Printable view Forecast issued: 1715 on Tuesday, 21 May 2013
A mostly dry and rather cloudy day, but some good sunny spells are likely, especially later.
|Heavy snow||No Risk|
|Storm force winds||No Risk|
|Severe chill effect||No Risk|
|Persistent and extensive hill fog||No Risk|
|Heavy persistent rain||No Risk|
|Strong Sunlight||Low||Often a lot of cloud around but any lengthy breaks will allow strong sunshine through.|
|Dawn to 0900||0900 to 1200||1200 to 1500||1500 to dusk|
A mostly dry day with quite a lot of cloud around initially, perhaps enough to produce the odd spot of drizzle at higher level with occasional hill fog over the peaks. The cloud should be encouraged to break-up during the day with some good sunny spells likely later, and cloud tending to lift off the peaks. Feeling cool though with moderate northerly winds.
Very good but peaks likely to be obscured at times, especially during the morning. Very poor in hill fog.
Occasional hill fog is likely above 500 metres during the morning, which should lift above the peaks by midday and onwards.
North or northwesterly 30 mph.
|Valleys||Plus 7 Celsius becoming plus 14 Celsius later.|
|800 m||Plus 5 Celsius|
|Freezing level||Above the summits.|
A much windier and colder-feeling day with some decent sunshine though in between a scattering of showers. North to northwesterly winds will become quite strong, touching gale-force over exposed peaks and ridges later in the day. Also, freezing levels will be low, and there is a chance that some showers may fall as snow over 800 metres, with a risk of hail and thunder during the afternoon.
Very good to excellent outside of showers, which should be well-scattered.
No significant hill fog is expected.
Northwesterly 45 mph during the afternoon.
|Valleys||Plus 4 Celsius becoming plus 12 Celsius|
|800 m||ZERO Celsius becoming plus 2 Celsius during the afternoon.|
|Freezing level||800 metres.|
Very windy with north or northeasterly gales possible down to low levels, with a risk of storm-force winds over highest peaks and ridges. It may also be rather cloudy with some showery outbreaks of rain, and occasional hill fog brushing the peaks. Freezing levels will be just around the peaks, so some of the precipitation could be wintry here with a risk of severe wind-chill.
A much improved day with much lighter winds than on Friday, and a chance of some good sunny spells. Just a low risk of a shower developing during the afternoon. Feeling less-cold with the much lighter winds and sunshine, but freezing levels may still be hovering only just above the peaks.
Chance of a cloudier day on Sunday with some isolated showers around, and light northwesterly winds. Freezing levels may have risen a little by this time.
