Valid 250100Z - 251200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE
NORTHERN PLAINS AND CENTRAL HIGH PLAINS...
...SUMMARY...
Severe thunderstorms will remain possible this evening across
eastern North Dakota/northwest Minnesota, as well as central South
Dakota and western Nebraska, with large hail and damaging winds the
primary hazards.
...Northern Plains/Upper Midwest and central High Plains...
Scattered severe thunderstorms including a few supercells will
continue across central South Dakota into northern Nebraska, and
possibly west-central Nebraska within a zone of 60s F surface
dewpoints and moderate instability ahead of a front and near a
southward-extending pre-frontal trough. Large hail and damaging
winds will remain possible this evening as storms persist
southeastward.
Somewhat richer low-level moisture exists ahead of the front across
north-central/northeast South Dakota into eastern North Dakota where
scattered severe storms continue this evening. 00z observed
soundings from Aberdeen and Bismarck sampled effective shear around
40 kt with 2000-2500 J/kg MLCAPE and steep mid-level lapse rates.
Supercells will remain possible in the short-term, but a modest
degree of upscale growth may occur as storms further cluster and
progress southeastward with continued hail/wind potential at least
through the evening.
...Northern Great Basin/north-central Rockies...
A few stronger storms capable of gusty/potentially severe-caliber
wind gusts will remain a possibility over the next hour or two this
evening, with storm updraft/downdraft intensity expected to diminish
thereafter.
