The end of March will likely see a transition from unsettled conditions to predominantly dry weather with drier conditions gradually spreading in from the south, though how quickly this transition occurs is less clear and it may well be that the start of the period sees some further rain in places. Into the first week of April, settled weather is expected to cover much of the UK. Most places are expected to be dry with clear or sunny spells and light winds. Some periods of unsettled weather could develop at times and if this happens any rain or showers are most likely to affect southern areas. Temperatures will likely be close to normal overall, though some cold nights are possible at times.

Slow-moving (or blocked) weather patterns are most likely through the middle of April. High pressure located to the N of the UK will probably be dominant for much of the time, bringing a lot of fine and dry weather. If wetter, more unsettled weather develops, this is most likely to affect the south of the UK. Temperatures are likely to be close to or slightly above average overall, although some cold nights are possible.
