Planning Outlook

The weekend is often cloudy in north and west Scotland, some drizzle on the summits with occasional light rain, amounting to little. Drier south and east Scotland, but cloud will reach here too, particularly on Sunday. England and Wales will be largely dry and bright this weekend with little wind and mild temperatures. On Sunday, high pressure west of the country may facilitate local inversion conditions, but low cloud likely quick to fade. Next week begins dry and bright, but wind shifts southeasterly and pressure drops again as the week goes, bringing periods of cloud and rain (sometimes heavy) to most hill groups, some stronger wind at times. Similar conditions persist into the following weekend: generally unsettled but a chance of a settled window, best in the east.
