How windy? (On the summits)
Southeasterly 25 to 35mph, gusty in places around major summits and some western downslopes.
Effect of the wind on you?
Strenuous walking in exposure, gusty areas making balance difficult at times. Considerable wind chill.
How Wet?
Rain fairly persistent
Some uncertainty, but rain likely to affect much of the region throughout the day, may give some steadier or heavier falls particularly south and eastern areas, mixed with drizzle at times.
Cloud on the hills?
Extensive
Shrouding the hills likely all day, lowest cloud bases on southern and eastern slopes, may fill in to lower slopes at times. Higher bases to 500-600m in west, local breaks west mid-Wales if drier.
Chance of cloud free summits?
10%
Sunshine and air clarity?
Overcast and dull, poor visibility fairly widely, but locally brighter toward Cardigan Bay.

Above the summits.
Planning Outlook
A slack pressure pattern to start the new week over Scotland, maintaining varied low cloud and fog. Lowering pressure to the south and an increasing easterly wind for England & Wales. Rain pushes into Wales on Tuesday, reaching the south Pennines with time, persisting in these areas into Wednesday, but very little extending further northwards. Into the second half of the week, a switch to a colder northerly flow will likely drop the freezing level to 800m increasingly widely for Thursday-Friday, plus frost on low ground. Some snow showers on northern Scottish mountains, but largely dry weather elsewhere. During next weekend, a shift to a less cold Atlantic influence - a changeable mix likely into the following week.
