East-southeasterly 20-25mph, locally stronger on slopes nearest to the Solway; gusty in exposure.

Chance of cloud free summits?
40% east to 70% west
Sunshine and air clarity?
Glimpses of sunshine east, more often sunny west. Excellent visibility.
How Cold? (at 750m)
-1 or 0C. Feeling like -8C in direct wind.
Freezing Level
600-700m, some variability; poorly defined towards Ayrshire due to milder downslope winds.
Planning Outlook
Christmas Eve and Christmas Day will be dry: easterly winds are dominant with the strongest winds in England and Wales. Cloud may be fairly sheet-like in the east sometimes, though variably more extensive or broken, best of breaks in western areas. Turning colder too, the coldest air in England and Wales with freezing levels reaching as low as 400-600m in east Wales. Staying slightly warmer in northern Scotland with some inversion conditions likely over higher terrain; frost into glens and poorly defined freezing levels. High pressure stays put to the north into the weekend, maintaining dry weather, easterly winds, and most cloud in eastern areas. Temperatures will stay chilly.
