A spell of heavy rain is likely to affect southeastern parts of England during the first half of Saturday, clearing eastwards early in the afternoon. A further 20 to 30 mm of rain is likely in places and much of this could fall within a 6-hour period. Further heavy showers may occur later on Saturday.
The public should be aware of the risk of further localised surface water flooding and disruption to travel.
A developing frontal system will move northeastwards across England and Wales on Saturday. The heaviest rain is likely to be across southeastern areas where, with ground already saturated, further localised flooding could occur.
2. Yellow warning of Snow

Outbreaks of rain, sleet and snow will develop during Saturday before clearing during the evening. The snow will be mainly confined to higher ground above about 150 metres where accumulations of several centimetres are possible. There may be temporary slight slushy deposits at lower levels in any heavier precipitation. The situation is finely-balanced and there remains considerable uncertainty regarding the extent of any snow. Hence the public should watch for further updates to this warning.
The public should be aware of possible travel disruption.
A complex depression is likely to run northeastwards across the UK on Saturday. As the associated frontal system encounters colder air across northern Britain, the rain is likely to turn to snow at least on higher routes. Any heavy precipitation could bring wet snow down to lower levels. Computer models are still giving differing indications regarding the location of the main snow risk hence there is greater than usual uncertainty over these developments. Therefore the public should keep up to date with the latest forecasts.
