....THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS OVER PARTS OF
THE CENTRAL HIGH PLAINS...

....SUMMARY...
Scattered severe thunderstorms will persist across parts of the
central Plains through tonight. Large hail, severe gusts, and a
tornado or two remain possible.

....Central High Plains...
Scattered severe cells stretch from western NE into northeast CO
where tornadoes and very large hail have been reported. Southeast
surface winds and 60s F dewpoints will maintain an unstable air mass
across this region, and an eventual MCS may materialize from
coagulating outflows from the aforementioned supercells. The 00Z DDC
sounding show steep lapse rates aloft and modest levels of moisture,
enough to sustained an MCS, but not particularly unstable. Midlevel
flow is around 30-35 kt but high level winds are very strong, with
up to 100 kt at 200 mb. This may allow storms to remain somewhat
cellular for a prolonged period, and could limit damaging wind
potential while maximizing hail. As such, severe probabilities have
not been changed much at 01Z in this region. For more information
see MCD 1910.
