Today's Forecast
Windy, walking impeded
Blustery conditions enough to give buffeting on higher terrain or affect balance on exposed ridges. 25 to 40mph.
Frequent or persistent rain
Steady rain fairly persistent, occasionally heavy, rather wet underfoot.
Poor visibility
Murky conditions with areas of fog shrouding the hills, making navigation challenging. Map and compass essential.
Chilly
Air temperature typically 0 to 5C on higher summits. Feeling distinctly chilly on tops when stationary or where exposed to wind. Take appropriate layers.

Windy for many, gale force gusts in Scotland, most powerful west. Snowing south and east Highlands (whiteout on high terrain), only patchy west; rain to lower slopes at first. Extensive cloud from southern Scotland through England and Wales and often raining, heaviest south and west slopes. Lighter wind southern Pennines.
Headline for Eryri / Snowdonia National Park
Extensive cloud and often raining; blustery in exposure
How windy? (On the summits)
Southwest or southerly, in the range 20 to 25mph, rising to 30-35mph for several hours around midday, strongest speeds over high tops and into western mid-Wales.
Effect of the wind on you?
Ease of walking impeded on higher terrain most of the day, likely strenuous for several hours, requiring more effort to maintain stability, and feeling chilly.
How Wet?
Often raining
Rain nearly persistent onto western slopes and frequently heavy, often passing east as well, though a few drier periods as possible in east Wales.
Cloud on the hills?
Extensive, lowest west
Most hills persistently cloud covered above 500 to 700m; perhaps breaks toward 800m Carneddau and east Wales.
Chance of cloud free summits?
Less than 10%
Sunshine and air clarity?
Little or no sun. Extensively cloudy, some moments of good visibility in east Wales, hazier and cloudier with rain west.
How Cold? (at 900m)
3 or 4C. Wind chill feeling like -5 to -8C in exposure.

Patchy rain affecting most mountains throughout the day with some extended rainy periods possible, most likely in the west. Precipitation will fall as sleet/snow above 800m.
Cloud on the hills?
Fairly extensive
High terrain stays shrouded most or all day, often above 700m. Cloud will variably lower to the middle slopes or locally the lower slopes, though also higher breaks are possible too.
Chance of cloud free summits?
20%
Sunshine and air clarity?
Some bright glimpses possible but often cloudy. Variable visibility, often poor in rain.
How Cold? (at 900m)
1C most of the day, lowering to 0C around dusk, dropping further overnight. If strongest winds occur, feeling like -10C.

How windy? (On the summits)
Northeasterly, gradually shifting northerly, 30-45mph.
Effect of the wind on you?
Arduous walking in exposure, accurate foot placement and balance constantly challenged. Severe wind chill.
How Wet?
Morning snow trends showery
Morning snow fairly widely soon trends lighter and moves southward, breaking into a more showery regime, most regular north of the A5; may remain snowy towards mid-Wales for longer with rain up to 400m.
Cloud on the hills?
Extensive early, lifting and breaking
Cloud shrouds most mountains from 500m up early in the day. A lifting trend with time, perhaps to just the higher summits by afternoon with a chance of some summit breaks late in the day - timing of improvement is uncertain.
Chance of cloud free summits?
Rising to 50%
Sunshine and air clarity?
Overcast early, some glimpses of weak sun later. Very poor visibility in snow, improving as snow eases and cloud lifts.
How Cold? (at 900m)
-3 or -4C, trending cooler with time. Feeling like -20C or cooler exposed to direct wind.
Freezing Level
400m, some variability around this height.
Planning Outlook
Becoming colder for all areas during the transition into the weekend, with much mountain terrain frozen again to increasingly lower elevations - soonest toward the north and east of Scotland. A widespread frost is likely early on Saturday. Northeasterly wind will be dominant - the distribution of snow showers shifting with time from eastern hills to more north-facing mountains, particularly Scotland. Away from showers later in the week, brighter than recently with sunshine and clearer hills, most likely later Friday and Saturday. Unsettled weather returns on Sunday, with a more active week likely to follow, dominated by west-to-northwesterly winds - most precipitation in the west with some freeze-thaw cycles in central and southern areas.
