Giosla (Na h-Eileanan Siar) weather

Headline:

Bright and warm in east Thursday. West seeing drizzly rain.

Today:

Eilean Siar and the Northwest Highlands remaining cloudy with mist and drizzle at times, this most extensive over the hills. Bright or sunny spells in the east and very warm. Breezy in far northwest. Maximum temperature 23 °C.

Tonight:

Light rain in the northwest this evening clearing away tonight though the Isles and far northwest staying cloudy. Elsewhere some long clear spells developing. Minimum temperature 11 °C.

Friday:

Dry and mostly very warm or hot with plenty of sunshine. Still more cloud for the Outer Hebrides but this breaking up later. Maximum temperature 26 °C.

Outlook for Saturday to Monday:

The weekend dry with long sunny spells and hot or very hot. Some coastal haar possible in northeast on Sunday, Chance of some thundery rain moving northeast later Monday.

The heatwave from the weekend will be gradually eroded from the west early next week as a cold front arrives from the Atlantic. This will bring the chance of some heavy rain or showers, perhaps thundery, especially in northern and western areas. Towards and beyond midweek, a rather changeable pattern is anticipated with some rain or showers possible at times, which could be heavy and thundery, and particularly focussed in western and northwestern areas. Longer drier spells are most likely towards the south and east, although even here some showers may be possible at times. Temperatures are likely to remain above average, especially in the south and east where further spells of very warm or hot weather remain possible.

A continuation of the broad themes from earlier in the month at first, with high pressure probably dominating the south and lower pressure more favoured to affect the north and northwest. Temperatures are likely to end up above average overall with a continued, and perhaps higher than normal, chance of occasional hot spells or heatwaves, especially further to the southeast. However, around the turn of the month, there is a signal for perhaps more widely unsettled weather to develop, though the details of this remain rather uncertain.
