A long extended Cold Front lies from Germany to Switzerland. It is characterised by unstable stratification up to 800 hPa and an expected displacement to the east of about 3 degrees within 12 hours. Ahead of the Cold Front a large unstable area can be observed with Showalter index below 3, even below 0 in part. A pronounced low is situated over the Norwegian Sea. 1000 hPa height contours show a pronounced trough with axis oriented southeast northwest, from Croatia to Denmark. 500 hPa height contours show a trough axis over France. TFP, TA and thickness indicate a typical frontal situation. The maximum of TFP is located above Switzerland, followed by a thickness trough immediately behind. The frontal cloud band lies within CA whereas the convective system in the east is under the influence of WA. The jet axis runs along the rear edge of the Cold Front cloud band. A pronounced jet streak can be seen over Denmark. In the eastern part of Austria the Showalter index is below 0. The prefrontal unstable Showalter values increase within the frontal cloud band. A narrow line of convection can already be seen.
