Mesoscale Discussion — New Watch Possible Within the Next Few Hours
SUMMARY… A gradual increase in convection is expected as the evening progresses, with it a risk of wind and perhaps a tornado or two. A new watch may be warranted.
DISCUSSION… Boundary-layer air mass is expected to gradually respond across the lower MS Valley due to an approaching short-wave trough over Texas. Low-level flow should become a bit more convergent which should encourage additional convective development and perhaps more robust updrafts. Over the last hour or so, a fair number of thunderstorms have matured from south-central LA into east-central MS. Several supercells are observed along this corridor and an upward tick in coverage/intensity may be noted as the evening progresses. Overall, scattered strong/severe thunderstorms should become more noteworthy prior to frontal passage. A new watch may be warranted to account for this risk.
Probability of Watch Issuance…60 percent
