....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe thunderstorms are not forecast on Thursday.

....Synopsis...

An upper low will persist over the northern Plains while an
attendant shortwave trough moves across the central Plains toward
the Mid/Lower MO Valley vicinity on Thursday. At the surface, weak
low pressure will be in place across eastern portions of the Plains
into the MO/MS Valley vicinity. Upper 50s to mid-60s F dewpoints
will persist across the eastern Plains to the Ozarks and northern
into parts of the Upper Midwest. This will support pockets of weak
to moderate destabilization, particularly across eastern OK/KS into
the Ozarks, and northward into IA. Scattered diurnal thunderstorm
activity will develop within this modest moisture and instability.
However, nebulous forcing for ascent, weak vertical shear, and
generally poor lapse rates will preclude organized severe potential.
