A cool north-westerly pattern. Pulses of heavy showery rain spreading southwards, at times merging to constant rain around windward coasts in the north & west.

Occasional sunshine. Blustery winds and squally gusts. Temperatures just 12 to 16C.

Pressure begins to build from the west, but a cool north or north-westerly airflow continues. Showers likely to affect eastern coastal districts, plus northern Scotland, perhaps locally frequent bursts with hail and thunder possible. Snow on mountain tops. Bands of showers too for some Irish Sea coasts, moving south into Cornwall & Devon. Central-southern England generally drier with sunny spells. Highs 11 to 16C.

Confidence of detail is low. High pressure is expected to build from the south-west, resulting in a bright day for many places, with good spells of sunshine toward the south & south-west. A few areas of showers may continue, mainly around North Sea coasts, and perhaps in the far north-west. Winds easing, but staying on the cool side, highs 12 to 17C.
