North to northeasterly 15-20mph.
Effect of the wind on you?
Mostly small
How Wet?
Little or no rain
An odd light shower may drift into northernmost mountains.
Cloud on the hills?
Banks in the north, lifting and breaking
Banks of cloud from 800m upward, mostly in the north; highest tops may be out of cloud at dawn. Higher bases and more patchy for central and south areas, little if any south. Cloud will lift and break above tops, a few caps come and go far north.
Chance of cloud free Munros?
40% north at first, rising to 90%
Sunshine and air clarity?
Intermittent or frequent sun, becoming a patchwork as fair weather cloud builds. Superb visibility.
How Cold? (at 900m)
0 or 1C at dawn, rising to 5C, some warmer patches Wester Ross and south. Little change on mountains in the far north.
Freezing Level
900-1000m, lifting off summits through morning. Highest summits of Sutherland may stay frozen.
Planning Outlook
High pressure weakens into midweek. Some passing rain/showery bursts into Wales and England on Wednesday will lead to a mostly dry Thursday and Friday. A northerly breeze will lower temperatures; freezing levels will lower to high terrain of north and east Scotland for a time. In the short-term, ground conditions remain extensively dry, water courses are very low and the fire risk is very high. Weather turns very unsettled into the weekend as a strong frontal system arrives from the west on Friday night, bringing heavy rain and strong winds to all areas. Showers and a brisk wind will follow into the weekend.
