Convective trends will be monitored. If intensification occurs, then weather watch issuance may become necessary. DISCUSSION...The latest high-resolution radar imagery from Memphis shows an MCS located from western Tennessee northward into southeast Missouri and southern Illinois. This cluster of strong convection is located along the eastern edge of a pocket of moderate instability. The instability, combined with large-scale ascent associated with a shortwave trough over the mid Mississippi Valley (evident on water-vapor imagery), will provide support for continued convective development over the next few hours. The MCS is forecast to track southeastward across west-central Tennessee into far northeast Mississippi and northern Alabama. As surface temperatures warm and instability increases, the severe threat associated with the MCS could strengthen. Wind damage would be possible, especially along the leading edge of the faster moving bowing line segments. ...Broyles/Edwards.. 08/03/2023 ATTN...WFO...OHX...BMX...HUN...PAH...MEG...LSX...
