Concerning...Tornado Watch 62...
Valid 250245Z - 250345Z
The severe weather threat for Tornado Watch 62 continues.
SUMMARY...If current storm-scale and near-storm environmental trends
continue, the tornado watch can likely be cancelled within the next
hour prior to watch expiration time, which is currently scheduled
for 1am EDT/12am CDT.
DISCUSSION...Radar imagery during the past hour has shown
diminishing echo tops and storm weakening across northern AL and
into adjacent parts of TN/GA. Surface observations over northeast
AL to the south of the convective cluster have shown a gradual
veering in flow. The 00z Atlanta observed sounding showed less than
300 J/kg MLCAPE and buoyancy has likely lessened owing to cooling of
the near-surface layer. Given the aforementioned trends/factors,
current thinking is the potential for severe will continue to
lessen, particularly the tornado risk. As a result, the watch may
be cancelled early if trends continue.
