Cloudy conditions with rain at times will continue in Scotland and Northern Ireland with winds strong to gale rom south-west and west, some improvement is probable in the west and North tomorrow.

Fog will thicken over England as the milder south-westerly current sets in. It will be rather cold at first in the North, but will be come milder. In the South it will be very cold with severe frost this evening, but it will be come less cold later.
