This band is then expected to move very slowly eastwards during Wednesday daytime, but will break up into scattered heavy showers, with a chance for a thunderstorm or two as well.
Numerous showers and thunderstorms are forecast over Ireland and Northern Ireland, and these may be carried across parts of the North Atlantic into SW England and S Wales at times.
Showers are forecast to shrink rapidly to coastlines during the evening hours, lingering close to the south coast through the first part of the night where they may still emit thunder/lightning. Small hail, to 1cm in diameter, may accompany many of the showers over Ireland/Northern Ireland, Wales and SW England given the rPm airmass.
