Cracker shots John!!!. The first one looks the most inpressive. Must have been a major cell you had passing through!. That's got to be on the best mammatus catches from here in recent times. Keep an eye out tommorow for more.
I seen over two dozen mammatus displays today. The best was this one which formed under the anvil of a giant gust front which produced horizontal rain and hail. The winds must have been gusting at 40-50mph when it hit. The mammatus were very large and hung down to a great depth. This is wide angle.
