Low pressure centred south-west of Iberia brings heavy rain and possible thunder to southern regions of Spain and Portugal. Northern and eastern Iberia should stay dry; highs 17 to 22C. Low pressure and a slow-moving frontal system across central & south-eastern Europe brings areas of heavy rain and showers to Alpine countries, plus the Balkans, the Czech Republic, Slovakia and Poland. Dry and warm conditions continue around the Black Sea and also Greece, topping 25C. Showers are likely in Italy, whilst southern France sees a strong Mistral wind. Scattered showers for northern France and the Low Countries, and cool at 11 to 13C. Areas toward the Pyrenees will be dry, highs of 15C. A shallow low over Denmark brings areas of rain to southern Scandinavia, plus snow to mountains of southern Norway and Sweden. High pressure over northern Scandinavia brings settled weather for the far north and the Baltic.
A trough of low pressure affects Iberia, bringing clusters of thundery showers to Spain, whilst Portugal should be dry - highs of 20C. Slack high pressure over the western Mediterranean and western central Europe brings fair weather to Italy, the Alps, the Low Countries, much of Germany and France. Rain develops for the Biscay coast later, whilst a few showers are possible in eastern Germany - these also affecting Poland. A cold front extends across east & south-eastern Europe, bringing persistent bursts of rain to western Ukraine, Romania and the southern Balkans. Meanwhile, Greece, the eastern Med and areas around the Black Sea stay dry and very warm, into the mid-high 20s Celsius. Low pressure pushing north brings rain to the Baltic states and later Finland. Brisk easterly winds for much of Scandinavia, but high pressure to the north maintains plenty of dry weather.
