già nella ultima decade di aprile 2012 ...

Storm Forecast
Valid: Sat 21 Apr 2012 06:00 h UTC to Sun 22 Apr 2012 06:00 h UTC
A large low pressure area covers europe from ireland to ukraine
northern italy to central scandinavia
The low pressure centers are found over the western north sea 
and western ukraine
A cool unstable airmass with steep lapse rates and slight 
to moderate CAPE covers almost the entire area
Almost everywhere the small hail chances will be enhanced 
due to a low freezing level and not too low LCL
The eastern half of the area sees warm air advection 
into belarus and a weak 
trough coming in from romania
Flow and shear are weak there
Near an old front over poland some 15 m/s deep layer shear 
can enhance storm dynamics and larger hail chances
More dynamics and vertical wind shear are encountered 
over northern turkey and over central france through germany 
where a second cold upper airmass enters with linear forcing 
by a marked PV maximum
