Like the weather in Crewe tomorrow (3)

I believe the answer is:

wet

I'm a little stuck... Click here to teach me more about this clue!

'like the weather' is the definition.
I can't judge whether this definition defines the answer.

'in crewe tomorrow' is the wordplay.
'in' indicates a hidden word.
'WET' can be found hidden inside 'crewe tomorrow'.

Can you help me to learn more?

(Other definitions for wet that I've seen before include "Damp" , "Moisture; feeble (colloq.)" , "Rainy; feeble person" , "Rainy (weather)" , "Moist or Soaked" .)

I've seen this clue in the Evening Standard.
