...New UPDATE...

.UPDATE...
Issued at 207 PM CDT Thu Apr 18 2024

At mid afternoon, skies remained sunny across Middle Tennessee. We
are watching the start of a few cells just west of the Tennessee
River near Savannah. Latest HRRR doesn't do much with these 
initial cells, but that may change if the cells do get 
established. Main focus is on well developed storms back over 
western Mississippi. We are still looking for this scattered storm
activity to spread northeast into our area later on with peak
coverage between 7 PM and 10 PM. Short range models continue to 
show good cape with a narrow axis of 2500 J/kg pivoting into our 
southwest counties toward 7 PM. Shear still looks marginal at 
best. So, we continue to expect a few instances of localized gusty
winds and marginal sever severe hail with the early evening 
scattered storms. Later storms coming in from the west northwest 
after 10 PM will have better shear, so gusty winds and maybe a 
QLCS spinup tornado cannot be ruled out as the storms approach. 
But the late storms will weaken considerably as they push into our
area and especially toward I-65.
