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!

Multiple crashes on the M4 have occurred, and you can't be surprised in these extremely dense foggy conditions. Here you can just make out a vehicle by their lights.
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.

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.

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.

Fog, dense in places, is expected to again develop tonight into tomorrow morning...

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...
