A significant heatwave develops across southern and Central Europe through this week, with the UK on the boundary between these hot conditions and much cooler conditions to the northwest.
Fronts along that boundary will bring cloud and rain at times, especially across the north and west of the UK, but there will be some drier and brighter conditions which will be most frequent in the south and east.
It will be very warm to hot for south eastern areas of the UK, reaching the high twenties and at times the low 30s in the hottest spots, but cooler further north and west.
A small chance that the more significant heat over the near continent affects parts of the UK early next week, but high uncertainty with an equal split between that and somewhat fresher (but likely still warm) conditions.
