UK long range weather forecast
Continuing unsettled and rather cool with showers developing on most days. Each day the showers are likely to be locally heavy with the risk of thunder, perhaps parts of the south most prone to these on Monday. It's likely to be breezy at times too, especially around coastal areas in the west. Temperatures look to remain rather below average across the country, although in any sunshine and lighter winds it will feel quite pleasant. Where winds fall light and skies clear it is still possible we could see some overnight frost in sheltered, prone locations. Perhaps beginning to turn rather more settled toward the end of the period, but this very uncertain at this stage.
Updated:
Confidence is low for this outlook as is typical of late spring and early summer. However perhaps a trend to rather more settled conditions as we move into early June with more in the way of dry weather and sunshine. With this we are likely to see a recovery in temperature too, although at this stage there is no strong signal for any very warm weather.
