Areas affected...portions of far southeastern North Dakota into far
northeast South Dakota and western Minnesota

Concerning...Severe potential...Watch possible

Valid 242349Z - 250115Z

Probability of Watch Issuance...60 percent

SUMMARY...An ongoing MCS may continue downstream of Severe
Thunderstorm Watch 512 into far western MN. Severe gusts will be the
main threat, though a couple of tornadoes or instances of severe
hail are also possible. A downstream WW issuance may be needed if
confidence increases in the current MCS persisting.

DISCUSSION...A cold-pool-driven MCS has organized across central
into southeastern ND, and should continue to propagate southeast
amid a favorable deep-layer shear/buoyancy parameter space. 23Z
mesoanalysis depicts over 2000 J/kg MLCAPE and 40-50 kts of
effective bulk shear (aligned roughly normal to current MCS
leading-line orientation) preceding the MCS downstream of the
ongoing WW into far west-central MN. However, appreciable MLCINH
also exists downstream, so MCS persistence is unclear. However, if
MLCINH proves to be a lesser concern, an MCS may progress into MN
with severe gusts, and a WW issuance would be needed.
