Friday 15th July Weather forecast for the Western Isles.

Good evening Western Isles on this Thursday evening we are seeing plenty of cloud with some clear skies. Some scattered showers. Winds under 20 mph and today’s high of 16C

It was a rather quiet day across our islands weather wise and this time of year the weather tends to be more slow paced. I will have more mid month weather stats in the coming days.

Friday

Overnight – Plenty of cloud with some rain and drizzle across Uist and Barra this will be heavy at times. Scattered showers for Lewis and Harris with plenty of cloud. Winds under 20 mph.

Morning – Plenty of sunshine. Feeling warm in the sunshine. Still plenty of stubborn cloud which will be slow to break. A few scattered spells of rain and showers but for most staying dry. Winds under 20 mph.

Afternoon and evening – Sunshine and cloud. But cloud thickens in. Some patchy rain and drizzle. Not all will see rain with most places staying dry. Winds under 20 mph.

Winds will be from the West and North West. Temps of 11C to 17C

Saturday – An overcast day with some patchy rain and drizzle. Some sunshine mainly hazy. Feeling warm but noticeably windy gusting 20 to 40 mph. Some gusts could be stronger along Western coasts as highlighted in this image. Winds will be from the South West. Temps of 11C to 17C

Sunday and Monday – The cloud will dominate with some sunshine at times especially later on Monday. Some patchy rain and drizzle. Winds will be from the South and South West under 20 mph. Temps of 11C to 18C

Tuesday – Could well be our hottest day of the year. A day of sunshine and cloud mainly dry. Winds under 20 mph. Temps of 11C to 21C. A long way off as yet but will keep you updated.

Some computer models are hinting that we could see 21/22C on Tuesday next week which would be 3 or 4C higher than anything we have seen so far this year. The chart I am sharing below shows a possible 40C for parts of England on Tuesday. It might not get that high but we could see a risk of 38.7C falling the current UK record. You don’t see 40C on a chart every day.

Have a great evening.
