My guess is that the pressure sensor at the lighthouse is reading at least 0.5 hPa too high.
The questions is how high will it go?
Told you it was cold!
Just how unusual was the intensity of the D-Day low over the British Isles?
It’s no wonder that the weather in eastern parts of the UK was so dry during April 2019. A positive anomaly of 10 hPa just to the west of Norway and a negative anomaly of 7 hPa just to the southeast of Cape Farewell in the south of Greenland produced a negative zonal flow across most of central and northern Europe.
