Friday’s low pressure brings strong winds and heavy rain

Many areas are still calling for rain after many dry months. Western areas will see heavy rains in a relatively short time, which could lead to localized flooding in prone locations or large puddles. 20-50mm of rain is likely, or 1-2 inches in just a few hours.

A stronger jet will cross the North Atlantic directly and it is the left exit area of ​​this jet core that will develop Friday’s low. There will be further deepening early on Friday, but there are only slight differences in timings for different models around the progress of the rain band across Britain.

Friday will start cold for parts of Britain. Much of England and Wales will have light winds, clear skies, but with mist and fog forming due to low temperatures in the first place. It will be quite a change by the end of the day. The Western Isles will see gales from the south through the night as the rain settles in, then strong gales with gusts over 70mph to start on Friday. Minch Coastal Waters mentions “possibly an increase in Storm Force 10”.

There are already warnings that ferry services to the west coast of Scotland could see disruption and it will be a wet and windy start here and also for Northern Ireland. Precautions will be required around exposed coasts and on high ground as wind speeds increase and strong gusts continue. As the heavy frontal rain passes, the southerly winds will veer to the west.

Around noon, the Northern Isles will see gales from the south, even strong gales with gusts over 70 mph. It will be very windy across the Irish Sea, again with possible impacts on ferry services and very wet and windy for the Solway Firth, Isle of Man, Cumbria, Dumfries and Galloway and Gwynedd towards lunch time. Winds will be strong SSW reaching gale force over exposed coasts and hills. Aberdeen will be windy in the afternoon as the front clears. This leaves brighter skies for much of Scotland and Northern Ireland in the afternoon, but with a rash of heavy showers blowing in the brisk westerly wind.

The weather deteriorates over much of England and Wales during the afternoon with a moderate to cool south-westerly wind. There will be gusts of 50-60 mph for exposed coasts and hills with clearing Kent at midnight.

It’s not a hugely disruptive weather event, not a named storm, but it certainly looks wild in the far northwest to start Friday. And yet, it will be the beginning of a progression, no doubt, of fall lows and seasonal wet and windy weather. People might have Friday travel plans, especially for Friday night, so the advisories are a warning that there could be impacts from this wet and windy period. However, it progresses steadily from NW to SE before the weekend. It’s not related to Hurricane Ian, which remains over the continental United States.
