Light snow fading Peak District and Pennines, low cloud persists here. Generally dry Wales but increasingly windy.

How windy? (On the summits)

Variable or northerly 20mph, easing for a time but then increasing northwesterly 30mph afternoon, nearer 40mph up to dusk.

Effect of the wind on you?

Prepare for considerable wind chill becoming more significant later and more challenging walking conditions by later afternoon.

Snow affecting central and eastern hills from before dawn, soon starting to ease and fade out to leave substantially dry conditions. From dusk, a little rain moves onto west coastal hills, snow above 600m.

Cloud on the hills?

Varied cloud banks may linger

Varied extent of low cloud, covering some lower slopes at first. Tending to rise, but some lingering areas of cloud around the hills, may fill in again over western hills for periods.

30%

Patchy rain/drizzle affecting high western hills much of the day, the best chance of dry periods in east Wales. Rain sets in for a few hours, then breaking into scattered showers.

Cloud on the hills?

Fairly extensive

Cloud shrouds high terrain and slopes to the west and south down to the middle slopes most of the day. Cloud at times well broken and higher bases towards mid-Wales/Black Mountains, but extensive here too during rain.

Chance of cloud free summits?

40%

Sunshine and air clarity?

Mostly cloudy but some bright/sunny breaks will come and go, best east. Variable visibility, good out of cloud and rain, but some haze too.

How windy? (On the summits)

Southwesterly 30 to 40mph, briefly lowering in morning, but soon increasing again, toward dusk risk 50mph.

Effect of the wind on you?

Strenuous walking conditions, making balance challenging on exposed ridges, widely difficult at dawn and again later.

How Wet?

Rain and drizzle

Rain on and off, persistently drizzly at least, more constant rain for periods in west, may become heavier with time. Patchier eastern mid-Wales.

Cloud on the hills?

Extensive

Blanketing the hills all day, rarely above 300-400m west and southwest areas. Slightly higher eastward, and furthest east in mid Wales, bases toward 600m at times.

Chance of cloud free summits?

10%

Sunshine and air clarity?

Overcast and dull. Hazy, visibility widely poor in rain.

How Cold? (at 750m)

5 or 6C. Where exposed to stronger winds on tops, feeling like -5 to -7C.

Freezing Level

Above the summits.

Planning Outlook

Toward the weekend, a switch to southwesterly winds, bringing milder conditions - lifting above freezing to tops in England and Wales with substantial thawing, and generally higher freezing levels in Scotland; periods of thawing to Munro summits will occur but also further snowfall and refreezing on higher terrain during the day-to-day variability of precipitation and freezing levels onward into early next week. Often windy with periods of upland gales. Some spells of heavy rain over all western hills and low cloud frequently covering the hills.
