...NO SEVERE THUNDERSTORM AREAS FORECAST...



...SUMMARY...

Thunderstorms are possible across portions of the the Middle

Mississippi Valley and northern High Plains, though organized severe

storms are not expected.



...Synopsis and Discussion...

An amplifying/intensifying midlevel trough will track southeastward

from the northern Plains toward the Lower Ohio Valley through the

period. A related surface cyclone will advance eastward from the

central Plains to the Lower Great Lakes, while a trailing cold front

moves eastward across the Lower/Middle Mississippi Valley. Ahead of

the trough and surface cyclone, low-level moisture will be limited,

though cold midlevel temperatures/steep midlevel lapse rates will

result in weak instability. Given strengthening DCVA and low-level

warm advection, isolated to widely scattered thunderstorms will be

possible, with a focus over the Middle Mississippi Valley. Organized

severe thunderstorms are not expected at this time. 



Farther west, steep deep-layer lapse rates will contribute to weak

buoyancy over the northern High Plains, where ascent in the

left-exit region of an upper jet will promote isolated

thunderstorms.
