The cold snap that had the United Kingdom recently shivering will be replaced by a turn to milder, unsettled weather this weekend and into next week.
Instead of high pressure directing cold air down from the north into the U.K., as was the case during the cold snap, a change in the weather pattern will open the door for the return of milder air from the south.
"An area of low pressure that is east of Greenland will be swinging toward the North Pole and bringing an active storm track to central and northern Europe," AccuWeather Meteorologist Tyler Roys said. "That will allow mild air to pour in."
The mild surge will send temperatures this weekend to their highest levels since late December across the U.K.
Sunday will be the warmest day of the weekend with highs generally in the lower teens C (lower to middle 50s F) outside of the higher terrain. Such highs are 8-10 C (15-20 F) higher than during the cold snap.
Temperatures will then average above normal for most of next week. The only exception may be far northern Scotland, where temperatures will be closer to normal. Average high temperatures in late January generally range from 5-8 C (lower to middle 40s F).
The mild air will be accompanied by an active storm track, which will send unsettled spells to the U.K. beginning this weekend.
Steady rain will spread across Wales and England, as well as grazing Northern Ireland, Saturday afternoon and night. The rain around London will hold off until after sunset.
Odd showers will persist across western England, Wales, Scotland and Northern Ireland on Sunday as eastern England dries out.
Back-to-back storm systems will follow for Monday and Tuesday with the latter day's system expected to be the stronger and potentially more impactful of the two.
Scattered showers on Monday will give way to a steadier rain on Tuesday. The rain could be heavy enough to trigger flash flooding, especially along the western slopes of the higher terrain.
"There is a chance on Monday for gusty winds to approach 50 mph (80 km/h) in Wales, northern England, Scotland and Northern Ireland," Roys said. "But there could be more widespread gusts around 50 mph (80 km/h) on Tuesday.
Additional storms will likely bring more bouts of rain and gusty winds to the U.K. in the final days of January.
