Castlebay (Na h-Eileanan Siar) weather

Headline:

Rain spreading northeast on Saturday afternoon.

This Evening and Tonight:

A mostly cloudy evening with some clear intervals and showers, which may be heavy at times. Showers still around overnight but longer dry spells developing. Windy near the coasts. Minimum temperature 4 °C.

Saturday:

Mainly dry in the morning, some occasional rain at first. Through the afternoon a band of heavier and more persistent rain spread northeastwards over the area. Maximum temperature 9 °C.

Outlook for Sunday to Tuesday:

Remaining unsettled with blustery heavy showers spreading eastwards and at times longer periods of rain. However, still some dry spells with occasional brightness. Breezy throughout.

Changeable during this period with Atlantic frontal systems moving across the country and shorter dry and bright interludes in-between. Rain and showers typically heaviest and most frequent in the west, with more sheltered eastern areas seeing much smaller amounts of rain. Often windy with a chance of gales at times. Temperatures well above average at first, likely falling closer to average with alternating colder and milder spells towards the end of February and into March; perhaps cold enough for some sleet/snow showers in the northwest, especially over high ground, in the colder spells.

A continuation of rather changeable conditions is the favoured scenario, with low pressure systems tending to pass close to or across the UK, bringing occasional spells of wet and windy weather, especially in the north and west. High pressure to the southwest may build across the UK at times to bring some drier, quieter interludes, these more likely later in this period and probably most influential in the south - the chances of prolonged settled weather look very low. Temperatures are likely to be near or slightly above average for the period as a whole, though some relatively short-lived interludes of colder conditions remain possible.
