shading represent values above the 80th (Warm) and 90th (Hot) percentile, respectively; regions shaded in light and dark blue indicate values below the 20th (Cool) and 10th (Cold) percentile, with respect to the 1981-2010 climatology. The data used in this map are from the NOAA Climate Prediction Center

and Saturday, some of which could be thundery in nature. Both wind and showers are expected to ease on Sunday.   Further south, there will be plenty of dry and fine weather around in the weekend, with temperatures likely to peak at around 24C in the southeast. Some light showers are possible

Height of base: 1,200 - 6,500 ft Shape: cumuliform "lump" at base Latin: stratus - flattened; cumulus - heap Precipitation: light What are stratocumulus clouds? Stratocumulus clouds are low-level clumps or patches of cloud varying in colour from bright white to dark grey. They are the most common

conditions. There will be spells of cloud and light rain at times in the north west as weak fronts move in but they will quickly dissolve. Temperatures will gradually rise through the week, with an expected high of 24°C, possibly 25°C, by Thursday. These temperature highs are expected to be in parts

in 17 people being killed along with 4 horses. The thunderstorms across South East England slowly died away during the evening and here it turned rather misty. Winds generally were light and from the southeast. Temperatures were above the late May average generally and very warm, locally hot

Although there will be a bit of a split in the weather over the coming days, much of England and Wales will see bright and dry conditions with sunny spells. Temperatures will reach the mid 20˚Cs across the south where it will feel quite warm with light winds. Further north, Scotland, Northern

are, by definition, rare, which means we have relatively few observations, especially in light of our changing climate. This means it is difficult to estimate the current chances of extreme weather and climate events. To overcome this, the CSSP China project pioneered a technique using the Met

months there is ~95% chance of La Niña continuing. The latest NOAA Climate Prediction Centre / NCEP statement (PDF) states that: “La Niña is expected to continue through the Northern Hemisphere winter 2020-21 (~95% chance during January-March), with a potential transition to ENSO-neutral during

of view one of the key things in his book is a study of optics; in this case reflection and refraction. By experimenting with light Magnus realised that the only way a rainbow could be formed was if raindrops were spherical. Considering the nature of white light itself was not understood until the work
