Headline:

Cloud and patchy light rain and drizzle in the south should soon clear to leave a mostly fine and dry day, with bright or sunny spells developing for many. Temperatures will be near average, with a light northwesterly wind. Maximum temperature 20 °C.

Monday:

A dry and bright start, before a band of cloud and outbreaks of rain, locally heavy, moves eastwards across all parts during the day. Staying on the cool side. Maximum temperature 20 °C.

Outlook for Tuesday to Thursday:

Dry with bright or sunny spells Tuesday. Cloud and rain spreads eastwards on Wednesday. Breezy too. Largely dry and bright with sunny spells Thursday, perhaps a few scattered showers. Cool.

The outlook period likely sees a continuation of the changeable conditions, with occasional bands of rain moving in from the west or northwest. There will be a good deal of dry, warm, and settled weather in between frontal systems, with the best conditions most likely in the south and east where winds will be lighter. In contrast, further north and west, it will generally be breezier, and any rain that does occur will be heaviest over the hills. Cloud cover will vary, with cloudier weather expected in the north and west, while clearer skies are likely in the south and east. Temperatures will be around or a little below average for the time of year, but on sunnier days with lighter winds, it will still feel warm or rather warm.

On balance most likely rather changeable at first, with periods of unsettled and cloudy, wet weather mixed with spells of dry and fine weather, with weather systems tending to come from the west. This means that the west is likely to see the wettest conditions, while the east will tend to be drier. By mid month there is a signal for more settled conditions to develop, so more in the way of dry weather, although still with a risk of some rain / showers at times. Temperatures close to average at first, but with a greater chance of warmer than average conditions later in the period.
