[South East and East Anglia Weather Discussion January 2021 onwards]

I can tell from my conservatory door being difficult to close and lock that the temperature in Caterham Valley is probably -4 to -5 currently (the door metal shrinks).
However due to very low humidity it doesn't actually feel that cold.

Temps dropped rapidly when the rain cleared didn't they? Little wind across the SE now, northerly polar flow across the Channel undercutting the rain shield, cold air aloft quite deep above shallow surface layer with little warmth left from earlier maritime flow incursion as polar air mixes it out from the NW, so any heavy ppn is going easily drop the temperature by a few degrees through evaporative cooling. Only 2.3C here at Caterham-on-the-hill.

Cold in the Valley also

Afternoon.

Currentlt 6.6c & heavy rain.

However the colder & clearer air is starting now to push East so those winds will die out for around 6pm.

Reports of rain turning to snow in wales thread is good news.

The system that is bringing the wintey potential for tomorrow is now in radar range.

It is snowing just west of Cork in Ireland, they very rarely get snow.
So the system coming in tomorrow has very cold air associated with it.
