Thunderstorms and rain will be possible today, including in the afternoon and overnight into tomorrow morning. More storm activity will also be possible later this week.
Overall, rain will help to keep PM10 (dust) and PM2.5 (smoke) levels low. Though, we can't rule out locally elevated levels of PM when conditions are calm in the mornings. Both pollutants are forecast in the Good AQI category each day.
Check back again tomorrow morning for the latest.
