Very cold and windy with plenty of snow showers.
Very cold and windy. Some sunny breaks but plenty of snow showers feeding in the from the east. The snow will be heavy at times, especially towards the north, with the strongest winds to the west of high ground. Maximum Temperature 4C.
Further snow showers overnight with the potential for some more persistent snow to push up from the south by dawn. Staying windy. Minimum Temperature -6C.
The spell of more persistent snow will gradually clear westwards through the day, and will turn more to rain especially near the coasts. It will still be cold and windy. Maximum Temperature 2C.
Outlook for Monday to Wednesday:
Mostly dry through Monday and Tuesday though thawing snow will bring the risk of ice as temperatures only slowly recover. Perhaps some in the north rain by Wednesday.
Day 6 to 15
There will be a frosty start for some on Wednesday, especially in the east. Otherwise it will be a largely dry day with sunny spells for many before strong winds and a band of rain pushes into the northwest later. This band of cloud and rain will then spread across all parts on Thursday, followed by blustery showers in the west. Low pressure is then likely to be in charge of our weather for the rest of the period bringing spells of rain, especially across the south and southwest. Inbetween spells of rain there will be some drier, brighter and colder interludes. After a cold start to this period, temperatures will tend to recover before it then turns rather cold from the west again later, giving a chance of frost.
Day 16 to 30
There is significant uncertainty in the forecast throughout this period, but a blocked or slowly changing weather pattern is probable. There will most likely be a balance between Atlantic frontal systems affecting the south and west at times with colder air associated with high pressure out to the northeast. Mixed conditions are likely with wetter than average conditions expected across the south, while staying drier and perhaps colder to the north. Further snow is possible, especially in the north where it will also be windy at times. Temperatures will likely be below average with further night frosts, and any milder interludes will probably be only brief.
