I also was nearly put of by Sunday's TAF but still managed to get to my destination. Took me an hour against the headwind and 40 minutes to get back with only one slight diversion to avoid a chunky big (cb) cloud. as I went around it I was "followed" by a rainbow. Marvellous. Viz was fantastic as well.
Whilst putting the wunderplane away in lovely sunshine I watched a massive cb passing to the East. Turns out that my house 5 miles from the airfield was being deluged with hailstones!
