.DISCUSSION...
Issued at 125 PM CDT Mon Jun 8 2026

A few showers and thunderstorms continue to develop and quickly
weaken in west central MN this afternoon. They are all forming on
the warm side of a weak frontal boundary/sfc trough that is draped
from Milbank to Mitchell. There is a marginal risk for severe storms
in this area with increasing shear after 21z. 1 inch hail will be
the main threat from any stronger storms.

All attention is really focused on the impending severe weather
Tuesday afternoon through Wednesday morning as a stronger cold front
moves through from west to east. The sfc front will be aided by
ample shortwave activity ejecting out of the broad upper trough over
the Rockies with an increasing jet in the evening. There is an
enhanced risk (3 of 5) over most of the region on Tuesday with all
hazards possible, including an isolated tornado or two, especially
near the SD/ND border. However, the set up seems most favorable for
a line or MCS with very strong winds over 70 mph.

Temperatures cool markedly behind Tuesday`s system with highs
Wednesday through early next week in the 70s to lower 80s.
