GENERAL SITUATION AND SYNOPSIS 06:00 UTC

A slack area of relatively low pressure lies across the British Isles, with a light E to NE’ly airflow over the Northern Isles. Weak fronts in its circulation are likely to affect the north of Scotland from time to time.

A freshening SW’ly airflow will develop later on Sunday, ahead of Atlantic fronts forecast to be driven eastwards by a depression in the Iceland region.

Current predictions suggest a more changeable and stronger SW’ly airflow for next week.

A daytime high of 13° to 14° Celsius, with overnight lows of about 10° Celsius.

FRIDAY 24th: Today starting misty or foggy with extensive low cloud, but this slowly lifting and breaking with some bright or sunny spells possible in the west, while coasts and hills exposed to the F3 NE’ly wind likely to see mist and low cloud. Perhaps an isolated shower over Orkney, otherwise a dry day. The mist and low cloud becoming more widespread overnight, perhaps with some drizzle.

Sea State: Mostly slight, with a 1 metre E to NE’ly wind-swell.

SATURDAY 25th: Rather cloudy, grey and misty with some drizzle, but perhaps a little brighter in the west for a time, with the chance of some sunshine for Orkney. F3 NE to N’ly winds.
