Forecasters are predicting snow in Letchworth and the rest of the UK this weekend.

The Met Office has issued a yellow weather warning from 12noon on Saturday 4 January until 9am on Monday 6 January.

Meteorologists are warning "heavy snow" may cause some disruption.

There is a small chance that power cuts will occur and other services, such as mobile phone coverage, may be affected.

There is a slight chance that some rural communities could become cut off.

There is a chance of travel delays on roads with some stranded vehicles and passengers, along with delayed or cancelled rail and air travel.

Dan Holley is a deputy chief forecaster for the Met Office. He said: "An Atlantic frontal system is likely to move across parts of central and southern UK through the weekend. With milder, moisture-laden air engaging with the cold conditions already in place this may bring a spell of snow in some areas, before possibly turning back to rain in the south.

"At this stage there is a fair amount of uncertainty over exactly which areas will see disruptive snow, with parts of Wales, northern England and the Midlands most likely to see some impacts.

"Here we could see 5cm or more in quite a few areas, and perhaps as much as 20-30cm over high ground, including Wales and the Pennines. Coupled with strengthening winds this could lead to drifting, making travelling conditions difficult over higher-level routes in particular.

"We've currently issued a Yellow warning for snow covering a large part of England, Wales and southern Scotland to cater for possible disruption over the weekend, but it's quite likely this will be refined over the coming days as confidence in the forecast increases. So it's worth keeping up to date with the latest warnings."
