Down here in Penzance we had the driest May I've recorded (since 1991) despite 14mm in 40 minutes on 10th. Extremely localised, a virtually stationary sea breeze convergence deluge, something Cornwall's famous for with the 2 opposing coasts.
Anyway, the droughts ended. Woken by heavy rain around 04:30, then again by thunder & heavy rain about 05:15. Still raining, but just steady. Total of 17mm so far, but more to come.
1st thunder of the year. (I must check if that's a record wait) There were 3 days with thunder last November.
Signs of another change in a week or so's time? Certainly hinted at for a couple of days.
