Hallo,
Estofax verwacht vanavond erg zwaar weer met mogelijk "supercells", ten ZO ( zie plaatje )
Luxemburg valt nog onder zone 2 !
DISCUSSION
...Northeastern France into northern Switzerland and southwestern Germany...
A level 2 has been issued, meaning a threat of widespread severe weather, and the possibility of isolated extreme weather. As a shortwave through moves through the area it will cause widespread convection.
The strong midlevel winds, described above, would generate 15-20 m/s deep-layer shear (0-6 km), while SREH will surge to values over
100 m2/s2 over a large area, possibly >250 m2/s2 over a smaller area. These numbers are equal or better than we have seen yesterday, which proved to be sufficient for supercells. More supercells, with a capability of producing isolated large or perhaps extremely large hail and severe gusts will be likely today. There is an increased threat of tornadoes, because the low-level (0-1 km) shear reaches over 10 m/s, in combination with LCLs not too high, between 1000-1500 m.
As convection is expected to coagulate into a rapidly moving MCS (squall line with bow echoes) towards or during the evening, the threat of especially widespread severe gusts will increase.
