Freezing rain is expected to result in the rapid development of widespread ice, with very dangerous travelling conditions likely.
Heavy freezing rain is expected to develop during Saturday. This will result in the rapid formation of widespread ice on roads, pavements, trees and other structures. Freezing rain is rare in the United Kingdom but when it does occur the impacts can be very severe. This is due to the fact that it can form very quickly, it can be difficult to see and is incredibly slippery. Some sleet and snow is possible over the very highest ground and the freezing rain may also be followed by a spell of sleet and snow as the precipitation clears from the west. The freezing rain and sleet and snow will be accompanied by strong southeasterly winds which will pose an additional hazard to travel, in particular over high ground.
Heavy snow and blizzards bringing disruption to travel and infrastructure.
A period of prolonged and heavy snow is expected to develop through Saturday morning, before clearing from the west through Sunday morning. 5-10 cm of snow is likely widely across the area, whilst some areas could see 20 cm, perhaps as much as 40cm over higher ground. Strong south-esaterly winds will lead to temporary blizzard conditions as well as drifting of lying snow.
Heavy rain and strong winds across parts of Northern Ireland , south-west England and south Wales.

The wettest areas could see 30 to 50 mm of rain in 6 to 12 hours, while winds could gust to between 50 and 60 mph, especially in exposed coastal areas. The combination of these factors on a busy shopping weekend, may add to potential disruption.
The area which may be affected by severe weather has been expanded further south.
