Long range weather forecast for the Western Isles – 22nd November 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 26th November until Saturday 5th December.

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 26th November

Good model agreement with regards to next Thursday with high pressure in control across the UK. For us in the Western Isles we are going to se blustery winds. A dry start with the EC suggesting light rain moving in later in the day. The GFS keps the dry day. It would be a chilly day. The EC has high pressure centred over the North East of England and the GFS has it centered over Wales.

Friday 27th November

Some slight model disagreements here. Both the GFS and the EC has the high pressure system declining back into Europe. The EC keeps a band of rain out in the Atlantic and mainly dry for us in the Western Isles. However the GFS brings the band of rain across the Western Isles with a showery airflow behind it.

Saturday 28th November

Model disagreements again for next Saturday with the EC again keeping us mainly dry and with light winds. A slack airflow across the UK. The GFS introduces further spells of rain and strengthening winds which would bring gales. High pressure to the East of the UK and low pressure to the South West in this instance.

Sunday 29th November

Now both models develop an area of low pressure that would be run up from the Irish Sea. This would bring heavy snow into the highlands of Scotland. However the GFS builds in a shallow area of high pressure over Scotland. The EC does no. Both these scenarios would bring patchy rain and showers to the Western Isles and it would be breezy.

Monday 30th November

Model disagreements on this date with the EC bringing a dry start to the day for the Western Isles before rain and stronger winds would move in later in the day. The GFS on the other hand builds in the high pressure in further. Keeping things fine and dry with a mixture of sunshine and cloud with lighter winds.

Tuesday 1st December

Further model disagreements as we move into December. The EC develops two areas of low pressure that would bring wet and windy weather to the Western Isles with gales. The GFS keeps high pressure centred over the East coast of Scotland. This would mean fine dry and sunny weather for the Western Isles with light winds.

2nd, 3rd, 4th and 5th December

Now this is the really long range. So take it with a large amount of salt and is the silly range. The GFS keeps things settled across the Islands. A chance of some rain towards the end of the time period but nothing to extreme. No storms on the horizon.

Thanks for reading any feedback is always welcomed.

Let it snow…..

Hello and welcome to this blog about snow. There is no snow in the forecast for the Western Isles for any time in the near future. But I am getting a lot of questions about when we are going to get snow and are we going to get a white Christmas.

How does snow form

First place we start is how does snow form with this video from the Met Office.

In the Western Isles

Here in the Western Isles we don’t often get huge amounts of snow. Most winters we will get 2/3 “snow days’. This is where snow sticks on the ground and lasts more than a couple of hours. Quite often it quickly melts away.

Years like 2009/10 are quite rare we don’t usually get long spells of snow. Other notable snowy winter where 1995 and 1991 in the last 30 years.

In December on average the UK sees 3.9 snow days. 5.3 days in January and 5.6 days in February. With March seeing 4.2 days according to the Met Office. So you more likely to see snow in March then December.

The Western Isles covered in snow from BBC News in 2010.

So why is so hard to forecast snow?

The Met Office explains all –

Why is snow forecasting in the UK difficult?

As it’s so cold high up in the atmosphere, most precipitation either starts off as snow or supercooled raindrops. As it falls to earth, it moves through warmer air most of the time and melts. Depending on the temperature of the air near the ground we either see rain or sleet or hail. However, the freezing level (usually the boundary at which precipitation will fall as snow rather than rain) doesn’t just stay the same every day, or even within a day, sometimes it can change hour by hour, across the country, or even a few miles down the road. 

There are several things forecasters look at to predict how low down the precipitation will fall as snow:

  1. Where the air has come from – if the air has come from a slightly different direction, say for example if it has spent a slightly longer time travelling over mild water, then the air can be ever so slightly warmer, and therefore the freezing level would be slightly higher up.
  2. Very heavy precipitation – Even if the freezing level is quite high up in the air, it turns out that really intense precipitation can drag the “freezing level” nearer to the ground, and keep any precipitation falling as snow lower down too. Prolonged, heavy rainfall can therefore turn to snow.
  3. When warm air meets cold air – this is the most difficult situation to predict snow. Weather fronts mark the boundary between cold air and warm air, so when a weather system moves in, there will be warm air and moisture wrapped up in it. While we need the moisture for snow to form, the warm air makes it very tricky to forecast if it will be turning to rain. As the warm air bumps into the cold air, it slides up over the top (warm air rises). The precipitation falls into the colder air lower down, but in time the air mixes together and makes the cold air slightly warmer, and the warm air slightly colder, and so then rain becomes more likely. You’ll often find that there’s a fine line between who sees snow and who sees rain. Sometimes a fraction of a degree is the difference between rain and snow. That’s what makes forecasting snow difficult (and often frustrating!).

Avoiding clickbait and crap apps.

So did you see the headline of the blog and click on it without reading the description first? See this how clickbait headlines work and they entice you in. Weather stories and ones about snow are some of the most clickable stories. Hence why the Daily Express churns them out. Yeah I am still awaiting the 300 days of snow they promised a few year back. The articles tend to have grains of truth in them but the are mainly just huge amounts of hype. It is best to avoid anything about snow from newspapers or news sites. They more you click the more you fund there advertisement revenue.

Watch out for the so called crap app. These are mobile phone apps such as XC Weather or the iphone weather app. These are called crap apps because they just indgest weather data with no human input. So you are seeing raw model data without the human input that understand the differences and they local variations of the forecast.

For example a few years ago 20CM of snow was forecast for several days by XC Weather in Stornoway. It that did happen I would struggle to stand in Stornoway Town Centre. I stood there in the rain with zero snow falling and zero snow had fallen that day. Yet people take this as gospel.

So where are good places to get snow forecasts. Because it’s so difficult to forecast more than a day of two out anything further then that is probably pushing it for accuracy. I will let you know if there is a snow risk on my updates. Met Office warnings, text forecasts and press releases are another good place to look. Netweather have in the past done good blog posts on the subject of snow as well.

White Christmas 2020

Will we see a white christmas this year is a question I get a lot. It is far too early to know yet by a long shot. Our first White Christmas forecast will be issued on the 1st of December so look out for that.

We can’t end a conversation about snow without a time lapse video of snow from the USA

I hope you have enjoyed this blog update any feedback is welcome.

Kelvin-Helmholtz cloud

In this extra special blog we are going to talk about Kelvin-Helmholtz cloud. This blog has been inspired by the photo shared to us this morning by Ed Lewis. Who captured some Kelvin-Helmholtz clouds this morning on the Isle of Lewis.

So what is Kelvin-Helmholtz cloud?

According to the Met Office they are “an extremely rare phenomenon, where a cloud produces a billowing wave pattern. They occur when there is a strong vertical shear between two air streams, causing winds to blow faster at the upper level than at the lower levels.”

Another example of this Ireland earlier this year

Who discovered them?

“Kelvin-Helmholtz clouds are named for Lord Kelvin and Hermann von Helmholtz, who studied the physics of the instability that leads to this type of cloud formation.”
