Concerning...Severe Thunderstorm Watch 608...

Valid 070133Z - 070230Z

The severe weather threat for Severe Thunderstorm Watch 608
continues.

SUMMARY...Severe threat continues within WW608.

DISCUSSION...Two clusters of thunderstorms are ongoing across
portions of southeastern Montana and northeastern Wyoming. Storms
have produced severe gusts up to 68 mph and hail up to 1 inch in the
last couple of hours. The greatest near term threat appears to be
across northeastern Wyoming into western South Dakota. Lightning
activity with this cluster of storms has been more frequent. With
eastward extent, these storms will encounter a capped airmass across
western South Dakota, with MLCAPE 500-1000 J/kg. Enhanced mid-level
flow across this region is supporting 40-45 kts of deep layer shear,
which may aid in maintaining organized storms in the near term. The
00z RAOB from Rapid City shows MLCIN to be generally weak amid steep
low to mid-level lapse rates. Potential for strong to severe winds
and large hail will continue across Wyoming into western South
Dakota in the near term.
