...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE
NORTHERN/CENTRAL PLAINS...

...SUMMARY...
Severe thunderstorms will be possible on Monday across the
northern/central Plains including parts of Nebraska and South
Dakota.

...Northern/central Plains and Upper Midwest...
A mid/upper-level trough is expected to overspread the region with
appreciable height falls, particularly by early summertime
standards, as far south as Nebraska and Iowa. A surface low is
forecast to deepen over the Dakotas, along a surface trough. The
influences of early day convection will probably be a modulating
factor and point of uncertainty spatially, but a warm front should
effectively transition north-northeastward during the day, with very
rich low-level moisture in its wake to the east of a weak cold
front. The most surface-based severe-favorable setup may materialize
across central/eastern Nebraska into Monday late afternoon/early
evening, and possibly into parts of South Dakota. Seasonally strong
deep-layer shear will support potentially intense supercells, with a
risk for all severe hazards. Some upscale growth is possible into
the evening as storms spread eastward, with a continued severe risk
potentially reaching parts of Minnesota and Iowa Monday night.

...Southeast States...
Some strong to locally severe storms capable of wind damage may
occur Monday afternoon through early evening within a moderately
unstable environment along and south of the southward-sagging front.
Current thinking is that this risk is most probable across southern
South Carolina and southern/eastern Georgia into northern Florida.
