These charts of surface pressure, from analysis (T+0) to the 84-hour forecast (T+84) are produced daily around 0730 UTC.
A ridge of high pressure extends across the UK, bringing
a fine day to much of the country with good spells of
sunshine throughout the day. However, a cold front to the
northwest of the UK brought thicker cloud and some patchy
light rain to western parts of Northern Ireland and the
far northwest of Scotland.
