Why? Isn't that the whole point of a computer model - I'd be surprised if it wasn't 😁
Depends. Most of the models are global so looking at the big picture, not relatively small features or even widespread small features. They're also pretty poor (even the higher res ones that are designed for looking for such things) at accurately modelling said features at more than 48 hours or so.
So no, I wouldn't expect the models to be correctly factoring in things like convective enhancement from the LP at that range.
All that said, the chart is 'FI' so unlikely to verify as shown and there's more to whether showers form than just LP being nearby so it's possible I'm totally wrong!
