....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR PORTIONS OF
KANSAS AND THE CENTRAL TO NORTHERN HIGH PLAINS...

....SUMMARY...
A few instances of severe wind/hail remain possible across parts of
Kansas and the central/northern High Plains this evening.

....Synopsis...
Mid-level troughing persists across the western U.S. as an upper
ridge remains in place over the central CONUS. A mid-level trough
continues to progress across the Northeast, albeit with diminishing
buoyancy. Thunderstorm clusters will persist for many areas west of
the Rockies given large-scale lift and adequate buoyancy. Storms
east of the Rockies are thriving primarily on rich low-level
moisture and residual buoyancy from strong diurnal heating. A chance
for an additional instance of severe wind or hail remain with storms
across Kansas, where buoyancy is strongest in the central/southern
Plains. Storms are strengthening along and to the east of the
central/northern Rockies where both buoyancy and deep-layer are
maximized (i.e. 1000-2000 J/kg MLCAPE and 30-50 kts in place), and
it is here where isolated severe wind and hail may still be
observed.
