Forecast Discussion: Updated Tuesday, August 4, 2015 9:45 a.m. High pressure overhead will be in control of the local weather over the next couple of days with abundant sunshine and above normal temperatures. A slight movement eastward in the high pressure will bring an uptick in atmospheric moisture as early as Thursday from areas to our south. An increase in the chances for Monsoon fueled storm development on Thursday and Friday will also bring the chance for strong outflow winds. However last Friday’s precipitation should help minimize any chance at widespread blowing dust on Thursday and Friday. The PM10 AQI forecast for today and Wednesday are in the good AQI category (excluding Cowtown) and are expected to increase into the low and perhaps mid-range of the moderate AQI category at a few locations on Thursday due to the aforementioned blowing dust. The ozone levels will remain in the good AQI category due to the unfavorable wind directions and occasional high cloudiness (especially Wednesday afternoon). Forecaster – S. DiBiase
