Mesoscale Discussion 0170

0557 PM CST Thu Feb 16 2023
Areas affected...Far northern Alabama into Middle/Eastern Tennessee
Concerning...Tornado Watch 39...
Valid 162357Z - 170130Z
The severe weather threat for Tornado Watch 39 continues.
SUMMARY...A strong to locally severe storm or two remains possible
in Middle/Eastern Tennessee and possibly northeast Alabama this
evening. Increasingly poor thermodynamics should preclude additional
watch issuance.
DISCUSSION...Convective trends have generally shown a decrease in
storm intensity and organization over the past 1-2 hours. A storm
will persistent mid-level rotation has recently dissipated east of
Nashville. A couple of stronger storms remain in Middle Tennessee.
These storms may maintain some intensity for another hour or two
given marginally warm temperatures (around 70 F) in the Chattanooga
vicinity. Damaging winds and marginally severe hail are the main
threats, though a brief tornado could also occur. Otherwise,
precipitation ahead of the stronger activity combined with drier air
will limit buoyancy as storms move eastward. While a local extension
in time of WW 39 is possible depending on observational trends,
additional watch issuance is not expected this evening.
