First -- thank you developers for integrating this forecast.
Second --
the warnings about how the tail end of these longer forecasts are less reliable has no visual indication on the forecast, nor any way to disable this longer-term, less accurate forecast. That caveat only appears on the announcement of this product.
Likewise, there should be a visual cue that after day ~6 or so, the forecast is not of the same level of accuracy. Perhaps a change in background or hashing to visually cue the less accurate tail end.
EG When NOAA releases its extended hurricane forecasts, you'll notice that the cone gets larger and the central line of the path is disabled by default. This is because there is less certainty.
Personally, I'd rather have a button to turn off this 15-day completely and revert to the old week long forecast. It's hard to read on my iPhone and I know it's less reliable.
Thank you,
