Long range weather forecast for the Western Isles – 22nd October 2020

Good afternoon and welcome to our long range forecast. This is posted either once or twice a week covering from 4 days ahead to 10 days ahead. In this update coving from Monday 26th October until Wednesday 4th November.

Please note there is not a lot of accuracy for this kind of time frame. Anything beyond 4/5 days out becomes really difficult and subject to change so we will be looking at trends. Mainly take with a large vat of salt. We will be using the main two computer models for this. The ECMWF which is based in Reading and the GFS which is the American based global model.

This comes from the GFS 06z run and ECMWF 00Z run. I will refer to EC to save on typing.

Monday 26th October

After a windy weekend there is some good model agreement that we are going to see winds easing down for a time. We are going to see a mixture of sunshine and showers. Some of these heavy with brisk winds from the North West. Temps in single figures. High pressure builds in with some rain moving in from the West much later.

Tuesday 27th October

A lot of uncertainty. A deep area of low pressure is expected between us and Iceland. The EC is suggesting low pressure below 940 mb to our West and we would see heavy rain and strong winds. The closer the low and the tighter the isobars the stronger the winds. This would likely bring us winds of 50 to 60 mph based on this current track. The GFS on this model runs keeps it further West and keeps it windy for us but the very strongest winds much further out to sea.

Wednesday 28th October

Good model agreement that keeps the deep area of low pressure out to sea. We would see strong and blustery winds across the Western Isles. With winds gusting 40 to 50 mph. Both models show a new area of low pressure. EC has it far West toward the end of the day. The GFS shows the low pressure over Ireland with strong winds and rain.

Thursday 29th October

Again some model differences with the EC suggesting the area of low pressure pushing past the North West of Scotland. Not that deep however we would see some strong winds for a time and showers. The GFS bring the low near Ireland Northwards it would bring rain and strong winds for us for a time. Risk of some snow over higher ground.

Friday 30th October

More differences with the EC suggesting a day of sunshine and showers. With heavy rain moving in later. The GFS suggests a deep area of low pressure moving across England and Wales into the North Sea with. Just some spells of rain for the Western Isles.

Saturday 31st October

Some more model agreement for the last day of October with high pressure building in for a time with some mostly light rain for the the Western Isles on the EC but in the GFS suggests some heavy rain for a time but becoming more settled.

1st, 2nd, 3rd and 4th November

Now this really the long range. So really is take it with a large amount of salt and is the silly range. At this long range the GFS there is some suggestion of two areas of low pressure one to the West of the Western Isles and one in the North sea for the first two days and then a Northerly showery airflow setting up behind.

Thanks for reading any feedback is always welcomed.

Bears Watching

It had been a wet and windy couple of days. We hit 50 mph today. Nothing significant I know but strongest since June.

Now it’s that time of year again. A couple of things to bear watching. Saturday is looking increasingly likely that we could see the first 60 mph of the Autumn/ Winter period with a fairly deep area of low pressure. Heavy rain. There is a slight chance we may see stronger than 60 mph. No warnings have been issued at this stage. But now is the time to get ready. Securing loose objects in the garden and if required touches etc if we lose power.

The second and we have been getting questions about this so wanted to tackle it head on is next Tuesday. A long way off in terms of weather. However various computer models have been showing an extremely low pressure to our North West. Which could bring us some strong winds. However, it’s not worth getting worried about yet just be aware and let’s get Saturday and Sunday our the way with first. The weekend isn’t looking too significant but the first 60 mph plus is worth keeping an eye on.

I will keep you updated as ever.

Thursday’s forecast – A more settled day before it all goes downhill again.

Morning and afternoon – Mainly overcast with some decent spells of sunshine. A few scattered showers around but most places are expected to stay dry. The greatest risk of showers for the Uists and Barra. Winds of 10 to 30 mph.

Met Office rainfall warning and SEPA flood alert for the Western Isles 19 Oct 2020

Good afternoon. This morning the Met Office extended its wet weather warning for rainfall to cover the Western Isles. It is a yellow rainfall warning. The warning came into force in the early hours of this morning and expires at 0900 Tuesday morning.

They are expecting 20 to 40 mm of rainfall to fall widely in the warning area.

For the very latest updates and full warning can be found here https://www.metoffice.gov.uk/weather/warnings-and-advice/uk-warnings#?date=2020-10-19&id=95855521-23c1-4b96-b08a-c1cd950534bf&details

The Scottish Environment Protection Agency has also issued a flood alert for the Western Isles but the main areas of focus are Lewis and Harris.

The full alert and latest updates can be found here https://floodline.sepa.org.uk/floodupdates/info/group-id/4964/

Impacts for the islands

Looking at the two main models this morning the GFS is suggesting 40 to 50 mm widely across the Western Isles till midnight Wednesday from 0600 Monday morning. This is a little bit higher then what the Met Office is suggesting at this stage. The EC model is keeping it between 30 to 40 mm widely with up to 60 mm for Barra. Again 30 to 40 mm it roughly what we would expect and is line with the Met Office thinking however the 60 mm on Barra seems a little on the high side but worth keeping an eye on. This covers from midnight Monday till Midnight Wednesday.

I will keep you updated as things progress any warning updates and I will post rainfall totals later in the day.

Long range weather forecast for the Western Isles – 18th October 2020

Good afternoon and welcome to our long range forecast. This is posted either once or twice a week covering from 4 days ahead to 10 days ahead. In this update coving from Thursday 22nd October until Saturday 31st October.

Please note there is not a lot of accuracy for this kind of time frame. Anything beyond 4/5 days out becomes really difficult and subject to change so we will be looking at trends. Mainly take with a large vat of salt. We will be using the main two computer models for this. The ECMWF which is based in Reading and the GFS which is the American based global model.

This comes from the GFS 06z run and ECMWF 00Z run. I will refer to EC to save on typing.

Thursday 22nd October

Good model agreement with regards to Thursday. After a wet start to the week Thursday is expected to be a more settled. High pressure in charge. Rain moving in much later in the day. Overcast day with mainly light winds with stronger winds into the late evening. Its expected to be a cooler day.

Friday 23rd October

Again good model agreement with showers and blustery winds. Brisk winds with a strong South Westerly airflow. Some sunshine. Temps in low double figures and an area of low pressure building out West.

Saturday 24th October

There is some computer model agreement about a deep area of low pressure moving to the North West of Scotland. The GFS brings the low pressure closer to the Western Isles then the EC and would see strong winds gusting 40 to 50 mph with some hints of 60 to 70 mph for the Uists and Barra. This is a LONG way off yet and worth keeping an eye on at this stage. The EC suggests the low would be further West and thus reducing this risk of us seeing stronger winds. So at this stage we are again looking at trends and to see if computer models continue to show this area of low pressure forming and bringing it close to us. I will keep an eye on it closely and keep you updated if required.

Sunday 25th October

Good model agreement that would suggest that the area of low pressure would move away. The GFS suggests that we would see more in the way of rain and breezy conditions. The EC suggests less in the way of rain. Mainly high pressure across the UK.

Monday 26th October

Some model disagreement for the 26th October. The GFS suggests strong winds with heavy rain moving into the Western Isles. Winds gusting above 40 mph. The EC suggests brisk winds with high pressure across the UK but keeping things dry across the Western Isles.

Tuesday 27th October

Again more model disagreement the GFS suggests more of an unsettled airflow with brisk winds and more in the way of rain. The EC again suggest brisk winds and dry conditions with high pressure across the UK.

28th, 29th, 30th and 31st October

Now this really the long range. So really is take it with a large amount of salt and is the silly range. At this long range the GFS suggests an unsettled theme for the Western Isles. It also shows a deep area of low pressure across Ireland and into England and then South East Scotland. Again a long way off yet.

Thanks for reading any feedback is always welcomed.

Met Office Warnings for South West Scotland 19/20th October.

Good afternoon the Met Office has issued a yellow weather warning for parts of South West Scotland on Monday and Tuesday. This comes as no surprise as this was forecast for a good few days now. NO weather warnings have been issued at this stage for the Western Isles. However I will mention possible impacts for the Western Isles below.

Here is the full warning from the Met Office – The warning comes into force at 0300 Monday morning and expires at 0900 Tuesday morning.

Here is the text to go alongside the warning and impact scale

The full warning and latest updates can be found here https://www.metoffice.gov.uk/weather/warnings-and-advice/uk-warnings#?date=2020-10-19&id=95855521-23c1-4b96-b08a-c1cd950534bf&details

Western Isles

As mentioned above no weather warnings have been issued for us at this stage. I will update the page if any warnings do get issued.

The 06z run of the GFS model is suggesting anywhere from 40 to 50 mm of rainfall for the Western Isles from 0600 this morning till midnight Wednesday. Whilst the 00z run of the Euro model is suggesting 30 to 40 mm for the Western Isles. This covers from Midnight Sunday till Midnight Wednesday.

30 to 40 mph winds are also likely but are down from the 50 mph we were expecting to see a few days ago. Coming from the North and North East would likely cause some ferry disruption.
