Today didn't turn out quite as expected. I thought it was going to be a fine day and was hoping to visit Covenham Reservoir. The morning started out a bit on the damp side and there was a cool breeze for much of the day.
Suddenly, about 3.30 in the afternoon it got so dark I had to switch the room lights on. Then the rain started accompanied by thunder and lightning which got closer and closer. The rain became heavier until it was like a tropical storm.
This continued for about three quarters of an hour in which time 0.85 inches (22mm) of rain was recorded. As a result my lawn which had been free of standing water started to become a lake.
These sorts of short sharp storms are not rare in the summer months but I usually expect them after many days of glorious sunshine.
