Heavy rain and, later, hill snow likely leads to some disruption during Tuesday and Wednesday.
Persistent, and at times heavy rain will develop across Northern Ireland, southern Scotland and the far north of England during Monday night.
Rainfall accumulations of 20-30 mm are expected quite widely and some places, mostly over higher ground, could see 30-50 mm rain. This wet weather will clear eastwards early on Wednesday.
Later on, Tuesday rain will also turn to snow over hills, initially down to 300-400 m and then down to 100-200 m Tuesday evening and night.
The most widespread snow will be over southern Scotland where accumulations of 2-5 cm are possible above 200-300 m and 5-10 cm may fall above 300-400 m.
