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

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

....Synopsis...

An upper shortwave trough over the southern/central Plains early
Thursday will weaken as it lifts northeast toward the Great Lakes
and southern Ontario by early Friday. A moist boundary-layer with
surface dewpoints generally in the low/mid 60s will extend from
eastern portions of the southern Plains through the Lower MO and Mid
MS Valleys, with mid 50s to low 60s F dewpoints further north toward
the Great Lakes. A surface low will develop northeast from IA to
southern Ontario through the period while a cold front migrates
southeast across the northern/central Plains and Upper Midwest.

Widespread showers and thunderstorms will likely be ongoing Thursday
morning across eastern portions of the southern Plains and Ozark
Plateau, northward from eastern NE/IA into WI/MI. While a moist
boundary-layer will be in place amid 35-50 kt west/southwesterly 0-6
km shear, poor low/midlevel lapse rates and weak surface heating
will preclude much destabilization. This should limit severe
potential on Thursday.
