Wednesday evening is showing temperatures close (or slightly below) to zero especially in England (Figure1), instead milder temperatures (6-8°C) are observed in Cornwall and N. Scotland. This is due to the clear skies, which increase the radiative cooling at surface compared with the previous days (when overcast conditions occurred).
The night on Thursday and the early morning will see clear skies mostly everywhere, only few showers might be possible in N.E. Scotland. During the morning scattered showers are still possible on N.E. Scotland and also along the coast on E. England, sunny or partly cloudy elsewhere. This is due to an occluded front positioned just east of the UK and moving towards the Atlantic (Figure2).
However, this won’t cause intense rainfall, but only showers moving westward during the afternoon (towards central-western Scotland, N. England and N. Ireland); clear skies or only few clouds in central-southern England and Wales.
Due to the still cold temperatures, some snow is possible on the highlands and N. England at (400-600 m a.s.l.).
The minimum temperatures, especially in England and Wales will be close or below zero in several places, mostly between (-2,+4 °C). Also in Scotland (mainly on the highlands) temperatures could fall below zero. The warmest areas will be N. Ireland (3-7°C) and Cornwall (3-8°C). The maximum temperatures will be steady, with no significant difference with Wednesday: in England and Wales (5-9°C), in Scotland and N. Ireland (4-8°C).
Finally, the winds will be south-easterly in S. England and easterly elsewhere, moderate on the Irish Channel (25-35 mph).
