A low pressure system positioned southwest of the UK is causing overcast conditions with showers especially in England and Wales (Figure1), with relatively cold air (especially in Scotland) coming from the Northern Sea and milder air coming from mid-Atlantic towards France and Southern Europe (see Italy weather condition).
The weather in the afternoon will see frequent showers especially in S. England and S. Wales and overcast conditions elsewhere
(few showers might be possible also in E. Scotland), though with some sunny moments in N.W. England and N.W.Scotland. On Sunday instead, a new low pressure system formed on the Bay of Biscay will move on central France (Figure2) but it won’t cause a worsening in the weather conditions, with only few showers expected in S. England and drier/sunnier conditions in Wales and Central England. Finally, some showers are expected in N.E England and Scotland due to an occluded front positioned between N.E England and the Northern Sea.
Due to the colder air, some snow is expected in Scotland and N. England above (300-500 m).
The minimum temperatures on Sunday will be between (2-8°C) in England, Wales and N. Ireland (possible frost in N.Wales and central England in case of bright skies). In Scotland values below 0°C expected in the highlands (-1,-2 °C) and between (2-7°C) on the coast. The maximum temperatures will be between (5-10°C) in England (with the highest values observed in the south-west), between (4-8°C) in Wales and N. Ireland and (2-7°C) in Scotland.
Finally, the winds will be mostly easterly and light (especially in England).
