Today the @metoffice.gov.uk issued its forecast for 2056, featuring the possibility of temperatures reaching 45°C in the UK. By chance, member #24 of today's 12Z GEFS ensemble is predicting 45°C in almost exactly the same location on 13th July 2026 – 30 years too early? @aidanmcgivern.bsky.social
Here's a look at numerous individual weather stations across a swathe of England + Wales, comparing the maximum temperature recorded during June 2026 with the whole of summer 1976 – in some cases temperatures were over 4°C hotter in the recent heatwave 🌡️ bsky.app/profile/meto...
The exceptional June 2026 #heatwave: - 130 wx stations (13 with data spanning ≥100 years) set new June TMax records - 124 (10 spanning ≥100 years) set new June TMin records - 26 set all-time TMax records, largely focussed in coastal counties - 65 sites set all-time TMin records
Near-stationary supercell thunderstorm over Swanton NE on Friday evening 🌩️
Thunderstorms in eastern Kansas on Sunday night were prolific lightning producers 🌩️
Once again, same process at play allowing observation stations situated on hills, above the temperature inversion, to record some impressively high minimum temperatures – including Pennerley (Shropshire) at 357m and Emley Moor (West Yorkshire) at 267m bsky.app/profile/meto...
Kenley was an ideal candidate to break the May daily minimum temperature record due to its elevation – at 170 m it sits above the temperature inversion, whilst many of its neighbouring sites below the inversion recorded lower temperatures overnight bsky.app/profile/meto...
Another pulse of unusually cold air for the time of year spreading south across the UK yesterday into today 🥶 00Z radiosonde ascent at Lerwick measured a 1000-850 hPa thickness of 128.6 dam (❌), sitting in the bottom 2% of the 31-day centred record. Already 6 air frosts at Kinbrace — May avg 4.6

Dyce (Aberdeen) has now recorded no sunshine for the past 14 days – its longest spell on record (since 1957) ☁️ The daily frequency (persistence) of SE'ly weather types in the objective Lamb Weather Types dataset (since 1871) was the joint 2nd highest on record for the month of January...
Merry Christmas all, on the highest pressure over the UK on Christmas Day since 1991 📈 The Scottish mountains have been poking above the subsidence inversion, where Cairngorm recorded a dewpoint of -41°C yesterday afternoon, with a corresponding relative humidity of 2%! 🏔️
In the HadUKP series for the "NW England and north Wales" region, Saturday 20th September 2025 was the 7th wettest day in the whole dataset back to 1931. For a two-day event, Friday 19th/Saturday 20th falls to 12th place, but is the wettest two-day period since Christmas Day/Boxing Day 2015.
Across a swathe of Wales and N'ern England, Sat 20th Sept was the wettest climatological day (09Z - 09Z) since at least New Year's Eve 2024. Loftus (N Yorks) recorded its wettest day, for any month, since Aug 2002; Trawsgoed (Ceredigion) wettest day since Oct 2018. Data @roostweather.bsky.social
Very energetic thunderstorms in eastern Scotland this afternoon, producing hail ≥3 cm in diameter and torrential rain — some unofficial gauges recorded as much as 50 mm in 15-25 minutes. The temperature at Aboyne fell by 11°C over a 24 minute period ⛈️
Storm #Floris, an exceptional summer storm 🌀 Provisionally: - Strongest August gust on record in Scotland - Equal strongest August gust on record in Northern Ireland - Lowest August mean sea level pressure in NW Scotland and Orkney since 1992 - Central pressure ⬇️ 28 hPa in 24 hours
Decent noctilucent cloud display from Devon (50.7°N) late Sunday evening ✨
An hour earlier, the same supercell thunderstorm moved through Gruver TX, with the tornado sirens blaring across town as Emergency Alerts ring on our mobile phones
Lightning over Spearman TX on Friday evening, shortly after a tornadic supercell thunderstorm moved through town
Genuinely lost count how many tornadoes were produced by this supercell thunderstorm that trundled ESE'wards from near Dora NM to Lubbock TX on Thursday afternoon/evening 🌪️
March 2025 was noteworthy for abundant sunshine and lack of rain — provisionally, it was the sunniest March on record in England, sunnier than July or August last year or the year before! ☀️ Wales (provisionally) had its driest March since 1944 & lowest number of March rain days (1 mm) since 1929. 🏜️
Despite the pesky cloud at times, a decent nibble and cheeky sunspot visible from Devon during this morning's Partial Solar #Eclipse 🌞🌚
An incredible satellite sequence from GOES-East over the US Plains on Friday evening. Severe thunderstorms erupting along the cold front, intense winds (60-80 mph) to its rear suspending vast quantities of dust (area covered is larger than the UK), and a significant number of wildfires (black spots)
Recent anticyclonic conditions has allowed many parts of England and Wales their sunniest start to March on record. Wattisham has already received ~50% of its monthly average sunshine in just 6 days. In stark contrast, Tiree has recorded its dullest start to March on record (data back to 1931).
105mm of rain fell at Nant Yr Ysfa (Rhondda Cynon Taf), 103mm at White Barrow (Devon), 06Z Sunday to 06Z Monday. Met Office warnings mentioned 80-100mm exposed hills in S. Wales, and 70-100mm Dartmoor. Accum rates similar to Storm Bert, but Bert lasted ~43 hours. Map: @roostweather.bsky.social
A few unofficial snow depth reports submitted to the WeatherQuest snow depth tool (weatherquest.co.uk/snowdepth/map) suggest as much as 38-40 cm across the north Pennines
Some places experienced freezing rain on Sunday — especially Wales and the Midlands, as confirmed by these BBC Weather Watchers photos. The deepest official snow depth reported was 24 cm at Copley (Co Durham) at 9am on Monday morning — but parts of the northern Pennines likely saw more than this.
