“ The airmass will be moist and unstable, and as daytime heating gets going, heavy showers and thunderstorms are likely to break out. The exact distribution of these remains uncertain.
“They could become aligned into slow-moving bands giving some places 10-15 mm of rain in less than and hour and perhaps 30-40 mm in 3 hours in the worst affected spots.
