Low pressure remains over the UK during Thursday with a trough moving through central parts of the UK. This will bring patchy rain across the Midlands, northern England and Wales before moving into East Anglia into the afternoon. Largely dry elsewhere but some showers developing across Scotland and southern counties of England. Brighter conditions will be developing from the west. During the afternoon there is the potential for some scattered slow moving thunderstorms to develop across the central and eastern parts of England, these locally torrential, although fading quickly once again from the west during the later afternoon and evening. Drier with sunny spells elsewhere. Highs around 14 to 18C generally and 21C in the southeast of England.

Temperatures falling to around 12 to 15C. Cooler across central Scotland with temperatures falling to 7 to 9C.

Behind the rain, low cloud, mist, fog and drizzle will linger on western coasts of the UK as well as western coasts of Ireland. The south does look to stay mainly dry although on that brisk west to southwesterly wind blustery showers are likely to reach central places across England. Best of any sunny spells will be in the southeast of England. Highs around 14 to 18C generally with the southeast fairing warmer at 21C.
