For example, they often show the animation of the rainfall radar as an
"aftercast", but I'd like to see a simulated rainfall radar animation
for the day ahead. This shouldn't be beyond the abilities of the
technical team and would give a good indication of how broken up or
solid the rainfall coverage is going to be.

Michael,
It's just a animated record, there is no element of forecasting. An
'aftercast' is something quite different.
I'd quite like to see such a simulation, however although it might not
be beyond the abilities of the technical team I'd say it is beyond the
abilities of the forecasters. Any forecast of rain presented
graphically is necessarily a pretty smudgy affair. Just look at the ever
changing detail in the radar images (assuming that it's the truth), that
detail or anything near it can never be forecast for a day ahead, I
think even just 'broken up or solid' is pushing it. The current
broad-brush attempts could be made a lot clearer, and maybe will.
Perhaps that's all you are asking.

Regards
Tom
