Cold air over parts of Canada is pushing southwards, while much milder air lies further south. This sharp contrast is strengthening the jet

, has been recorded twice in 1958 and 1971. Yet January’s warmth contrasts sharply with its capacity for severe cold. The lowest UK January temperature on record was –27.2°C, logged at Braemar, Aberdeenshire, on 10 January 1982. In England, the lowest minimum was –26.1°C at Newport, Shropshire, also

. The storm’s track is uncertain, but it’s likely to run along the south coast, bringing a sharp boundary between rain and snow. A number of weather warnings, including amber warnings for wind and snow, have been issued.  Computer models show a number of possible tracks. The difference between rain
