How windy? (On the summits)
Southerly, some uncertainty of peak speed, in range 30mph to possibly 50mph, at least in gusts around highest tops.
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
High uncertainty of detail, but expect clusters of heavy showery rain tracking northeastward throughout the day. Some drier windows possible, but risk sudden downpours, thunder and lightning.
Cloud on the hills?
Varied, extensive around rain
Fairly extensive cloud banks in the morning, to some lower slopes especially in west. Tending to lift and break, but more persistent near Solway. In rain, lowering, filling in again, low ragged patches.
Chance of cloud free summits?
40%
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.
How Cold? (at 750m)
13 to 16C, warmest Cheviots; small variation all day. Still rather humid. Feeling cooler directly in wind.
Freezing Level
Above the summits.
Planning Outlook
Exceptionally warm and humid most mountain areas until later Friday; valley temperatures approaching the low-to-middle 30s in England and Wales, with hill temperatures approaching the mid-to-high 20s. Scotland will be slightly cooler, though temperatures will still reach the low 20s on many slopes. A risk of extended torrential thunderstorms on Friday afternoon in northern areas. Thunderstorms may continue in the north on Saturday as well, but progressively less warm as the weekend goes: fronts begin to come in off the Atlantic, bringing a strengthening wind and bands of rain and low cloud, particularly affecting western mountains. Into next week, Atlantic westerlies will dominate with mixed weather.
