How windy? (On the summits)
Easterly 25-35mph, gusty over high terrain; an easing trend, possibly towards a lull for a time with variable wind.
Effect of the wind on you?
Strenuous walking in exposure to start the day with wind chill; effect may become fairly small but detail uncertain.

Some morning snow
Snow affecting central and eastern hills from before dawn, soon starting to ease and break into odd patches, likely dry by afternoon.
Cloud on the hills?
Fairly extensive early, likely improving
Fairly extensive over high terrain early in the day, bases to the middle slopes near and east of Brecon. An improving trend is likely, though variably returning to high tops, greatest risk in the east.
Chance of cloud free summits?
50%
Sunshine and air clarity?
A cloudy start, sun breaking out with time, best in the west. Improving visibility, some haze around.
How Cold? (at 750m)
-1 or 0C, some variability, may locally reach +1C.
Freezing Level

Planning Outlook
Much terrain frozen midweek, frost into valleys and glens. Strengthening wind on Wednesday with considerable gustiness, gales likely in Wales; possible snow moving into Wales as well, which may move further north but detail is uncertain. Late in the week and through next weekend, a switch to southwesterly winds is expected, bringing a change to milder conditions - lifting above freezing to tops in England and Wales, and generally higher freezing levels in Scotland; periods of thawing likely to Munro summits, though some further snowfall at times on higher Munros during periods of cooler northwesterly wind. Rain most frequent over western hills. Generally windy with upland gales.
