Mon 21 Apr Strathclyde
Many areas look to be rather showery at the start of this period, with the heaviest and most frequent showers more likely in the south. With time, this showery theme should become more confined to southern areas as pressure builds from the north, and by the final weekend of April high pressure may dominate most of the UK. This means a gradual increase in the extent of dry and for some, sunny conditions, though other areas may be rather cloudy at times. Where skies are clear overnight, some late season frost remains possible. It is possible that by the end of April, warmer conditions may develop, either through increased amounts of sunshine day on day or through a southerly airflow becoming established.
