These charts of surface pressure, from analysis (T+0) to the 84-hour forecast (T+84) are produced daily around 0730 UTC.
Pressure remains high over parts of southern Europe and the Mediterranean, giving settled weather here, but areas of low pressure dominate much of northern and western Europe, but a weak ridge of high pressure over the British Isles is giving a drier spell here before the next weather front moves into the west later today.
