High for favourable conditions dominating Tuesday, then medium for the timing of onset and clearance of the rain Wednesday and Thursday respectively.
Harmful UV levels from sunlight increase with altitude giving a greater risk of sunburn and eye damage, even on some overcast days. On breezy days, the cooling effect of wind on exposed skin may disguise any feeling of sunburn until it is too late. If there is snow cover, glare increases the effect of UV rays especially on the eyes. It is advisable to wear sun block, protective clothing such as a long-sleeved top and hat and have good quality eye protection.
Favourable conditions for most of Tuesday, then turning unsettled from Wednesday.
