Meredith and Emma came over for dinner Saturday night - pretty normal.  We even went for a quick swim before dinner - also pretty normal.  What wasn't normal was the weather.  It had been over 100 degrees that day (while I was mowing, weed-eating, etc.) and then some clouds blew in, cooling it down a bit.  It was coolish when we went swimming, and then....this happened:

Emma got this great panoramic shot:

We decided that swimming was a bad idea when the lighting and thunder started.  It was a fast moving storm though - this was sunset later that evening....and it was cool enough we sat outside for dinner - unusual for this time of year.
