Surface meteorological conditions relative to the 1981-2010 average for November 2019 – March 2020: (a) mean sea level pressure anomaly (hPa); (b) surface air temperature anomaly (°C). Data are from the NCEP reanalysis (Kalnay et al, 1996). Although mild relative to the 1981

With high pressure becoming established this week, the start of April will be warm and sunny across the UK. With the area of high pressure situated to the northeast of the UK, there will be a strong breeze across the southern half of the UK through the start of the week. In windward coastal areas
