Overview

• WXCharts using MetDesk’s GEFS guidance shows a credible chance of snow mainly over the Scottish Highlands around October 20–22, with some runs shifting toward October 24–25.
• Higher ground in northern England, including the Pennines and uplands between Newcastle and Manchester, features small patches of potential wintry showers in the same window.
• Some projections indicate localized totals up to about 10cm in parts of northern Scotland, with one run suggesting up to 18 hours of snow in sections of Aberdeenshire on October 24–25.
• Most of the UK and Ireland are shown as too mild for snow in these maps, with rain more likely across England and Wales while southern areas stay largely snow-free.
• Official guidance highlights high pressure keeping conditions settled at first before a possible shift to more changeable, low-pressure-driven weather later in the month, with temperatures near seasonal norms.
