48-48: Consider improving regex maintainability.The regex pattern is complex and could benefit from better maintainability. Consider these improvements:
- Use named capturing groups for better readability
- Break down the pattern into smaller, reusable components
Example refactor:
- return $@"(TEMPO|BECMG|NOSIG)\s*(?:AT(\d{{4}}))?\s*(?:FM(\d{{4}}))?\s*(?:TL(\d{{4}}))?\s*({windRegex})?\s*({visibilityRegex})?\s*({presentWeatherRegex})?\s*({cloudRegex})?\s*((?=\s*(?:TEMPO|BECMG|NOSIG|$))(?:\s*(TEMPO|BECMG|NOSIG)\s*(?:AT(\d{{4}}))?\s*(?:FM(\d{{4}}))?\s*(?:TL(\d{{4}}))?\s*({windRegex})?\s*({visibilityRegex})?\s*({presentWeatherRegex})?\s*({cloudRegex})?)?)"; + const string timeRegex = @"\s*(?:AT(?<at>\d{4}))?\s*(?:FM(?<from>\d{4}))?\s*(?:TL(?<until>\d{4}))?"; + const string trendGroup = $@"(?<type>TEMPO|BECMG|NOSIG){timeRegex}\s*(?<wind>{windRegex})?\s*(?<visibility>{visibilityRegex})?\s*(?<weather>{presentWeatherRegex})?\s*(?<clouds>{cloudRegex})?"; + return $@"{trendGroup}\s*(?=\s*(?:TEMPO|BECMG|NOSIG|$))(?:\s*{trendGroup})?";

48-48: LGTM! The regex pattern now correctly starts with trend options.The removal of the "TREND" prefix aligns with the PR objective and maintains all necessary capturing groups for proper trend forecast parsing.
