ALT A close-up photograph of a vibrant red poppy flower in sharp focus, standing in a field filled with blurred red poppies. The sun is low on the horizon, casting a warm golden-orange glow across the scene. Soft sunlight shines through the delicate petals of the central poppy, highlighting their texture and translucency. The background features a dreamy, out-of-focus landscape with rich shades of red, orange, and gold, creating a tranquil sunset atmosphere.
As we head towards the end of this week, we are going to see a brief spell of chilly northerly winds temporarily bringing colder temperatures to a large portion of the UK, giving air frosts for almost everyone at some point in the week.

Heading towards the end of this week, some northerly air will make it noticeably colder and frosts are likely on both Thursday into Friday (Image 1) and Friday into Saturday (Image 2).
Snow is possible on the hills and mountains of Scotland, maybe a bit lower in some spots.
A scan of the MIDAS archive suggests that Heathrow's 10-metre visibility reading at 23 UTC last night is the lowest since automatic sensors took hold and the lowest literal reading of 10 m since Dec 1962; 15th Dec 1991 had <50 m visibility. QC'ing these is a bit of a nightmare!
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 📉

7:00am CST #SPC Day1 Outlook Enhanced Risk: across north-central Oklahoma and south-central Kansas spc.noaa.gov/products/outloo…
Looking at current visibility reports, shown here in m via weatherobs.com, you can see already the extent of dense fog across southern and central England, and areas of wales.
For the third day running, A yellow fog warning has been issued by the Met Office. Take care on the roads tomorrow morning as fog may be dense.
A Major SSW is expected next week. While SSWs boost the potential for blocked patterns and colder weather, any surface effects wouldn't hit until late Nov/early Dec. Since this will be the earliest Major SSW on record, whether impacts definitely occur is uncertain at this stage.

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...
