The severe weather threat for Tornado Watch 80 continues.
SUMMARY...Increasing tornado potential for parts of southwest and
central AL through 1030 pm CDT as warm sector supercells develop
ahead of the convective band.
DISCUSSION...Radar imagery from KMOB shows developing supercells
over Clarke and Marengo Counties as of 840pm CDT. These storms have
recently developed within the warm conveyor belt within an
environment characterized by intense low- to mid-tropospheric wind
fields (per KBMX 88D VAD data) and weak but increasing buoyancy.
The low-level moisture contribution to buoyancy will be the key
factor in the conditionality of tornado potential with these storms.
It appears the northern rim of mid 60s deg F dewpoints is near this
activity. Very strong low-level moisture advection via 50-60 kt 1-2
km southerly flow will act to destabilize the airmass immediately
downstream of these storms. As a result of an increasingly
favorable environment, tornado potential will likely begin to focus
over central AL during the next 2 hours with these warm sector
supercells. A strong tornado is possible, especially if updrafts
can further intensify/mature.
