Likely a continuation of the unsettled theme at first with further showers each day on a brisk westerly wind. Risk of some stronger winds and heavy rain around the middle of the week, although this looks a low risk at this time. Later in the period, there may be a trend toward more in the way of settled and drier interludes interspersed with further periods of rain and showers. These look more likely across southern areas of the UK, but may extend to other parts at times. Temperatures will likely be close to average or slightly below overall, but if we start to see more in the way of dry weather later in the period, temperatures could recover back to a little above average at times.
