"....N-France, the Low Countries and NW Germany...
A broad, but still not well defined, developing upper-level trough will cross the area of interest .... Cool mid-levels should enhance the lape rates and an area of 200-400 J/kg instability should develop... That much instability, combined with low LCLs and weak background shear will pose a funnel / short tornado / waterspout threat in the highlighted areas.... Indications are, that temperatures in the 700hPa level will drop 5-8°C in some locations ( compared to yesterday ), which should confine the region of an instability maximum to the lower levels ( also supportive for possible cold-air funnels )."
