Latest Mesoscale Discussion from the SPC:
The severe weather threat for Tornado Watch 4 continues.
SUMMARY… An isolated severe threat may persist for a couple more hours early this morning before gradually diminishing. A couple of tornadoes and occasional strong/gusty winds should be the main threats.
DISCUSSION…Recent radar imagery shows a broken line of storms extending northeast to southwest across northwestern GA and central AL. The low-level flow across this region should have a tendency to gradually veer to a more southwesterly direction and slowly weaken as the strongest portion of a low-level jet advances into the Carolinas over the next few hours. Even so, there should still be enough veering/strengthening of the wind field in low levels (reference 06Z BMX sounding) to support updraft rotation. A couple of tornadoes will remain possible in the short term with storms advancing northeastward within the broken line. Isolated strong/gusty winds producing occasional damage may also occur with any cell that can acquire a small bowing structure. Current expectations are for this isolated severe threat to gradually diminish later this morning as the low-level flow becomes increasingly parallel to the ongoing convection, which should reduce 0-1 km SRH. The marginal thermodynamic environment across west-central into northern GA should also limit the eastward extent of any meaningful severe risk.
