Summary for all mountain areas

Heavy rain sweeps northeast across England and Scotland through morning: persistent falls, locally torrential with risk thunder, particularly west Scotland early hours. Rain soon clears Wales, more widely by midday, bright skies follow, trending cooler and showers developing. Widely windy, gales in Scotland.

Headline for West Highlands

Early severe gales and heavy rain, afternoon sun and showers

How windy? (On the Munros)

South-southeasterly 45 to 60mph to start, or stronger over Ben Nevis, gusting 70-75mph over high tops. Shifting southerly and lessening, mostly 45-55mph, strongest west, particularly southern islands.

Effect of the wind on you?

Challenging walking conditions, frequent buffeting knocking you off balance, mobility at times difficult, particularly early in the day. Significant wind chill despite mild temperatures.

How Wet?

Early heavy rain, afternoon showers

A band of heavy rain moves northeastward across the region from overnight and into morning, local torrential falls with risk an odd flash of lightning. Rain will rapidly break up, followed by a dry window, then showers drifting from the southwest afternoon.

Cloud on the hills?

Early cloud breaks to and above tops, later returning in showers

Extensive cloud over the hills in early rain, then lifting rapidly and clearing toward upper slopes, well-broken for a time off high tops. Banks will return at times, increasingly frequent with lower bases as showers return later.

Chance of cloud free Munros?

Rising to 60% for a time

Sunshine and air clarity?

Intermittent sun breaking through. Poor visibility in rain, then improving, but may be quite hazy near coasts, particularly southern islands.

How Cold? (at 900m)

Humid 12C from dawn, locally warmer inland. Will vary but generally dropping through the day to finish near a fresher 8 or 9C. Feeling near/below freezing in the wind.

Freezing Level

Above the summits.

Rising to 60%

Planning Outlook

Fresher, blustery south-southwesterlies from overnight Wednesday persist on Thursday: showery in the west early but trending drier and brighter widely. A new frontal system approaches late Thursday and overnight, then Friday will be a wetter day again; rain quite frequent with extensive cloud for many and quite blustery. On Saturday, higher pressure begins expanding from the south, increasingly settling the weather in England and Wales; temperatures generally mild, some cool nights when skies are clear, also sometimes feeling humid. The following week remains mixed, some settled windows in England and Wales with bright breaks east, but more often windy, particularly Scotland with periods of rain, the wind and rain expanding more widely at times.
