For the week of 11 June – 15 June, our distinguished NWS guests are Tim Tinsley (NWS WFO Brownsville, TX), Michael Dutter (NWS WFO Marquette, MI), Ty Judd (NWS WFO Norman, OK), Steve Nelson (NWS WFO Peachtree City, GA), Randy Skov (NWS CWSU Atlanta, GA), and Jeff Garmon (NWS WFO Mobile, AL).

Today, we are focusing on two areas: one is associated with the ongoing mesoscale convective system in the lower-middle Mississippi Valley; the other is in the Southern Plains, where strong heating may be able to overcome a substantial cap.  The former environment is characterized by strong instability, weak low and deep-layer shear, and a weak cap.  The latter environment is characterized by strong to extreme instability, weak deep-layer shear, and a formidable capping inversion.  The plan is to start two groups of forecasters (2 in each group) in the eastern target, and one group in the western target.  The initial CWAs will be Memphis (for strongest convection), Huntsville (for LMA considerations), and Tulsa (for convective initiation considerations).
