At 12.00 UTC the PVA maximum in the investigated area has moved from Brittany towards the mouth of the river Thames, approximately a hundred kilometres west of the position of the actual MCS at 12.00 UTC. At 18.00 UTC PVA values were low in the area just north of the Netherlands, the position of the MCS at that time. The system was already in a decaying state by then.
