I wonder whether similar methods could be used for temperature drops, or wind changes, when a front is coming in. Both pieces of data can be sourced from nearby weather stations, and it's more predictable even over a 4 hour period.
In some ways this is a "warning" app. So high winds, temperature change, rain - and localised BOM warnings too - seem part of it.
(Only just got the app, looking forward to using).
I’m not sure what value that would provide, it already has rain warnings, the only other one would be high wind warnings, but once you are getting into that territory there is often a rain front associated with the high winds anyway.
