The AQI could improve to “moderate” or “satisfactory” by Wednesday night due to projected rainfall and related wet precipitation, the air quality monitoring agency Air Quality and Weather Forecasting and Research said Tuesday. “From Thursday, relatively high winds are likely to enhance dispersion and keep the AQI at ‘moderate’ or ‘low-end differential’.”
Wednesday could see a low of 13C and a high of 21C. Tuesday saw a low of 11.5C and a high of 26C, 3C above normal. Dense fog is possible on Thursday morning, with a low of 8C expected and a high of 22C.
