This past week, Ukrainian drones struck and sank a Russian shadow fleet ship in the Mediterranean carrying liquefied natural gas from a sanctioned Arctic project. A European Space Agency researcher shows how a weather satellite captured the initial explosion.

Saharan dust persists over Central Europe, yet global solar radiation and PV output exceed yesterday’s levels! Webcam and ceilometer data suggest a slight reduced dust load, possibly due to dry deposition.

A massive cloud of Saharan dust is currently hanging over southwestern Europe, clearly visible this morning with characteristic rippled high clouds above the western Mediterranean. The dust cloud, now detected at an altitude of about 3–4 km by ceilometers and webcams in the Swiss Alps.

Climatological winter 2025/2026 was globally the 5th warmest. Across Europe it was split: too cold and too dry in the northeast, but too warm and too wet elsewhere. Big kudos to @climatologist49.bsky.social

A pronounced trough extending far south over Morocco is advecting warm air and Saharan dust—partly from Mali and Mauritania—northwards on southerly winds ahead of it. Clearly visible now over northern Spain. The dense dust cloud, at an altitude of ~3 km, will reach northern Switzerland tomorrow.

Latest MTG satellite imagery (Day Snow Fog RGB) shows fog over Lake Constance (with late-winter cold 4°C) and early pre-spring convection with cumulus over the Black Forest, Jura, and western Prealps (white dots). Alpine snow appears red...

Very sunny day in Switzerland - as seen by NOAA20: With often clear sky and highest temperatures of this (climatological) winter: 19° in Delémont/Jura. But not directly at Lake of Constance: with lasting fog and cool SST only 7°C Sahara dust of France, clearly visible then on Saturday...

Apart from fog in the northern and low stratus in the southern lowlands, the whole Alps are presenting today in bright sunshine and with clear skies —for the first time in two weeks. There is still plenty of snow (shown in blue): snow cover fraction is close to average for this time of year.

With northerly foehn over the Alps on the southern side of the Alps, temperatures are mild with 20 to 24°C—while with a southerly foehn in the Basque Country (northern Spain), they even reach up to 28°C! Meanwhile, record-breaking cold in Greenland 🥶

In polar areas, there is an annual decrease in mean sea level pressure. In the Dec-Feb period, lower air pressure has been prominent across mainland Alaska.

Northern and eastern Europe still covered with snow (white) sea-ice (blue), whereas western Europe is now snow-free. In Switzerland, overall snow cover is below average; however, certainstations in lower Valais—e.g. La Creusaz (1,710 m), west of Martigny—have recorded unprecedented snow depths!

For the first time since records began in 1950, France’s multi-week national MSLP has dropped below 1000 hPa. The persistence of this low-pressure pattern across western Europe in recent weeks has been nothing short of historic.

Under 6 months until Europe has a brilliant view of a Total Solar Eclipse. I'll see 90% Partial from Newcastle. While rest of UK can see over 90%. Totality visible from Greenland, Iceland, Portugal, Spain, Russia. 12 August 2026. 🔭 🧪 www.timeanddate.com/eclipse/sola...

Significant Saharan dust concentrations over western Africa and the adjacent Atlantic, also over the Bodélé Depression (Chad/Niger). The plume is projected to envelop the Canary Islands in coming days, potentially reaching western Europe by next weekend.

Today, the sea ice extent in the Baltic Sea reached 178,000 km², surpassing the winter 2018 maximum and marking the highest extent since 2012. en.ilmatieteenlaitos.fi/ice-conditions

Winter 25/26 was so far in Nepal super dry. With a weak upper-level trough (WD) today first pre-monsoon thunderstorms occured in central Nepal with locally up to 15 mm

First 10 days of last climatological winter month ... again too cold in northern/eastern Europe and too wet in southwestern Europe (by JMA).

Sunday morning in Nepal: fog in some valleys, thick stratus over Terai (adjacent to India). During the day, cumulus cloud form along the foothills of the snow-covered Himalaya (depicted in blue). These clouds are parameterised in the models as weak convective precipitation, though it remains dry.

Here are the same maps but the time series is for the polygon that generally represents the mountains.

In the GAR (greater Alpine Region) January 2026 was a bit colder than usual ... and partly very dry and partly very wet.

Russia’s full-scale invasion began 4 years ago. It began in winter, and so this winter is the 5th. And, for civilians, the worst. Russia launches missiles and drones at energy infrastructure to force Ukrainians to endure the freezing cold. Here's how you can help snyder.substack.com/p/the-long-u...

Winter 2025/2026 so far in Europe with +/- average temperatures. In northern and esp. central Europe too dry: record drought between eastern Switzerland and southern Poland. But already record wetness in western Mediterranean and southern UK.

January 2026 was colder than usual in Europe (referring to reference periode 1991-2020), but only in northern Scandinavia locally the coldest since 1940

Despite recent headlines about cold snaps: January 2026 was globally again too warm and ranked as the fifth warmest since 1940, continuing the trend of above-average temperatures (Thanks to @climatologist49.bsky.social)

Delighted to see this research in @rmets.org Weather!

A brief but intense Intense southerly foehn over the Alps: summit gusts ~120 km/h, typical foehn valleys locally >100 km/h and 15°C by Tuesday morning! Pressure gradient over Alps good proxy for y/n (~4 hPa) and strength. Foehn subsides today rapidly from west→east, but briefly returns late Thursday

A dry January 2026 in Switzerland: The majority of stations recorded precipitation levels between 40% to 80% of the long-term average. Total monthly amounts varied between 10 l/m² (northern Grisons) and 150 l/m² (upper Jura), with a maximum of 207 l/m² recorded at mount Säntis in eastern Switzerland

Despite some fields of cloud and widespread stratus over the lowlands: the Alps today -even under low atmospheric pressure (1005 hPa) - remain frequently sunny and snow-covered (with a bluish tint). The current extent (not height) of the snowpack—now at its seasonal maximum—is above normal.

How unusual is this upcoming cold outbreak in Florida? Per the latest forecast, the cold airmass aloft is within 1-2 degrees Celsius of the **year-round** cold record from 1950-2024:

Following the devastating winter storm last weekend, many people across the South were left without power, as can be seen in this nighttime visible imagery.

Sea Surface Temperature around Europe were record high again in 2025. No one can (falsely) blame El Niño for this.

Clear sky over the Alps, snow red colored. At Zurich Airport (LSZH), cold fog is dissipating, coinciding with the approach of a United States Air Force aircraft. Over Italy, dense high-altitude cloud cover, with the presence of Saharan dust exhibiting typical rippled cloud-tops.

Preliminary forecasts suggest that January is likely to be significantly colder than average across Northern and Eastern Europe. Initial projections for February 2026, compiled from 13 meteorological centres, indicate ↘️

Europe temperature categories for the full year (2025). Seems bad.

Low stratus blankets the northern Alps today, pushing into pre-Alpine valleys with a ceiling of ~800m (Rigi webcam); valley shape+exposure matter more than the fog’s height. Alpine valleys have foehn with up to 14°C, the southern Alps have thick cloud (but little rain), spilling over the main ridge

Over 50% of the Earth has experienced their warmest year since 2021!

Let's check in a see which year since 1940 was the warmest and which one was the coldest for all of the Earth. Red colors are closest to 2025, and blue colors are closest to 1940. I spot a slight difference.

The first half of the first month of the new year was also too cold across Europe (according to the JMA). The latest ECMWF weekly forecasts show the cold weather continuing over the coming week 4 and 5...

Partly persistent low, cold (Zurich area highs only 1°C) dense fog over Swiss plateau, as seen by NOAA21 at 12h03 UTC. Alpine foehn valleys on the other hand up to 15°C. Dense high/midlevel clouds from south, even with dust from Sahara and Sahel!

Storm Goretii (Elli) brought significant snowfall to central Europe, covering now 99% of Germany—except the Rhine valley. Climatological maximum is typically 40–45% snow cover end of January. However, this snow is forecast to melt within the week...

First 10 days of the new year were too cold all over Europe (JMA). But next two weeks milder weather will prevail (by ECMWF)

Baroclinic zone—juxtaposing subtropical air (SW) and Arctic air (NW)—will spawn a cyclogenesis SW of Ireland Thursday morning. Rapid deepening (bombogenesis) will reduce MSLP to ~970 hPa by 00 UTC Friday (cyclone ‘Goretti’ by Météo-France). With strong westerly winds temporary thaw in western Europe

The calendar year 2025 was the third warmest globally and in Europe since 1940, according to ERA5 data. Thx to @climatologist49.bsky.social

Antarctica had its warmest year on record. That seems fucking bad. 🔥🔥🔥
