Valid 190100Z - 191200Z
...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
SOUTH DAKOTA...NEBRASKA...WESTERN/CENTRAL IOWA...AND SOUTHWEST
MINNESOTA...
CORRECTED FOR VALID TIME ERROR
...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.
