Areas affected...Northeast Minnesota

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

Valid 122300Z - 130000Z

Probability of Watch Issuance...20 percent

SUMMARY...A small window for large hail, wind damage and possibly a
brief tornado, before storms cross over into the cool air and
weaken.

DISCUSSION...A small cluster of storms has intensified gradually
near the surface triple point to the northwest of Duluth. This
cluster is located along the northwest edge of the remaining
warm/moist sector, and immediately west of slow-moving lake breeze.=20
There will be a narrow window where the environment will support
supercells with a low risk of all hazards, but the threat will be
constrained to large hail once the storm becomes elevated to the
cool side of the lake breeze. Given the small area in time and
space, a watch does not appear necessary.
