...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE
CENTRAL/NORTHERN 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...
An increasingly prominent mid/upper-level trough will overspread the
region with appreciable height falls as far south as Nebraska and
Iowa. A surface low is forecast to deepen over the Dakotas, along an
advancing front. The influences of early day convection across
eastern portions of Nebraska/Kansas are still expected be modulating
factors and points 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 the upstream weak
cold front.

The most surface-based severe-favorable setup should materialize
across central/eastern Nebraska into Monday late afternoon/early
evening, and to a lesser extent northwestward into western/central
parts of South Dakota. Moderate buoyancy and seasonally strong
deep-layer shear could support potentially intense supercells,
especially across central Nebraska. This includes a risk for all
severe hazards regionally. Some upscale growth is possible into the
evening as storms spread eastward across Nebraska, with a continued
severe risk potentially reaching parts of Iowa and possibly
Minnesota Monday night.

...Southeast States...
Locally severe storms capable of wind damage may occur mainly Monday
afternoon through early evening within a moderately unstable
environment along and south of the southward-sagging front and a
related surface wave. It still seems that this risk is most probable
across southern South Carolina and southern/eastern Georgia into
northern Florida and possibly southeast Alabama.
