Folks,

Raining pretty hard on the top of the Yorkshire Wolds this morning, but only under the trees. Had to use the windscreen wipers after passing under every sizeable, mature, roadside ash or oak. Best guess, 2-4 mm h-1, but sort of dependent where you'd stuck the rain gauge.

Some of the thickest fog of the year was the source of the moisture, 20-30 m visibility at its dimmest. Altitude dependent, with the whole of the upper Wolds (220-230 m) soaking, by 100-120, pretty much disappeared. Visibility at 50 m asl was 1 km.

Interesting snippets like this keep me coming back for more despite the stunning ignorance of a rather dawlish crew. Just have to dig eh?

I wonder how much moisture trees manage to put into the soil on misty spells. And how much our environments have changed since 2 world wars caused farmers to change the way they manage their fields. A long term time bomb in every turn of their screw no doubt.
