Gotta love a cheeky squall line

The cold front is rolling through here now - nice tumble from 15.2C at 2119 BST to 13.5C at 2128 BST and still dropping!

Today marks one year since the memorable thunderstorm outbreak that affected parts of the UK and Ireland, but more notably areas of eastern England. Here are the best photos and videos I found from the event. 🧵

Sunshine and showers tomorrow although I believe AROME may be overdoing the extent of these showers but we shall see how it turns out properly. A small chance of any hail and thunder with these but feeling cool!

University of Reading HUXt model showing two CME arrivals in the next 3 days. Looks like the second one, from the M1.2 LDE today will pack a stronger punch. #aurora

The first snow of autumn on the Scottish mountains occurred yesterday, a definite show that cooler air has arrived

A few thoughts on winter An interesting combination of Solar Max, QBO W, and weak La Nina developing going into winter Some of the modelling is suggesting a more East based Nina, this is what cold fans need A EP based Nina favours a -NAO. So eyes on this MJO A good MJO wave

Herstmonceux's 850 hPa temperature at 00z [1.6C] is a record daily minimum for 11th September at the station since it began launching radiosondes in 2000. The previous record daily minimum of 3.6C was set in 2001 and tied in 2020. Data & graph is from Dan Harris

There are a lot of showers developing currently, risk of small hail and thunder in them.

Greetings tiny outflow shelf cloud that looked far more impressive when I left the house 😂 🤦

It’s definitely autumnal, nice cloud structures running down the Estuary
