According to the National Weather Forecasting Centre of the India Meteorological Department (IMD):

Air mass inflow forecast in Delhi along with predicted ventilation coefficient and the weather forecast is as follows:

The air quality over Delhi-NCR is likely to remain in the Moderate to Poor category on 06.04.2021. The air quality is likely to improve to the Moderate category on 07.04.2021 and 08.04.2021. The Outlook for subsequent 5 Days: The air quality is likely to remain largely in the Moderate category.

The predominant surface wind is likely to be coming from the East directions of Delhi with wind speed 10-12 kph, partly cloudy sky with possibility of very light rain/drizzle towards night on 06.04.2021. The predominant surface wind is likely to be coming from Northeast/Northwest directions of Delhi with wind speed 14-20 kph, partly cloudy sky and strong surface winds (speed 20-30 kmph) during the day on 07.04.2021. The predominant surface wind is likely to be coming from North/Northwest directions of Delhi with wind speed 16-20 kph and mainly clear sky and strong surface winds (speed 20-30 kph) during the day on 08.04.2021.

The predicted maximum mixing depth is likely to be approx 4500 m on 06.04.2021, 4000 m on 07.04.2021 and 3800 m on 08.04.2021 over Delhi. The maximum Ventilation index is likely to be approx 28000 m2/s   on 06.04.2021   and   20000 m2/s   on 07.04.2021 and 17000 m2/s on 08.04.2021. The ventilation index lower than 6000 m2/s with an average wind speed of less than 10 kmph is unfavourable for dispersion of pollutants.

No significant dust transport from the neighbouring region to Delhi/NCR is likely.
