For the eclipse, I was using hyperlocal forecasts for the next day (and next two) for planning for which direction to go, where to stay, and where to head the next day.

The morning of the eclipse it was a question of "this town or that town or that other town at this time."

This may be an edge case, but there are certainly times where prediction for a certain time 24h or 48h in advance is useful.

What were you using for hyperlocal projective forecasts that far in advance?

Weather app, yr.no (e.g. https://www.yr.no/en/details/table/2-4235193/United%20States... ) , myradar, and pivotalweather (which gave access to a number of different models). In the case of things that gave maps, it was "look at the location on the map".

It wasn't necessarily "I want to know the weather for this block" but "I want to know the weather for this square mile."

One of the features that I liked in Dark Sky of very old (it was removed well before Apple decided to buy them) was the Lines feature which showed the models that it used. Knowing how to get at and read the models themselves (and asking the weather geek who I work with about the strengths and weaknesses of each model - "well X is good, but it over predicts precipitation and cloud cover within 50 miles of a lake that can produce lake effects, but if you're not near a lake its spot on for...").
