Our country weather, wet, beginning to enter this country (7)
I believe the answer is:
ukraine
'this country' is the definition.
(Ukraine is a country)
'our country weather wet beginning to enter' is the wordplay.
'our country' becomes 'UK' (United Kingdom).
'weather wet' becomes 'rain' (rain is wet weather).
'beginning to' indicates taking the first letters.
The initial letter of 'enter' is 'e'.
'uk'+'rain'+'e'='UKRAINE'
(Other definitions for ukraine that I've seen before include "One country" , "Country bordering Russia" , "Eastern European country" , "Former state of USSR now a republic" , "East European country" .)
