...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.
