UK Braces for a Sudden Thaw and Renewed Flood Risk

A sharp turn in the weather will bring a sudden end to Britain’s recent cold snap. The frosts and biting winds of the past week are retreating, replaced by a surge of milder Atlantic air set to raise temperatures by as much as 10 degrees Celsius starting Friday.

Daytime readings, which recently struggled to reach 5C, are forecast to climb to between 10C and 14C across much of the country over the weekend and into next week. Night-time frosts will become rare, with lows generally between 5C and 9C. For Scotland, this shift is particularly notable; the country has endured its longest wait to see 12C since 1986.

The change arrives as a stubborn area of high pressure over Scandinavia finally breaks down, allowing warmer south-westerly winds to sweep across northern Europe. However, this milder pattern carries a significant and familiar downside: more rain.

Western hills are expected to bear the brunt of the heaviest downpours, continuing a prolonged period of saturation. Parts of Cornwall have now seen rain for 50 consecutive days, while some locations in Northern Ireland and Scotland have recorded half a year's average rainfall in just weeks. With the ground already waterlogged and snowmelt adding to runoff, the Environment Agency warns that flood risks across England will persist well into March.

The forecast suggests this warmer, wetter regime will dominate for at least the next fortnight, offering a reprieve from the cold but little respite from the damp.
