Model profiles show noticeably steep mid-level lapse rates, a fairly moist boundary layer + marginal deep-layer shear. Hail could become an issue in some stronger cores, while strong wind gusts also appear likely given well-mixed sub-cloud layers as shown in some high-res model output. #weather

The automated "SPC-style" rawinsonde.com outlook places a large part of NW Germany and the eastern Benelux countries under a "SLGT" risk today. There's some notable instability (MLCAPE 1500-2000 J/kg) underneath slowly strengthening W'ly winds (though shear remains marginal at first). #weather

Meanwhile, the focus of convective activity should shift into northwestern parts of central Europe on Friday, where a few strong to severe storms seem possible given a seasonally unstable air mass and marginally supportive deep-layer shear. #weather

Strong thunderstorms have been affecting parts of W and SE Europe "around the heat dome" over the past 48 hours. Some of these storms produced large hail and intense rainfall. #weather

Oxford, the longest running continuous weather station in UK history, with temperature observations stretching back to 1815, has preliminarily broken its maximum temperature record for May yesterday by OVER 3ºC with a temperature of 33.7ºC. Unprecedented in its 211-year history.

Mind boggling and on par with what we saw during the extreme heat in the western US in March in terms of anomalies.

It has been quiet on the convective front thus far thanks to the large-scale subsidence underneath the "Heat Dome". However, there is potential for a few strong, pulse-type thunderstorms today across the S UK in particular in an unstable air mass despite little upper-level support. #weather

Exceptional temperatures require exceptional atmospheric circulation. The intensity of the 500-hPa ridge ("heat dome") driving the present heatwave in western Europe is distinctly outside the monthly climatology for May.

34-35C likely as a max in the UK today, pulverising the old monthly temperature records from 1944 and 1922. SW France could see 37-38C locally several days in a row! We are experiencing an unprecedented May heatwave / heat dome. #weather

The Western European #heatwave is exceptional for May, but #climatechange has made it, in some places, more than five times more likely. csi.climatecentral.org

Let's suppose that in the current UK hot spell, Tuesday (26 May) is the hottest day. If it hits 34c, it would be the earliest to this value by a week-and-a-half vs. recorded history. If it makes 35c, it would be reaching this figure a MONTH earlier than we've ever experienced it.

Atmospheric swirl. Trapped air, forced to sink, within extremely strong anticyclones => potential record-breaking #heat in parts of the UK and France. #HeatDome #Weather #Heatwave www.ready.noaa.gov/HYSPLIT.php

The upcoming early-season heat will mainly affect (south)western Europe given the location and shape of the intense upper-level ridge. The EFI for 2m temperatures from Days 2-6 is at the top end of the scale, with significant (>1) SOT values as well. A remarkable signal #weather

Major pattern shift ahead across W and central Europe after a prolonged cool and unsettled spell. Upper geopotential heights are likely to reach record levels early next week. #weather

Texas Monthly writer Aaron Parsley deservedly won a Pulitzer Prize last week for his work describing the horror his family experienced in the July 4th TX flash floods. His words should stir a recommitment to improving flash flood and other wx warnings - and their communication. tinyurl.com/mu6bhvmj

High fire danger today across some parts of west-central Europe where gusty easterly winds overlap with very low RH (15-30%) and dry antecedent conditions. The high risk will translate east during the weekend. #weather (source: windy.com)

🌡️ Europe is the fastest‑warming continent, warming at more than 2× the global average. Changing weather patterns, reduced air pollution, declining snow cover & proximity to the rapidly warming Arctic all play a role. ⬇️

15 years ago today. The peak of one of the deadliest and most destructive tornado outbreaks in history.

Huge Pacific Heatwave - larger than North America - with record heat spanning 6,000 miles across, peaking in the East Pacific. The highest anomalies are near the Galápagos Islands, a clear sign a mighty El Niño is beginning. 1/

☀️ Image of the Week: How Sunny Was Europe in 2025? Much of the continent saw more sunshine than usual last year, while parts of south-western Europe came in below average. In the UK, 2025 was the sunniest year on record. Find out more at our website 👇 bit.ly/4cFZTUJ Data from @cm-saf.eumetsat.int

Happy #EarthDay! Meteorologists have the pleasure of looking back at our planet via NOAA GOES satellites as part of our everyday job. Never gets old. See for yourself: weather.gov/satellite. Also, visit noaa.gov/earthday for science stories, videos, and citizen science opportunities. #EarthDayNOAA

Weather satellites were able to see the Artemis II launch and re-entry. Space is cool, satellites are cool. It's all cool!!!

Our W/ctrl European convective season is slowly getting underway again. Some thunderstorms are possible later today across the Benelux and surrounding areas in a marginally unstable air mass ahead of the frontal passage/cool change. #weather

The Canary Islands enveloped in dust as waves and vortices swirl off of them. A fascinating, complex view.

Winter hasn't finished yet! There's fresh snow across the nearby Eifel and Ardennes hills this morning as a cold and unstable NW flow has arrived across W and central Europe. 12cm currently at Mont-Rigi in the High Fens, Belgium. #weather

The word “unprecedented” gets thrown around a lot these days to describe the ongoing heatwave across the Western U.S., and let’s be honest — it’s absolutely justified. Perhaps the most impressive multi-day event since the 2021 PNW heat dome.

In Phoenix, Arizona, temperatures could reach an unbelievable 107°F (+42°C) on Friday. If that verifies, it would break the record for the earliest occurrence of 107°F since records began in 1895, pulverising the previous record by a whopping 44 days. This is totally bonkers.

The seasonal anomalousness, as well sheer spatial extent, of upcoming record-shattering Western U.S. heatwave is genuinely startling. This will be associated with, by far, the strongest ridge ever observed during (at least) any Nov-Mar month. #CAwx #AZwx #NMwx #NVwx #UTwx #COwx

Grazalema, Spain, received over 2,000 mm (78 inches) of rain in just the last 20 days. Over a year’s worth of rain — and it’s only early February. This is hydrologically absurd.

New all-time minimum sea level in the Baltic Sea! The Föglö tide gauge measured just -71.6 cm below the mean level which is the lowest value ever recorded there. Records have been kept over 100 years, since 1924 (!). The sea level is still decreasing. (1/3)

Massive smoke plumes from a large bushfire near Gellibrand, Victoria, yesterday which prompted emergency warnings in the area. The fire even produced a towering pyrocumulus and pileus cloud as the hot updraft pushed through stable layers in the mid-levels. #fireweather #stormhour

A spell of extreme heat and fire danger is on the cards across SE Australia. We’ve been through 48C heat in the W Pilbara on 5 January, wasn’t fun 😅 Sth I noticed here: the visibility of information on natural hazards on many platforms, whether it’s cyclones, floods or fires. #weatherawareness

Landed in London. There was a CRAZY aurora outside on the flight over, I've never seen anything like it! Absolutely surreal...

As the climate data for 2025 continues to be released, it's time to update various data visualisations. First - the global climate stripes for 1850-2025. A third darkest red stripe is added. The last 11 years have been the warmest 11 years on record. A sequence that is unlikely to be broken soon.

Is damaging hail getting worse? An ESSL-led study published in Nature Geoscience finds that very large hail is modelled to occur most frequently in South America, the United States, and South Africa, but Europe shows the strongest increase in very large hail frequency. doi.org/10.1038/s415...
