These charts of surface pressure, from analysis (T+0) to the 84-hour forecast (T+84) are produced daily around 0730 UTC.
A deep area of low pressure is centred over the Baltic
Sea with various fronts associated with it, including an
upper cold front over Eastern Europe. This is marked with
un-shaded triangles and marks the same differences in air
mass but higher in the atmosphere. Tight isobars in the
North Sea indicate very strong winds.
