Forecast Discussion: Updated Tuesday, November 25, 2014 10:10 a.m. Some morning easterly to northeasterly breeziness today will give way to lighter winds later in the day. Some localized blowing dust is possible this morning, though the PM10 AQI forecast for today remains in the upper good to low moderate range on the AQI scale. The cold temperatures over the next day or so will be replaced with warming temperatures on Wednesday through Friday as high pressure briefly builds into the area. A morning pressure gradient on Thursday may create breezy enough conditions to cause localized blowing dust in areas. The PM10 AQI forecast for Thanksgiving will remain in the upper good to low moderate range on the AQI scale since dust causing activities will be minimal along with the winds which are expected to diminish as the holiday unfolds. A large upper level low pressure system over the Pacific Northwest is expected to dip southward and move into the area early next week. We’ll have to keep an eye on that system as it develops to see what potential impacts wind-wise (and blowing dust wise) it may have on the area. In the meantime, enjoy the abundant sunshine and beautiful temperatures. Forecaster – S. DiBiase
