These charts of surface pressure, from analysis (T+0) to the 84-hour forecast (T+84) are produced daily around 0730 UTC.
Low pressure over southeast Scotland dominates the UK
weather. The associated frontal system will bring showery
rain to the north, gradually moving southwards overnight.
The proximity of the isobars (thin black lines) indicates
the winds will be fresh to strong.
