Tornado Potential Increasing for South Central Alabama

Increasing dynamics supportive of tornadoes are located over parts of South Central Alabama tonight and the storms moving into and through this corridor have an enhanced potential to produce tornadoes. We want all of our friends in the tornado watch to be vigilant, especially in the US-80 and I-85 Corrdiors.

Areas affected…Portions of south-central Alabama

Concerning…Tornado Watch 89…

Valid 270047Z – 270215Z

The severe weather threat for Tornado Watch 89 continues.

SUMMARY…A locally favorable corridor for supercell tornadoes may
be developing over portions of south-central AL (near and just south
of Montgomery) during the next couple hours.

DISCUSSION…Latest surface observations and radar/satellite imagery
indicate a remnant outflow boundary extending east/southeastward
from near/south of Montgomery AL into southeast AL. Through this
corridor, dewpoints remain in the middle/upper 60s and surface winds
are relatively backed. While somewhat removed from this area, the
LIX 00Z observed sounding shows deep boundary-layer moisture beneath
steep midlevel lapse rates (supporting a deep effective inflow
layer), and this should be somewhat representative of the
environment spreading into south-central AL. In addition, regional
VWPs show a modest increase in low-level flow, and further
strengthening should yield larger/clockwise-turning low-level
hodographs with time. If the supercell cluster in Wilcox
County/southern Dallas County continues eastward along the outflow
boundary, the aforementioned environment could favor increasing
tornado potential with this storm (or additional storms that can
develop into this environment) during the next couple hours.
