On Sunday most places will start fine, bright, and dry and remain so through much of the day, especially in northern and eastern parts. Temperatures will recover to normal or be locally warm. However, for southwestern and western parts heavy rain and some strong winds should arrive during the day as low pressure moves towards the UK from the southwest. Rain is likely to spread northward and eastwards into Monday bringing unsettled weather more widely for the start of the next week. As we head into late June there are signs that high pressure may become more dominant, bringing a chance of settled and warm weather with temperatures mostly near normal. However, by early July we may see a return to greater influence from Atlantic again, although confidence is low.

During the first half of July predictability becomes very low, with mixed signals. However, at present the favored solution is for increased Atlantic mobility through this period, bringing spells of unsettled weather to the UK, generally associated with low pressure systems, interspersed by more settled anticyclonic regimes. This will likely mean that showers or longer spells of rain will affect northwestern parts of the UK, whilst the south and southeast will see more in the way of dry weather: although some thundery outbreaks are likely in the south and southeast as is usual this time of year. Temperatures through the period will probably near or slightly above average.
