Forecast Discussion: Updated Thursday, April 17, 2014 at 10 a.m. ** PM10 HEALTH WATCH IN EFFECT FRIDAY, APRIL 18, 2014 ** High pressure will briefly build into the area today and result in low/mid moderate ozone levels along with upper good to mid moderate levels of PM10. An upper level low pressure system will move into the southwestern United States on Friday and move through Arizona on Saturday. This upper level low will bring cooler temperatures, windy conditions and a slight chance for a widely scattered shower and even perhaps a thunderstorm. This morning’s University of Arizona fine resolution forecast models are showing the possibility for strong outflow winds developing over southwestern Pinal County on Friday afternoon and moving northward through the county. Therefore, as a precaution for anticipated elevated PM10 levels due to blowing dust a PM10 Health Watch is being issued for Friday. Anyone with respiratory and/or heart ailments should limit outdoor activities during periods of blowing dust. In addition, everyone is encouraged to stabilize any loose ground surfaces today in advance of tomorrow’s strong winds. A much larger and stronger low pressure system is expected to impact the area next week and bring strong winds to the area during the Tuesday/Wednesday time frame. We’ll have to keep an eye on that developing system as it may bring the need to issue a PM10 Health Watch or High Pollution Advisory. Check back on Friday for an updated air quality forecast.
