Forecast Discussion: Updated Wednesday, October 1, 2014 10 a.m. A trough will skirt by the Four-Corner area over the next day or so. Surface high pressure will build in behind it which will create a rather tight pressure gradient on Thursday and slightly less so on Friday. Breezy northeasterly winds Thursday morning and easterly breeziness on Friday morning (though not quite as strong) may create some localized blowing dust over the eastern half of the county. The PM10 levels may rise a bit in the Eleven Mile Corner and San Tan Valley areas; however the AQI levels are expected to remain in the good category on Thursday and Friday. Ozone will also be in the good category due to the decreasing amount of sunlight this time of year. Forecaster – S. DiBiase
