Air pressure for winter 2025/26 in northeast Fife as recorded by my Aranet4 sensor (~10m amsl).

Dominantly cyclonic, except for a long-lived anticyclonic spell between Christmas and New Year. Particularly dire between mid-Jan and mid-Feb when we barely scraped 1000 hPa.

We’re connected on LinkedIn. Does Jens run weatheriscool? I must admit I didn’t know who wasn’t behind that site.

It’s a close one. Charlton & Polvani 2007 definition: β€œcases where the zonal mean zonal winds become easterly but do not return to westerly for at least 10 consecutive days before 30 April are assumed to be final warmings”

I’m aware my website seems to be down, which seems to be problem at the hosting end (Wordpress). A bit tied up with teaching today, so hoping it fixes itself (I know many of you just can’t live without knowing the latest regimes forecasts πŸ˜‰)

Finally a movie about the stress of meteorologists trying to convince decision-makers to change their plans based on a weather forecast.

The movie focuses on British meteorologist James Stagg and the pressure he felt leading up to the D-Day invasion.

You also have to scroll down past the temperatures anyway to get to this bar thing, so it’s redundant

Agreed

I agree. The bars really don’t tell you anything that the numbers don’t. And the fact that the scale needed an explanation here means it’s not something easily deduced (unless I’m just stupid)

Any clarification on this? It hasn’t changed since the first version of this new app and has been baffling many people, not just me. bsky.app/profile/simo...

Wow! I don’t use the widget and don’t seem to have had this issue, although I’ve also not been using the app as much as I did before owing to it just not being very user friendly

Same but for a different location. I am none the wiser.

I’m still waiting for @metoffice.gov.uk to explain what the scales of these bars represent in their new app (it shouldn’t be this hard to understand!)

From Penzance to Thurso (and Marazion to Hoy)… it’s finished.

After 25 years, I’m delighted to report that the New Adlestrop Railway Atlas now covers the whole of England, Scotland and Wales in one big PDF. Every* passenger line and station.

Some students said "woo hoo!" in my lecture today when I mentioned today's sunshine, which goes to show just how bad the weather has been here lately

Interesting from a circulation perspective, because both 2020 and 1990 were strong +NAO coupled to/favoured by a strong stratospheric vortex. Not the case this time around.

Yes please. These icons were so much clearer.
