Friday is likely to be a showery day with variable but often large amounts of cloud. Any sunny spells may trigger heavy showers with a risk of thunder and showers may merge to give longer spells of rain across the north and the far south. Temperatures should be near to normal. This changeable weather is expected to continue into the Bank Holiday weekend with strong winds and spells of rain likely, at first, before clearing to a mixture of sunshine and showers. Showers may become heavy and thundery across southern areas with temperatures generally near to or slightly below average. The rest of the period remains rather uncertain, although the weather is expected to become largely settled interrupted by spells of changeable weather.

Confidence in the forecast is low for the first half of June, but the most likely scenario is for a slowly evolving weather pattern to become established, with Atlantic weather systems struggling to make eastwards progress across the UK. Overall, settled weather is most likely across northern parts of the UK, but these settled spells will extend to all areas at times. These periods of drier and settled weather will occasionally be punctuated by cooler, showery spells as Atlantic weather systems arrive from the west, albeit temporarily. Temperatures are likely to trend mostly close to normal as we move through June.
