The severe weather threat for Tornado Watch 572 continues.

SUMMARY…Tornado risk has diminished some across the watch, while
risk for damaging winds and marginal hail continues. Wind risk is
expected to spread eastward out of the watch over the next couple of
hours, with new WW expected.

DISCUSSION…Latest radar loop shows that earlier, supercell storms
have congealed into an eastward-moving storm cluster, with a rather
strong mesolow moving out of Cheyenne and into Rawlins County in
Kansas. At this time, it appears that damaging wind risk will not
only continue within WW 572, but will also spread eastward,
downstream of the watch with time. Given the very moist boundary
layer/unstable airmass in place across the central Plains, risk will
likely warrant new watch issuance, possibly including southeast
Nebraska and northeast Kansas.
