Deteriorating - early in the day on many more western areas - as strengthening winds, rain and low cloud associated with a front extends slowly eastwards. The rain will amount to little southern Pennines, and largely dry until later in the day northern Scotland (where precipitation initially snow on the Munros).
Increasingly windy; rain, mainly more southern summits.
South to southeasterly between 10 and 20mph morning but slowly strengthening to between 20 and sometimes 30mph afternoon.
Small morning, before base of walking increasingly impeded by the wind and notable wind chill develops.
Increasingly wet; particularly southern Cairngorms NP
Substantially dry at first, but from the south, rain, or initially above 750m snow, becoming extensive and for periods heavy, particularly west of A9. Least rainfall northern Cairngorms and particularly north and east from Braemar.
Becoming extensive across higher areas in rain
Monadhliath east to Cairngorms and Lochnagar: Summits extensively cloud free before in rain, cloud base drop to between 750 and 1000m. West from southern summits in Cairngorms NP: cloud soon extensive above 600m, and patches nearer 450m at times.
60% dropping to almost nil south and 20% more northern summits
Extensively sunless - but a few glimpses lower slopes Cairngorms and Deeside. Visibility deteriorating to become extensively poor in rain.
0C rising to 4C. Will feel as cold as minus 9C directly in the wind.
900m, gradually lifting above the summits from the south. Frost in many valleys post dawn.

Southeasterly between 10 and 20mph: generally strongest in the morning.
Small
Little or no rain
Risk of one or two showers, but most or all areas dry.
Mostly very little
From dawn very varied cloud base, in places covering lowest slopes (sometimes higher slopes between cloud layers). Slowly the cloud will break up; by early afternoon, nearly all summits cloud free.
30% rising to 80%
Cloud layers gradually thinning and breaking to give a patchwork of sun. Excellent visibility.
6C rising toward 10C
Above the summits.
Considerably warmer this week. Rain from time to time, although from Wednesday largely dry in Scotland and perhaps N England - although the risk of bursts of rain, perhaps thunder. Wales will be most prone to further rain. As yet, considerable uncertainty in the detail next weekend, although ensemble of forecast models suggest light wind, fairly warm with some sunshine. Most uncertain is the extent and locations of possible showery rain or thunderstorms.
