This case has an appearance very close to the classical description.
The Warm Front cloud band can be observed on the Atlantic (east of approximately 25W) extending to Scotland and Northern Ireland. Several features mentioned above can be observed:
Also the relation of the cloud band and the key parameters is very close to the ideal case (see Key parameters).

This case shows some deviations from the ideal cases.
The cloud band of the Warm Front can be located in the IR and WV images from the south-eastern part of Sweden across the Baltic Sea and the Baltic countries to the Ukraine. In the IR image it consists of several high, i.e. cold, cloud areas and cloud lines superimposed on dark grey, i.e. warmer, cloud tops. In the WV image a broad white band in the area of the Warm Front indicates high water vapour content which is bounded by dark stripes on the northern as well as the southern edges. The northern stripe represents the dry air on the cyclonic side of the jet. The dark grey area extending from the Benelux countries across Germany and Denmark to Poland is an area of Fog and Stratus cloudiness.
