On Wednesday, low cloud and areas of patchy light rain or drizzle will linger across central and southern England and Wales, gradually clearing southwards as the day progresses. Northern and western Scotland will be windy and cloudy, with outbreaks of rain and drizzle becoming more persistent
will slowly move eastward across Northern Ireland and into parts of western Scotland, with some heavy rain expected at times. The far southwest may also see a little light rain or drizzle.

in a number of different ways including from satellite data, by radar and by LiDAR (Light Detection and Ranging). The Met Office uses an instrument called LiDAR to measure ash clouds. LiDAR works by sending pulses of laser light through the atmosphere, which is scattered by volcanic ash particles. Some
