A weather system will cross to the south of this region early on Friday. This will bring rain to many areas but snow is likely over some of the higher ground, such as the Pennines and Southern Uplands, and rain may turn to snow at lower levels before it clears eastwards. The snow may be heavy in places, possibly giving 2-5 cm at low levels and maybe 10 cm or more above around 200 m. Following clearance, there is also the risk of widespread ice on untreated surfaces in time for the morning rush hour.
The public should be aware of the potential of disruption to travel and also of hazardous driving conditions. This is an update to the warning issued on Tuesday to move the risk of snow away from the central belt of Scotland and into northern England.
Chief Forecaster’s Assessment
An area of low pressure, currently forming in the mid-Atlantic, is likely to run quickly northeast somewhere across central Britain early on Friday. On its northern flank, cold air may be drawn into the system, with a band of rain across southern Scotland and northern England possibly turning to snow, even to low levels, clearing skies then quickly leading to icy conditions late in the night.
This is a complex development and details may yet change. Therefore this alert is likely to be updated again on Thursday, as confidence grows in the track and timing of this system.
