the low passes over Scotland and winds could sharply fall for a time before quickly strengthening again. Blustery wintry showers will remain through Saturday as the low moves away.

A deeper look at the meteorological drivers behind the change shows a strengthening jet stream, influenced by a sharp temperature gradient across North America, is helping to steer low pressure systems toward the UK. This will bring more unsettled weather
, rather than dropping sharply. Looking ahead, model ensembles suggest a gradual decline in temperatures, with the most noticeable cooling in eastern areas. Further west, the picture is less clear, as low pressure systems could bring milder air from the south or southwest. After an exceptionally mild spell
over the higher ground, but much of this will turn to rain as milder air moves in. Winds will strengthen through the morning with the strongest gusts in southwestern parts of Scotland. There will be a time in the middle of the day when the low passes over Scotland and winds could sharply fall
, but the north-east stayed dry. The 20th was cold and bright in the north and south-east, cloudier elsewhere, with some showers in Cornwall. There was a sharp frost in the south-east on the 21st, followed by a sunny day, but cloudier milder weather spread from the north-west. Rain and hill snow spread south

Instead, temperatures will likely return closer to average. Uncertainty and the role of high pressure
square km below the 1981-2010 average. Notably, extent dropped sharply at the end of March, leading to a period of record low extent lasting until late April. This occurred in association with strong southerly winds in the Bering Sea and Barents Sea regions, and rapid sea ice retreat in these areas
could bring heavier rain further west. A colder turn: Arctic air and the risk of snow As Storm Benjamin moves away, it will usher in a change in wind direction, drawing in a northerly flow and bringing cold arctic air across the UK. This will cause temperatures to drop sharply, with brisk, strong
