Southwesterly 30 to 45mph, speed tending to rise during the day, some notable strong gusts especially eastern downslopes.
Frequent buffeting over the hills, very gusty in places affecting stability, not just highest terrain. Marked chill factor despite mild air.
A little light rain, risk wetter later west
Patches of light rain or drizzle, but periods where substantially dry, particularly more north and eastern hills. Later in daytime, risk of steadier rain moving in from the southwest into Dumfries & Galloway.
Extensive, lowest southwest
Blanket low cloud over much of Dumfries & Galloway and into the western Cheviots most or all day above 400-500m, or to lower slopes toward Solway. Some breaks above 600m toward Pentlands.

Glimpses of sun mostly toward Lothians, otherwise overcast and dull. Visibility locally good below cloud, mainly north and east, reducing in rain.

Staying unsettled with Atlantic lows dominating to the north; often windy, gale-force westerly winds for periods over higher terrain. Better weather this Sunday, then wind and rain returns into Monday, staying showery into Tuesday. A mixed outlook continues later next week with rain most frequent in western Scotland. Temperatures varying, some cooler days especially in Scotland, but often fairly mild further south, at times quite warm and humid. Higher pressure and better weather tends to expand further north later in month.
