Summary for all mountain areas

In Scotland, many places dry, but a few showers moving around slowly, of snow on higher summits. Chilly, but winds light. A complex front drifts east across England & Wales - rain may well largely clear, but risk of showers following, may cluster together.

Headline for Southern Uplands

Cool. Largely dry, light winds.

How windy? (On the summits)

North to northwesterly 15-20mph for a few hours around dawn into the morning. Becoming variable, little wind by mid-morning onward.

Effect of the wind on you?

Mostly small.

How Wet?

Isolated showers

Remnants of previous rain soon clearing eastwards from Borders & Cheviots, leaving most places largely dry all day and just isolated brief hail showers.

Cloud on the hills?

Mostly very little

Cloud soon confined to higher slopes and clearing higher summits, slowest in the Cheviots.

Chance of cloud free summits?

80%, but 50% morning Cheviots.

Sunshine and air clarity?

Patchwork of sun, although obscured at times by banks of cloud at various heights. Visibility excellent.

How windy? (On the summits)

Low confidence: Mostly east or northeasterly, 20 to perhaps 35mph.

Effect of the wind on you?

Risk very blustery and chilly on higher areas.

How Wet?

Risk rain becoming persistent some hills

Uncertainty remains: Clusters of showers coming in from the northeast, perhaps a more organised area of rain pushing up from the south to set in across some hills, heaviest around Cheviots.

Cloud on the hills?

Forming extensively if rain sets in

Many hills may well start free of low cloud, but where rain develops and persists, cloud lowering to extensively cover higher terrain, particularly Borders/Cheviots. Away from rain, breaks likely to higher tops.

Chance of cloud free summits?

60%

Sunshine and air clarity?

Mostly little sun due to layers of high cloud, at times overcast and dull. Visibility very good away from rain, but poor if rain sets in.

How Cold? (at 750m)

4C.

Freezing Level

Above the summits.

Brief patches higher slopes, perhaps covering Cheviots above 700m for a few hours in morning.

Chance of cloud free summits?

80%

Sunshine and air clarity?

How Cold? (at 750m)

2 to 4C.

Planning Outlook

Generally chilly into the weekend with higher mountains near or just below freezing point, and overnight frost in many valleys, notable early-season low temperatures Highland glens. A complex low pivots eastwards on Thursday - rain focused across England, Wales & southern Scotland. Strong northerly winds follow on Friday with scattered hail showers, snow on the Munros. Pressure builds by Saturday leading to largely dry conditions and very clear air. Early next week, westerly winds are expected to return, with rain at times, low cloud and varied temperatures.
