A bit of luck for southern England & Wales tomorrow: The band of cloud now looks to move through a lot faster, such that another day of plentiful sunshine occurs. Still unseasonably cool air, but like today, that sunshine should feel warm thanks to it being just a little breezy.

Wowsers! I've NEVER seen this before!🤓

I *think* this explains it:
Rainbows are circles. When the sun is low you see more of the arc. When the sun is above 42° the rainbow slips below the horizon. Here I think the sun is just below 42° so you only see the very top. Amazing!😍

Not sure I’ve ever felt such relief & joy at the sight of mud drying out.

Looks like a chain of mesoscale convective systems (MCS) moved along a convergence line, each time initiating over the very warm waters.

An extremely rare setup in that part of the world, which at least means it shouldn't reoccur for a long time (not guaranteed though).
