Planning Outlook

Atlantic weather patterns and generally westerly wind will be dominant in the foreseeable future. The weekend ahead is increasingly unsettled, widespread gales on Easter with storm-force wind in Scotland, cooler temperatures, and showers west. Into next week, temperature and wind will be variable, periods of gales and possibly often cold over the mountains with snow and hail showers at times to lower elevations at least in Scotland, sometimes more widely. Precipitation generally most frequent west and northwest, though bands of heavy rain will sweep east at times. Some brief windows of drier and brighter conditions, as well as milder days in England and Wales, occasionally milder Scotland too, but soon followed by more Atlantic low pressure systems.
