Areas affected...Northeastern SD...southwestern MN...and far
southeastern ND

Concerning...Severe potential...Watch unlikely=20

Valid 311911Z - 312045Z

Probability of Watch Issuance...5 percent

SUMMARY...A couple instances of marginally severe hail and locally
damaging downbursts could persist for the next couple hours.

DISCUSSION...Latest radar data from ABR shows some recent
intensification of a storm cluster moving northeastward in
northeastern SD this afternoon -- ahead of a remnant MCV. A 60 mph
gust was recently observed with this activity. VWP data indicates a
modest enhancement of low/mid-level flow accompanying the remnant
MCV (around 30 kt of 0-6 km shear and a veering wind profile). This
wind profile, combined with a diurnally destabilizing air mass
beneath modestly steep midlevel lapse rates, could favor a couple
instances of marginally severe hail and localized downbursts on an
isolated basis this afternoon. The overall severe threat should
remain mostly confined along/immediately ahead of the remnant MCV.
