UK Outlook for Saturday 25 May 2013 to Monday 3 Jun 2013
Through the Bank Holiday weekend an east-west split is likely to develop, which looks to continue through much of this period. The most settled conditions will be in the west, together with a few showers, best of the drier, brighter weather in the southwest. In the east, more unsettled conditions with sunshine and sharp showers, with some heavy rain possible at times. It will be windy at times, especially in the east with a risk of gales in more exposed areas and a chance of mountain snow for northern Scotland. Temperatures will be below average across the country, but towards the end of May the more unsettled weather is likely to shift to the northwest of the UK, with temperatures returning to nearer average for the start of June.

UK Outlook for Tuesday 4 Jun 2013 to Tuesday 18 Jun 2013
There are signals that conditions should begin to settle down into the beginning of June, becoming drier than normal for many areas, especially across the west with the influence of high pressure extending from the Azores. Temperatures should also return to normal for early June, so feeling pleasantly warm in the sunshine, but currently no signal for heat wave conditions, and feeling cooler around coastal areas where sea breezes develop. Variable amounts of cloud are likely around the country, but also interspersed with sunnier conditions. Some showers are still possible through the period, especially in the east.
