How we produce the weather forecast which will tell you what it will be like in a few hours' time.

At short time ranges a higher level of detail can be forecast with more reliability and very short-range forecasting is known as nowcasting.

At short-range we use higher resolution models to pick up the smaller (meso-) scale details.
