After a murky, but dry second half to the night, Sunday morning starts grey but still dry through the Central region. There will be a gradual improvement, but it will be bright rather than sunny.
By the afternoon, feeling quite pleasant with lighter winds, more brightness, local spells of sunshine but these won't be prolonged, highs 17/18c, 64f.
Monday stays fine. Although there will be weather fronts over Scotland and Northern Ireland, we will be in the warmer sector behind. The day will start slowly with low cloud around at first, but it will turn brighter later, and should feel warm in the sun. A good end to the Bank Holiday with highs up to 20c or maybe 21c, 70f - that's several degrees above seasonal average of 15c!
Tuesday sees a gradual breakdown. A dry morning, but turning wet and windy from the SW, affecting all parts later.
Wednesday, a damp start. Brightening up during the afternoon. A fresher feel to the day.
