I absolutely love windy.com. Prior to having a ForeFlight subscription, I found it to have the most accurate hourly forecasts before heading up on a flight. Both the website and mobile app are stellar, and they put extra effort into building tools for pilots. They have the best visualizations for cloud layers, let you toggle UTC time, and they integrate with airport info beautifully. I’d set notifications on METAR updates prior to heading out so I’d stay up to date.
