Monday

Weather

A misty start with some fog and low cloud around gradually brightening up with some sunny spells. For those out early, then there is the opportunity to ascend through the low cloud, whose tops will be around to be rewarded by some fine views in the sunshine above the inversion. As temperatures rise, there will be an increasing chance of showers developing, especially across the Perthshire and Angus Hills and into the west of the cairngorms, where they will turn heavy and thundery with some large hail. The strong May sunshine will lead to a high risk of sunburn and sunstroke also dehydration could be an issue.

Visibility

Moderate to poor widely in the morning with hill fog, becoming good during the afternoon in the south and west where the best of the cloud breaks will be. Becoming poor to very poor in the showers.

Hill fog

Patchy to low levels at first, this gradually lifting although probably persisting over Lochnagar. Then occasional patches above 750-900m tending to lift above tops though returning in any heavier showers that develop later.

Maximum winds above 600m

Northwesterly 10mph increasing 20-25mph gusts 35mph later.

Temperature

Glens	Plus 5 to Plus 8 Celsius rising to Plus 19 Celsius.

Outlook

Wednesday

A good deal of dry bright weather with some sunshine though with an increasing chance of showers through the day especially in the north and turning cold enough for snow above 900m. Strong to gale summit north or northwesterly winds so a high wind chill.

Thursday

The northerly airstream will turn colder and stronger still so quite frequent sleet or snow showers and gales causing severe wind chill. Freezing level 800m in north and 1000m in south and falling in showers.
