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

...SUMMARY...
Scattered severe thunderstorms are expected this evening across
parts of the northern/central High Plains. Isolated very large hail
and significant severe wind gusts are possible in parts of the High
Plains.

...01z Update...

Early-evening water-vapor imagery depicts a well-defined short-wave
trough over the northern Rockies which is quickly advancing into the
High Plains. A substantial complex of storms has evolved ahead of
this feature, and an MCS appears to be maturing over central NE. As
this complex grows upscale, an MCV may evolve over the next few
hours within the larger precip shield north of Broken Bow NE.
Leading edge of this complex is surging east and this convection
should continue propagating east as the LLJ begins to focus toward
the MO Valley. Several other bands of robust convection have also
developed across the central High Plains from portions of western KS
into eastern CO. This activity, too, will propagate east-southeast
this evening with an attendant threat for damaging winds, and
perhaps some very large hail with any supercell structures.
Although, much of this activity has evolved into a squall line, and
damaging winds may become the primary risk. Overall, multiple
clusters of organized convection will progress across the central
Plains this evening toward the lower MO Valley after midnight.
