Incredibly close to the UK October MSLP record with 948.1 hPa at Stornoway at 22Z Saturday, but just slightly north of the centre of #Boelo. It's likely a lower MSLP value would have been recorded had there been an observation station farther south on Harris. bsky.app/profile/danh...

As Storm #Boelo tracks across/close to N/NW Scotland on Saturday night, its central pressure is likely to be 946-949 hPa. The current UK October low MSLP record is 947.9 hPa (Storm Amy 2025). There's a chance we could beat this... just one week after near-record high MSLP! bsky.app/profile/danh...

A busy day for our teams @metoffice.gov.uk with Storm #Austen expected to bring impacts to SW England and W/SW Wales early Friday, and then Storm #Boelo across more northern parts of the UK over the weekend... 🌀 www.youtube.com/watch?v=-xwV...

We have seen reports of wind damage in Frinton-on-Sea, Essex that appears to have occurred around 11:45 BST today with reported structural damage to roofs and trees. Please do get in touch if you have any further reports, either below this post or through the form on our website.

1040.4 hPa at Tulloch Bridge on Saturday morning makes this the strongest high pressure over the UK in October since 2018 — and in Scotland since 2016. Several sites with ~30 years data have set new October MSLP records in S'ern Scotland, N'ern England & Northern Ireland. @alexdeakin.bsky.social

Analysed as 931 hPa on 12Z ASXX, with a fall in central pressure of 49 hPa in 24 hours, this exceptionally deep low near Iceland more than satisfies explosive cyclogenesis 🌀 Potentially a record deep low for October in Iceland with 935 hPa observed on land... 📉 bsky.app/profile/meto...

It was an exceptionally warm night across the UK for late September, with some stations recording 22°C during the early hours. The temperature has been rising all through the night at Edinburgh, for example. Red box highlights just how much last night stands out from individual site records.

The Partial Solar Eclipse of 12th August 2026 over east Devon – maximum obscuration around 94% ☀️🌗🌍

Experimenting with ways to convey extremeness of a month/season as a combination of temperature, rainfall and sunshine. Eventually settled on these "Climate Segments", which really highlight how exceptional July 2026 was in England/Wales. More details in the Deep Dive: youtube.com/watch?v=m-om...

On this day 5 years ago, thunderstorms caused significant flooding in parts of East Anglia, London and SE England. Brettenham (Suffolk) received ~180 mm of rain in less than 2 hours – one of the most intense short-duration rain events recorded in the UK. www.youtube.com/watch?v=PNP0...

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 🌩️

New paper looking at very large hail (up to 5 cm in diameter) in E'ern Scotland in Aug 2025. A cell merger event, coupled with complex topography, may have been partly responsible for the enhanced hail size in an otherwise weak wind shear environment. rmets.onlinelibrary.wiley.com/doi/10.1002/...

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

The Easter weekend is looking very unsettled, especially towards the northwest with a series of low pressure systems set to push through 🌧️ Find out more in our latest Deep Dive with Alex Burkill 👇

Wondering where the sunshine has gone? Spare a thought for northeast Scotland; Aberdeen Dyce hasn't recorded any sunshine since 21 January! This is provisionally the longest sunless period here since records began in 1957 ☁️

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...

Information is from Stephen Burt: Reading has seen 24 consecutive days of rainfall, the longest unbroken spell of consecutive rainfall days at Reading since daily rainfall records began in 1908, beating the 23 days set in December 1934 and in January 1970. It has been very wet.

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%! 🏔️

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

06Z surface analysis from @metoffice.gov.uk showing Storm Floris at 983 hPa just west of Scotland. The frontal analysis follows the Shapiro-Keyser cyclone model, with a frontal fracture (cold front detached from the warm front). S-K cyclones are typically among the most intense & rare in summer.

A beaut of an MCV (Mesoscale Convective Vortex) - h/t @danholley.bsky.social

Decent noctilucent cloud display from Devon (50.7°N) late Sunday evening ✨

Popped in to the @metoffice.gov.uk Deep Dive studio yesterday to chat about supercell thunderstorms 🌩️ youtu.be/AR6Egr5UzOc

Lightning under moonlight, west of Channing TX on Saturday evening ⚡🌚

Incredible supercell structure near Amistad NM on Saturday evening 🌩️

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 🌞🌚

Guest appearance on this week’s @metoffice.bsky.social Deep Dive with @alexdeakin.bsky.social, discussing the recent dust storms, wildfires and tornadoes in the U.S. youtu.be/XwtSmKim23w?...

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

For those wondering about the Halloween 2021 mesolow, a paper authored by @danholley.bsky.social and many members of @torrouk.bsky.social can be found in Weather rmets.onlinelibrary.wiley.com/doi/epdf/10.... However, at present we don't yet know how tonight will evolve. All eyes on the south coast.

Tonight's development of a mesolow looks to take a broadly similar path to one seen on 31st October 2021 (h/t @danholley.bsky.social to the similarity on that one). The corridor of strong winds from these only tends to be ~20-30 km wide but does pack a punch, perhaps caused by a small stingjet.
