7pm 250mb map showing an amplified trough over the western CONUS. Strong synoptic-scale lift is implied over MN at the nose of the jetstreak and within the diffluence in the wind field. | 7pm 850mb map showing a deep, closed low over northwest MN. A very strong LLJ (45kt wind barb at MPX) has dragged ample moisture into the Upper Midwest. | 8:30pm surface map showing a deep surface low with a warm front extending east across MN while an arcing cold front trails south. |

4pm map of surface-based CAPE. Strong instability is analyzed over southern to south-central MN with +3000 J/kg of CAPE. | 4pm map of effective bulk shear. 60 to +70 knots of shear across MN signals a very favorable environment for rotating thunderstorm updrafts. | 4pm map of effective storm relative helicity. Higher values mean a more favorable environment for faster rotating updrafts. |
