Planning Outlook

Low pressure will continue to dominate the weather pattern into next week. Little change to recent patterns, with areas of slow-moving showers and thunderstorms with hail, typically most widespread in the afternoons. As the remnants of fronts circulate slowly across Britain, the intensity and extent of showers will vary from day to day, in places merging to give a few hours of constant rain, but nearby escaping drier. Winds often very light, sometimes strengthening locally. Temperatures around average for mid-May, but at times just below freezing on highest Scottish summits, resulting in occasional snow here. Existing lying snow thawing only gradually on the highest tops.
