Areas affected...portions of central North Dakota into central South
Dakota
Concerning...Severe Thunderstorm Watch 478...
Valid 280111Z - 280245Z
The severe weather threat for Severe Thunderstorm Watch 478
continues.
SUMMARY...The severe threat continues across Severe Thunderstorm
Watch 478. Severe gusts are the main threat, though a QLCS tornado
remains possible.
DISCUSSION...A mature MCS with a history of several severe gusts
(some of which were measured in the 80-90 mph range per surface
observations) continues across western ND/SD. The most recent significant-severe gusts have occurred within mesovortices across
southwestern ND, where a QLCS tornado also remains possible.
However, 00Z mesoanalysis depicts 0-3 km lapse rates rapidly
decreasing over ND with east extent, but with 6 C/km 0-3 km lapse
rates present over a wider corridor in SD. As such, severe gust
potential (including peak 75-85 mph gusts) will be greatest over
southern ND into northern SD for at least a few more hours.
