Forecast Discussion: Updated Tuesday, September 30, 2014 10:30 a.m. The next several days will feature quiet weather with pleasant temperatures. A trough will skirt by the Four-Corner area late on Wednesday/early Thursday. 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 AQI forecast reflects the possibility of blowing dust on Thursday, especially around the Eleven Mile Corner area. The temperatures will be on the rise through the second half of the work week and into the upcoming weekend. After the morning breeziness on Thursday and Friday, lighter winds and less dust causing activities will mean PM10 levels will all be in the good AQI category. Ozone will also be in the good category due to the decreasing amount of sunlight this time of year. Forecaster – S. DiBiase
