Forecast Discussion: Updated Friday, July 29, 2016 10:10 a.m. ** PM10 HEALTH WATCH IN EFFECT FRIDAY, JULY 29, 2016 ** Strong storms are expected to build over the mountains to the northeast later today and make their way southwestward and down into the desert locals. Strong outflow winds will generate dust and so the PM10 levels are expected to approach and perhaps exceed the health standard. Therefore a PM10 Health Watch remains in effect today. Anyone with respiratory and/or heart ailments should limit outdoor activities during periods of blowing dust. The weekend will also feature unsettled weather with afternoon/evening showers. The temperatures will be unseasonably cooler and the rain will go a long way towards stabilizing ground surfaces and lowering the PM10 levels. The PM2.5 levels along with ozone will also be lower this weekend and early next week. Forecaster: S. DiBiase
