These charts of surface pressure, from analysis (T+0) to the 84-hour forecast (T+84) are produced daily around 0730 UTC.
High pressure over Scandinavia continues to dominate the
UK weather, maintaining mainly fine sunny conditions. The
through lines over south-western areas (marked in thick
black lines) indicate an area of heavy, thunder showers.
The isobars (thin black lines) show that there is an
easterly wind for most areas, as air flows clockwise
around a high pressure.
