Parish Short Range IN

The NAM is showing strong frontogenesis on Sunday March 31, 2013 at 6 UTC. The first image below shows frontogenesis at this time. This strong fronotogenesis is caused by deformation and convergence. The second image below shows deformation with the axis of dilation going right through Indiana. This acting to contract the isotherms. The third image below shows strong convergence over the state of Indiana on Sunday March 31, 2013 at 3 UTC. The deformation at 3 UTC definitely induced the frontogenesis at 6 UTC on Sunday March 31, 2013.
