I guess you could say it’s a brisk afternoon across the UK, particularly so over central/eastern England where mid afternoon air temperatures remain stuck at -1/-2C widely. Factor in a stiff SE wind and it feels bitter despite the absence of snow cover.
The reason for the added chill in the air is simple. Take air from a very dry, cold source across a short expanse of water and you have little modification.
Low to the west, high to the east.

You need moisture as well as below freezing air to form frost!
Not every day even in January do you see these temperatures and wind chill at 3.20pm

Nice dry, clear air will mean a cold one tonight. Wind however is likely to stop the temperature falling too far but it will feel bitter!
