Clearing skies in parts of northeast Minnesota this afternoon is leading to an unstable atmosphere. Cold front and upper low approaching from the west will move into this warm, humid and unstable air which should cause scattered thunderstorms to develop through early this evening. A few storms could be strong to severe, but not everyone will get hit as these storms should remain isolated to scattered in coverage.
Seeing some decent convergence setting up this afternoon with south-southwesterly winds ahead of a cold front and west winds behind the boundary.
