The Meridional Overturning Circulation and the Hadley Cells and the Rossby Waves, are all doing very well indeed. It is often a case that High Pressure from the SE, South and SW often controls our weather sequence we have to wait until mid December that is when the Azores High weakens.
So much High Pressure And so much cold pooling but for the UK we end up just checking the ducks are able to wander around and we carry on not seeing any exceptional cold snowy weather.
N. Ireland, Wales and N England plus Scotland will have to wait until we get to Mid-November et all this Autumn to imagine any chance of winter weather coming into the 3-5 day range.
I keep checking the charts, Greenland and the NE Canada and Arctic Svalbard and Iceland to Central Norwegian Sea has been often seeing numerous cold and wintry Low Pressures and cold pooling, Semi-Polar Vortex setting up in last few weeks, this cold air gets to Iceland and persists in N and NE Canada and Greenland a lot, and the Mid Lattitude High’s are often locates in West and NW Atlantic as well as across SW South Central UK West Europe, with N and NE N Europe away from the UK currently expected to see a very cold Low Pressure NNW SE cold flow of cold arctic Sea air migrating to East and NE and N Central Europe. But Milder weather returns to West and N Central Europe as Low Pressure moves east on Wednesday Thursday from Iceland through North Sea and Low Countries and Denmark NW Germany.
Climate is warming up, Scotland and N Ireland and North England still often gets some Winter frost, ice and snow, November to March, but the SE and South UK including S Central England and Wales, together with the West and North through the year, they sometimes get more rain than London and S SE England, where some longer dry fine spells without much heavy rain is seen every year.
The North Atlantic Sea often gets some much Colder Wintry conditions from November to March Months, and Mild SW and South winds tend to be more frequent over the East and SE of North Atlantic Sea, as the Azores High tends to stay in charge.Â
With this warmth and heat, the Central and South UK has become mostly free of snow and frost.
