I loved the descripton of England, the paranoia about the rain. Although my faith in the police leads me to hope that they would still be out there, rain or no rain
I was a bit confused because when you described it as being Tyler's last day, I thought last day of life rather than last day as a policeman, so I was wondering why he hadn't died, not that I'm complaining, he seems like a good man.
Loved the line about wishing the Vulcans would come to England! That made me laugh.
It seems a bit of a pun to say a story called Rain is atmospheric, but it was - it seemed very real to me, with all the rain England gets normally, I can see that another world war could easily cause constant rain, and that it would slowly drive everyone insane!
I too would like to see more of this world.
