Snow, later showers with hail
A period of snowfall is likely for a few hours, falling to lower slopes, extensive whiteout on hills. May become sleety lower down. Tending to clear from west, later followed by showers with hail.
Fairly extensive
Shrouding the mountains most or all day, extensively during snow, to lower slopes in places. Bases may slowly rise from the west into the afternoon, then varied in and out of showers.
30%
Brief if any sun. Visibility very poor during precipitation, appalling if in snow and cloud, brief improvements lower terrain.
-2 to -4C, tending to slightly rise for a time.
Much terrain frozen following overnight frost. Becoming 300-400m perhaps slightly higher into early afternoon.
Most mountain terrain is likely to stay frozen throughout the week ahead. Sometimes freezing conditions to lower slopes, although some day-to-day variations. Wind speed and direction will vary considerably, intermittent lulls, but then a deep low is expected to affect Britain by Tuesday-Wednesday, bringing stormy conditions, perhaps widely. Further lows are likely to follow later in the week. Extensive snowfalls possible on the hills, a mix of snow and rain lower down.
