Heavy, thundery showers are likely to break out by day, particularly on Sunday when these could be widespread and locally torrential. Lightning and hail are also expected. Rainfall amounts will vary from place to place, but there is the potential for up to 100 mm to build up in some locations over the course of the weekend, much of which could fall in a short period of time.
