...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS PRIMARILY ACROSS
THE CENTRAL PLAINS INTO THE LOWER MISSOURI VALLEY...

...SUMMARY...
Isolated large hail and strong-severe outflow gusts remain possible
this evening into tonight primarily across the central Plains into
the lower to mid Missouri Valley.

...01z Update...

Early-evening water-vapor imagery depicts a low-amplitude short-wave
trough ejecting through the ridge into the central High Plains. 1km
flow is beginning to strengthen ahead of this feature, and will do
so markedly later this evening when speeds may exceed 60kt into
southern KS. LLJ should veer into west central MO by the end of the
period. Robust convection is expected to develop along the nose of
the LLJ later this evening, and one or more clusters of storms
should propagate across the central Plains into western MO. Hail and
wind are possible with this activity.
