Could we see a brutally cold easterly this January?

It's notable that the upcoming Atlantic spell is more of a weak zonal flow, rather than something much stronger

As a result, pressure in the Arctic isn't looking all that low, especially in Barents Sea area. The low-pressure systems that push through the Atlantic may manage to pull some warmer air over that area to generate a weak Arctic High when combined with the leftovers of the current diminishing Greenland high. While that by itself isn't all too helpful to cause cold spells, if that signal on the chart above were to trend south, which isn't very unlikely, considering that it's at day 10, brutally cold air could build to our east, while the jet stream undercuts it, allowing this frigid air to make its way over us.

Take this GEFS member for example, considering that this is very cherry picked, and it isn't a trend at all in the ensembles

In addition, teleconnections are supportive of a Scandinavian high in late January

The Impacts of an AMOC collapse on Europe

The impacts of an AMOC collapse on Europe Introduction As the Earth has warmed, one section of the Atlantic Ocean has been cooling. This has been attributed to an ocean current, known as the Atlantic Meridional Overturning Circulation (AMOC) weakening. This ocean current regulates the climate worldwide by transporting waters at different temperatures, but this is expected to continue to weaken with climate change, bringing worrying consequences on the climate. However, a more extreme, but still a very plausible scenario of the current collapsing may occur as early as mid-century, where the climate may rapidly change within a few decades. In this summary, I'll focus on Europe. Source: High-resolution ‘fingerprint’ images reveal a weakening Atlantic Ocean circulation (AMOC) The AMOC brings warmer water from the Gulf of Mexico to Europe, contributing to keeping its climate mild in comparison to areas such as Canada. Under a collapse, a lot of the warmer water is shut off, shown by the...

Long range UK weather forecast: 8th February 2026

Image
First, let's look at the main factors at play. Current situation Lack of a clear tropospheric polar vortex Higher pressure over Greenland, but not strong enough to have a big influence aside from weakening the Atlantic storm track High pressure over Scandinavian snow cover, trapping cold air that forces the Atlantic storm track to weaken and shift south as it moves west, into the UK Active Atlantic storm track, albeit weaker on the eastern side as it passes over the UK As a result, you have a weak zonal flow dominating the UK, causing rain, as well as more settled weather between low pressure systems. The lack of jet stream amplification keeps temperatures close to average. Mid-range model output On Monday to Wednesday, pressure over Scandinavia is reduced, strengthening the storm track. It creates wetter and slightly milder conditions On the rest of the week, cold air in Scandinavia and Siberia mixes with the Atlantic storm track. In the north of the UK, there's more influence...

Cold spell inbound for the UK? Can we see more cold in early and mid Febuary?

Image
This weekend and into next week, high pressure over Scandinavia will draw in cold air into Europe, and also block and push the jet stream south, allowing this cold air to move over the UK, starting with the north. For the northeast of the UK, this easterly winds over the North Sea may stir up some snow showers under low temperatures. For the south, things look more uncertain, but temperatures will be below average, with risks of rain and snow Past this point, may we see further cold spells?  First of all, the EC46 suggests this, but at the same time, it does very often overestimate the risks of weather patterns that tend to bring cold weather to the UK. High pressure north of us blocks westerlies and forces the jet stream south, which can lead to cold air from the north, east or northeast filling in the gap Notice the high pressure to our north and low pressure to our south? That's a clear NAO- pattern here. Both the GEFS and CFS are on board with the NAO- being negative till mid-F...
