Weather Watch for Snow/Ice:
An active cold front has swept south-eastwards across the UK this morning introducing a much colder and increasingly unstable air mass in from the northwest which will result in heavy and frequent showers developing and these will turn increasingly wintry with snow even falling to lower levels at times.
The showers are expected to develop across many northern and western areas during Wednesday morning so that by Wednesday afternoon hail, sleet and snow showers are expected to affect many these regions with snow settling, especially over higher ground. These showers will be accompanied by strong to gale force west/north-westerly winds which will lead to blizzard like conditions over the mountains and poor visibilities during the heavier showers elsewhere whilst the winds will also assist in helping showers spread further inland at times.
The main regions at risk from settling snow during Wednesday look to be northern and western Scotland, Northern Ireland, northwest England, before the risk extends further south into Wales and the moors of southwest England by Wednesday night. For low levels accumulations of 2-5cm of snow are possible from late Wednesday into Thursday, but over high ground above around 200m 5-15cm of snow is likely in places, and perhaps over 20cm in localised spots. Please monitor forecasts closely as snowy conditions are likely to affect the Wednesday evening and Thursday morning rush hours in the above regions, especially over higher routes where conditions will become hazardous.
With temperatures falling down close to or below freezing, icy surfaces are likely to become an additional hazard.

Weather Watch for Snow/Ice
After a brief period where slightly less cold air moves across the UK turning showers back to rain on Friday and Saturday, we are expecting a very cold airmass to sink southwards from the north later on Saturday and into Sunday as winds veer more northerly in direction.
With the cold, unstable airmass and warm sea surface temperatures, we are expecting heavy and frequent showers to develop, especially around the northern coasts of Scotland and Northern Ireland, but also down the west and east coasts of England and Wales. It will be cold enough for snow to fall to low levels, and accumulations are likely to develop. In addition to this, the development of troughs, which won't be identified until nearer the time, could bring the risk of snow to inland regions too.
We will update this Weather Watch as developments become clearer.
