Areas affected...eastern ND/SD into northeast NE

Concerning...Severe Thunderstorm Watch 514...515...

Valid 190427Z - 190600Z

The severe weather threat for Severe Thunderstorm Watch 514, 515
continues.

SUMMARY...Isolated strong to severe thunderstorms will continue to
pose a risk for damaging gusts and large hail another couple of
hours.

DISCUSSION...Isolated thunderstorms from southeast ND into eastern
SD and northeast NE will continue to shift southeast within an
instability gradient. Moderate instability and vertical shear will
support strong storms for another couple of hours. With time
convection will encounter a more hostile downstream environment, due
to increasing inhibition and weakening instability with eastward
extent. New watches downstream from WW 514 and 515 are not expected.
