Wednesday 17/01/18
A similar pattern, with an unstable westerly airstream producing heavy and squally showers - of snow or hail again to low levels. Eastern regions will stay driest, with spells of sunshine. Staying windy, and feeling cold. Later, a frontal system may move into Ireland, then western Britain, bringing a risk of persistent rain, or snow over high ground. Highs 2 to 5C.

Thursday 18/01/18
An active area of low pressure is expected to pass quickly eastwards across the British Isles, probably early in the day. A risk of widespread gales. A period of rain in the south, but a threat of disruptive snow across northern regions. Clusters of heavy wintry showers will follow from the west. Temperatures ranging from close to freezing in the north, but may rise briefly to 8 to 10C in the south.

Friday 19/01/18
A chilly west to northwesterly pattern is likely, bringing further wintry showers, most frequent around western coasts, but some advancing well inland, giving snow and hail to low levels. Sunny spells best toward central and eastern areas, where it may stay dry all day. Local frost and a risk of ice in the morning. Feeling cold in the wind. Highs 2 to 6C.

Saturday 20/01/18
The wind is likely to turn northwesterly, maintaining cold conditions. Snow and hail showers focused around coasts in the east, west & north. A few bands of showers may move into the Midlands from the north-west. Many central-southern districts should stay dry with winter sunshine. Highs 1 to 5C.

Sunday 21/01/18
Staying cold, with snow showers probably confined to North Sea coasts, although a few may continue locally around the Irish Sea. A front may encroach into Ireland from the south-west, bringing a risk of rain here. Sunshine for many areas. Widespread frost and ice overnight. Highs 1 to 5C.

Monday 22/01/18
Confidence is low. A frontal system may try to make inroads from the south-west, bringing a risk of rain preceded by snow. Likely to remain chilly, with widespread frost. Just 1 or 2C for some but may rise to 5 to 8C in the south-west.
