Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque like *'продленный прогноз.'* Correct: 'долгосрочный прогноз погоды' or 'прогноз погоды на длительный период.'
- Do not confuse with 'detailed forecast' ('подробный прогноз'), which is about granularity, not duration.
Common Mistakes
- Using 'extended forecast' to mean a forecast that has been updated or corrected (that's a 'revised forecast').
- Confusing with 'extended warranty' (a different domain).

Yes, metaphorically. For example, 'The CEO provided an extended forecast for company growth over the next quarter.' It means a long-term projection.
They are often used interchangeably in weather contexts. However, 'outlook' can sound slightly less precise and more focused on general trends, while 'extended forecast' implies a more structured prediction.
