Lerwick (S. Screen) (Shetland Islands) weather

Headline:

Mainly dry with the odd shower today. Light winds.

Today:

Variable amounts of cloud with some bright or sunny intervals. A fair amount of dry weather but one or two showers may drift in off the sea. Light and variable winds. Maximum temperature 6 °C.

Tonight:

Mainly dry this evening with just the odd shower. Then the rest of the night will be cloudy at times and mostly dry, just a brief shower. Cold. Light winds. Minimum temperature 2 °C.

Thursday:

Still one or two showers across Shetland and Fair Isle, Orkney will be dry. Some bright spells too. Freshening southeasterly winds in the evening. Maximum temperature 6 °C.

Outlook for Friday to Sunday:

Mostly dry at first on Friday but wet and windy extending north. Frequent showers on Saturday with severe westerly gales at first, easing later. Still a few showers on Sunday.

This looks like being and unsettled period across much of the country, but especially for northern and western parts. During Monday, another deep area of low pressure looks likely to move across the UK from the Atlantic, bringing wet and windy conditions to most if not all parts. Further spells of wet and windy weather look like moving east from the Atlantic to affect the UK during the rest of the period too, with drier, brighter spells in between. There is the potential for further weather warnings or even a named storm at some point. Temperatures overall are likely to end up being around or slightly above average, though wind and rain will make it feel chilly, and brief cool spells with some overnight frost are likely between weather systems.

Generally mild at first, with periods of rain, showers and strong winds alternating with short-lived brighter and cooler interludes. With time, these may become increasingly confined to northern parts, with pressure possibly building across southern areas. This would result in longer drier and more-settled spells here, albeit with an increased chance of overnight fog and frost with temperatures falling correspondingly.
