Areas affected...Eastern Montana into far western North Dakota
Concerning...Severe Thunderstorm Watch 283...
Valid 070606Z - 070800Z
The severe weather threat for Severe Thunderstorm Watch 283
continues.
SUMMARY...Large hail and isolated severe gusts will remain possible
into the overnight in eastern Montana and far western North Dakota.
DISCUSSION...With very strong shear (70-80 kt effective in eastern
Montana), storms in WW 283 have generally remained cellular. The
environment will likely continue to support this storm mode, though
small clusters may yet develop. Steep mid-level lapse rates sampled
on this evenings GGW sounding will promote some risk of large hail.
The threat for severe wind gusts is less clear given the
post-frontal nature of the storms. The severe wind risk will be
greater if storms develop along/near the cold front.
