UK Outlook for Saturday 3 Jun 2017 to Monday 12 Jun 2017:

Details are rather uncertain for next weekend, however, rain is most likely to clear eastwards early on Saturday with drier, brighter, fresher and showery conditions following from the west. Further cloud and outbreaks of rain are then likely from the west early next week. Through the rest of the period, a more changeable pattern is likely across the United Kingdom, with northern and western parts seeing spells of rain at times. Meanwhile, many southern and eastern parts should be drier and brighter, although some spells of rain possible here too. Windy at times, especially in the northwest. Temperatures are likely to be near normal generally, but perhaps warm at times in the south and east.

UK Outlook for Tuesday 13 Jun 2017 to Tuesday 27 Jun 2017:

Confidence is low during this period, although we are likely to see the changeable pattern continuing across the United Kingdom through the period, with a predominately west or southwesterly flow and near normal temperatures. The unsettled conditions most frequently affecting northern and western parts, but also further southeast at times too. By late June confidence remains low, although on balance we are likely to see a continuation of the changeable conditions for many, with temperatures remaining near the average, although some warmer spells remain possible in the south and southeast at times too.
