Showery (5)
I believe the answer is:
rainy
'showery' is the definition.
(I know that showery can be written as rainy)
This is all the clue.
(Other definitions for rainy that I've seen before include "The day one saves for" , "Save your money for a . . . . . day - to buy an umbrella?" , "Wet, showery" , "(Of weather) wet" , "With water falling outside" .)
