The air influx will still be relatively clean over the weekend, however Saturday is expected to be hot and sunny, conducive to the atmospheric photochemistry responsible for ozone production. Therefore moderate ozone levels may be reached on Saturday.

The hot weather will continue on Sunday, cooling slightly by Monday, but the increased cloud and possibility of rain will limit ozone production for the rest of the weekend.

Pollution is expected to remain 'low' for the following pollutants:

PM10 particulate
PM2.5 particulate
