Some discussions have state that forecasts, even less than 24 hours out have not been substantially inaccurate. I experienced this last year when a storm came in 16 hours before the forecast. I even pulled a detailed forecast to see if it made a difference. I made the decision to have one more night out and leave early morning, well before the forecast arrival. Instead it starting pouring that night making for a miserable hike out to the trailhead. I haven't trusted it since. But want to hear from others.
