwest Georgia will continue to pose a risk for severe hail and wind through the evening hours.

DISCUSSION… Discrete and embedded supercells continue to traverse eastward across northeast AL in the vicinity of a surface low and along a weak trough axis. Several severe hail reports have been noted with this activity, and and an environment featuring 1000-1500 J/kg MLCAPE along with 50-60 knots of effective bulk shear will remain supportive of a severe hail threat for the next couple of hours. Deep-layer shear vectors oriented along the trough axis may favor eventual upscale growth that could limit the hail threat while augmenting the potential for damaging winds, though the exact evolution is uncertain.

However, the environment remains somewhat spatially limited with eastward extent due to cooler air to the north of a weak warm front, and a residual cold pool in place across central GA. Modest warm air advection in the 925-850 mb layer across northwest GA may allow for some eastward expansion of the viable warm sector, but the general expectation is for storms to gradually weaken as they move into north-central GA later this evening.
