Weather events are highly variable and have to be split into two parts: area concerning the upper level front and the shallow moist area.

Upper Front

Parameter	Description
Precipitation	Moderate to heavy showery precipitation Quite often thunderstorms are observed.
Temperature	No signicant change
Wind (incl. gusts)	Around embedded Cb's strong gusts are possible.
Other relevant information	The upper front at the transition between high and low cloud part Hail and thunderstorms possible during whole year Risk of moderate to severe icing and turbulence

Shallow moist area, included surface front

Parameter	Description
Precipitation	Slight to moderate rain or drizzle
Temperature	Falls after the passage of the surface front
Wind (incl. gusts)	Veering of the wind at the front passage
Other relevant information	Precipitation in area of shallow moist zone behind upper front Risk of moderate icing With superimposed PVA-max showers and thunderstorms are possible. With showers moderate to severe icing and turbulence
