Forecast Discussion: Updated Wednesday, September 17, 2014 11 a.m. What a difference a day makes, especially when it comes to tropical storms and the paths they take. What is now Tropical Depression Odile is taking a path farther east than originally expected. As such, the bulk of the precipitation will take place in areas south and east with the majority of central, western and northern Pinal County missing significant rains today and tonight. Some showers are still possible in those areas with heavier rains expected in southern and eastern Pinal County. The PM10 AQI levels will remain in the low/mid range of the good AQI category over the next several days due to the light rains received yesterday and today’s rains. The atmospheric conditions will dry out starting late on Thursday and lasting into the upcoming weekend. Early next week a Pacific low pressure system will skirt by to our north and may bring the chance for some precipitation. Forecaster – S. DiBiase
