Forecast Discussion: Updated Tuesday, August 30, 2016 ** PM10 HEALTH WATCH IN EFFECT WEDNESDAY AUGUST 31, 2016 ** The winds have certainly picked up in intensity this morning as expected. A surface pressure gradient will continue to bring breezy to gusty easterly to southeasterly winds over the next day or two. Also, the strong easterly flow has helped bring back some atmospheric moisture. The added moisture will help scattered storms form over the mountains to the north and east and some cells may make their way down into the desert locations. Therefore windblown dust is likely and PM10 levels are expected to approach the PM10 health standard and so Wednesday’s PM10 AQI forecast has been increased into the health watch range. Therefore a PM10 Health Watch is in effect Wednesday. Anyone with respiratory and/or heart ailments should limit outdoor activities during periods of blowing dust. Less in the way of winds on Thursday and Friday as a transition to an approaching trough over the Pacific Northwest will help shift the winds to a westerly to southwesterly direction and usher in drier air. No storm activity is expected during the Friday through Sunday time period. However the winds will pick up in intensity over the weekend and so will the likelihood of blowing dust. We’ll have to keep tabs on how strong the winds will be and how likely it is for widespread blowing dust. In the meantime, both ozone and PM2.5 levels are expected to remain in the good AQI category.
