The United Kingdom is facing a significant weather shift as snow and plunging temperatures are forecast, potentially causing widespread disruptions. The Met Office has issued warnings for snow and heavy rainfall, particularly impacting Scotland.

A yellow weather warning is in effect for Monday and Tuesday, covering large portions of Scotland, including major cities like Glasgow, Edinburgh, and Aberdeen. Heavy precipitation is anticipated, with snowfall expected, especially in higher elevations, where accumulations could reach 10 to 20 centimeters.

This severe weather follows a period of travel chaos caused by dense fog across the UK after Christmas. Additionally, the forecast calls for 50 to 70 millimeters of rain across many areas, with some western parts of Scotland potentially experiencing up to 140 millimeters. Strong winds could further exacerbate the disruption, particularly on New Year's Eve.

The warning extends to Orkney and Shetland, where "persistent snow" is anticipated on Hogmanay, with up to 20 cm of accumulation expected in the most affected areas. Road travel is likely to be difficult due to hazardous conditions, leading to extended travel times. The transition from snow to rain may contribute to flooding, further compounding travel difficulties.

Authorities have warned of potential flooding, which may create dangerous conditions. Train and bus services also risk delays and cancellations as the weather continues to cause hazards. The Met Office has stated that significant disruption and flooding are possible, with areas most likely to be affected remaining uncertain.

Beyond New Year's Eve, the unsettled conditions may extend to southern parts of the UK, bringing the possibility of continued wind, rain, and snow. Despite some breaks in the cloud anticipated in the south, meteorologists are cautioning that the generally mild conditions are set to turn, with lower temperatures of 9 to 11C expected. The weather system is anticipated to impact New Year's Eve celebrations, particularly in Scotland.
