Latest Forecast Summary

Today

Air pollution is expected to be Low at urban, rural and roadside locations across the UK for the next 24 hours as a period of showery and windy weather affects the country. 
The situation is expected to remain unchanged for the following few days.

Thursday

Air pollution is expected to remain Low at all locations across the country for the next 24 hours as a period of cloudy and windy weather affects the UK.
The situation is expected to remain unchanged for the following few days.

Outlook

The weather for the next few days is forecast to be cool and very unsettled. Brighter and drier weather is forecast in western areas of the UK but still with showers and rain at times. Periods of prolonged rain and showers but also some good brighter spells are expected in eastern parts of the country. It will be rather windy but most especially in eastern parts where there will be a risk of gales in exposed areas. Temperatures are expected to remain in the double figures.

Forecast air mass back trajectories indicate that the majority of incoming air masses will be arriving from the North Atlantic. Currently all pollutants remain low at all AURN sites and CMAQ model forecasts low levels of pollution across the UK during the forecast period. Under the unsettled weather conditions it is very likely that any locally emitted pollutants will quickly disperse.
