High pressure will continue to dominate across many northern areas of Europe maintaining mainly dry weather, but with thundery showers elsewhere despite some sunshine.
Into Wednesday and not a great deal of change in the weather is forecast. High pressure persists across much of Scandinavia while continuing to influence the weather across the British Isles as well with further dry, settled and warm conditions across more northern areas of Europe in general. Elsewhere and the mixture of sunshine and afternoon thundery downpours are predicted, again primarily focused across parts of France, eastwards into more central areas of Europe, down into Italy and also across Iberia too. Some longer spells of rain may actually develop across Portugal as well through the day in association with low pressure just to the west. Warm or very warm for much of Europe, but particularly hot across more eastern areas of the Med including Greece, Turkey and surrounding countries.
During Thursday and a large and dominant area of high pressure persists over Scandinavia bringing fine and warm weather to much of Norway, Sweden and Finland. These fair weather conditions also continue to dominate across much of the British Isles, but with a few showers possible across S England as the day progresses. The remainder of Europe is void of any active weather systems so while plenty of warm or very warm sunshine is forecast, atmospheric pressure is low enough to allow for the development of fairly widespred afternoon heavy showers or thunderstorms. It remains likely that most of these will be across parts of France, eastwards into Germany and parts of Switzerland, while potentially affecting Spain and Portugal still as well given that low pressure persists here. Plenty of fine and very warm weather for eastern and south-eastern areas of Europe, hot in fact across Greece, Turkey and Slovakia, for example, but with afternoon downpours possible.
