NWS doesn't do regular daily/hourly forecasts beyond a week, but they do publish "extended range outlooks" which provide probabilities for precipitation and temperature in the 6-10 day and 8-14 day range. Pretty low-res in both temporal and geographical resolution, though, due to the uncertainties: https://www.cpc.ncep.noaa.gov/products/forecasts/extended_ra...
I never used the WU app, but I do use the WU website regularly and feel that it is very slow and spammy and bad UI, etc., etc.
The problem is, I cannot find anyone else to give me a 10 day forecast.
How can I tease out a 10-day forecast from weather.gov ?
