   NWS Storm Prediction Center Norman OK
   0600 PM CDT Sun Apr 12 2026

   Areas affected...Northeast Minnesota

   Concerning...Severe potential...Watch unlikely 

   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. 
   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.
