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 builds over the north of the UK
bringing light winds to the area signified by the widely-
spaced isobars, and keeping the frontal system to the
west of the UK at bay. Low pressure is centred over
northern France with various occluded fronts swirling
around it.
