Areas affected...Southern middle TN into north AL

Concerning...Severe potential...Watch possible

Valid 100559Z - 100730Z

Probability of Watch Issuance...40 percent

SUMMARY...Some damaging-wind threat will persist overnight as storms
spread eastward. Downstream watch issuance is possible if there is
any uptick in storm intensity/organization.

DISCUSSION...A small bowing segment has evolved within a larger
thunderstorm cluster across western TN. The downstream environment
remains favorable for organized convection, with rather strong
low/midlevel flow and favorable deep-layer shear noted on regional
VWPs, along with moderate buoyancy. A low-level temperature
inversion and a related tendency for convection to be somewhat
elevated has limited the damaging-wind threat thus far, and may
continue to do so as storms generally stay north of an outflow
boundary across central AL. However, any uptick in intensity with
the bowing segment and/or the trailing convection to the southwest
may be accompanied by an increasing risk for damaging gusts
overnight. Short-term trends will continue to be monitored for
possible watch issuance.
