to the formation of cumulonimbus clouds, towering, dense clouds capable of producing heavy rain, hail, and lightning. Lightning is a massive electrical discharge caused by the separation of positive and negative charges within a storm cloud. As the storm develops, ice particles and hailstones collide

infrastructure potentially causing travel disruption. It starts life as snow, ice, or hail, which melts as it passes through a band of warm air as it falls, before refreezing in a band of colder air. The rain droplets become 'supercooled' and are close to or below freezing when they hit the ground

: “The low pressure that brought the snow and heavy rain in the south will move out to the east by Monday. This will allow a cold northerly flow to become established again for much of next week. This will bring further sleet, snow and hail showers to northern Scotland in particular, but possibly

It's staying warm with sunny spells for large areas over the next few days; however, many of us will continue to see thunderstorms with torrential rain, lightning and hail.

to fall in an hour, and a chance of some isolated places seeing as much as 60-80 mm over two to three hours. Some will see frequent lightning and large hail as well. This could result in flash flooding, transport delays and dangerous driving conditions, especially on the M4 and M5. “We’d advise

and northern England where there is a Met Office Weather Warning in force.  Whilst many places will remain dry and hot, the thunderstorms on Friday could lead to torrential downpours in places with a much as 30 mm of rainfall in an hour and 60 mm in 3 hours.

Little snow is likely to settle at low levels by day, but through the evening and overnight, 1 to 3 cm may accumulate in some places within the warning
