12 Oct 2025 12 UTC Temp Anomalies A lovely sunny afternoon across the Highlands, with temps +4°C above the LTA for 12 UTC. Cold in contrast across centrals parts of England with anomalies of -5°C in the low cloud & fog. #ukweather

12 Oct 2025 09 UTC Analysis I had to go quite away E to find a front to draw on this mornings chart. Colder air with sub-zero dewpoints moving S down across Scandinavia. #ukweather

1-11 Oct 2025 Mean Temp Anomalies The rather warm start to Oct continues across NE Scotland, close to average further S. I've not heard a single mention of this from the BBC or UKMO. #ukweather

10 Oct 2025 08 UTC A lovely satellite image if you like orographic low cloud, unfortunately we are under it at the moment. The rolls of cloud are so dense, it also makes them very dark and threatening. #ukweather

9 Oct 2025 09 UTC Analysis Another day, and another cold front. #ukweather

9-22 Oct 2025 12 UTC ECMWF All good things must come to an end. So much for it lasting well beyond T+240, as some were suggesting it might. #ukweather

8 Aug 2025 08 UTC Temperatures A mild morning across the whole of the UK & Ireland, but mildest ahead of the cold front across SE England. #ukweather

3 Oct 2025 15 UTC Analysis Humberto tracking N'NE west of Hebrides. #ukweather #Humberto @metoffice.gov.uk

3 Oct 2025 15 UTC Max Hourly Gusts Still gusting 85 mph at Capel Curig. Gusts to 98 on Cairngorm at 16 UTC, 102 on the Cairnwell at 15 UTC, the Needles not far behind! #ukweather #Humberto

Sep 2025 Weather Summary Regionally, N Scotland gets a 1-1-2 for driest, warmest & sunniest anomalies once again. #ukweather @metoffice.gov.uk

Storm Amy should have been named Storm Humberto! The rules laid out explicitly on the UKMO Storm Centre website clearly state that the name of the storm WOULD NOT CHANGE. #ukweather #Humberto #amy @metoffice.gov.uk

26 Jun-25 Sep 2025 UK & Ireland Daily Composite Temperatures Undoubtedly, the coldest week of the last 3 months, ushers in an early Autumn. #ukweather

20 Sep 2025 12 UTC 24 hr Temp Differences As much as 10°C colder across North Yorkshire at 12 UTC than it was at the same time yesterday. #ukweather #cold

20 Sep 2025 09 UTC Analysis A fascinating chart this morning. How the Met Office can call the cold front across Scotland an occlusion when it's dropped dewpoints by more than 5°C beats me! #ukweather

1-19 Sep 2025 Total Precipitation POA 1⃣The chart on the left is the percentage of the LTA for the first 19 days of Sep. 2⃣The chart on the right is the guaranteed MINIMUM percentage for the whole month. #ukweather

25-28 Sep 2025 ECMWF Latest forecast suggest what's likely to be ex-Hurricane Gabrielle will track eastward towards the SW approaches later next week, bringing plenty more rain with it. #ukweather #Gabrielle

19 Sep 2025 12 UTC Temps Quite a N-S contrast in temperatures across the UK this lunchtime, from 14°C in Fair Isle, to 25°C in London to 29°C in Paris. #ukweather

The wettest Septembers in the UK since 1910 www.weatherdiary.uk/2025/09/15/t... #ukweather

14 Sep 2025 12 UTC Analysis The warm air is very reluctant to move into the SW. Improved the plotting again. I already hate Windows 11 with a vengeance. #ukweather

14 Sep 2025 12 UTC The UKV has the low much further east than other models. But will it be storm Amy? Difficult to say at this range. #ukweather #stormAmy

9 Sep 2025 Min Temp [18-06] A cold night for Aug in the E, with a slight frost in the Highlands, milder further W. None of the chilly & cool euphemisms here, not with anomalies as low as -9°C. #ukweather

7 Jun-6 Sep 2025 National Daily Temps & Anomalies 1️⃣These two charts are a great example of why I like to use anomalies as much as I do - anomalies don't hide things. 2️⃣Very few colder than average days in the UK at all this summer, let alone a cold spell. #ukweather

7 Sep 2025 06 UTC Temp anomalies A very mild start to the day, particularly in the W, with anomalies +6°C or higher than the LTA in many places. #ukweather

Summer 2025 in the UK may well have had the highest mean temp, but as far as the summer index [SI] was concerned, it was only 8th highest. Summer 1976 in the UK had a perfect SI of 48, in effect 1976 can only be equalled, never bettered. #ukweather #summer

4 Sep 2025 00-12 UTC Rainfall accumulations Estimates from weather radar Todays small thundery low never managed to get a proper circulation going, but it's put down a good deal of rainfall as it tracked NE. #ukweather

Aug 2025 ERA5 Global 2M Temp Anomalies August 2025 was the third warmest since 1940, but is significantly down on last years record by over 0.2°C. #ukweather #globalwarming

1976 is still the warmest (and sunniest) summer on record in the UK since 1884 despite what the Met Office say. #ukweather

25 Aug-1 Sep 2025 Max Temp Anomalies The summer just hasn't realised that it's come to an end across the NE. #ukweather

1-30 Aug 2025 Mean Max & Min Temp anomalies August was a bit of an unusual month, warm by day, but not so much by night, apart from Eire. #ukweather #climate

Total Precipitation 🟩1-30 August 🟩25-30 August Much, and in some places nearly all, of this months rainfall has fallen in the last 5 days. Despite the cyclonic nature of the weather, the dry spell continues over many parts. #ukweather

290600-300600 UTC Ulrich has deepened explosively from 1003 to 975 hPa in the 24 hrs till 06 UTC this morning. It's a good job it's doing it at 12 west and not 5. #ukweather

30 Aug 2025 12 UTC T+84 Autumn come early? One last storm of the season? You can bet that's what the theme of the day will be for this weekend's weather. Gerben? What happened to Geoff, Gerald or George? #ukweather

24-27 Aug 2025 ECMWF 250 hPa winds How's Erin going to interact with the 175 mph WNW jet in the Atlantic next week? Just who is in control, Erin or the jet? Today's 10 day trend from the Met Office will be very interesting. #ukweather #Erin

1 Jun-17 Aug 2025 Mean Temperature Summer 2025 could well be on track to being the warmest on record. I make the UK mean anomaly +1.9°C just ahead of the +1.8°C of 2018. It all depends on just how the last days of August pan out. #ukweather

17 Aug 2025 0600-1100 UTC The low SC sheet has edged into eastern England on the NE'ly breeze this morning. As the sun climbs higher, you can also make out the smoke streaming up across the SW from wildfires in the SE'ly flow from Iberia. #ukweather #wildfires #haar

23-28 Aug 2025 ECMWF The forecast for ex hurricane Erin is firming up on a hit on Scotland, after a short pirouette to the NW. #ukweather #Erin

14 Aug 2025 0900-1245 UTC It took just an hour for this CB and thunderstorm to explode into life across the Grampians this lunchtime. Quite amazing. I wonder if there's a time lapse? #ukweather #thunderstorm

1-13 Aug 2025 Mean Max Temp Anomalies A warm first half of August, particularly in the east. #ukweather

13 Aug 2025 Consecutive heatwave days Yesterday's cloud but the kibosh on the heatwave in the south. #ukweather #heatwave

13 Aug 2025 12 UTC Temp anomalies Heatwave conditions have moved northward into N England and Scotland today, with anomalies as high as +12°C above the LTA. Cooler across the S & SW. #ukweather #heatwave

1 Mar- 12 Aug 2025 Precipitation POA The dry spell continues. The hyetograph for Yeovilton shows just how dry it’s been in Dorset since the start of spring. #ukweather #drought

13 Aug 2025 11 UTC 24 hr temp differences As much as 10°C colder than yesterday across the S & SW of England . Much warmer over central northern England. Another 25°C max in Strathpeffer. #ukweather #heatwave

12 Aug 2025 12 UTC Temp anomalies The glorious 12th, with heatwave conditions continuing across large parts of France & Spain, maybe extended a bit further E than yesterday. #heatwave #ukweather
