   Mesoscale Discussion 0036
   NWS Storm Prediction Center Norman OK
   0158 AM CST Tue Jan 26 2021

   Areas affected...Portions of central AL and
   west-central/northwestern GA

   Concerning...Tornado Watch 4...

   Valid 260758Z - 260930Z

   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
   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
   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.
