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 to the south of the UK continues
to decline. Low pressure to the northwest of Scotland
dominates the UK weather with the associated series of
weakening fronts bringing bands of showery rain across
the UK. The isobars (thin black lines) indicate a
moderate to fresh westerly breeze as wind circulates in
an anti-clockwise direction around a low pressure.
