Monday
The north to northwesterly airflow persists through Monday bringing further cold conditions. Plenty of sunshine away from coasts throughout the day. Snow showers around northern and western coasts of Ireland with further snow showers in northern Scotland and eastern England. Some snow showers through the Irish Sea too will clip west Wales into southwest England. Highs near -5C in central Scotland, widely no higher than 0 or 1C but to 5C in the far southwest of England.

Monday Night
The snow showers will moderate through the Irish Sea and in eastern England, but become more frequent in northwest Scotland as an oncoming front arrives overnight. This showery snow will progressively spread across Scotland into northern England and northern parts of Ireland through the overnight hours. Central and south parts stay dry with often-clear skies. Lows of -2 to -4C for most.

Tuesday
Another widespread and severe frost on Tuesday morning. Areas of showery snow across Scotland and northern England, these increasingly moving south, most of the showers in western areas and Ireland but also turning into sleet or rain to lower/coastal ground. Often breezy, windiest in the north, but variable. Highs at 1 to 4C, coldest in East Anglia; 5C in the far southwest, locally higher west Ireland.

Wednesday
Wednesday starts dry for many, some snow showers into north and northeast coasts. A frontal system soon brings rain to western Ireland, this spreading widely with local sleet/snow and reaching west Britain through afternoon, continuing further east into night. Precipitation largely falls as snow/sleet in northern areas, rain to the south. The east of England stays dry during daylight. Highs at 2 to 4C for most but up to 9C in the far southwest and west Ireland.
