cloud cover

Overnight temperatures will vary depending on cloud cover but some pockets of frost are still likely, particularly in the northern half of the UK.

Showers will move northwards into Scotland during the afternoon as cloud cover becomes more widespread.

West Wales, along with central and south England, will have the best chance of the highest temperatures, but it will depend on cloud cover.

Mr Duren says that the high-resolution Tanager-1 can respond to some of these challenges, for instance by essentially sneaking peeks through gaps in cloud cover or forest cover.

But images from the EU's Sentinel radar satellites - which are low resolution but capable of penetrating cloud cover - revealed that the ships were in the military section of the port.
