Sun 18 Apr London and South East England

The most likely scenario for the start of this period is for mainly settled conditions to be in place across the country as high pressure continues to dominate. However unsettled conditions, rain and stronger winds, may affect the northwest during the weekend and briefly spread across many areas at the start of next week, though southeastern areas will likely remain drier and brighter. Temperatures will likely remain at or slightly below average at first, before recovering to potentially slightly above average at times. Confidence decreases after this, however towards the end of this period, it looks as though settled conditions could well return, with dry and bright weather likely. Generally, it is expected to feel rather warm, although temperatures could be supressed in wetter areas.
