Sunday: Patchy outbreaks of rain affect the northwest during the early part of the day but elsewhere it becomes mostly and bright. During the afternoon wet and windy weather pushes into the far north west with gales or even severe gales possible.
Monday, Tuesday, Wednesday, Thursday: At the start of the period rain clears southeastwards and is followed by showery weather. Through the rest of the week it stays cold and showery. It will be windy and there is a likelihood of showers turning wintry at times even in the south. Accumulating snow is most likely in central and northern areas and especially over higher ground where heavy falls are expected.
Forecast confidence is high falling to moderate later on.
Quite cold and changeable.
A rather cold week is favoured. All regions could have wintry showers and longer spells of rain, sleet or snow. During quieter interludes nighttime frosts could be widespread. The greatest risk of snow is over high ground in the north but it may be cold enough for snow to fall in southern counties at times, especially over high ground such as the Cotswolds and Chilterns.
Forecast confidence is low to moderate.
At the start of the forecast period the UK will be sandwiched between high pressure to the east and low pressure areas to the west. After the first few days a transition to an Atlantic based pattern takes places. A rather cold west or northwesterly flow then becomes established and probably continues for much of the period. There is a high probability of disruptive snowfall over high ground in the north but marginal conditions mean there is uncertainty about the snow risk over lower ground and in the south. A cold west or northwesterly air stream brings showery conditions for much of the forecast period. The showers often fall as snow in the north and perhaps in southern counties at times.
Points of note
Heatingoilshop.com highly recommends a #heatingoil tank level check every two days especially if the levels are below 40% full. At 25% full, the advice is get multiple #heatingoilquotes from heatingoilshop.com from local suppliers to your area. Make sure you get #heatingoilprices that reflect your anticipated delivery day. Emergency fills cost a lot more so pre-order in advance for a lower price. It really does depend on how much time you have left with the levels in your #heatingoil tank.
