Headline, The West Highlands

Snow, mainly at first and again by dusk. Later squally.


How Windy?

Southerly 50mph post dawn. Soon westerly 20 to 30mph, but sudden squalls by dusk with gusts over 50mph.

Effect Of Wind?

May for periods impede steady walking on the hills, and late on, walking conditions will become very difficult in squalls.


How Wet?

Occasional snow. Risk heavy hail, snow and lightning by dusk

Overnight snow, heavy western mountains will soon clear southeastwards. A break with little snow will follow, but toward dusk, sudden very heavy snow and hail showers, some with thunder will bring whiteout. Often rain lower slopes, with level to which snow penetrates varying.


Cloud on the hills?

Generally extensive across higher areas

Extensive low cloud across the region, widely below 500m southern and western hills in snow. Will improve for a few hours, with breaks to 900m, perhaps 1100m well inland. But sudden deteriorations from west later in day, with cloud below 500m in heavy showers.

Chance of cloud free Munros?

10%

Sunshine and air clarity?

Glimpses of sunshine. Good visibility at times - but intermittently very poor, and suddenly near zero where in snow and cloud.


How Cold? (at 900m)

-2C

Freezing level

Up to 650m on western summits, but much lower elsewhere. Most terrain frozen from glens upward particularly inland, and in many areas icy.


Planning Outlook for all mountain areas from Saturday, 25th May, 2013

Generally chilly over the coming week, with the freezing level remaining intermittently below highest summits. Overall showery, although early next week, areas of persistent rain will affect most mountain areas, with north and northwest Scotland probably having least rainfall. Fresh snow will intermittently fall on higher, mainly Scottish summits. Upland gales may well be extensive on Monday and Tuesday, after much lighter winds this weekend, and before a further few days of much lighter winds. Cloud base will often be above most summits, and visibility often excellent or superb.
