Mammatus clouds in Pigeon, storm turning further right, now tracking south across Saginaw Bay

The threat to northern Huron County may not be as robust as I anticipated.  The storm looks to be tracking south, and now appears to be weakening again a bit, as another cell looks like it popped up and stole a bit of the initial cell's energy.  VERY strong rotation was over the bay at one point, but has since waned a bit.

Looking up in Pigeon under the anvil of the storm yielded something very exciting for me, though. For the second time in my life I've now witnessed mammatus clouds, and this time under a storm rather than under altocumulus.
