Additional weather information

Meteorologist's view

It will be a chillier start than recent days, so pack an extra layer if heading out early. Thereafter, it will be pleasantly mild for walking without being overly warm. However, recent rain will mean that conditions under foot will still be very wet and slippery in places.

Weather

Generally dry with bright or sunny spells throughout today. Isolated light showers are possible, mainly in the west.

Chance of cloud-free hill tops

90%, some early low cloud or mist will soon lift with fair weather cloud remaining above summits throughout today.

Low cloud and visibility

Some temporary poor visibility as any overnight low cloud or valley mist lifts this morning. Otherwise, good or excellent visibility with distant hill clearing seen.
