7 days in Weather – 29th March

Hello and welcome to the first 7 days in weather. In this new series of blogs we a take a look back at the last 7 days of weather across the Island,  UK and across the globe.

UK Weather:

Wet Week for the North West

Its has been a high pressure dominated week for much of the UK. We had the highest temperature of the year so far in Rhyl 19.4C

A little closer to home a wet start to the week with rainfall warning during Monday, Tuesday and early Wednesday that covered the Western isles.

Here are the rainfall totals from the two days from the SEPA rain gauges in the Western Isles.

Birkie Hue – 75 mm

Creed Bridge 43.8 mm

Laxdale Harris 111.2mm

Loch Tormasad – 67.2mm

Mill croft – 57.4mm

We have seen far worse rainfall events and as far as I am aware this didn’t cause any flooding. I did not see any photos or reports of flooding.

on Skye, Allt Dearg House recorded a whooping 222mm of rainfall across the two days.

High pressure.

This week has seen high pressure dominating the weather across the UK. This weekend high pressure became firmly in control to the North West with the March high pressure record being broken. More from the Met Office below.

Global weather – USA

We are now entering the peak months of Tornadoes in the USA. I tend to go out storm chasing Mid May. Tornadoes can occur at any time of the year but the peak months are normally during March, April and May for the USA.

Nashville Tennessee had a series of tornadoes at the start of the March. Yesterday was the turn of Arkansas and the last couple of days also saw massive hailstones In Oklahoma.

Above is BBC online showing the Arkansas tornado.

The recent tornado events have raised interesting questions about tornado shelters with the ongoing global Pandemic.

This article by the capital weather gang highlights this debate.

Weather Blog

Good afternoon all. We are dropping a weather blog post. Quite a lot of weather has happened in the last few weeks and months. No forecast is included in this post. If you need to see a forecast check the Met Office website or app.

Storm Brendan 

Impacted the Western isles on the 13/14th of January. Brought strong winds and heavy rain. In addition, flooding was also a massive impact. Some of the worst coastal flooding that the island has suffered and at least since I have been running Western Isles Weather. Schools were closed and power cuts also occurred widely. Roads were closed by the Emergency services across the island chain.

87 mph was recorded at the South Uist range.

64 mph was recorded at Stornoway Airport

A few more images from around the islands and graphic of wind speeds.

Unofficially wind speed in excess off 90 mph were recorded at some none Met office sites on the Uists and West coast of Lewis.

Wet Winter 

Its been an extremely wet winter across the UK. Extreme flooding across parts of England, Wales and Scotland. So wet the Met Office had to introduce a new level on the scale with 400% on the chart below.

For the UK it was the 5th wettest winter. It was the 5th Wettest winter since records began.  These records stretch back to 1862. For Scotland it was the second wettest on record, the wettest being 1990.

Other storms impacted the UK over the winter. However, storm Brendan was the most disruptive for the Western isles. It has been a very wet and windy winter but may of the storms stayed under 80 mph. Multiple days of wind speeds over 70 mph.
