Planning Outlook
Several cores of low pressure are circulating around the British Isles through the weekend and into next week. Western areas are likely to see rain with a few stray showers into the east. High pressure will briefly build in on Easter, settling the weather momentarily. Southern areas will see showers into early next week and low pressure will become dominant in the Atlantic, which may push several bands of rain eastward toward the British Isles, though details remain uncertain at this point. Temperatures will be near average or slightly cooler, depending on the position of low pressure.
