A really fascinating cloud formation at the very leading edge of the storm.
The four photos were taken between 5:20 PM and 5:21 PM...that's how fast it was moving.
All the photos enlarge when clicked.
We had about 20 mm of rain in the hour or so following this amazing display and further soft rain today.
Nice...and very welcome.
UPDATE - Monday 23rd.
The area newspaper The Daily Examiner published two of the above shots, along with some from other contributors, in today's edition.
I also learned that the type of cloud formation is termed a "shelf cloud", or "shelf front".
