Areas affected...South Dakota...North Dakota

Concerning...Severe Thunderstorm Watch 422...

Valid 030340Z - 030545Z

The severe weather threat for Severe Thunderstorm Watch 422
continues.

SUMMARY...A threat for wind damage and hail appears likely to
continue for several more hours across WW 422. However, the threat
should beco*e more isolated after midnight, and additional weather
watch issuance to the southeast of the ongoing watch, appears
unlikely.

DISCUSSION...Latest mosaic radar imagery shows a line of strong to
severe storms located from northwest South Dakota into central North
Dakota. A second line of strong storms is located to the east of
Rapid City. These two lines could persist for several more hours.
The corridor with the greatest severe potential could be across
northwestern and north-central South Dakota, along the north edge of
a corridor of stronger instability. The RAP forecast sounding at
Mobridge, South Dakota at 06Z has 0-6 km shear near 45 knots, with a
700-500 mb lapse rates around 7.5 C/km. This should be sufficient to
continue a severe threat late this evening into the early overnight
period. Wind damage will be the greatest threat, along the leading
edge of the stronger downdrafts. Hail could also occur in the
stronger updraft cores.
