A very nice day, light winds mean I can carry on with fibreglassing.. on my birthday...
Temp: 21.3°C - Hum: 59% - Dew: 12.9°C - Bar: 1013.75hPa - Wind: SE ~ ESE @ 6mph.
It's down to the 'rolling shutter' effect, of the camera. It can happen vertically and horizontally as the camera scans rows at a time, rather than the whole image in one go.
I don't wish to brag, but my temp is now at 16.4°C, DP is 15.4°C and inside temp is finally down to 26°C - no fan needed on the aquarium tonight, yippee!
I've just been out for a wander, its actually sea mist that has come this far inland. It does it on rare occasions. Despite a nice breeze now, its eerily orange outside.
There's actually more capping further North than there is down here. The profiles are drier though, so not much in the way of moisture to aid anything.
I disagree with the criticism of Keithy Joe. Estofex practically say the same thing. Very large hail, damaging gusts, and tornadoes. If that isn't severe and dangerous, then I'm missing the trick.
