Areas affected...parts of central and eastern South Dakota

Concerning...Severe Thunderstorm Watch 366...

Valid 240418Z - 240615Z

The severe weather threat for Severe Thunderstorm Watch 366
continues.

SUMMARY...Isolated severe potential ongoing across WW 366 should
become a bit more widespread, as an organized band of storms
crossing western South Dakota moves eastward/into WW 366.

DISCUSSION...Latest radar loop shows a west-to-east band of
strong/locally severe storms moving northward across central South
Dakota/western portions of WW 366.  Hail and locally damaging winds
remain possible with the strongest cells.

Meanwhile, a more organized/bowing band of storms is evolving across
western South Dakota, and is moving rather quickly eastward.  This
band will impinge on northwestern portions of WW 366 over the next
hour, with some increase in damaging wind risk expected.=20=20

Finally, storms moving northward across north-central/northeastern
Nebraska will move into southern portions of WW 366, accompanied by
local hail/wind risk.  Overall, severe-weather potential will likely
persist across the watch over the next several hours, given the
amply unstable airmass in place and persistent low-level warm
advection.
