...New UPDATE...

.UPDATE...
Issued at 842 PM CDT Wed Apr 17 2024

All is quiet across Middle Tennessee this evening with only some
high clouds in the area. It will be another mild night with lows
in the upper 50s to mid 60s. The area will be dry through the
early afternoon hours on Thursday. Models show the potential for
scattered showers and storms to develop around mid to late 
afternoon west of I-65 and lift northeastward. The atmosphere will
be amply unstable with surface base CAPE values exceeding 2000
J/kg. Effective bulk shear values will be moderate with values
between 20-30 kts. With this said, some storms may reach the 
severe threshold with damaging winds and large hail as the primary
threats. Tornadoes are not expected with 0-1 and 0-3 SRH around 
or below 100 m2/s2. 

A line of storms ahead of a cold front will approach the area
after the late afternoon round. The severity of this round of
storms will be somewhat dependent on how widespread the first 
wave is. If the afternoon wave is somewhat isolated in coverage, 
then the second wave will pose more of a severe threat as it 
enters from the northwest. Regardless, the line of storms is 
expected to lose some intensity as it continues to move eastward 
through the remainder of the overnight hours. Damaging winds will
be the primary threat with the line of storms. Again, low level 
shear is on the lower side, so tornadoes are not expected with
this wave.
