Many parts of France were on alert for severe storms three days. On the Sunday night (8 June) damaging winds gusting to over 110 km/h and large hailstones battered areas including the Val D’oise department near Paris and Dampierre-en-Burly.
At one point Météo-France put 32 departments in the country’s west and north on orange alert for 'violent' storms with heavy rain, hail, intense lightning activity and strong winds.
Tennis-ball sized hail was reported around the country (Photo credit: Corentin Léger).
It was reported that in the southern Paris suburb of Mormant a secondary school was closed after its roof was damaged by hail and the roof on another property collapsed.
A moderately active Spanish Plume situation evolved in the night of 8–9 June. Before midnight a cumulonimbus (Cb) cluster, a typical manifestation in the plume, started to grow over the Gironde estuary in south west France.
After midnight the cluster developed an extended anvil with cold-U signatures .
The night overpass of Suomi-NPP and its VIIRS imager coincided with the most active moment of the cluster. The high-resolution (375 m) image of IR12.0 (I5 band) indicates cloud-top temperature values as low as 190 K.
The IR12.0 image is overlaid with a semi-transparent Day-Night-Band (DNB) signal that shows the city lights of French towns surrounding the anvil as grey blobs, in particular Limoges on far right-hand side of the image.
Most interesting are the four brighter streaks over the anvil. They were caused by cloud illumination from intense lightning activity as the DNB sensor was rapidly scanning northwest to southeast.
