Very dangerous conditions out there near Heathrow. You can barely see the road from this traffic camera - imagine driving in this!
Extremely dense fog ongoing: Heathrow airport has also now reported a visibility of just 10 meters. Google Maps suggests multiple crashes have occurred near the area due to this localised extremely dense fog, with absolutely awful traffic conditions.
Some extremely dense fog developing in some areas. Visibility of just 10 meters has been reported in Northolt.
Furthermore, fog is starting to develop in areas of SW Northern Ireland. The Met Office have just issued a yellow warning to cover that threat.
Fog is starting to develop across the country as for the third night in a row a Yellow Fog Warning is in force.
The map to the left shows observed visibility in meters.

Let me save you all some article reading time...
Will the earliest weakening of the polar vortex on record bring snow to the UK?
Nobody knows.
THE END.

Largely clear skies across England & Wales gave a unique chance to study the temperature response to the 12th Aug 2026 solar eclipse — a rare evening eclipse ☀️🌗🌍
Screen temp reached a mean anomaly of –1.8°C ~16 mins after max eclipse 📉

Oh come on GFS, 12 November is too early for snow in SE England 😆
The model has been hinting at much colder air spreading south into the 2nd week of November over recent operational runs, though they have been cold outliers in the ensembles.
Very much depends on where the blocking high migrates...

On Sun 29 March 2026, damaging winds occurred in South Yorks and Lincs associated with shallow convection just 3–4 km deep. Radial velocities of up to ~80mph were detected.
The event has been published as a Spotlight article in @RMetS journal "Weather": rmets.onlinelibrary.wiley.co…
Fun fact: under the current met office system, a Red weather warning for fog is impossible and can't be issued.
This is because there are no extreme impacts listed on impact tables, needed for a red warning.

ECM zonals are now going for a reversal of winds AKA: Sudden stratospheric warming achieved. Also a slower recovery.
Watch out for the end of November and early December... 👀👀
