True Colour RGB - 25 May, 10 UTC - MTG satellite imagery shows mostly cloud-free conditions across large parts of western, central and southern Europe. The widespread absence of cloud cover is consistent with stable anticyclonic conditions and subsidence, which suppress cloud development and favour strong heating of the land surface. Such a synoptic pattern contributed to the development of a heatwave across much of Europe, causing exceptionally hot days and nights, with the UK breaking its highest May temperature record. The MTG True Colour RGB combines red, green, and blue visible channels to create realistic colours as perceived by the human eye, with a spatial resolution of 1 km.

FCI 10 min IR Sandwich - 20 May 2026, 15 UTC - On the border between Finland and Russia, a cold front initiates convection in a warm and moist airmass. This convective multicell system, in particular, was quite long-lived, with first signs of active convection at 10 UTC and some areas with lightning prevailing until nighttime. The Sandwich product is very good at distinguishing deep convection during the day and it shows the cloud top features well, for example, an overshooting top in the middle in orange. The more the colour leans red, the colder the cloud top.

High Rate SEVIRI WV6.2 μm and Blended SEVIRI/LEO MW Precipitation and Morphologic Information – 11 May 2026, 18:30 UTC – Over central Europe, a broad precipitation area associated with a cold front can be seen, with locally enhanced precipitation embedded within the frontal cloud band. In the High Rate SEVIRI WV6.2 μm image, which focuses on the water vapour absorption band, an area of high humidity can be seen in gray to white tones. The highest precipitation amounts are visible in shades of blue in the Blended SEVIRI/LEO MW Precipitation and Morphologic Information product, with the scale ranging from light yellow to dark blue and showing precipitation intensity in mm/h. The product uses geostationary (GEO) IR images “calibrated” by precipitation measurements from MW images on Low Earth Orbit (LEO) satellites, making it useful for estimating rainfall rates at high temporal frequency.

Himawari Severe Storms RGB – 6 May 2026, 05:40 UTC – Tropical Storm 05W (FIVE) is located around 700 km south‑southeast of Guam and is currently moving west‑southwestward under the steering influence of a subtropical ridge to the northeast. In the Severe Storms RGB, deep convection appears in yellow to red colors with small ice crystals present at the cloud top level. The strongest convective activity is displaced to the western side of the circulation, where the strongest wind shear is also present.

The low‑level circulation is mostly exposed, with limited deep convection over the center. This asymmetric structure reflects ongoing wind shear and the intrusion of drier air, which are currently inhibiting further organization. The Severe Storms RGB is a useful tool for assessing convective severity and its development.

The EUMeTrain Consortium is meeting in Helsinki at FMI from 28-30 April to discuss about the past & future training materials, courses and other project activites related to satellite meteorology!

EUMeTrain EUMeTrain Weather Briefing - April 2026

GeoColour RGB and LI Accumulated Flash Area – 19 April 2026, 16:30 UTC – A severe storm is pictured over northern Italy in the GeoColour RGB product and in its composite with the LI Level 2 Accumulated Flash Area (AFA) visualisation product. In EUMETView, AFA shows the 5-minute flash count within the accumulated flash area by combining 10 half-minute AFA products. In the GeoColour RGB, an overshooting top of the cumulonimbus cloud can be seen overlapping with the area of the highest flash count, which indicates the position of the most intense lightning activity and the storm’s most active convective core.
