Tuesday 16/01/18
Low pressure centred north of Britain and high pressure around the Azores produces a strong westerly wind. Widespread and frequent heavy showers, merging to constant precipitation in all western regions - snow or hail falling to low levels, accumulating over the hills. Possible thunder, especially near western coasts. A risk of ice. Brighter toward the east, with sunny intervals. Temperatures 2 to 5C, but feeling sub-zero in the wind.

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
Confidence is low, but an active area of low pressure may pass quickly eastwards across the British Isles. A risk of gales, especially in the south & west. A period of rain in the south, but a threat of disruptive snow across northern and perhaps central regions. Temperatures ranging from close to freezing in the north, up to 8C 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 advancing well inland, giving snow and hail to low levels. Sunny spells toward central and eastern areas. Highs 1 to 5C.

Saturday 20/01/18
The wind is likely to turn northerly, maintaining cold conditions. Snow and hail showers focused around coasts in the east, west & north, whilst central and southern districts should stay dry with winter sunshine. Highs 0 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. Sunshine for many areas. Frost and ice overnight. Highs 0 to 4C.
