Focusing on the development of the baroclinic boundary from 06.00 to 18.00 UTC on 14 June, we see a general northward movement in TFP in Fig. H30. Over Finland the boundary moves slightly to the west. The TFP reaches eastern Finland by 18.00 UTC. The CF part moves very fast northeastward. The temperature advection (H31) shows the same characteristics as TFP. There is northward movement of the WA maximum over Poland - White Russia at 06.00 UTC to the Baltic States at 18.00 UTC. At the same time the WA maximum is intensifying. Looking at the 500 hPa height contours (H32), there is an eastward shift and intensification of the upper level trough over the Balkan peninsula and even the formation of an Upper Level Low. The continuous broad upper level flow from the south to Finland stays strong and even strengthens over the Ukraine. Tying these NWP observations to the 18 UTC satellite image we have a verification for the predicted development. The northward movement of the baroclinic boundary can also be seen in the cloudiness ahead and within the TFP areas over the Baltic Sea, the Baltic States and Southern Finland (H33). The cloudiness appearing within the warm sector in western Russia indicates unstable developments.
