Valid 190100Z - 191200Z

....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
SOUTH DAKOTA...NEBRASKA...WESTERN/CENTRAL IOWA...AND SOUTHWEST
MINNESOTA...

....SUMMARY...
Isolated severe thunderstorms are possible the remainder of the
evening into the overnight hours across parts of South Dakota,
Nebraska, southwest Minnesota and western/central Iowa.

....01z Update...

The Marginal risk (Level 1 of 5) has been removed along much of the
dryline from KS into western OK/northwest TX. Isolated thunderstorms
will continue near the NE/KS border, shifting east/northeast through
the remainder of the evening, but additional thunderstorm
development is unexpected further south. Thunderstorms over eastern
WY into western SD/NE will percolate eastward, and some additional
development is expected overnight with this activity, as well as an
increase in coverage with the south-central NE cluster. As this
convection shifts east/northeast overnight toward eastern SD,
southwest MN and western/central IA, sporadic strong gusts and hail
will be possible.
