General Situation:Another cool and unsettled weekend in store as low pressure continues to dominate.  Wet and windy across England and Wales on Friday and again on Monday, with Scotland more showery and all parts seeing showers on Saturday and Sunday, though lighter and more scattered, especially in England and Wales, on Sunday.

The Weekend in Detail:

Saturday 18th June -  low pressure centred over the British isles with frequent showers affecting most parts, some of these heavy and possibly thundery over Wales.  Cloud down over summits for the most part.  More general rain affecting much of Scotland, particularly across the Central and East Highlands and Perthshire.  Tending to become brighter, especially towards coasts, in the North and West Highlands in the afternoon. Cool everywhere but winds mainly light or moderate except towards the SW where stronger southwesterlies can be expected.

Sunday 19th June -  again a scattering of showers around, though these lighter and less frequent as a front over Scotland and northern England weakens and a weak ridge of high pressure briefly builds from the south.  North and West Highlands again likely to see the best chance of some brighter spells between showers in Scotland, with cloud thicker further east.  Low cloud also likely to affect the Southern Uplands and the North Pennines, with some rain at times.  However most other upland parts of England and Wales also likely to see some brightness at times and at least have lower summits clear.   It looks there'll be thicker cloud pushing in from the west across Ireland into Wales later in the afternoon and through the evening.  Another cool day with mainly light or moderate winds.

Further Outlook: Low cloud, rain and strong winds again spreading across England and Wales on Monday, but a drier day in Scotland with some bright spells and even a chance of cloud free summits, especially in Torridon and Sutherland .  Winds lighter here too and temperatures a little up on the weekend.   Thereafter, the unsettled regime continues although there are signs that high pressure will develop in the Atlantic and should drift over the south of Britain next weekend with briefly some drier and slightly warmer, though still cloudy conditions for England and Wales.  Scotland remaining largely unsettled throughout though.
