UK long range weather forecast
There should be a gradual change in conditions through this period as the warm or very warm weather will most likely be displaced east and southeastwards. It will be replaced by fresher, changeable conditions from the west. There should still be a good deal of fine and dry weather across the UK through the period. However, there is a continued risk of heavy showers and thunderstorms in many areas, particularly across the south earlier on in the period. It will be widely warm or very warm at the start of the period, and it could be hot in the southeast at times. Towards the end of the period, temperatures will trend back to near the average for most areas, with the southeast possibly staying warm.
Updated:
Confidence remains fairly low for this period. The south is most likely to see the best of any fine and dry weather as westerlies and southwesterlies dominate. Elsewhere could see some periods of dry and settled weather interspersed with occasional bouts of wetter and windier weather, primarily from Atlantic frontal systems. The wettest and windiest conditions will most likely be towards the northwest, with the southeast staying driest. Temperatures will be most likely around average or slightly above. There could be some short-lived very warm spells, most likely confined to the south and southeast of the UK.
