Saturday
Sunshine and a few scattered heavy afternoon showers are possible during Saturday at the moment, most of the showers focused across more inland areas of central and northern UK. The showers will be 'hit and miss' and many regions will miss them and experience a mainly dry day. Winds light and variable and still warm or regionally very warm. Highs 16C to 23C.
 

Sunday
Into Sunday and it is high pressure that is forecast to become the dominant feature of the weather once again building into the UK from the west during the day.
