Satellite pictures showed a vortex arrangement consisting of three cloud masses and two arching bands of cumulonimbus clouds, all of which were producing cirrus outflow.
In addition, the low resolution of the satellite imagery allows minor events, which do not make an impression on the satellite picture, to pass unnoticed.
Because of this temperature difference, warmth and moisture are transported upward, condensing into vertically oriented clouds (see satellite picture) which produce snow showers.
