UK Forecast- December 24, 2014
Sunshine and scattered showers
Turning wet & windy Boxing Day
A dry and bright Christmas Day for many, with good amounts of sunshine. A band of showery rain is expected to affect north-west England, and perhaps north Wales and may extend into the northern Midlands by afternoon. A few showers also for northern Scotland and Northern Ireland. Scattered showers may also graze down North Sea coasts, and also north-western facing coasts of Wales, Devon and Cornwall. Most precipitation will fall as rain, but occasionally over the higher ground of northern England it may turn wintry. Feeling cool, afternoon temperatures 4 to 7C.
Isolated showers will fade away overnight, with skies clearing for many. Temperatures falling quickly and there will be an early frost on Christmas night, with the risk of icy patches where showers have fallen. Temperatures widely falling to freezing, locally -3 or -4C in northern England and Scotland. High cloud tends to thicken from the west through the night, allowing temperatures to rise a little toward dawn in the west, ahead of approaching Atlantic fronts.
Low pressure moves quickly across Britain on Boxing Day. Rain will already affect most of Ireland around dawn, and soon sets in across western regions of Britain, heaviest over west Wales and Cumbria. Heavy rain spreads eastwards across England and Wales, reaching as far north as central Scotland, whilst northern Scotland should avoid most of the rain. Over the high ground of the Pennines and Southern Uplands, rain will turn increasingly to snow. Rain clears from Ireland later in the day. South-westerly winds strengthening to gale or severe gale force in the south and west. Chilly in the east and north at 4 or 5C, but climbing to 9 or 10C in the south-west later.
Low pressure moves south-east into the Low Countries during Saturday, with a belt of heavy rain clearing south away from southern England in the early hours, leaving central and southern England dry for a time. Elsewhere heavy bursts of rain encircling the low affect many areas, these turning increasingly wintry from the north. Late on Saturday evening eastern counties may see rain turning increasingly to snow to low levels, although uncertainty about the details at this stage. Gale force winds around many coasts and hills, locally severe gales toward the south-east. High seas, particularly North Sea coasts. Temperatures 3 to 6C.
