Areas affected...Northeast SD...Southeast ND...Northern MN

Concerning...Severe potential...Watch possible

Valid 300703Z - 300900Z

Probability of Watch Issuance...60 percent

SUMMARY...Elevated thunderstorms capable of large hail may develop
across the region over the next few hours. A watch may be needed
over portions of the region to cover this severe potential.

DISCUSSION...A arcing band of elevated thunderstorms currently
extends from about 15 miles north of HON (in northeast SD)
northeastward to about 20-25 miles northeast of VVV in west-central
MN. This band has been moving gradually northward while also
developing a bit farther eastward into more of central MN. The
downstream air mass across southeast ND and northern MN is
characterized by moderate to strong buoyancy, with MUCAPE ranging
from 1000 over southeast SD to 3000 over northern MN on recent
mesoanalysis. Moderate vertical shear is also in place, with
effective bulk shear around 30 to 40 kt.

Given these environmental conditions, some severe thunderstorms are
possible as the ongoing elevated band of storms moves northward into
the region. Additional in-situ development is also possible,
particularly across northern MN. Primary severe threat would be
large hail and a watch may be needed over portions of the region to
cover this potential.
