Further Details

Outbreaks of rain spreading progressively northeastwards later on Saturday and overnight into Sunday will likely be preceded by a spell of snow on its northern flank. Whilst there is some uncertainty, any snow in southern and eastern parts of England, especially at low levels, will probably be rather transient before turning back to rain. However, some significant accumulations of snow are possible across parts of Wales, the Midlands and northern England in particular, at least for a time, where 5 cm or more could accumulate fairly widely, with perhaps as much as 20-30 cm over high ground of mid and north Wales and potentially 30-40 cm over parts of the Pennines. This, accompanied by strengthening winds, may lead to drifting of lying snow.

In addition, as milder air moves northwards, snow may turn to a spell of freezing rain for a time, again more especially across parts of Wales, the Midlands and northern England, adding to the risk of ice and leading to some treacherous conditions in places. A fairly rapid thaw of lying snow is possible later on Sunday, although exactly how far north the rapid thaw will reach remains uncertain at this stage.

What should I do?

Snowy, wintry weather can cause delays and make driving conditions dangerous, so to keep yourself and others safe: plan your route, checking for delays and road closures, amending your travel plans if necessary; if driving, leave more time to prepare and check your car before setting off; make sure you have essentials packed in your car in the event of any delays (warm clothing, food, water, a blanket, a torch, ice scraper/de-icer, a warning triangle, high visibility vest and an in-car phone charger).

Keep yourself and your family safe when it is icy. Plan to leave the house at least five minutes earlier than normal to reduce your risk of accidents, slips, and falls. If making a journey on foot, try to use pavements along main roads which are likely to be less slippery. Similarly, if cycling, try and stick to main roads which are more likely to have been treated.

People cope better when they have prepared in advance for the risk of power cuts or being cut off from services and amenities due to the snow. It’s easy to do; consider gathering torches and batteries, a mobile phone power pack and other essential items.

Be prepared for weather warnings to change quickly: when a weather warning is issued, the Met Office recommends staying up to date with the weather forecast in your area.
