Summary for all mountain areas
Starting hot and humid again, a cooling trend afternoon. Thundery showers for many in the morning, tending to clear in Wales. Afternoon thunderstorms and torrential rain in north England and Scotland, risk of localised flash flooding near heaviest downpours. Driest south Wales and Northwest Highlands.
Headline for West Highlands
Very warm; thunderstorms, risk of flash flooding
How windy? (On the Munros)
Variable 5-15mph through morning and into afternoon, trending southeasterly afternoon, speeds rising somewhat, between 10 to 20mph but with some powerful gusts around thunderstorms, later to 30mph.
Effect of the wind on you?
Mostly small but a rising risk of buffeting gusts around thunderstorms which may briefly affect stability.
How Wet?
Thunderstorms, prolonged torrential downpours
A scattering of showers, heavy bursts with risk of thunderstorms too. Through afternoon, rising risk of showers clustering together into prolonged torrential downpours with hail and lightning; rapidly rising rivers and streams with flash flood risk.
Cloud on the hills?
Fairly extensive and variable
Most slopes shrouded above 700-800m most of the day, lower banks likely early. A few breaks here and there for a time, and perhaps some local clear spots between cloud banks, but then becoming extensive to at least middle slopes as rain sets in more widely.
Chance of cloud free Munros?
20%
Sunshine and air clarity?
Rare glimpses of weak sun, becoming overcast and murky. Variable visibility, often poor due to cloud and rain, locally better, becoming hazy far south.
How Cold? (at 900m)
15 to 17C, or starting a degree milder in the far south. May slightly rise, but trending towards 15C widely in the afternoon as rain sets in. Very humid.
Freezing Level
Above the summits.

How windy? (On the Munros)
Southerly, 20-30mph, peak speeds approaching 45-55mph afternoon, with a risk of stronger speeds along the coast.
Effect of the wind on you?
Expect strenuous walking conditions, more challenging in places with buffeting gusts knocking you off balance.
How Wet?
Bursts of rain, risk thunder
Clusters of heavy showery rain likely tracking northeastward, increasing risk of more frequent bursts developing widely, sudden downpours, thunder and lightning. An early drizzle in hill cloud.
Cloud on the hills?
Often covering hills, some low banks
Fairly extensive cloud banks in the morning, to some lower slopes in southern areas. Some rise of base, local breaks mainly toward north Lochaber; clearer north aspects in general. In rain, lowering, filling in, low ragged patches to forest canopies.
Chance of cloud free Munros?
20%
Sunshine and air clarity?
Brief glimpses of sun, mainly north. Misty many slopes in morning. Visibility improving for a time if dry below cloud, but poor around rain, murky in places.
How Cold? (at 900m)
12 to 14C, small variation all day, then may lower overnight from west. Still rather humid. Feeling cooler directly in wind.
Freezing Level
Above the summits.

How windy? (On the Munros)
Southwesterly 20-25mph, approaching 30mph Lochaber and later more widely 30-40mph, stronger gusts possible.
Effect of the wind on you?
May be fairly small at first, but walking increasingly impacted, likely at least strenuous later and feeling chilly.
How Wet?
Light patchy rain, mostly west
Light patchy rain drifts onto the hills from the southwest, dry windows too, particularly inland. Some steadier falls for a few hours around dawn with heavier moments.
Cloud on the hills?
Fairly extensive early, many hills clear afternoon
From dawn, fairly extensive to the middle slopes, notably during rain where ragged patches form lower. Bases lift with increasing breaks as noon approaches, probably just caps over high tops afternoon, or more cloud coastal high terrain.
Chance of cloud free Munros?
20% rising to 60% afternoon
Sunshine and air clarity?
Mostly cloudy morning, breaking to a patchwork of cloud and sun afternoon. Very good visibility, a haze offshore Lochaber.
How Cold? (at 900m)
7 to 9C; later a degree cooler Mull and northward. Feeling near/below freezing in later wind.
Freezing Level
Above the summits.
Planning Outlook
The transition away from the exceptionally hot and humid weather begins on Saturday as wind shifts southwesterly and strengthens. Rain and thunderstorms may continue on Saturday as well as perhaps early Sunday, but a front will push east across the country on Sunday, followed by fresher, sunnier weather; patchy rain will likely linger here and there, notably northwest Scotland. Westerly Atlantic patterns dominate next week: high pressure south and low pressure north will bring alternating settled and unsettled windows. Wind generally on the strong side, mild to sometimes warm temperatures, and periods of rain punctuated by bright sunshine. North and western areas most vulnerable to extensive cloud and prolonged rain.
