Minnesota Outflow

Storms in Minnesota that produced violent tornadoes on Thursday congealed into a damaging squall line that dove SE across IA during the overnight. This squall line eventually lost its intensity however, the wind energy continued moving and eventually canvassed Central IL at around 6AM on Friday. Though harmless by itself as it is simply two colliding air masses of differing temperature and moisture content near the surface, it did enhance an ongoing local storm to the NE resulting in a brief tornado warning for Piatt and Champaign counties.
