Areas affected...Northern High Plains
Concerning...Severe Thunderstorm Watch 179...
Valid 280230Z - 280400Z
The severe weather threat for Severe Thunderstorm Watch 179
continues.
SUMMARY...Severe threat continues with thunderstorms this evening.
DISCUSSION...Low-level convergence is gradually shifting east this
evening as the primary surface cyclone is now into northeast CO.
Even so, the main boundary currently arcs along the western fringe
of ww179 from Carter County MT-western Pennington County SD. Several longer-lived storms with large hail are progressing across southeast
MT toward northwest SD, while more liner activity appears to be
evolving along the wind shift over the western Black Hills. Hail
remains the primary concern with this activity, though the potential
for gusty winds with line segments is of some concern. Severe threat
continues.
