It is absolutely pouring outside. But my weather app thinks it’s just cloudy.
Why is it that weather apps seem to be less accurate in the early summer time? So often it’s spot on with “the rain will stop in 20 minutes” but then there’s these storms that everyone on the ground knew were coming but the radar couldn’t predict.
I’ve always wondered where this data comes from. The national weather service provides hourly data with observations from airports.
I’ve wondered where the higher resolution data comes from … Might even just be interpolation to the next forecast? Or some sort of radar based model?
