....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS THE
CENTRAL AND SOUTHERN HIGH PLAINS...

....SUMMARY...
Isolated severe thunderstorms are possible across the central and
southern High Plains on Thursday.

....Synopsis and Discussion...
Upper pattern is expected to feature ridging across the central
CONUS, flanked on each side by closed lows. This general pattern is
expected to remain unchanged throughout the period, even as the
western CONUS low gradually shifts southward across OR and the
eastern CONUS low progresses eastward across ME.

Severe thunderstorm potential will be focused across the central and
southern High Plains where another round of afternoon thunderstorms
is likely. Upper 50s dewpoints are anticipated along and east of the
lee trough, with thunderstorms expected to persist as they move off
the high terrain into the lower elevations or as develop along the
lee trough. Vertical shear will not be strong, but should still be
sufficient for some storm organization amid the moderate buoyancy
expected to be in place. Damaging gusts will be the primary severe
hazards, but isolated hail and a tornado or two are also possible.
