Ha, three very good answers.... But only one correct one!
It's primarily because the suns UV is lowered during rain, which can interfere with broadcasted RF signals. The same thing occurs during the night; however most TV/Radio stations know when this happens (duhhh), and they reduce their transmitter power output accordingly.

Rain improves the electrical connection on aerials whose connections are corroded or rusty ! . Rain makes no difference to an aerial in good condition !!. Sometimes if the aerial is facing a bunch of trees in full bloom then the wet leaves can effectively shield the aerial from the TV signal . That's a case of rain making reception worse . True ----Never heard that one Jim , what about just a local rain shower ?. Now I have heard of the Heaviside Kennely layer which is at a lower altitude at night which affects long distance radio communications on the short wave band . not heard the UV theory though ! must be getting old !

VHF/UHF waveform signals bounce back off clouds towards the ground (and people's aerials). When it's clear more of the signal escapes into the atmosphere. True!

The clouds can act as a repeater for the signal.
