Forecast Discussion: Thanks to drying in the mid-levels between five and ten thousand feet off the surface a shutdown in storm activity is expected through Thursday. With an easterly air mass push underway from southern California, the attention now turns to ozone, rather than PM-10 for the Yuma area. Ozone levels are expected to rise today and enter the middle to upper Moderate category by Wednesday. Other factors that will help maximize ozone concentrations are mostly clear skies and unimpressive vertical mixing. Ozone was decreased on Thursday in anticipation of a wind shift more out of the south, cutting the link from California. There is some uncertainty in the timing for the winds to change direction, however, so Moderate ozone levels are still being forecasted for Thursday. Check back tomorrow for more. Until then, have a good day! -J.Malloy
