The majority of models have to parameterise (approximate) convection such as showers and thunderstorms but a few explicitly model individual convection such as ACCESS-C, HRRR (used in the US), etc and you can often see individual showers and storms in such models (see above example for 1hr accumulations from onshore showers in ACCESS-C) as well as convective features such as MCS's.
You can also often see outflow boundaries from storms in EC due to its high resolution (about 9km).
