Friday 17 Dec - Friday 31 Dec
Getting into the Christmas period, it is likely to be milder than earlier in the
month, with temperatures near to above normal, although some colder spells
remain possible. It is likely to become more settled around Christmas and
towards New Year with increased chance of overnight frost and fog during
clearer spells.

Colder weather gradually after this Thursday. Thena lot of dry weather rest of the month. Mist and fog become a risk on low ground. Any snow likely after Xmas but there is still hope. At least it will be cold or even very cold.

Sunny frosty seems to be the go for Christmas at mo

high pressure in winter = no wind

cold air is heavier than warm air and so it sinks

no wind means no mixing, the warmer air rises above it so

the glens and low land pools the cold air whilst the mountain tops are in the warm air



current temp The Cairnwell (933m) the Cairngorms 14C

current temp Aberdeen -4 C
Edinburgh 1 C

-9C in Braemar this morning and 8 C on the tops of the mountains around it!

Netherlands: KNMI issues code amber warning for black ice and sleet

The warning applies to all but the southern provinces and the Wadden Sea islands, the KNMI said. The black ice will melt in most of the country as the morning progresses but there many also be wintry showers in the north, bringing sleet or a light dusting of snow.

It will be warmer on Thursday and Friday than in recent days, with the temperature rising to around 9 Celsius during the day, and remaining well above freezing at night.

On Saturday – Christmas Day – it will be chilly again, and this could lead to snow in places, the KNMI said.

From Sunday onwards, it will be grey with a 50% chance of showers on most days.
