There is a lot of people mentioning about sliders during the forecasting thread.

Can somebody please explain to me what this is / what it means :)

Many thanks in advance

A slider refers to a low pressure system that disrupts as it comes up against a high pressure block. This basically means that the low splits and sends some of its energy under the block, thus the term slider being used. These sliders can bring large snowfalls in places as the cold air remains in place. The low pressure forecast for the next couple of days is expected to do just that, so check the latest charts for an example, but with the sliding taking place to the east of the country less cold air will make it to much of the UK. If the trough disruption was happening further west then eastern Britain would remain cold with a significant snow risk.
