Effect of the wind on you?

Nuisance wind, walking impeded in exposure, a deteriorating trend, becoming strenuous late in the day and feeling chilly.

Some patchy rain around the Solway and Cheviots early, soon clearing. Likely dry for several hours, then showers begin affecting western areas, snow on high terrain, well-scattered further east

Cloud on the hills?

Mostly clear, occasional banks on high terrain

At dawn, a layer of cloud caps the high terrain from the Solway to the Cheviot, this soon clearing south leaving ragged patches of cloud that dissipate with time. The hills then mostly clear, banks grazing high terrain during afternoon showers; east hills may stay clear.

Chance of cloud free summits?

Rising to 80% east, 50% west

Sunshine and air clarity?

Mostly sunny early (except south/east), fair weather cloud building. Good visibility, some haze, and suddenly poor where showers occur.

Varied mostly over western tops

Patchy cloud capping higher slopes mostly toward the west in the morning, lifting increasingly above the tops by middle of the day.

Chance of cloud free summits?

40% rising to 80%

Sunshine and air clarity?

Patchwork of cloud and sun, best in east in morning. Visibility often very good, but reduced at times to briefly very poor in showers.

How Cold? (at 750m)

-1C rising to +1 or 2C afternoon. Wind chill feeling like -10 to -15C.

Freezing Level

600-700m in morning, plus frost in sheltered valleys around dawn, rising just above freezing to highest tops afternoon.

Planning Outlook

Thursday starts chilly with clear skies for many, snow then rain moves into western areas with time. Strong northwesterly winds prevail as the weekend starts, brining cooler temperatures and a mix of showers and sun across most areas, the showers likely snowy to middle elevations with some hail mixed in. The cool, spring-like conditions will allow showers to become heavier and more widespread in the afternoon. Sunday into next week sees high pressure southwest of the country, producing drier weather with sun breaks, a trend towards milder temperatures too, but several low pressure systems to the north draw bands of rain eastward, mostly affecting Scotland, occasionally northern England and Wales. A risk of cooler northerly winds re-establishing later in the week, though detail is uncertain.
