...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected on Saturday.

...Synopsis...

A weak mid/upper shortwave impulse will spread east from the
central/southern Plains to the Mid/Lower MS Valley on Saturday.
Modest boundary layer moisture (increasing near the Gulf Coast) and
cool temperatures aloft (around -10 to -12 C at 500 mb) will support
sufficient instability for widely scattered showers and
thunderstorms from OK/TX toward the Lower MS Valley. Overall severe
thunderstorm potential will remain limited by generally weak flow
and lack of stronger surface cyclogenesis. Additional thunderstorms
are possible across portions of the Great Basin as an upper trough
deepens across the Pacific Northwest and northern Great Basin at the
same time as a southern stream upper trough approaches the southern
CA and Baja coasts. Severe thunderstorms are not expected with this
activity.
