Forecasts have revealed the date when Britain could see its first snow this autumn, as temperatures decrease. Weather maps generated by WXCharts highlight a small chance of snow later in September, with a small area of northern Scotland potentially seeing snowfall following a wave of heavy rain just one day earlier.
Rain and snow forecast for late September
On Sunday, September 20, the maps show a sweeping band of rain moving in from the northwest Atlantic, set to blanket Scotland, Northern Ireland and northern England. While the rain will reach approximately 1.5mm per hour, some areas could see as much as 7.5mm per hour.
Following this, on Monday, September 21, the maps show the potential for snow in a small part of northern Scotland, marking the first potential snowfall since the world's hottest month on record. A small area of northern Scotland is predicted to see snowfall of up to 2mm per hour. Temperatures across Scotland are expected to remain below 10C that day.
Met Office outlook for mid-to-late September
The Met Office long-range forecast states that the weather between September 14 and September 23 will "remain changeable, with occasional rain or showers arriving from the North Atlantic, most frequent across northern and western parts of the UK, where some strong winds will also be possible at times".
It adds: "However, there will also be some reasonable dry and more settled periods, especially across southern areas.
"Later in the month, high pressure may become more dominant in the vicinity of the UK, perhaps bringing more widely settled conditions for a time, especially away from the far north. Temperatures for the period as a whole will probably be close to average overall, but there is scope for some rather warm days at times, along with occasional relatively cool nights."
