Counties facing snowfall on Wednesday – as flurries of wintriness sweep north of the border and cover Scotland – have been laid bare by new weather maps and charts. WX Charts maps, using Met Desk data, show a big downturn in conditions tomorrow.

Wednesday could see snowfall – measuring up to a high 10cm – hit Scotland. The Highlands is most at risk, with counties covered by purple, white and grey blotches (which show snowfall) including Invernesshire, and Highlands counties.

The worst of the weather will start from 6am and could linger til 9pm. Inverness, Aberdeenshire, Sutherland, Caithness, Nairn, Ross and Cromarty, and parts of Argyll and Moray are most at risk.

Issuing a verdict on what lies ahead into early November, after the prospect of the first significant snowfall of the year, the BBC Weather team has spoken out.

Its November 3 to November 9 outlook says: “There is low confidence in the forecast the following week not least because of uncertainty about where the remnants of ex-hurricane Melissa will go.

“After moving sluggishly around the Caribbean, it should eventually pick up speed and run north-eastwards across the Atlantic, and could end up somewhere near western or north-western Europe as it get mixed up with mid-latitude low pressure systems.

“If that’s the case, then we can expect the unsettled weather to continue, with further periods of rain, some heavy, and occasionally strong winds. Rainy periods may be interspersed with brighter but showery days.

“It will, however, be mild for early November, with temperatures above or well above average.

“There may be a chance of some drier conditions later in the week, and if Melissa’s remains happen to head farther north then there’s a world in which more of the week could be drier.”

Netweather TV adds: “The ECM and UKV global model show a secondary low over northern Britain early on Saturday after the first low stays to the west of the UK on Thursday.

“Something to watch later this week with milder but potentially very wet and windy conditions.”
