Forecast Discussion: Updated Friday, November 21, 2014 11 a.m. Local dust causing activities yesterday (especially early last evening) around the Maricopa area helped the PM10 AQI level reach the upper range of the moderate AQI category, though slightly below the Health Watch criteria of 90-100 on the AQI scale. Stagnation conditions should ease later today as an upper level low pressure trough moves through the state bringing clouds, breezy conditions and a slight chance of some precipitation, especially in the higher elevations. The winds aren’t expected to be strong enough to cause widespread blowing dust; therefore the PM10 AQI forecast is in the upper good to low moderate range on the AQI scale. A second low pressure system will skirt by to our north on Sunday. This system will have slightly stronger winds than today’s disturbance. However no widespread blowing dust is expected; therefore the PM10 AQI forecast is in a similar range on the AQI scale. High pressure will be building into the area next week so we’ll have to keep an eye on stagnation strength and local dust causing activities to see if forecasted PM10 AQI levels will need to rise into the middle and perhaps upper range of the moderate AQI category (i.e. PM10 Health Watch).
