A generally rather changeable period looks likely, with many places likely to see some much needed rain or showers at times but also some more sunshine. Initially, some rain or showers will affect many parts, this heavy and possibly thundery in places. After a drier, brighter few days, further changeable or unsettled conditions may develop as we head towards mid-August. This may be due to frontal systems moving in from the Atlantic or thundery plumes moving north from the continent or a combination of both. Temperatures will likely be a little above average overall, and there is the potential for some very warm or hot and humid spells, especially in the south, although perhaps not the heat we have seen in recent weeks.

Predominantly dry and settled conditions look likely for much of this period, with high pressure patterns tending to affect the UK. This may be interrupted at times by Atlantic frontal systems, especially in the north, or thunderstorms in the south. However, overall, rainfall amounts will likely be below normal. Temperatures will probably be above normal and some spells of hot weather and heatwaves are possible, especially in the south.
