Additional weather information
Meteorologist's view
Breezy and gusty conditions at times will make for fairly arduous walking on exposed terrain with buffeting of clothing. Balance may be affected at times. UV levels will be moderate despite the high cloud so suitable protection may be required.
Weather
Mostly dry throughout the day but there may be the odd spot of rain from a light shower in the early hours. Widespread low cloud in the morning. Low cloud lifting and breaking through the morning to leave some bright spells or hazy sunshine in the afternoon. Widespread low cloud feeds back in through the evening.
Chance of cloud-free hill tops
20% or less in morning and evening. Rising to 75% in afternoon.
Low cloud and visibility
Widespread cloud down to 300-500m in the morning and again in the evening. This gradually lifts and clears in the morning to allow summits to be mostly clear with good visibilities and the cloud layer above the tops.
Ground conditions
No recent ground conditions report available.
Mountain weather information
Weather
Cloudy in the morning with some showery outbreaks of rain pushing north, perhaps heavy at times. Low confidence in details through the afternoon but most likely cloudy with showers or longer spells of rain, potentially heavy and thundery and turning quite persistent for a time.
Chance of cloud-free hill tops
20% or less at first, rising 40% by midday. Likely little chance through the afternoon and evening.
Maximum wind speed expected
East or Southeast veering northeast later, 20-30mph.
Temperature
- At 800m Plus 9C to plus 11C.
- Glen Plus 13C rising to plus 19C by day.
- Freezing level Above summits.
Low cloud and visibility
Widespread cloud down to 300m or so in the morning, but the very highest summits may poke out above the cloud layer. This lifting somewhat in the morning to allow some limited clear spells, most likely in the west. Widespread low cloud likely to return through the afternoon and evening. Visibilities falling poor in hill fog and outbreaks of heavy rain.
Ground conditions
No recent ground conditions report available.
Mountain weather information
Fri 28 Aug
Low confidence. Likely cloudy with showers or longer spells of rain, heavy at times.
