...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF

EASTERN NORTH AND SOUTH DAKOTA AND WESTERN MINNESOTA...



...SUMMARY...

Thunderstorms with large hail, severe wind gusts, and a couple of of

tornadoes will be possible this evening in parts of the northern

Plains. A few marginally severe wind gusts may occur across parts of

Kansas and northern Oklahoma.



... Eastern North and South Dakota and Western Minnesota ...



Severe thunderstorms continue this evening across portions of

eastern South Dakota, particularly across Tornado Watch #271. The

environment across the watch remains unstable with MLCAPE values

ranging from 2000 J/kg across southern South Dakota to around 1000

J/kg across northern South Dakota. Deep-layer shear will remain

sufficient for thunderstorm organization, including supercells into

the overnight hours. Low-level wind fields are expected to improve

over the next 2-3 hours, which may yield an increased potential for

tornadoes during this period.



The severe threat should continue slowly eastward into portion of

far western Minnesota during the overnight hours.
