A day of rain and showers is likely with some sunny spells. Winds of 20 to 30 mph. Temps of 10C to 17C

Have a great evening.

Good evening Western Isles just a heads up that there will be no evening forecast on Sunday or Monday morning but we will be back to normal on Monday evening.

On this Sunday evening, we are seeing frequent rain and showers with some sunshine. These showers are heavy in places.

Today a small area of low pressure brought winds of 56 mph to South Uist range and 46 mph at Stornoway and this is highlighted on the image below from Roost Weather

It looked impressive on Radar as well. As shown on radar below from Netweather.tv. It was a fast developing system. If it had been quicker in deepening and slower moving then it could have caused us a few issues. The South Uist Met Office site also recorded 10.6 mm of rainfall from this system.

Sunday

For Sunday the weather system that brought the wind and rain for Saturday clears away to sunshine and cloud and more settled day as shown on the surface pressure chart below

Overnight – Clear skies and cloud with some scattered showers. A mixture of clear skies and cloud. Winds of 10 to 30 mph.

Good evening Western Isles. Sorry for the later update this evening. A number of technical issues with my Word press account tonight and laptop problems. Hopefully resolved now.

On this Friday evening, we are seeing plenty of cloud. With spells of rain and drizzle. Some clear skies. Winds gusting 30 mph and today’s high of 16.3C

Saturday

So as been talking about most of the week we are going to see some blustery winds overnight and some heavy rain. The Met Office tweeted about blustery winds overnight. I struggle with the term strong winds for wind speeds less than 50 mph but it is classed as gale force.

Turning windy across parts of the north and northwest during Saturday with a risk of coastal gales affecting the Western Isles for a time 🌬️ pic.twitter.com/Xpv41LSr3j

— Met Office (@metoffice) August 19, 2022

We are also going to see some heavy rain with up to 20 mm of rainfall falling in some locations. This is all moving across the island courtesy of a developing area of low pressure. Below is a rainfall accumulation map from WX chart with rainfall to midnight on Sunday

Overnight – We will see heavy and slow moving rain pushing across the islands. This will be persistent in places. Overcast with winds gusting 20 to 40 mph with some gusts reaching 50 mph during the early hours of Saturday morning. We have a slight chance of some of these showers being thundery in nature.

Morning and afternoon – Frequent heavy rain and showers which will at times merge into some longer spells of rain. Some of the showers will be thundery at times. In between some decent spells of sunshine. Winds of 20 to 40 mph.

Evening – Little change with further frequent rain and showers heavy at times. Again some longer spells of rain. In the breaks in the cloud some sunshine. Winds of 10 to 30 mph gusting 40 mph.

After the rain and drizzle cleared this morning we got some decent and at times prolonged sunshine. Showers have started to push in this evening. Visibility was poor at times one of the main features of this summer.

Friday

Low pressure is dominating our weather across the islands at the moment. Low pressure by midday on Friday will be close by to Iceland with weather fronts across the UK. This is a broad area of low pressure so the isobars are not tightly together so winds aren’t too strong. Below is the Met Office chart for Friday

Overnight – Clear skies and cloud with some rain and showers these will be heavy at times. Winds of 20 to 40 mph.

Morning and afternoon – Frequent showers heavy at times. Some of these merging into some longer spells of rain at times. In between the showers in the breaks in the cloud we will see some decent and prolonged sunshine. Winds of 20 to 40 mph.

Evening – Again further showers heavy at times. Some sunshine and then clear skies after sunset. Winds of 20 to 40 mph.

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

Outlook

Saturday – A shallow area of low pressure will bring heavy rain overnight Saturday into Sunday with some parts of Lewis and Harris seeing up to 10 to 15 mm in rain in a couple of hours. Below is the WX chart for 6am Saturday morning.

So we will see heavy overnight rain across the islands during Saturday morning. Then once the rain clears away again it will be sunshine and showers. Winds of 20 to 40 mph. Temps of 11C to 15C

Sunday – Sunshine and cloud with winds easing under 20 mph. Temps of 10C to 16C

It was a cold start to the day for Lewis and Harris with 4.7C being recorded at Stornoway Airport. Stornoway was in the bottom 10 of cold temperature for overnight Tuesday into Wednesday. The image below is from Roost Weather showing the overnight minimums.

The temperature jumped from 5.2C to 11C between 6 and 7 am this morning. Again the image below comes from Roost Weather

Winds will be from the South West and temps of 11C of 18C

Sunrise and Sunset

Stornoway – 05:54 and 21:04

South Uist – 06:01 and 21:05

Outlook

Low pressure will drive our weather across the islands over the weekend. We will also see brisk winds.

Friday – We are going to see spells of rain and showers heavy at times. Some decent sunny spells in between. Winds of 20 to 40 mph from the South West. Temps of 11C to 17C

It was a cooler day across the islands today. Drier and brighter once the morning rain cleared away allowing for some sunshine.

Wednesday

High pressure is firmly in control on Wednesday which will give us a mostly settled day but there is a broad area of low pressure awaiting out West which will become a dominant feature of our end of the week weather.

Overnight – Clear skies and cloud. Under these clear skies, we will see temperatures drop into single figures. Winds under 20 mph.

The Met Office model, as shown in the image below, indicates temperatures could get as low as 5C.

Morning – A mixture of sunshine and cloud some decent and prolonged sunshine with variable amounts of cloud. Winds under 20 mph.

Afternoon and evening – The cloud is expected to build back in with some sunny spells. Occasional scattered showers and some rain but for most staying largely dry. Winds of 10 to 30 mph.

Sunrise and Sunset

Stornoway – 05:51 and 21:07

South Uist – 05:59 and 21:05

Outlook

Thursday and Friday – Sunshine and showers with brisk wind. The showers heavy at times. In between some decent spells of sunshine. Winds of 20 to 40 mph.

Saturday

Has got my attention. The computer models have been hinting at a low pressure system forming close to the Westen Isles overnight Friday into Saturday. There is a lot of uncertainty as yet . The consistent part of is that we are seeing plenty of rain being shown by the models on each run but not so much the area of low pressure. The GFS had the low pressure on the 18z model run last night but has backed off on it since. The EC is showing the area of low pressure this evening and as is the Met Office model the UKV.

If what is being shown by the EC we could see some heavy rainfall in a short period of time with winds gusting 40 to 50 mph. The image below from WX charts shows the low pressure below. Remember this is just one model run. But I will be keeping an eye on it.

So at the moment, I am expecting to see overnight heavy rain and persistent rain with sunshine and showers during the rest of the day. Winds of 20 to 40 mph and temps of 11C to 15C

Sunday – A mostly fine and dry day with a few scattered showers plenty of cloud. Winds under 20 mph. Temps of 11C to 16C

Have a great evening

Good evening Western Isles on this Monday evening we are seeing a mixture of clear skies and cloud. Winds under 20 mph and today’s high of 15.2C

Mist and low cloud once again caused issues with ferry delays and cancellations today along with Plane delays and cancellations. This is one of the worst summers I can remember for Mist and Fog we always get spells of it during the summer months but I don’t remember it being this frequent.

Tuesday

For Tuesday high pressure starts to build in behind the cold front that is slowly moving across from the West Coast of Scotland. As shown by the Met Office chart below.

Overnight – Some rain and drizzle with some mist and low cloud. Increasing amounts of clear skies. Winds of 10 to 30 mph.

Morning and afternoon – Some lingering mist and fog should clear away. Increasing sunshine with some scattered heavy showers. Some decent and prolonged afternoon sunshine. Winds of 10 to 30 mph.

Evening – Most of the showers will clear away a few well scattered showers in places. For most a fine and dry end to the day with variable amounts of cloud and decent and prolonged sunshine. Winds of 10 to

30 mph.

Winds will be from the North and Temps of 8C to 14C

Sunrise and Sunset

Stornoway – 05:49 and 21:09

South Uist – 05:57 and 21:10

Outlook

The mid to end of this week and the weather is going to turn more like Autumn and when I say that stronger winds and spells of rain with areas of low pressure moving across the islands as opposed to settled misty and overcast conditions.

Wednesday – Sunshine and cloud with light winds until the evening which will gust 30 mph later. Winds of 10 to 30 mph and temps of 12C to 15C

Thursday

You can see the low pressure system that will bring more unsettled weather on Thursday across the islands. This image comes from WX Charts and the EC Model 12z run.

will be a day of sunshine and showers and brisk winds. Winds of 10 to 30 mph with some gusts reaching 40 mph. Temps of 12C to 18C

Friday – Again sunshine and showers these will be heavy at times. Some decent spells of sunshine. Winds of 20 to 40 mph. Temps of 10C to 15C

Saturday and Sunday – More of the same with sunshine and showers along with brisk winds. Winds of 20 to 40 mph from the South and South West. Temps of 10C to 16C

Have a great evening

Good evening Western Isles on this Sunday evening we are seeing sunshine and cloud with some mist and low cloud. Winds under 20 mph and today’s high of 16.6C

Thunderstorms and heavy rain have impacted large parts of Scotland today. The Western Isles missed out on the storms as they went East of us. It has caused flooding in Inverness. Here is a map below showing the track of the storms from Netweather

Monday

We are once again outside the Met Office weather warnings for Thunderstorms on Monday which will be over Southern of the UK. Weather fronts still sit close to the Western Isles as highlighted by this Met Office pressure chart.

Morning and afternoon – Staying mostly cloudy with some light rain and drizzle with a few scattered showers which could be thyndery at times.. The cloud breaking at times with occasional sunshine. Lingering and slow to clear mist and fog. Winds under 20 mph.

Thunderstorm warnings

So the Met Office issued several thunderstorm warnings for Sunday and Monday earlier today. These cover a large part of the UK but don’t cover the Western Isles. At this stage, the very worst will be over the mainland. But just because we aren’t in a thunderstorm doesn’t mean that our risk is zero. It can mean one of two things that the impacts of any storms for us are too low for a warning or the thunderstorms are likely to miss us. The greatest risk at the moment for us seeing thundery showers would be Sunday into Monday. But again stressing the point that there is a lot of uncertainty at this stage and I will keep you updated. This is one of the main things about doing these more in depth forecasts is to have the ability away from the shorter form forecasts to go into more detail to talk about the weather and warnings.

I will watch with interest how the forecast evolves in the coming days and how the Met Office amended its warnings and I will keep you updated. Below is the warning for thunderstorms that covers Scotland.

Good evening Western Isles. That was another dull and damp day with mist and low cloud a plenty. We are currently seeing plenty of cloud with some rain and drizzle. Heavy in places with mist and low cloud. A few sunny spells. Winds under 20 mph.

One thing I did note from today was the rise in visibility at Stornoway Airport from 1,800 meters to 27,000m from the 15:00 reading to the 16:00 reading. With the wind direction shifting to come in from the North.

Friday

Once again we are in a rut. A warm front sits close by to the Western Isles. Again we will see plenty of cloud mist and drizzle. Met Office surface pressure chart below.

Overnight – A cloud dominating night with spells of rain and drizzle with some mist and low cloud. Winds under 20 mph.
