Urge to take time in making forecasts (8)
I believe the answer is:
presages
'forecasts' is the definition.
('presage' can be a synonym of 'forecast')
'urge to take time' is the wordplay.
'urge' becomes 'press' (synonyms).
'to take' is an insertion indicator (inserted letters are taken in).
'time' becomes 'age' (an age is a period of time).
'press' enclosing 'age' is 'PRESAGES'.
'in making' is the link.
(Other definitions for presages that I've seen before include "Forecasts" , "Augurs, bodes" , "Foreshadows, is advance sign of" , "Foreshadows in press age" .)
