@mariusor measured temperatures. The anomalies are much higher, widespread -6 K.

Toxic #smoke plume of Canadian #wildfires spreads towards #NewYork. Extreme fine #dust concentrations of over 400 μg/m³ (PM2.5), however, we also reach in #Germany: when atmospheric inversion coincides with #fireworks and/or high #woodstove density. :(#Weather

First hot spell in parts of west-central Europe for this year. It will be the warmest day of the year so far, with highs of 30 °C in some areas. However, the air mass is relatively dry and the nights are still quite cool, so that the heat is not yet so stressful. #Weather #Temperatures #Heat #Forecast

The global mean temperature exceeds the threshold of +1.5 degrees for the first time during the boreal summer, favoured by the emerging El Nino. Previously, this was only the case during winter and spring. The 1.5 degree target is wobbling precariously.@CopernicusECMWF https://climate.copernicus.eu/tracking-breaches-150c-global-warming-threshold?utm_source=tw&utm_medium=socialmedia&utm_campaign=globalwarminglimit-june23#ClimateCrisis#Klimakrise

Ernüchternd, wie sich immer mehr Menschen mit ihrer anekdotischen Schein-Evidenz von "45 Grad anno dazumal" über Fakten hinwegsetzen. Lasst die Wissenschaftler ihren Job machen und schenkt ihnen etwas mehr Vertrauen!Zur schwülen Hitze und starker Wärmebelastung die Videobotschaft vom @DeutscherWetterdienst https://youtu.be/KWUW635VF_w#Hitze #Wetter#Unwetter#Klima

Dinner is served: the fresh #Sounding from Idar-Oberstein impressively shows the #thunderstorm potential in parts of #Germany (EML, robust CAPE, neat DLS). Further east, LLS and helicity should be added with deepening surface low.All conditions fulfilled for severe thunderstorms, including #Tornado potential.#Weather#WxMastodon#Storms

Building #Heat in parts of southwest/central #Europe and the western #Mediterranean late this week. The animations show the IFS forecast of temperature at the 850-hPa level and the probabilities for maximum temperatures above 35 °C. Accordingly, a larger area could be affected by extreme heat on Sunday and Monday. Locally, up to 40 °C could be possible. In the African Mediterranean rim it will be particularly hot with highs up to 45 °C.#Weather #Forecast

An unusual summer #storm threatens parts of west-central #Europe on Wednesday. The fast-moving secondary low could bring gale-force, possibly even hurricane-force winds in small areas. The satellite image simulated by IFS shows the storm as an impressive cloud whirl.Image: @kachelmannwetter #Weather#Forecast

There is something really serious going on in the #Weather models for Wednesday. A classic rapid cyclogenesis with massive dry intrusion. Very unfortunate timing especially for the North Sea neighbors #Netherlands, #Germany and #Denmark. In a narrow stretch on the southwest flank of the system, damaging wind gusts could occur due to a sting and/or cold jet. #Forecast #Storm #WxMastodon

#StormPoly in the making or: a bit of satellite meteorology. The upper trough (area of dry air: yellow/orange) is beginning to interact with the frontal zone. The leaf-shaped thickening in the cloud cover indicates that a disturbance (frontal wave) has already developed. #Weather #Satellite #Meteorology

#StormPoly in all its glory. What was once a frontal wave has developed into a full-blown storm cyclone. The strongest gusts (>120 kph) occur at the top of the so-called "cloud head" (currently Dutch coast). This area of strong winds will extend to NW-Germany. @kachelmannwetter https://kachelmannwetter.com/de/sat/dd938a6fdae4701aedd593b53273b857/satellit-hd-5min.html

#Storm #Poly has developed multiple rain bands. Unlike tropical cyclones, however, the strongest gusts tend to occur in the outer bands. The storm center now reaches East Frisia. #Radar#WxMastodon#Weather@RadarOmega

3 simultaneous #Heatdome|s over N-America, the tropical N-Atlantic, and the W-Mediterranean. Shown is the geopotential, which is (near) record high in all 3 areas. The strong upper anticyclones favor large-scale, strong subsidence and adiabatic heating.#Heat #Heatwave #Weather

The backward #Trajectories for #Sicily clearly show how the air is trapped in the broad circulation of the anticyclone, descending as if in a swirl and heating. #Heatwave #Heatdome

The heat is therefore "home-made" and not advective. This form of heat waves seems to have increased, due to persistent weather systems. They can be much more intense than the heat dominated by air mass advection. Those that can combine both processes are particularly dramatic.

600 km long #rollcloud (official cloud atlas name: #volutus) over the western Mediterranean. It is caused by a southwards moving pressure wave, which itself is formed by a shallow cold air outbreak, canalized and accelerated through the Rhone and Aude valleys (#Mistral/#Cers).#Weather #Satellite #Clouds

Potentially catastrophic #Flooding in #Greece due to "hybrid" precipitation event (synoptic-scale+convective). Over a large area widespread 150-300 mm in 48 h, in exposed mountainous areas and due to thundery intensifications locally even significantly higher totals above 500 mm. #Weather #Forecast
