Angry sky

Things change fast...blue sky this morning, and now this.
On my lap top I find that the angle of the screen is critical when you look at this image, so please do play around for a second or two.

The weather gods must know I'm flying to the UK to-morrow, Friday.
Day in London, 2 days in Brum [my first stock car meeting of the season] then back here late on Monday evening, followed by our first theatre production of the year.
It's all happening!
No wi fi where I'm going, so no blips until Tuesday, I imagine, sorry about that but hope to back blip.
