The images show the path of frontal parameters like TFP (left image) and WA (right image) during the next 12 hours from 06.00 UTC to 18.00 UTC. There is a fast eastward propagation of the TFP across Ireland to England; in the same time interval the warm sector becomes more and more narrow and a spiral structure develops north of Ireland. The WA maximum related to the Warm Front moves in accordance to the TFP and reaches the North Sea and west Europe at 18.00 UTC.
