Temperatures on the up. Air Quality goes down

Pollution levels are set to rise over the coming few days as our air moves in from the south. By the end of the week levels are expected to be high across the northwest on Friday - turning sunshine hazy and bringing a greater risk of breathing difficulties for those individuals at high risk.

As fresher and cleaner air moves in over the weekend the levels are expected to dip quite quickly from Saturday, with the air quality improving again.

THURSDAY:

High pressure moves away to the east for Thursday introducing a southeasterly flow of air. This will lead to pollution levels becoming Moderate in many parts of England and Wales, as well as parts of northern and western Scotland and the east of Northern Ireland.

OUTLOOK:

Levels of air pollution are forecast to become High across central, eastern and northern England, with locally Very High pollution levels for a time in the far southeast of England, due to a flow from the south. Further north mainly Moderate air pollution levels are forecast.

During Saturday, clearer Atlantic air will spread across all areas bringing levels down on Saturday and Sunday.
