Forecast Discussion: Updated Friday, August 1, 2014 10:45 a.m. The late night storms last night did occur as expected, however the outflow winds weren’t quite as strong as expected. That combined with some ground stabilization due to recent rains appears to have helped keep the PM10 levels below the forecasted levels. Additional rains occurred during the overnight and early morning period with some areas receiving over a tenth of an inch of rain up to almost half an inch. Needless to say the PM10 level are low so far today and are expected to stay low due to the wet ground surfaces. Therefore the PM10 Health Watch originally issued for today has been cancelled. More rain is expected over the weekend as an upper level low pressure system moves through the state. Some areas could get close to an inch of rain before all is said and done. So the forecasted PM10 levels are all in the good AQI category. Conditions will dry out and warm up next week. In the meantime, enjoy the relatively good air quality. Forecaster – S. DiBiase
