Forecast Discussion: Updated Friday, March 6, 2015 10:20 a.m. A tight pressure gradient today has resulted in breezy to downright gusty winds with gusts in Casa Grande reaching 33 mph this morning! Thankfully the recent rains have stabilized the ground enough to limit the blowing dust. Therefore the PM10 levels for today remain in the good AQI category. This weekend will feature less winds and warming temperatures. The above mentioned stabilized ground surface will help keep the PM10 levels low (good). The ozone levels will remain slightly higher than PM10 levels though still are going to be in the good AQI category. Enjoy the good air quality and beautiful weather this weekend. Forecaster – S.
