There's reduced data available for initial conditions, so I wonder how that will effect things:

A good book on the history of forecasting, The Weather Machine: A Journey Inside the Forecast:
There is a great article from the German Meteorological Service on WeatherNext 3 and how AI-based weather models will probably co-exist with physics-based ones.

It’s crazy we’ll never have forecasts as good as dark sky again. What kind of magic were they doing?
The exploration page is really easy to use. Having more reliable weather predictions is a genuinely useful product.
They even have an interactive world map with all the layers. It's so cool when an announcement comes with the actual goods.
Is there a convenient way to use this on iOS? AFAIK Google Search and Maps only show rather basic information.

The online viewer could really, really use Wind Direction as a compass bearing. Its super important considering wildfire/bushfire, air quality, ocean-going conditions, and a myriad of other things. It is produced as a set of vectors during model creation, so would be very useful to see.
In the energy world, this should be such a boon over the classic NWP (Numerical Weather Prediction; complex ML models), but I've not seen it implementated. Anyone with experience of these models over classic NWP?

TLDR: the input data for the model now also includes real-time observations (satellite and weather stations) on top of the typical (re)analysis data, improving model resolution, run frequency and timestep frequency.

It's great that they're working on this, but I am puzzled at how absolutely awful the forecasts are in the Google weather app for my area. The forecast will show no rain, the radar view shows nothing, meanwhile it's pouring outside and every other app I check shows it. I know I can't expect it to be perfect, but being terribly wrong even one in ten times is enough to tarnish its reputation permanently.
