When outdoors in the evening, the burn limit keeps going up as the sun and UVI goes down faster than UV exposure accumulates.
Conversely, morning burn limit projections would be too long as the sun and UVI will get higher before then.
A simple time of day projection of UVI would allow more accurate burn limits, even without any forecasting of future cloud cover %.
