Do they mean 'short term up to midnight' or... this a just 3 second briefing of what the weather may be like tommorow.

Possibly , if you want a more detailed forecast then go to their website and there you will get a more detailed forecast for your area up to a certain period.
I haven't found that yet. Just a 'short' forecast as what they have said on the radio or telly.
If you look on their website, i can't find any elongated forecasts apart from their Severe Weather Outlook.
There are the apps, rural, mountains forecasts etc, but the term short is unsatifactory in my books as far as weather forecasting goes.
