Strongest wind in morning; local showers fade, cloud lifts.
Westerly 40-45mph early morning, tending to lessen gradually to 25mph middle of day into afternoon, 20mph later in day, particularly western hills.
Challenging conditions moderating, but still blustery and affecting comfortable walking on exposed tops. Marked wind chill.
Light showers for a time west
A little light showery rain mainly Galloway hills in the morning, fading to be often dry across the region. Some drizzly rain develops from west into night.
Lifting above the tops
Patchy cloud above 700m, most common in Galloway in the morning. Lifting and clearing above most or all hills. Into night, blanket low cloud rolls in from west.

Southwesterly 20 to 30mph, some gusty areas around some higher tops.
Varied conditions, in places fairly small, but some more blustery areas and some buffeting gusts.
Drizzle mostly west and southwest
Often drizzly much of day Dumfries and Galloway up to the M74 corridor, generally damp where in cloud, patchier drizzle north and eastwards, locally more often dry. Into night, some steadier rain develops west.
Most persistent southwest
Shrouding many hills in the morning, from lower elevations upward in southwestern areas. The base tending to drift slowly higher, but likely to persist over hills much of day near and west of M74. Breaks develop north/east areas.
20% southwest, to 50% northeast.
Largely cloudy, misty over western hills. Some glimpses of sun toward valleys in north and east, visibility good below cloud.
12C much of day, locally 14C in east, humid; then into night dropping toward 7C. Feeling like 5C directly in wind.

Warm and humid air from the southwest extends across Britain early in the new week, cloaking many hills in fog and drizzle, to lower slopes near western coasts. A band of steadier rain is likely to be draped over northwest Scotland by Tuesday. Best of cloud breaks in areas further east and northeast. Rain then passes eastwards into Wednesday followed by a few showers, lower humidity and cloud bases lifting. Later in the week, areas of low pressure toward the northwest likely still bring periods of stronger winds to Scotland at least and a risk of rain at times mainly in the west, but a trend toward higher pressure and drier weather more often for the end of September into the start of October.
